Cut back on carbs: Remember how insulin has the biggest impact on fat storage? Well, carbs have the biggest impact on insulin. ”Too many carbohydrates leads to a spike in the hormone and then to more fat storage,” Seedman explains. Not only should you cut back on carbs, but your insulin will spike even more from processed ones, so cut any carb that’s not a whole grain or from real produce completely. And don’t worry: Carbs are traditionally thought of as your body’s main source of energy, but your body also has the ability to fuel from fat, so if you’re increasing your fat and protein intake, your body doesn’t need as many carbs to run. You still need some amount of carbohydrates to regulate certain biological processes, like your muscles’ ability to stay hydrated and maintain structural integrity, so don’t cut the macronutrient completely, Seedman warns. For a high-fat, low-carb diet, aim for at least .5 of your bodyweight (so a 200 lb person would eat at least 100 grams of carbs per day), he suggests. For a more balanced calorie-restricted diet, that number jumps to .75 to 1.5 grams per pound of bodyweight.
Do this: Eat 6-8 small meals per day, spaced 2-3 hours apart. Don't go longer than three hours without eating—your body will go into starvation mode, which can cause you to store body fat and make it more likely that you'll overeat at your next meal. Speaking of overeating, just because you're consuming more meals doesn't mean you should take in more total calories. Determine your ideal daily caloric intake for fat-burning (see Rule 1) and divide that more or less evenly between your 6-8 meals.
GH not only increases fat-burning but is required to build mass and strengthen the immune system. Yet carbs put a damper on GH release, so it's ideal to go to bed under one of two scenarios: on an empty stomach, or, even better, having consumed only protein, no carbs. This allows blood glucose—the high-tech name for digested carbs circulating in the blood—to remain low, which facilitates the rise in nocturnal GH production.
"When going out for fast food, I used to get the large-size value meal. Now, I satisfy a craving by ordering just one item: a small order of fries or a six-piece box of chicken nuggets. So far, I've shaved off 16 pounds in seven weeks, and I'm on track to being thinner than my high school self for my 10-year reunion later this year." —Miranda Jarrell, Birmingham, AL
When you’re cutting calories, it can be tough to make sure you’re still getting enough of all the good stuff your body runs on. “Nutrient deficiencies can stall or halt weight loss,” says Crandall. She sees lots of patients with low levels of vitamin D, for example, a nutrient that is critical to parathyroid hormone function—it helps with weight regulation. If you’re not eating a well-balanced diet, a multivitamin can be a good way to bridge those nutritional gaps and make sure you’re not missing anything that could impede weight loss or muscle building, such as calcium or iron.
When Johns Hopkins researchers compared the effects on the heart of losing weight through a low-carbohydrate diet versus a low-fat diet for six months—each containing the same amount of calories—those on a low-carb diet lost an average of 10 pounds more than those on a low-fat diet—28.9 pounds versus 18.7 pounds. An extra benefit of the low-carb diet is that it produced a higher quality of weight loss, Stewart says. With weight loss, fat is reduced, but there is also often a loss of lean tissue (muscle), which is not desirable. On both diets, there was a loss of about 2 to 3 pounds of good lean tissue along with the fat, which means that the fat loss percentage was much higher on the low-carb diet.
I built this protocol for people who simply won’t take my advice to be patient and eat the Bulletproof Diet while using Bulletproof Intermittent Fasting. It uses biohacking techniques I pioneered on myself to reduce – but not eliminate – the risks of rapid fat loss. It prevents the metabolic harm and brain fog that come with very low-calorie diets (or multiple day fasts), and it does everything I can think of to maintain health in the face of additional toxins.  This is also not intended for people who are already fairly lean (10-14% body fat).  It is designed for obese and severely overweight people who want to lose fat as fast as possible.
So how does this work? A quick run-through: The first tip was to eat low carb. This is because a low-carb diet lowers your levels of the fat-storing hormone insulin, allowing your fat deposits to shrink and release their stored energy. This tends to cause you to want to consume fewer calories than you expend – without hunger – and lose weight. Several of the tips mentioned above are about fine-tuning your diet to better this effect.
With potatoes, leave the skin on (with baked or mashed potatoes) or if you peel them, make snacks of them. For example, drizzle olive oil, rosemary, salt, and garlic on the peels and bake at 400 F (205 C) for fifteen minutes for baked Parmesan garlic peels. Keeping the skin on potatoes when cooking them helps keep more vitamins/minerals in the flesh (just don't eat any parts of skin that are green).
If you want to shrink your gut, get enough protein in your diet. In this case, about 25 percent of calories. Why? For starters, protein makes you feel full and helps you build muscle (which increases metabolism, thereby making it easier to lose weight). Just as important, high-protein diets have been shown to be the best way of attacking belly fat. In one study, published in the International Journal of Obesity, Danish researchers put 65 people on either a 12 percent protein diet or a 25 percent protein diet. The low-protein dieters lost an average of 11 pounds, which isn't bad. But the high-protein subjects lost an average of 20 pounds--including twice as much abdominal fat as the low-protein group.
Carbohydrates are essential to keeping a fast metabolism. Leptin and other fat burning hormones are directly related to carbohydrate intake and body fat levels. Leptin is a fat burning hormone that serves many functions. One of the most important functions is the control of energy expenditure. When food intake, and most notably carb intake is high, leptin levels will be high. This sends signals to you body that it is in a fed state and this can cause your metabolism to remain high.
The final possible culprit behind stubborn weight issues may be the stress hormone, cortisol. Too much cortisol will increase hunger levels, bringing along subsequent weight gain. The most common cause of elevated cortisol is chronic stress and lack of sleep (see tip #10), or cortisone medication (tip #9). It’s a good idea to try your best to do something about this.

While it’s often assumed that bread is off-limits when you’re trying to lose belly fat, the right bread may actually expedite the process. Switching to sprouted bread can help out carb-lovers eager to get their fix without going up a belt size, thanks to the inulin content of sprouted grains. The results of a study published in Nutrition & Metabolism reveal that found that pre-diabetic study subjects whose diets were supplemented with inulin shaved off more belly fat and total weight than those whose meal plans didn’t pack this healthy prebiotic fiber.


Have you ever decided to skip a meal to cut back on your daily calorie count? Despite saving a few calories in the moment, this strategy almost always backfires. When you skip breakfast, or any meal, you'll begin to experience excessive hunger that can lead to craving unhealthy foods—and lots of them. You may also eat faster than you normally do after skipping a meal, causing you to miss the warning signs that you're full and resulting in overeating.
With the body not able to use carbohydrates for energy it will begin producing ketones. Ketones are a by-product of fat oxidation and can be used as an energy source instead of carbs. With less carbs coming in insulin levels will be lower which leads to a greater rate of fat burning. As we now know, lower insulin levels are not always a good thing though.

Meal prepping takes a few hours a week, but it's worth it: By getting your meals ready ahead of time, you won't be so tempted to order your go-to Chinese takeout when you're tired and hungry after work. "When you plan an entire week of dinner in advance, you're way less likely to go off course and indulge in foods that aren't good for you," says Pamela Salzman, a certified holistic health expert and cooking instructor. And since you planned things out, you'll actually get the protein, fruit, and veggies your body needs — and you'll lose weight in the process.
At its core, burning fat comes down to the process of lipolysis—the breaking down of fat lipids, explains Seedman. This happens in the mitochondria of the muscles, or the powerhouses of the cells, responsible for generating the energy our cells need to do their jobs. Exercise has been shown to improve mitochondria function, which then promotes fat breakdown, Seedman adds. Plus, working out helps regulate pretty much all the hormones that optimize fat loss.
