Resolve to do more prying. Oysters are one of the best food sources of zinc, a mineral that works with the hormone leptin to regulate appetite. Research shows that overweight people tend to have higher levels of leptin and lower levels of zinc than slimmer folk. A study published in the journal Life Sciences found that taking zinc supplements could increase leptin production in obese men by 142 percent! A half-dozen oysters only have 43 calories but provides 21 percent of your RDA of iron—deficiencies of which have been linked to a significant increase in fat gene expression.


Green tea has been tested in many studies, and results have shown that it can help you burn up to 16 percent more fat each day. Green select phytosome is another form of green tea extract, and one study found that taking it caused individuals on a diet to lose more than 30 pounds in three months, as compared to the 10 pounds that diet-only participants lost.
One of the reasons your metabolism isn't burning away fat as efficiently as you'd like? Look to your magnesium levels. This essential micronutrient is required for the body to produce and store energy, and also helps boost lipolysis (a process by which your body releases fat from its stores to use as energy)—yet 75 percent of Americans do not get their RDA of this important metabolism-boosting mineral. Just a half cup of pumpkin seeds provides nearly 100 percent of your daily magnesium needs.
According to the School of Sport and Exercise Sciences at University of Birmingham, “The term ‘fat burner’ is used to describe nutrition supplements that are claimed to acutely increase fat metabolism or energy expenditure, impair fat absorption, increase weight loss, increase fat oxidation during exercise, or somehow cause long-term adaptations that promote fat metabolism.” (3)

While many people turn to artificial sweeteners in a misguided attempt to whittle their waistlines, those fake sugars are likely to have the opposite effect. According to Yale researchers, artificial sweeteners are actually linked with an increased risk of abdominal obesity and weight gain, possibly because they can trigger cravings for the real stuff and spike insulin levels in a similar fashion to real sugar.

Knowing that dietary supplements — including weight loss pills, herbs, enzymes and teas — are not regulated by the Food and Drug Administration (FDA) in ways that other medications are, you may be wondering if they’re safe to consume. (2) Better yet, do weight loss pills or other fat-burning supplements even work, making them worth any potential risks involved? Studies have found that risks of fat-burning supplements can include nausea, headaches, anxiety, indigestion and trouble sleeping. Most adverse effects are caused by factors like interactions with medications, ingesting too much caffeine or consuming “filler” ingredients not even listed on the product’s label. While weight loss products may possibly give you a lift in energy and mood, they likely won’t be enough to sustain any real weight loss without other lifestyle changes.
A good supplement will have riboflavin and possibly dicalcium phosphate and/or vegetable cellulose. Supplements usually contain 2% or less silica and vegetable magnesium stearate. Ensure that the dosage instructions are in keeping with the daily dosage recommendation. Remember, you don’t need a whole ton. Anything your body doesn’t need, you’re just going to lose down the toilet!
Caffeine is often included in fat-burning supplements the form of yerba mate or guarana — however, manufacturers may include these substances in amounts they’re rarely used otherwise. Caffeine is a common weight loss ingredient because it often has the effect of dulling someone’s appetite and help increase energy for activity. However, too much caffeine can cause side effects like jitteriness, headaches, insomnia, anxiety, heart palpitations, diarrhea and more. 

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 most basic approach to weight loss is burning more calories than you consume. For instance, since 3,500 calories equals one pound of fat, a weight loss app—or even just a pen and paper—can help you decide how many calories you need to cut from your diet or burn at the gym in order to meet your goals. “If you were to burn 500 more calories per day seven days a week, that would lead to 3,500 calories in a week and one pound of weight loss,” says Gagliardi.

Many teas have been shown to boost metabolism, block the creation of new fat cells, speed the release of fat from cells, and actually turn off fat genes due to their catechin levels, but green tea has a leg up on the competition. This magical elixir is particularly high in the antioxidant ECGC, the compound that burns fat and stops it from forming. Pair your tea with a workout for a fat-burning bonus. Exercisers who drank four to five cups of green tea daily and worked out for 25 minutes lost more belly fat than their non-tea-drinking counterparts, a study published in The Journal of Nutrition found.
LeanBean is the self-described supplement ‘exclusively formulated for women’. Said to ‘harness the power of nature’ to complement your healthy lifestyle.

The LeanBean formula contains 12 ingredients and we’ve rounded them up for you to see how well researched and developed it really is.
Replicates the energy, fat loss, mood boost, and performance-enhancement of the ECA stack, in a safe and legal way. Don’t know about the ECA stack? It was used by just about everybody at one point for being highly effective at boosting energy and melting fat through the combination–or “stack”–of three key ingredients, one of which was banned for being too effective.
You say tomato, I say 9-oxo-ODA. That's the name of a compound found in the brilliant red fruits that Japanese researchers recently discovered can effectively activate your DNA to burn more fat. Tomatoes are also brimming in beta-carotene and lycopene, two potent antioxidants that mop up harmful compounds that promote fat storage. One Journal of Nutrition study found people whose diets contained the most beta-carotene and lycopene had the smallest waists and the least belly fat. And at only 5 calories apiece, grab a few sun-dried tomatoes! Cooked tomatoes contain more bioavailable lycopene than raw tomatoes, according to Cornell University researchers.

However, too much caffeine can cause side effects like jitteriness, headaches, insomnia, anxiety, heart palpitations, diarrhea and more.

It’s important to do full-body strength training if you want to lose belly fat—especially if you’re trying to keep it off for the long haul. “Strength training should be a part of just about everybody’s exercise plan,” says Dr. Cheskin. That’s because strength training helps you build muscle, which will replace body fat. And because muscle is metabolically active, you'll continue to burn calories after working out, thereby, reducing overall body fat. Bonus: When your metabolic rate becomes faster due to muscle growth, you’ll have a little more wiggle room in your diet if that’s something you struggle with, says Dr. Cheskin.

Red is one of the best colors for weight loss. That's because the color is due to higher levels of nutrients called flavonoids—particularly anthocyanins—which calm the action of fat-storage genes, according to Oxidative Medicine and Cellular Longevity research. In fact, red-bellied stone fruits like plums boast phenolic compounds that have been shown to "turn off" fat genes. Plus, their pectin—a gelatin-like type of fiber found in the cell walls of fruits—limits the amount of fat your cells can absorb, as shown by a Nutrition & Metabolism study.
