Food that burn belly fat

There is a lot of buzz surrounding foods that burn fat, but in actuality the concept has been melded into something rather misleading. There are only a handful of foods that eating them potentially increases the the immediate biochemical act of burning fat (hot peppers and green tea are two that come to mind). Most foods set you up to burn more fat if you eat them compared to if you ate something else.

Let’s take broccoli for example. Eating broccoli doesn’t stimulate the process stored fat being liberated and burned. But eating broccoli instead of bread or other high glycemic foods will result in a favorable biochemical response from your body leading to fat burning that wouldn’t have occurred with the high glycemic foods.
These are the kinds of effects that interest me. What are the changes going on in your body when you choose certain carbohydrates over others. Naked Nutrition Insiders that have watched this month’s online seminar, Glycemic Index: The Carbohydrate Solution that Works, know about the advantages to using a lower glycemic index diet approach for weight loss and health; but yesterday I came across new data showing how a low glycemic approach will allow you to keep you metabolism up almost 6% higher than your friend who is sucking on rice cakes and grape-nuts (two high glycemic foods) when trying to lose weight.

Examples Low Glycemic Foods (from Glycemic Index Online Seminar)
Researchers from Harvard (now the lead researcher is acutally at Tufts I believe) decided to look at the effects of eating a low glycemic diet on metabolic rate compared to a high glycemic index diet. They put together a small study (only 10 people) where the people were given instructions to eat a low calorie low glycemic index diet 9 days and then switch to a low calorie high glycemic index diet for 9 days (or visa versa).
Not surprising the resting energy expenditure (basically how many calories they would have burned if they laid around all day) of the participants decreased on both diets. This was expected as reducing the amount of calories you eat and not adding resistance/metabolic exercise is a sure fire way to decrease your metabolism. But, the interesting part is that the researchers reported that by the 6th day the…
resting energy expenditure declined by 10.5% during the high-GI diet but by only 4.6% during the low-GI diet.

They ate the same amount of calories. Both diets would be considered ‘healthy’ by man people (the High GI diet wasn’t loaded with sugar or anything). But the metabolic response was different. Isn’t that interesting!
What can we take home from this study?
Eating a low glycemic diet decreases the reductions in resting energy expenditure when dieting.Most foods aren’t going to instantly cause an increase in fat burning but choosing low glycemic foods over high glycemic foods will allow you to burn more fat and more calories over time.Eating a low glycemic diet usually means you will eat less carbs and more protein (the low GI diet had 24% less carbs and 12% more protein).

Helpful tips for avoiding those enticing foods

That fiery sensation that grabs hold of your lower chest after you eat something you know you shouldn't have. What often follows is that sour or bitter taste of acid reflux in your throat and mouth that can last minutes (if you are lucky) or hours (if you are not).

Yes, millions of us are familiar with the discomfort of heartburn, a condition in which stomach acids back up into the esophagus. The good news is that heartburn is largely avoidable if you steer clear of the top 10 heartburn foods. It also helps to avoid certain classic heartburn-inviting situations.

From coffee and liquor to tomatoes and grapefruit, experts tell WebMD that certain foods are known heartburn triggers.

Here's what you need to know about the top 10 heartburn foods.

Oranges, grapefruits and orange juice are classic heartburn foods. "These are very acidic," says Robynne Chutkan, MD. Chutkan is the founder of the Digestive Center for Women in Chevy Chase, Md. and a gastroenterologist at Georgetown Hospital in Washington, D.C. "As a result of being so acidic," she says, "they are likely to cause heartburn, especially when consumed on an otherwise empty stomach."

While they might be chockfull of healthy nutrients like lycopene, Chutkan tells WebMD that tomatoes are also highly acidic and likely to cause heartburn in those who are prone to it.

The acid antidote may be a sour ball, according to Daniel Mausner, MD. Mausner is the section head of gastroenterology at Mercy Medical Center in Rockville Center, N.Y. "Things that promote saliva -- like sour balls -- are good for acid reflux," he says, "because saliva neutralizes the acid that comes up from your stomach."

Bonnie Taub-Dix, MA, RD, says, "Some people with heartburn do not do well with either garlic or onion." Taub-Dix, a spokeswoman for the American Dietetic Association, is a nutritionist in private practice in New York City and Woodmere, N.Y. "It's all very individual," she says. For avoiding heartburn, she offers the following suggestion: "Keep a food log to help you track the foods that are your heartburn offenders, and try to develop a list of safe foods." Foods like broiled chicken, baked sweet potatoes, toast, or cottage cheese, she says, are on the safe side of the heartburn food list.

Pepper, Mexican food, chili, and any other food that is loaded with pepper or other spices can trigger heartburn, says Deepa A. Vasudevan, MD. Vasudevan is an assistant professor of family medicine at The University of Texas Medical School at Houston. He tells WebMD that avoiding heartburn isn't necessarily a matter of all or nothing. "If spicy food triggers your heartburn, avoid it. Then slowly reintroduce milder versions of whatever you like."
