Cyclical keto diet: The Bulletproof Diet falls into this category. You eat high fat, low carb (less than 50 grams of net carbs a day) five to six days of the week. On day seven, you up your carb intake to roughly 150 grams, during what’s called a carb refeed day. Carb cycling this way helps you avoid the negative effects some people experience when they restrict carbs long term, like thyroid issues, fatigue and dry eyes. Learn more here about how carb cycling works.
Beans can help boost feelings of fullness and manage blood sugar levels, making them an excellent ally in your weight loss battle. In fact, a recent study published in The American Journal of Clinical Nutrition found eating one serving a day of beans, peas, chickpeas or lentils could contribute to modest weight loss. And if you need another reason to bulk up on beans, remember that the fiber and protein-rich legumes are other excellent sources of genistein—the same compound found in peanuts and lentils that aids weight loss.
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.

A ketogenic diet is high in fat and low in carbohydrates. It’s called “ketogenic” because people on this diet shift from using glucose (a type of sugar) as their main fuel source to ketone bodies, which are derived from fat. In other words, people on the ketogenic diet can use their bodies’ fat stores as fuel—and this is why many studies show that this diet is superior for sustainable weight loss.
After 32 weeks, those in the keto diet group lowered their HbA1c more than those in the plate group with more than 50% achieving a reduction to less than 6.5%, basically reversing their diabetes. None in the plate group did this well. As for weight loss, those in the keto low-carb group lost on average of 28 pounds, while those in the plate group lost an average of 6.6 pounds.1
You should then transition to a normalized set of macros. While keto dieting can be good for short term fat loss, it’s important that it not brainwash you into thinking that certain foods or macros are “bad”. Eating a balanced diet with an understanding of your total daily energy expenditure (TDEE) is the healthiest way to eat and the most sustainable way to lose weight long term.
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.
