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.
The phrase "slow carb" is anything but sluggish when it comes to blasting fat. Slow carbs are digested slowly, which keeps you feeling fuller and energized longer—and sweet potatoes are one of them. Among the magic ingredients here are carotenoids, antioxidants which stabilize blood-sugar levels and lower insulin resistance, which helps your body efficiently convert calories to energy rather than stored as fat. And their high vitamin profile (including A, C, and B6) give you more energy to burn at the gym.
Yohimbine: This ingredient, made from the bark of the yohimbe tree, is a popular stimulant in fat burners. It has been shown in a well-known study to produce significantly better fat loss results than a placebo among well-trained soccer players. However, more research is definitely needed, and yohimbine isn't for everyone! If you're prone to anxiety or are very sensitive to stimulants, proceed with caution when it comes to yohimbine. Some people find it makes them very jittery or anxious.
Bad breath is but a small price to pay for reaching your body goals, right? According to a recent Japanese study, when rats were put on a high-fat diet, the animals that were also given a garlic compound gained less weight than their peers. Experts attribute the fat-fighting benefits to a powerful compound in garlic called allicin. (It also happens to be the same compound that gives garlic its pungent taste and smell.)
Looking to lose weight fast in a healthy way? It’s tempting to turn to quick fixes like taking weight loss pills marketed as natural “fat burners.” In fact, surveys show that approximately 15 percent of U.S. adults have now used weight-loss dietary supplements at some point in their lives, with more women (around 20 percent) reporting use compared to men. (1) But before experimenting with these products, consider the fact that most diet pills, drinks and formulas (even those labeled “natural”) are capable of causing a range of unexpected side effects and interactions.
The internal and external obliques, which I like to call "nature's girdle," are located at the sides of the rectus abdominis. They are the muscles you use when you bend sideways at the spine or twist at the waist. They also contract to compress the abdomen, so you should work them just as hard as you work the rectus abdominis. Adding a twist to crunches works, as well as dumbbell side bends, but be careful not to use any jerky motions, especially if you've had back problems.
A big part of weight loss is simply being aware of the decisions you’re making. For example, when out at happy hour with friends, you may lose track of how much you're eating or drinking. But if you take a split second to step back and become aware of that fact, you’re able to course correct. “The awareness and then planning for what else I can be doing, that might give me the same benefit of eating comfort foods,” says Gagliardi.
If you've got weight to lose and you want it gone fast, try swapping out your usual proteins in favor of fish. Not only is fish lower in calories than an equivalent amount of beef or chicken, a study published in Obesity reveals study subjects who added omega-3 fatty acids, like those found in fish, to their diets shed more weight and had an easier time keeping it off than those who skipped them.
