The basal metabolic rate per gram of body weight is seven times greater in mice than in humans. Organisms with large mass-specific metabolic rates typically show relatively large deviations from "normal" values because of a weak capacity to maintain homeostasis. Mice, which have a higher mass-specific metabolic rate, have a weak capacity to maintain cellular homeostasis; humans have a lower mass-specific metabolic rate, and a strong capacity to maintain cellular homeostasis. Mice are not small people, and "everyone else did it" is not a sound experimental design rationale.
Results of meta-analysis of 12 large studies conducted between 1966 and 2008, covering more than 1.5 million subjects, were published in the British Journal of Nutrition in 2009. The authors concluded that the Mediterranean diet is associated with significant health benefits, including lower mortality overall, and reduced risk of chronic diseases like heart disease, cancer, Alzheimer’s and Parkinson’s.
She recommends eating outdoors, using our lunch hour to incorporate a half-hour walk with a friend, turning off electronics at meals, and stepping outside for walk after meals. I have to tell you, I felt like I was 12 when we put the “no electronics” rule back into play at my home. Dessert used to be my thing after dinner, now it’s taking a walk around the neighborhood with my son or girlfriend.
"What I don't like about any commercial diet is that the focus is not on your actual food choices," Hogan said. "It's about calories or points or numbers, and that really takes away from your ability to be in tune with your hunger cues and your fullness cues and what you're really craving. If we become more in tune with those things, we naturally consume how much the body needs. Paying too much attention to numbers takes away from that."
We’ve said it before and we’ll say it again: fat is your friend! To be more specific, healthy fats will be your weight loss friends. Consider adding extra virgin olive oil to your diet and you might see the scale start to tip in your favor. One Journal of Women’s Health study discovered that an EVOO-enriched diet helped participants lose more weight than those on a low-fat diet. Like peanuts and avocados, extra virgin olive oil’s belly-blasting abilities are thought to be a result of the monounsaturated fats it contains.
Spirulina is a high-protein seaweed supplement that’s typically dried and sold in powdered form. The dried stuff is about 60 percent protein, and, like quinoa, it’s a complete protein, meaning it can be converted directly into muscle in the body and is thus a great weight loss tool. A tablespoon of the blue-green algae delivers 8 grams of metabolism-boosting protein for just 43 calories, plus half a day’s allotment of vitamin B12, which in and of itself can give you more energy and boost your metabolism. Try tossing some spirulina into a smoothie and watching the pounds melt off. For more skinny smoothie ideas, check out this list of 56 Smoothies for Weight Loss!
For me, I chose to become a CDE because I had worked as a Registered Nurse first on a medical unit, then in a Medical ICU. These are the units where most of the people with diabetes are, so I had seen every horrific complication that diabetes can cause. When I had a chance to become a Diabetes Educator…to actually help PREVENT some of those horrible complications…I jumped at the chance!
You are so biased against Keto, this can be noticed very quickly because almost every positive thing you say about Keto, you immediately follow with a “but…” negative statement. And most of your negatives are simply saying it’s hard to maintain. You completely exaggerate the negatives “If you have one bad day and your body is kicked out of Ketosis, you immediately gain all of your weight back”. That is simply not true; if someone is on a Keto diet for 3 months, they will not gain that weight back in a day. Also, their body will be back into Ketosis the next morning. You say that the ADA doesn’t recommend 60-70 grams per meal, but it does (coincidentally I just left their website before coming here). I don’t claim to be a Diabetes expert; I admit that. But your bias is leaning heavily against Keto. “Moderation” is not your goal if you have diabetes. When you compare HbA1C levels, for example, you compare them with someone in Keto at less than 20 g of Carbs per day as compared to someone at a 70-90 gram of carbs per day diet. You should be fair and compare them with someone on a 200 g of Carbs diet. If you want to get rid of the effects of Diabetes, get on a Keto Diet, period. It MAY get rid of the effects completely, but in the very least it WILL reduce your Insulin needs to very low and you’ll have little-to-no side effects other than a relatively restrictive diet (most diets are WAY more restrictive than Keto). You back up everything with “science” and misleading numbers/arguments without providing any real evidence.
Kefir is a yogurt-like substance, but it actually contains less sugar and more protein than conventional yogurt while remaining packed with gut-friendly probiotics that can help you lose weight by aiding digestion. In one study, kefir displayed weight loss properties similar to those of milk and other dairy-rich products. Other probiotic-rich foods include kombucha, bone broth, and fermented items such as sauerkraut and kimchi.
It’s only dangerous to not get enough carbs at each meal if one is taking too much meds or insulin for the amount of carbs they are eating! Restricting carbohydrates doesn’t lead to hypoglycemia unawareness, but having lots of lows and lots of highs will (and decreasing insulin and carbs leads to way fewer highs and fewer lows, or at least it can). On the other hand, being in ketosis does make low blood sugars less negative as an experience. I still feel my lows just fine, but they are less of an emergency because my brain still works (feeding on ketones) and by body doesn’t freak out and release tons of adrenaline that then makes me want to eat a house. Mind you, I still wake up and know immediately if I’m low, I know from experience and how it feels in my head and body but without the crazy shakes. This is not unawareness but it is less reactive.
This is a great site for information, details, recipes, etc… one of the reasons I started looking into this way of eating is my husband suffers from high blood pressure, cholesterol and type 2 diabetes. We are not exceptionally overweight, however could both use to lose 10-15 lbs/ea. I also have facial and ocular rosacea and have heard good things about this way of eating for an overall improvement in numerous areas. Although I may have missed it I haven’t seen anywhere you might have mentioned your weightloss success. Thank you for sharing your wealth of information.
Sautéed carrots and onions. Sauté 1 medium onion, thinly sliced, in 1 tablespoon olive oil or canola oil. Add about 8 ounces sliced carrots, and continue to sauté until the carrots are soft. Add 1 thin pat of butter at the end. (Hints: Top the turkey with the sautéed carrots for extra flavor. If you like very soft carrots, microwave first before sautéing.)
Iwould hope to meet a diabetic nurse in the uk who was open minded about keto, but that has not been my experience as a patient. As a nurse speaking to colleagues as an equal and frmy experience has been very different. I have not spoken to one nurse with personal/professional interest in this subject that has said if they were diabetic they would follow the guidance of our health service. All have said they would do keto.
Created in 2003 by cardiologist Arthur Agatston, this low-carb diet features three phases. The first phase is the most restrictive, limiting carbs such as potatoes and rice. Each subsequent phase becomes more lenient, and the diet emphasizes lean protein, unsaturated fats, and low-glycemic carbs such as nonstarchy vegetables. South Beach promotes lasting lifestyle changes, according to the Mayo Clinic. (21)
It is important to note that the research did not analyze whether the diet employed causes obesity, if given long term. The mechanism behind the whole process was undetermined; therefore, the existence of a shared physiological response between low carb and regular carb high fat diets that cause insulin resistance in the liver requires further exploration.
Following are two examples of menus from the book, The DASH Diet Weight Loss Solution. It features 28 days of meal plans, to help you visualize a variety of ways to put together the DASH diet. They are suggestions, and you are free to make substitutions with your favorite foods that have similar nutritional properties. This is part of the way that you will learn how to make the DASH diet into your own personal plan.
Interested in following a more historical approach to eating? The Primal Blueprint is similar to the Paleo diet, which has roots in how our long-ago ancestors supposedly ate. This plan ditches grain, sugars, and processed foods while focusing on clean eating with plenty of protein (both animal- and plant-based), lots of vegetables, fruits, and healthy fats. The Primal Blueprint acknowledges other health factors too, advocating for lots of low-intensity activity, some high-intensity exercise, strength training, and plenty of sleep.
Other diabetes medications. Insulin-releasing tablets (e.g. sulphonylureas) often lead to weight gain. These include: Minodiab, Euglucon, Daonil, and Glibenclamide. Tablets like Avandia, Actos, Starlix and NovoNorm also encourage weight gain. But not Metformin. The newer drugs Victoza and Byetta (injectable) often lead to weight loss, but possible long-term side effects are still unknown. More on diabetes
“A lot of people think the foundation of a paleo diet is high-fat meat, but I suggest that it’s vegetables,” says Hultin. The concept is to eat only foods — including meat, fish, poultry, eggs, fruits, and vegetables — that would have been available to our Paleolithic ancestors. This means grains, dairy, legumes, added sugar, and salt are all no-no’s.
The comments defending the keto diet suggest that the individuals are successfully using the keto diet to help them maintain a healthy weight and a healthier A1C level. The individuals also suggest that they view it as a way of life rather than a diet. This is good news for many of us who are facing the question of whether it will be helpful and necessary to reduce carbohydrate intake to keto producing levels in order to halt or reverse the onset of type II diabetes. I think like those individuals, Tami is speaking from her own personal experience where she had success losing weight, but had difficulty maintaining the keto diet long-term. I am sure that though you have been successful, you can understand that there are many who might find it difficult to maintain. I too have been given very bad guidance by Medical Doctors who lean on old Med School information to practice medicine rather than continuing to broaden their knowledge base and learn more about nutrition. I cannot get back the 20+ years of suffering with a debilitating disease that could have been cured because my doctors were not well informed or willing to listen to information that disagreed with their limited knowledge base. Those years are gone and the destruction to my body is not reversible. So I understand the anger you feel toward a system that isn’t working in the best interest of the patient. But I think that expressing anger toward those who disagree with our personal experience, is not solving the problem. Hopefully we can change the ADA guidelines by respectfully urging them to reconsider their position based on the sheer volume of the comments they receive from successful people like you, who are living the keto diet lifestyle and living better. I commend you for becoming your own best health advocates. Thanks for your encouragement and your passion. And thanks to Tami as well for sharing her personal experience and the information she had collected. We all have to be true to what we believe and we all have a right to come to our own conclusions. It is good to know that there are success stories out there. I wish you all good health and continued success. I also hope that one day medical training will do a much better job of preparing doctors to become their patient’s best advocates, actively learning and searching for cures rather than treating symptoms in ways that cause even more disease to develop. The system is failing so many of us.
A majority of the meal planning for the Mediterranean diet consists of fresh fruits and vegetables. A sample days meal menu consists of: a pumpkin-gingerbread smoothie for breakfast, Macaroni with Milk (Macoroni oil-Hali) for lunch, and Trout with Wilted Greens for dinner. Your suggested snacks during the day: Mango-Pear Smoothie, cashews and raisins, low-fat ricotta cheese with peaches, hummus, and seed and nut snack bars.
With fats being my main source of calories, my body and energy levels have never been better. When I educated myself on it and understood the science behind it, it was clear to see why my joints started feeling better, and ailments started to go away. I now have more “oil” lubricating my cells so they’re more receptive/flexible/malleable to the nutrients in my foods. People can loose weight very fast, but honestly the first 10lbs or so is a lot of water weight so that’s really nothing to write home about.
First – let’s admit that there are several different types of diets that produce dramatic improvements in weight loss and diabetes. The vegan diet is one of them (and one which also reduces risk in most other diseases better than the others) – but it is by unquestionably by far the very best diet for the environment and the survival of the planet. High protein (high meat and/or dairy) diets are absolutely TERRIBLE for the environment and are not sustainable in any way. A vegetable diet will END world hunger because we DO have enough earth to grow enough vegetables for everyone and we definitely do NOT have enough earth for meat eaters even at current levels.
Well, I am going to give this another try. I have great difficulty in eating greens , or drinking them, also I am not fond of fats, years and years of low fat diets have totally screwed my metabolism,and taste buds. I will read this page every day to keep my mind focused. Start tomorrow when I get up …… I work nights which can cause me problems as well. When I tried this diet before, I got terrible cramp, now I realise I wasn’t drinking enough water. Anyway.here goes.
What the diet advocate says: ‘We are committed to always being the best weight management program on the planet, but now we’re putting our decades of knowledge and expertise in behavioral science to work for an even greater mission,’ says Mindy Grossman, President and Chief Executive Officer, WW. ‘We are becoming the world’s partner in wellness. No matter what your goal is – to lose weight, eat healthier, move more, develop a positive mind-set, or all of the above – we will deliver science-based solutions that fit into people’s lives.’
At the end of this 12 week study, scientists observed similar loss in body fat and overall body weight in all three diets. However, they noted that the VLCARB ketogenic diet was “more effective in improving tracylglycerols, HDL cholesterol, fasting and post-meal glucose and insulin concentrations. More specifically, triacylglycerols decreased by 39.9% in VLCARB subjects, 4.0% in VLF subjects, and 9.6% in HUF subjects. 
A relatively new offering, the Nutritarian diet is based on maximizing the amount of healthy vitamins, minerals, and trace nutrients in your food, balancing your hormones, and avoiding toxins. The plan—created by Joel Fuhrman, M.D., author of The End of Dieting—is nutrient-dense, plant-rich, and includes anti-cancer superfoods to help you not just lose weight but live a long, disease-free life. (P.S. Follow these guidelines to make sure you're absorbing all the nutrients from your food.)
Many diets, including Atkins and the keto diet, fit into this umbrella. A typical low-carb diet limits carbs to less than 60 g daily, but this can vary, according to the Mayo Clinic. (15) In a September 2015 review published in PLoS One, people following low-carb diets saw modest weight loss — although study authors note that long-term effects of the diet require further research. (16)
In the first week, many people report headaches, mental fogginess, dizziness, and aggravation. Most of the time, this is the result of your electrolytes being flushed out, as ketosis has a diuretic effect. Make sure you drink plenty of water and keep your sodium intake up.6One of the fathers of keto, Dr. Phinney, shows that electrolyte levels (especially sodium) can become unbalanced with low carb intake.
In the mid-1990s, Hollywood producer Jim Abrahams, whose son's severe epilepsy was effectively controlled by the diet, created the Charlie Foundation to promote it. Publicity included an appearance on NBC's Dateline programme and ...First Do No Harm (1997), a made-for-television film starring Meryl Streep. The foundation sponsored a multicentre research study, the results of which—announced in 1996—marked the beginning of renewed scientific interest in the diet.
Nuts, the second food to watch, contain a fair amount of carbohydrate, and it’s very easy to unwittingly scarf down large quantities. Cashew nuts are among the worst carb-wise – you’ll find that they contain around 20% carbohydrate by weight. For someone following a strict keto diet with a 20 grams of carbs per day allowance, this means that consuming 100 grams (which happens in a flash!) will have filled their daily quota. Peanuts tend to be around 10-15% carbohydrate – not putting them in the clear either.
There is research that supports the ketogenic diet for diabetes management, while other research seems to recommend opposing dietary treatments like a plant-based diet. Research from 2017 confirms that people with diabetes who followed a plant-based diet experienced significant improvements in blood sugars and A1c, cardiovascular disease risk factors, gut bacteria that is responsible for insulin sensitivity, and inflammatory markers like c-reactive protein.
Many CDEs actually have diabetes…it’s what draws them to choose this career…to help others with diabetes, to share their knowledge. Most already wear an insulin pump and continuous glucose sensors (CGMs) also. When I first became certified on each new pump and CGM, I would wear them (and check my BG 4-6 times per day) for 2-3 weeks, not only to learn the technology really well, but to gain a sense of how my patients must feel having to wear them 24 hours per day. Since, I’ve started a 6 month old baby on a insulin pump and CGM all the way up to a 89 year old…there are no boundaries for people with diabetes!
Cold fried chicken breast (don’t eat the skin or coating). Hint: The chicken doesn’t have to be cold. This could be a fast-food lunch but only if you can choose whole chicken parts. (Definitely do not choose chicken tenders, patties, crispy chicken, or nuggets. They have too much breading for the amount of meat.) Most fried chicken places have coleslaw as a side. When you get back to your office, you can have the carrots and Jell‑O.

Rich in low-starch vegetables, fruit, healthy fats (mostly from olives and olive oil), nuts, seeds, whole grains, legumes, and fish, the Mediterranean diet eschews simple sugars and refined starches and is low in red meat. Interested in embarking on the diet for yourself? Read through to see a Mediterranean diet shopping list, what it's like to be on the diet, and why it's so easy to follow.
What if we told you that you could make 20 percent of your belly disappear this year—poof, just gone? Penn State University researchers compared those who consumed avocado oil with those who consumed a flax-safflower oil blend. Those on the avocado oil diet—just three tablespoons daily did the trick—lost nearly 2 percent of their belly fat in just one month.

If you ate a hearty breakfast, you won’t be hungry until lunch. It’s best to brown-bag it because you can control the ingredients and portions, but if you eat out, look for grilled fish and salad as a menu option. Don’t eat at your desk while writing a report, but go to the park with a friend or join your co-workers in the lunch room. Bringing leftovers is also a good lunch option.

“Don't like eating meat?” asks Ginger Hultin, RDN, a dietitian in private practice in Seattle and a spokesperson for the Academy of Nutrition and Dietetics. “Then don't be paleo! Travel a lot and rely on eating out? The DASH diet may end in frustration for you.” The bottom line: The diet you choose needs to be safe and effective, while taking into account your lifestyle.
The Keto diet versus Plate Method study triggered some challenges and a bit of criticism. In an editorial, Andrew Reynolds, PhD, a postdoctoral research fellow at the University of Otago, New Zealand, suggests that the much better results in those on the ketogenic diet may be due not to the diet itself but to the lifestyle changes and ongoing support that keto diet group received.5
MEME WAS TALKING ABOUT DIETS. I GOT THE BOOK ON THE DASH DIET AND I RLY LIKE IT. IT'S A DIET, YEAH, BUT IT'S ALL FOCUSED ON FEEDING YOURSELF GOOD THINGS, FOCUSING ON HITTING TARGETS FOR GETTING THE NUTRITION YOU NEED (A CERTAIN AMOUNT OF SERVINGS OF VEGGIES, FRUIT, LOW-FAT DAIRY, WHOLE GRAINS, ETC.) INSTEAD OF ON CALORIES. BUT CALORIES ARE STILL PART OF THE EQUATION, SO IT'S ALL SO FUCKING REASONABLE. IL IT.
“We do not recommend the diet,” he says. “It works for weight loss, and the liver insulin resistance we observe might be transient. But the diet is simply not necessary and probably not the best choice for weight loss,” he says. “Ketogenic diets are often very low in fiber, which may have bad effects on gut health and overall health, especially over a long term. Diets high in fiber and low in fat work equally well or better than low-carb plans, in many studies, to achieve weight loss and lower glucose intolerance.”
Throughout this article, we looked at the data and the principles behind how low-carb dieting affect patients with diabetes, but we never addressed what you can do about it directly. If you’d like to learn about practical strategies that may help you reverse insulin resistance and improve your blood sugar and HbA1C levels, I recommend reading these articles:
You'll find lots of free Mediterranean diet resources on the Oldways website, including an easy-to-understand food pyramid; a printable grocery list; gender- and age-specific tips on making the Mediterranean switch; a quick-read "starter" brochure; a recipe newsletter; and even a glossary defining Mediterranean staples, from bruschetta to tapenade.
While the American Diabetes Association notes that many individuals with the disease or its precursor, prediabetes, employ carb counting to control their blood sugar on a regular basis, others have turned to ultra-low-carb diets as a way to manage their symptoms. These diets are highly restrictive and often limit followers to consuming no more than 20 grams (g) of carbs per day, usually with no added sugar, and, depending on the diet, increased protein and fat. Experts say they rarely have patients who ask about following a ketogenic diet or a modified paleo diet long term, but they can be useful for short-term weight loss if done properly.
Although some studies have indicated that a ketogenic diet is associated with dyslipidemia (cholesterol and triglyceride perturbations), many of these results were obtained from studies on rodents and did not always agree with what the data show in human studies. A recent review summarized the controversy, highlighting the discrepancies in the literature. In part, the discordance is likely due to the exact composition of the diet, specific study design, as well as the metabolic differences between rodents and humans.
“Think outside of the box when you’re preparing what to eat. I wake up every day excited to eat breakfast because I love the foods I've bought and prepared and can't wait to savor them,” Moreno says. Instead of boring oatmeal in the morning, which Moreno calls, “Oliver Twist food,” jazz it up. “Try oatmeal with vanilla protein powder, walnuts toasted in ghee, and cinnamon, that’s much more exciting.”
While body weight decreased significantly (-8.5 kg) in these 21 diabetic participants, the mean weight loss was less compared with what we observed in the LCKD participants of an earlier trial (-12.0 kg) . Given that the diabetic participants had a higher baseline mean weight than the LCKD participants of our previous trial (131 kg vs. 97 kg), this translates into an even more dramatic disparity in percent change in body weight (-6.6% vs. -12.9%). This lesser weight loss might result from several factors. First, in the current study, most of the participants were taking insulin and/or oral hypoglycemic agents that are known to induce weight gain[20,21] Second, these same agents, particularly insulin, inhibit ketosis, which is strived for in the earliest phases of the LCKD; while it remains unclear whether ketones actually play a role in weight loss on the LCKD, previous research in non-diabetic patients has shown a positive correlation between level of ketonuria and weight loss success . Lastly, compared with our previous study the participants in the current study had more comorbid illness, lower socioeconomic status, and a shorter duration of follow-up (16 weeks versus 24 weeks), all of which are associated with reduced success on any weight loss program .
Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed. Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula. Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet. KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding. Other formula products include KetoVolve and Ketonia. Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.
Advocates for the diet recommend that it be seriously considered after two medications have failed, as the chance of other drugs succeeding is only 10%. The diet can be considered earlier for some epilepsy and genetic syndromes where it has shown particular usefulness. These include Dravet syndrome, infantile spasms, myoclonic-astatic epilepsy and tuberous sclerosis complex.
Hello, I am hoping someone can reach out to me and explain something. My son who is T1D just started the keto diet 4 days ago. At first we were doing great numbers were good, then out of nowhere we are having highs! He is correcting and it’s not bringing him down into normal range. I am going into a panic, I don’t know what to do, or who to ask for help. His doctor would be no help, and thinks the Standard American Diet is fine. I don’t see eye to eye with him. I hope someone can tell me why this might be happening. Thanks in advance for your time!
This diet also works for every type of eater who wants variety in their meals. I don’t know about you, but I’ve never had Pistachio-Crusted Sole much less would I know how to make it. But in the “Mediterranean Diet Plan,” everything I need to know is on page 175 along with substitution tips in case I can’t find pistachios or want to try pecans or cashews instead. I also can see the health breakdown too. “The Mediterranean diet incorporates as lot of nuts, like walnuts, pistachios, and cashews which have a lot of fiber,” adds Zogheib. “Also tuna fish, king mackerel, salmon, all have omega 3 and omega 6 fatty acids. There’s are whole grains, bananas, and one of the best oils to bake with — canola and olive oils. You can replace fatty butter with these oils when baking.”
Our bodies are incredibly adaptive to what you put into it – when you overload it with fats and take away carbohydrates, it will begin to burn ketones as the primary energy source. Optimal ketone levels offer many health, weight loss, physical and mental performance benefits.1There are scientifically-backed studies that show the advantage of a low-carb, ketogenic diet over a low-fat diet. One meta-analysis of low-carbohydrate diets showed a large advantage in weight loss. The New England Journal of Medicine study resulted in almost double the weight loss in a long-term study on ketone inducing diets.
