You may also know this root veggie as a sunchoke since they’re the roots of a type of sunflower. According to a Canadian study, subjects whose diets were supplemented with a type of gut-healthy insoluble fiber called oligofructose not only lost weight but reported less hunger than those who received a placebo. Researchers discovered that the subjects who consumed the prebiotic fiber had higher levels of ghrelin—the hunger-suppressing hormone—and lower levels of blood sugar. And you guessed it: Jerusalem artichokes are one of the best sources of the fiber.
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.
Foods rich in the amino acid leucine can help build the lean muscle mass that’s needed to trim excess fat from your frame, according to Jennifer McDaniel, MS, RDN, CSSD, LD. It literally jumpstarts the process of developing muscle mass—and red meats are one of the best sources around. Go grass-fed to get the added benefits of omega-3s and conjugated linoleic acids—these two fatty acids help to decrease the inflammation in your body that causes fat storage.
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.
“Starting slow and working your way up is better than overdoing it and giving up,” says Gagliardi. “I like the idea of attaching the new behavior of taking a walk to an existing behavior.” An easy way to approach it: Commit to going for a quick 10-minute walk after dinner, and slowly increase the time as you become more comfortable with daily movement.
Researchers found that cinnamon has a type of antioxidant, which can increase insulin sensitivity and help you in stabilizing blood sugar effectively. You simply include 1/4 to 1 teaspoon of cinnamon to your diet such as hot cereal, yogurt, marinades, etc. to make blood sugar get into your cells, which is used for energy and thereby your body will store less fat than before.
That sour cherry is pretty sweet when it comes to your health. The results of a study conducted at the University of Michigan found that rats given high-fat foods along with tart cherries ditched nine percent more body fat than those in a control group over just 12 weeks. Cherries are also a good source of antioxidant pigment resveratrol, which has been linked to reductions in belly fat, dementia risk, and lower rates of macular degeneration among the elderly.
Carbs are not the enemy. Not whole-grain carbs, that is. People who ate three or more daily servings of whole grains (such as oats) had 10 percent less belly fat than people who ate the same amount of calories from processed white carbs (bread, rice, pasta), according to a Tufts University study. It’s theorized that this is due to whole grains’ high fiber and slow-burn properties, which keep you satiated longer.
Don’t let extra hours lounging in bed stand between you and a flatter stomach. While getting enough sleep can help boost your metabolic rate, sleeping in may undo any benefit you’d enjoy from catching a few extra winks. One Obesity study reveals that late sleepers who snoozed past 10:45 in the morning ate nearly 250 more calories over the course of the day, despite eating half as many fruits and vegetables as their early bird counterparts. Even worse, they chowed down on more salty, sugary, and trans-fat-laden fast food than those who woke up earlier. If you happen to head out of the house early, you’re in for an additional metabolic boost; researchers at Northwestern University have found that people exposed to just a short period of early morning sunlight had lower BMIs than their late-waking counterparts.
