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.
There’s a reason everyone harps on about protein: Not only does it help keep you full, but it’s also responsible for repairing the tiny tears caused by strength training in your muscles. This helps them grow bigger and stronger, nudging out body fat in the process. As a general rule of thumb, aim to get at least 70 grams of protein throughout the day, says Dr. Cheskin. (These high-protein foods can help you reach that goal.)
Want a flatter stomach? Look in your glass—milk and soda are two major causes of tummy inflation. Approximately 65 percent of the human population has a reduced ability to digest lactose after infancy, which means that your glass of warm milk before bed may be the reason you wake up with too-tight pajamas. And when it comes to soda, both regular and diet are belly busters both from the sweeteners used and the carbonation. Try eliminating these from your diet and see if it helps flatten your tummy.
As we mentioned above, eating in a calorie deficit is key. Jim recommends eating 500 calories less than your total daily energy expenditure, or TDEE. This is the number of calories you burn in a day, which is based on factors like age, height, sex, and activity level. To calculate what this number is and what your calorie target should be to lose weight, use this formula. Just make sure you don't go below 1,200 calories a day for women; in a previous interview, Jim said eating any fewer calories than that can slow down your metabolism and result in negative side effects like low energy, loss of hair, hunger pangs, and a negative impact on your menstrual cycle.
If you haven't been able to lose your belly fat on your own, we've asked experts to share the tips and advice they use with clients to help them lose belly fat for good. Vermont-based registered dietitian and nutritionist Maddie Kinzly, MS, LD, told POPSUGAR that while you can't choose where on your body you gain or lose fat (sorry, boobs!), some people are more predisposed to holding weight in their bellies.
Eat More Produce. Eating lots of low-calorie, high-volume fruits and vegetables crowds out other foods that are higher in fat and calories. Move the meat off the center of your plate and pile on the vegetables. Or try starting lunch or dinner with a vegetable salad or bowl of broth-based soup, suggests Barbara Rolls, PhD, author of The Volumetrics Eating Plan. The U.S. government's 2005 Dietary Guidelines suggest that adults get 7-13 cups of produce daily. Ward says that's not really so difficult: "Stock your kitchen with plenty of fruits and vegetables and at every meal and snack, include a few servings," she says. "Your diet will be enriched with vitamins, minerals, phytonutrients, fiber, and if you fill up on super-nutritious produce, you won't be reaching for the cookie jar."
