Use an adult energy needs calculator to estimate your calorie intake needs; then subtract the 500 to 1,000 calories for weight loss. For example, a 28-year-old woman who is 5 foot, 9-inches tall weighs 175 pounds and is lightly active -- less than an hour a day -- burns about 2,400 calories daily. She'll burn about 2 pounds of fat in a week if she eats 1,400 calories daily, or 1 pound a week if she eats 1,900 calories a day.


With an important event coming up, you may want to get rid of your belly fat in one week. While it's impossible to lose a lot of fat in just one week, you can lose water weight, which will reduce bloating and the appearance of fat in your belly. Long-term fat loss requires a commitment, but if you need a short-term solution, be strict in your diet and exercise to reach your goals.
Whether you're headed to the beach, prepping for a special occasion or just want to jump-start a healthier lifestyle, you can set the foundation for belly fat loss in a week. And while you likely won't reach your final weight loss goals in a week -- unless you're only looking to lose a pound or two -- you might be able to see minor differences and burn some initial belly fat. However, the results from diet and exercise modifications can keep you motivated to stick to longer term goals, and they'll set you on a road to success -- without the high risk of weight regain associated with fad crash diets.
This naturally sweet winter squash boasts one of the highest fiber counts of all the veggies, ringing in at a whopping 9 grams per cup. Promoting feelings of fullness—and thus staving off overeating so you can burn, rather than gain, fat—with satiating fiber isn’t the only way you’ll target that turkey neck. That’s because acorn squash is also an excellent source of vitamin C, a micronutrient that your body uses to decrease levels of the fat-storing hormone cortisol and boost the fat-burning effects of exercise, according to Arizona State University researchers.
Some cheat meals are better than others. And a high-carbohydrate, moderate-protein meal, however “naughty,” can help you stay on track. The reason: Carbohydrates have the greatest influence on leptin levels, which help you burn fat and feel satisfied. And protein has the greatest influence on satiety because of its influence on appetite-regulating hormones and high thermic effect—the process of digesting protein requires more energy of your body than any other macronutrient. So, go ahead and grab a bowl of spaghetti and meatballs. Contrary to popular belief, pasta is actually a fairly low-glycemic food, meaning it won’t drastically spike your blood sugar levels.
A scoop of guacamole is one of the most effective fat-burning, hunger-squashing snacks known to man. Not only are avocados rich in vitamin B6—which directly counteracts the belly-fat-building stress hormone, cortisol—they’re also full of monounsaturated fat. This healthy fat may actually prevent body fat distribution around the belly by down-regulating the expression of certain fat genes, according to research in the journal Diabetes Care. These same satiating fats may also be the reason behind another study that found people who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterward.
That’s because women tend to store more temporary fat in their bellies. “The fat stores are gained and lost,” says Lawrence Cheskin, MD, chair of the department of nutrition and food studies at George Mason University and director of the Johns Hopkins Weight Management Center. “By and large, belly fat comes off easier in the sense that it comes off first. That’s where a good amount of the fat is lost from.”

Each slice of grapefruit you add to your salad acts like a match to spark your body’s fat-burning ability. A study published in the journal Metabolism found that those who ate grapefruit for six weeks lost a full inch off their waistlines. What’s behind the belt-tightening effect? The fruit is rich in phytochemicals, bioactive compounds that recent research shows stimulate the production of a hormone called adiponectin, which is involved in the breakdown of body fat. Japanese research suggests the smell of the juicy fruit can “turn on” calorie-burning brown fat cells, promoting the breakdown of body fat while reducing appetite.


Whether it’s turning off fat genes, helping to build muscle that robs energy from adipose cells, revving your metabolism and ability to burn fat, or helping you feel fuller longer so you consume fewer calories, these foods have been proven to show an increased rate of fat loss. So stop these bad habits that give you belly fat, and instead, incorporate these healthy fat burning foods into your diet to whittle your waist and bring your midriff back in line.

If you’re only getting a minimal amount of sleep each night, that leaves more time for you to snack and make otherwise unhealthy decisions that could affect your weight loss. Although it will vary from person to person on how much sleep you actually need to be most effective (and therefore make progress toward your weight loss goals), the ideal number is typically 7 or 8 hours, says Dr. Cheskin. (Struggling to get that shut-eye? This doctor-approved breathing exercise will help you fall asleep fast.)
