A diet that’s low in fat and carbohydrates can improve artery function, according to a 2012 study by Johns Hopkins researchers. After six months, those on the low-carb diet had lost more weight, and at a faster pace. But in both groups, when weight was lost—and especially when belly fat shrank—the arteries were able to expand better, allowing blood to travel more freely. The study shows that you don’t have to cut out all dietary fat to shrink belly fat. For heart health, simply losing weight and exercising seems to be key.

This two-week program mandates the use of heavy compound exercises to start every weight workout. By keeping heavy training in your program, you’ll force your body to keep its natural production of growth hormone (GH). High GH, which peaks while you sleep, is a key player in the fat-burning process. Then, by targeting individual body parts with Tabata-style work, you’ll increase local blood flow to working muscles. On each Tabata exercise, start with a weight you can handle for 12–15 reps. As the work drags on, your rep counts will fade. Pause only when needed, and perform partial reps if necessary to keep going the entire 20 seconds.
At any given time, there are dozens of weight-loss hypes in the marketplace that claim to take off 10 pounds in 10 days, or whatever. Desperation can tempt us to try anything — from "clean eating" to cutting out food groups entirely. Keep in mind: Just because an avocado-kale-salad dripping in coconut oil is deemed "clean" by a so-called "expert" on your Instagram feed does not make it an unlimited food. Moral of the story? Avoid fads, eat real food, watch some Netflix, and unwind (perhaps with a glass of wine in hand). Now that's my kind of detox.
Whether or not you’re specifically aiming to cut carbs, most of us consume unhealthy amounts of sugar and refined carbohydrates such as white bread, pizza dough, pasta, pastries, white flour, white rice, and sweetened breakfast cereals. Replacing refined carbs with their whole-grain counterparts and eliminating candy and desserts is only part of the solution, though. Sugar is hidden in foods as diverse as canned soups and vegetables, pasta sauce, margarine, and many reduced fat foods. Since your body gets all it needs from sugar naturally occurring in food, all this added sugar amounts to nothing but a lot of empty calories and unhealthy spikes in your blood glucose.
For example, a 200-pound guy following this program would consume 200 grams of protein per day, and eat 2,000–2,200 calories—that’s approximately 420 calories (about 50 grams) from fat, and 880 calories (220 grams) from carbs. Your protein and fat intake will stay relatively constant, but your carbs can be raised or lowered as needed (see Step 5). So, if you’re taking your shirt off on Saturday, begin following this protocol the Saturday prior.
A 2012 study also showed that people on a low-carb diet burned 300 more calories a day – while resting! According to one of the Harvard professors behind the study this advantage “would equal the number of calories typically burned in an hour of moderate-intensity physical activity”. Imagine that: an entire bonus hour of exercise every day, without actually exercising. A later, even larger and more carefully conducted study confirmed the effect, with different groups of people on low-carb diets burning an average of between 200 and almost 500 extra calories per day.
Testing your limits brings about than just bragging rights. Lifting a heavier weight for fewer reps burns nearly twice as many calories during the two hours after your workout than lifting a lighter weight for more reps, according to research published in the journal Medicine & Science in Sports & Exercise. Feel smug in the knowledge you’re still torching calories in that 10am meeting.
Want to lose that belly fat fast? In your dreams! Seriously, though: a good night’s sleep is one of the best ways to get rid of that extra fat around your waist for good. Among the 60,000 women participating in the Nurses’ Health Study, those who snoozed for fewer than five hours a night were at the greatest risk of becoming obese and gaining 30 or more pounds over the course of the 16-year study period when compared to those who slept for seven or more hours.
Too little sleep or too much sleep can throw your stress and regulatory hormones out of whack, and may lead to weight gain. A single night of sleep deprivation can increase levels of ghrelin (a hormone that promotes hunger), making you more likely to overeat the next day. Reduced sleep may also lead to fatigue during the day (duh) and less physical activity, which may be another reason why people who regularly don't get enough sleep tend to gain weight.
On the Shred Diet, you’ll eat four meals and up to three snacks a day. Eating smaller meals will keep you from getting hungry as you distribute your calories throughout the day. Equally important, spacing out your meals will keep your hormones stable. When you eat small meals, especially meals composed of foods that have a low-glycemic index (choices that are less likely to spike your blood sugar), you prevent surges in hormones that lead to weight gain.
In fact, a study published in 2016 in the International Journal of Obesity looked at the metabolic health markers of more than 40,0000 adults and found that nearly half of people who are overweight, and 29 percent of people classified as having obesity, were cardiometabolically healthy. It also found that more than 30 percent of people at so-called “healthy weights” had poor cardiometabolic health—which can include hypertension, high cholesterol, inflammation, and insulin resistance.
Here's something else most people probably don't know: Fidgeting is good for you. It's considered a nonexercise physical activity, and it's an important way to burn energy. You get more health benefits if, in addition to exercising, you are a more fidgety, more active person the rest of the day. This means gesturing while you're talking, tapping your foot, just moving around.
