It’s possible you’ve lost significant fat already with foods like milk, wheat bread, and artificial sweeteners in your diet, but for the next week, cut these out entirely—even if you don’t think you have an intolerance to them. Even the slightest irritation to your digestive system can cause bloating and water retention, so eliminate the risk completely. Dairy and gluten appear in numerous condiments (soy sauce, salad dressings, some brands of barbecue sauce, etc.), so to avoid a potential problem, read labels and control your intake as much as possible. Season your food with condiments such as sea salt, salsa, and balsamic vinegar instead.
Successfully flattening your stomach is a matter of burning body fat and building muscle. The best way to burn body fat is through cardio exercises such as running, walking, elliptical training, and bicycling. With these exercises, burning stomach fat, shedding love handles, and building a six pack is completely do-able. So send your body the memo: flat abs are in style and it’s time to get yours!
You’re only losing one or two pounds a week. Sustainable weight loss is slow and steady. “It depends on where you start — if you have quite a bit of weight to lose, you tend to lose the initial weight faster,” noted Dr. Steinbaum, “but losing more than a pound a week is quite a bit. A gradual decrease in weight loss implies that your dietary changes are sustainable. If you lose weight very quickly, it means that there has been a calorie restriction or an increase in activity that is really significant, and it is really hard to sustain that.” That’s why so many yo-yo dieters gain the weight back. But aiming for smaller targets can add up to big changes -- and reaps more health benefits than the numbers on the scale suggest. “Even when you lose only 3% of your body weight (six pounds for a 200-pound person), your blood sugar improves; your insulin sensitivity is improved; inflammation goes down; your cholesterol goes down,” said Dr. Arad. “You don’t have to cut down half of your weight; even losing 3% to 5% is an excellent goal.”
Remember that it takes a 3500-calorie deficit to lose one pound of fat. That is, you have to either burn off 3500 calories through exercise or eat 3500 calories less than you burn in a week. Break this up into daily limits. To burn 3500 calories a week, you should aim to have a 500 calorie deficit every day. For example, you can exercise to burn 250 calories and cut 250 calories from your diet.
Jim said people can healthily lose half a pound to two pounds a week. In a month, that could add up to four to eight pounds lost. Since one pound of fat equals 3,500 calories, to lose one pound a week, you would have to burn approximately 500 extra calories a day. This can be achieved through eating in a healthy calorie deficit or working out to burn extra calories (or a combination of both). Other lifestyle factors also play a role. Getting enough sleep will ensure your body recovers well and that you'll be energized for your workouts the next day. And too much stress increases the stress hormone cortisol, which can increase your cravings for caloric refined carbs and comfort food, which will prevent you from losing weight (especially in your belly). Make sure, in addition to eating in a calorie deficit, that you're also getting at least seven hours of sleep a night and managing your stress.
Sure, you can lose weight quickly. There are plenty of fad diets that work to shed pounds rapidly -- while leaving you feeling hungry and deprived. But what good is losing weight only to regain it? To keep pounds off permanently, it's best to lose weight slowly. And many experts say you can do that without going on a "diet." Instead, the key is making simple tweaks to your lifestyle.
