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.”
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.
Ultimately, you need to pick a healthy eating plan you can stick to, Stewart says. The benefit of a low-carb approach is that it simply involves learning better food choices—no calorie-counting is necessary. In general, a low-carb way of eating shifts your intake away from problem foods—those high in carbs and sugar and without much fiber, like bread, bagels and sodas—and toward high-fiber or high-protein choices, like vegetables, beans and healthy meats.
Like protein, fiber slows the rate at which your body plows through carb calories so you feel full for longer and maintain steadier blood sugar levels, one reason why research consistently links fiber intake to weight loss. That means fibrous whole grain bread tends to be a better choice than white bread and also explains why fruits, which contain fiber and valuable vitamins in addition to sugar, beat straight-up candy every time.
Sorry keto -- the Mediterranean diet is king. Endurance athletes and celebrities like LeBron James and the Kardashians have raved about the high-fat, low-carb ketogenic diet -- which was among Google’s most-searched terms this year. But Dr. Louis Aronne, an endocrinologist at NewYork-Presbyterian and Weill Cornell Medicine who runs the Comprehensive Weight Control Center, noted that the Mediterranean diet “is the only diet that has been proven in trials to promote weight loss and reduce the risk of heart attack, stroke and other cardiovascular diseases.” This meal plan includes using olive oil rich in healthy omega-3 fatty acids as your main cooking oil, and loading your plate with fruits and vegetables, whole grains and lean protein like fish and chicken, with the occasional piece of red meat. The American Heart Association recommends a similar diet that emphasizes whole, unprocessed foods, particularly fruits, veggies and whole grains, as well as low-fat dairy products, nuts and legumes, and non-tropical vegetable oils, while reducing salt, sugar and trans fats.
Fiber is a type of carbohydrate that your body can't digest, and it helps regulate the body's use of sugar as it slowly passes through your digestive system. Increasing your daily fiber intake can result in greater satisfaction after meals, less blood-sugar spiking and crashing, and subsequent reductions in the amount of calories eaten for the rest of the day. When trying to trim belly fat, aim to get at least 25 grams of fiber in your diet each day. Foods that are rich in fiber include pulses, like lentils and beans; apples and pears, with the skin; nuts and seeds; and cruciferous vegetables like broccoli and Brussels sprouts.

Choose Liquid Calories Wisely. Sweetened drinks pile on the calories, but don't reduce hunger like solid foods do. Satisfy your thirst with water, sparkling water with citrus, skim or low-fat milk, or small portions of 100% fruit juice. Try a glass of nutritious and low-calorie vegetable juice to hold you over if you get hungry between meals. Be careful of alcohol calories, which add up quickly. If you tend to drink a glass or two of wine or a cocktail on most days, limiting alcohol to the weekends can be a huge calorie saver.
