From intermittent fasting to the keto diet to teatoxes, there's a plethora of diet advice out there. Maybe the keto diet worked wonders for your co-worker, but it’s just not conducive to your nutritional needs. Or not eating after 7 p.m. helped your sister lose 20 pounds, but you like doing evening workouts. The truth is losing weight is hard—and it takes patience—so if it's too good to be true, then it probably is. “Adopting healthy habits is not easy, but most things in life that are worthwhile take work,” explains Bonnie Taub-Dix, RDN and author of Read it Before You Eat It - Taking You from Label to Table. But losing weight doesn't need to be complicated. Following these simple nutritionist-backed tips will help point you in the right direction and reach your goals.
A study published in the journal Nutrition & Metabolism discouraged the Atkins diet for anyone with diabetes because the plan doesn’t limit fat, but noted the approach may be a safe way for people without the disease to lose weight effectively. According to a study published in the Journal of the American Medical Association, Dr. Atkins helped women lose weight better than other low-carb diets, such as the Zone diet, the Ornish diet, and the LEARN diet after 12 months.
While there isn't "a" Mediterranean diet, most versions share many of the same principles. According to Oldways, the nonprofit food think tank in Boston that helped develop a Mediterranean food pyramid, you'll load up on fruits, veggies, whole grains, nuts and legumes; eat plenty of fish and seafood; get a little poultry, eggs, cheese and yogurt; and mostly pick at sweets and red meat. And don't forget a drizzle of olive oil and (if you want) a couple glugs of wine.
That makes a lot of sense. Keeping up insulin pathways when you aren’t eating carbs would be like keeping the lights on when it’s daytime outside — it’s a waste of energy. You aren’t using insulin on keto, so your body probably downregulates your insulin pathways. As a refresher, insulin is a hormone produced by your pancreas that tells your cells to absorb glucose to use as fuel. When you eat carbs, insulin production begins. In the absence of carbs, there’s less need for insulin.
In recent years, the ketogenic diet has been attracting a lot of attention for the management of numerous health conditions, as well as for weight loss. Some controversy still exists about its safety and efficacy, largely stemming from a lack of longitudinal and mechanistic studies, inconsistencies in diet composition in different cohorts, and disagreement in conclusions between research conducted on animal vs. human populations.
The trick here is not only to avoid all obvious sources of carbohydrate (sweets, bread, spaghetti, rice, potatoes), but also to be careful with your protein intake. If you eat large amounts of meat, eggs and the like, the excess protein will be converted into glucose in your body. Large amounts of protein can also raise your insulin levels somewhat. This compromises optimal ketosis.
What the expert says: ‘Over 50 years ago researchers realised they didn’t have to restrict energy every day and they still got a protective effect. In animals, these diets were shown to reduce visceral fat, oxidative stress and reduce cell proliferation, which is involved with the development of cancer. The models that were used in humans were two consecutive days of 650kcal then five days following a normal, healthy diet, versus a healthy med diet of 1500kcal.
Upon starting the diet, some patients report symptoms like fatigue, headaches, and muscle aches. However, these short-lived symptoms are, in fact, a sign that the diet is working, and the body is switching over from burning glucose as fuel to burning fat. This transition involves upregulating certain enzymes and down-regulating others; it is a profound shift for the human body that can have uncomfortable symptoms. However, these side effect usually last only 3-4 weeks. They can be ameliorated in most cases, by drinking several cups of bouillion broth during the day until the transition is completed.15
The low glycaemic index treatment (LGIT) is an attempt to achieve the stable blood glucose levels seen in children on the classic ketogenic diet while using a much less restrictive regimen. The hypothesis is that stable blood glucose may be one of the mechanisms of action involved in the ketogenic diet, which occurs because the absorption of the limited carbohydrates is slowed by the high fat content. Although it is also a high-fat diet (with approximately 60% calories from fat), the LGIT allows more carbohydrate than either the classic ketogenic diet or the modified Atkins diet, approximately 40–60 g per day. However, the types of carbohydrates consumed are restricted to those that have a glycaemic index lower than 50. Like the modified Atkins diet, the LGIT is initiated and maintained at outpatient clinics and does not require precise weighing of food or intensive dietitian support. Both are offered at most centres that run ketogenic diet programmes, and in some centres they are often the primary dietary therapy for adolescents.
On a ketogenic diet, your entire body switches its fuel supply to run mostly on fat, burning fat 24-7. When insulin levels become very low, fat burning can increase dramatically. It becomes easier to access your fat stores to burn them off. This is great if you’re trying to lose weight, but there are also other less obvious benefits, such as less hunger and a steady supply of energy. This may help keep you alert and focused.
