Also worth noting is that low-carbohydrate, low-GI, and Mediterranean diets led to significant improvements in blood lipids with up to a 4–10% increase in HDL (4% in the Mediterranean, 5% in low-GI, and 10% in low-carbohydrate diets), 1–4% reduction in LDL (1% in low-carbohydrate, 3% in low-GI, and 4% in Mediterranean diets), and 9% reduction in triglycerides. 
A small Feb. 20, 2017, study looked at the impact of a six-week ketogenic diet on physical fitness and body composition in 42 healthy adults. The study, published in the journal Nutrition & Metabolism, found a mildly negative impact on physical performance in terms of endurance capacity, peak power and faster exhaustion. Overall, researchers concluded, “Our findings lead us to assume that a [ketogenic diet] does not impact physical fitness in a clinically relevant manner that would impair activities of daily living and aerobic training.” The “significant” weight loss of about 4.4 pounds, on average, did not affect muscle mass or function.
Coffee jumpstarts your metabolism, making the non-decaf stuff a worthy weight loss ally. According to a study published in the journal Physiology & Behavior, the average metabolic rate of people who drank caffeinated coffee was 16 percent higher than that of those who drank decaf. In addition to caffeinating your coffee, it’s also crucial to keep it black and avoid adding any unhealthy creamers and artificial sweeteners, both of which are enemies of weight loss.
Speaking of standout breakfast foods, Greek yogurt is another option worthy of the spotlight thanks to its high-protein content. Per study in the journal Appetite, researchers from the University of Missouri compared the satiety effects of high-, moderate-, and low-protein yogurts on women aged 24-28, and found Greek yogurt, with the highest protein content, to have the greatest effect. What’s more? Probiotics in items such as yogurt and fermented foods, like pickles and sauerkraut, help good bacteria in the gut process food more efficiently. Hello, weight loss! If you want to get even more protein in your yogurt, check out Icelandic yogurts, which can have two to three more grams of protein per serving compared to Greek.
This book has helped me tremendously! My doctor recommended the Dash Diet for my high blood pressure. I have to say, it was not easy to break my addiction to sugar. Phase one (2 weeks) is painful. I failed a few times before finally breaking through and sticking with it. I had SO much success on phase one, I was afraid to move on and reintroduce fruit and whole grains to my diet so I remained on it for another 2 weeks. In one month of following the diet closely I lost almost 20 pounds. My blood pressure dropped so dramatically that my medication had to be significantly decreased. I did not do the exercise as recommended in the book due to very low energy levels, but imagine that if I had, I would have lost more weight. I highly recommend this book to anyone who has high blood pressure or cholesterol and wants to lose weight.
Earlier this month during a taping of HeartTalk presented by Capital Cardiology Associates, Dr. James O’Brien mentioned the Mediterranean diet. He said it was a diet that he strongly recommend for patients with heart disease. Now, being a health and fitness enthusiast and a 40-year old man with a family history of diabetes and heart disease, I am always open to ways to improve my heart health.
And while the diet wasn't designed with weight loss as a primary goal, it's no secret that many of the nutritional factors that influence blood pressure also influence weight, she says. Think: processed foods, trans fats, and excess sugar. According to one DASH study, adults who who followed the diet lost more weight in a span of eight to 24 weeks than those adhering to other low-calorie diets.

“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.”
“During physiological ketosis ketonemia reaches maximum levels of 7/8 mmol/L with no change in pH while in uncontrolled diabetic ketoacidosis it can exceed 20 mmol/L with a concomitant lowering of blood pH. Blood levels of ketone bodies in healthy people do not exceed 8 mmol/L precisely because the central nervous system (CNS) efficiently uses these molecules for energy in place of glucose,” researchers summarize.
Con: Results can vary depending on how much fluid you drink. By drinking more water, you dilute the concentration of ketones in the urine and thus a lower level of ketones will be detected on the strips. The strips don’t show a precise ketone level. Finally, and most importantly, as you become increasingly keto-adapted and your body reabsorbs ketones from the urine, urine strips may become unreliable, even if you’re in ketosis.
