Studies show that eating breakfast plays a part in successful weight loss — almost 80 percent of people who successfully keep weight off chow down on this meal, according to a study published in Obesity Research. "Your metabolism slows as you sleep, and the process of digesting food revs it up again," explains Heller. Aim for a 300- to 400-calorie breakfast, such as a high-fiber cereal (another metabolism booster) with skim milk and fruit.
It is best to eat a strict Bulletproof Diet for at least a week or two beforehand to store extra nutrients. This also helps reset your hormonal status if you’ve been yo-yo dieting. You don’t have to do this, but it’s a good idea. You may find that eating The Bulletproof Diet is enough of a stimulus for weight loss, and that fasting is unnecessary. You also need to get used to digesting fat if you’ve been on a low-fat diet.
This formula will help you lose weight faster, says Kristin Kirkpatrick, R.D., manager of wellness nutrition services at the Cleveland Clinic Wellness Institute. A 2016 study published in the American Journal of Clinical Nutrition suggests that increasing your protein intake while decreasing the amount of calories you consume ensures that you lose fat instead of muscle. This 35-35-30 breakdown doesn't mean you can eat any old carb or fat though, she says. Aim to get most of your healthy fat from nuts and fish, your carbs from beans and whole grains, and protein from lean sources like eggs, chicken, and fish, she says.
Muscle tissue is a biologically active tissue, this means that it needs and uses calories just to continue being. Some studies have shown that 1 pound of muscle can burn up to 50 calories per day by simply existing. This means that if you gain 10 lbs of muscle you can eat 500 more calories per day and still lose fat. This is just one of many reasons why it is so important to preserve muscle tissue while cutting fat.
High-intensity interval training—HIIT—has gained a reputation as an efficient way to get fast results. This workout involves short (30 seconds to five minutes), vigorous bursts of activity interspersed with periods of rest for maximum results. Incorporating HIIT into your strength training may offer even more results, according to a recent study by the American Council on Exercise—the results suggest the combo may be even more effective in burning fat fast.
This may explain why the fat-burning effects of eating more protein were confirmed in a study published in the American Journal of Physiology. One group was fed a high-protein diet (just over 1 gram per pound of body weight per day) while the second group consumed an amount closer to the lower recommendation of the RDA (recommended dietary allowance). The group eating the higher-protein diet burned the most fat.
