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.
Instant Knockout contains green tea and cayenne pepper – both staples of many popular fat burners. These ingredients are said to help burn more calories, which could lead to faster results. IK also contains glucomannan, a fiber which may promote fullness and reduce food cravings. These ingredients are joined by vitamin B6 and B12, GTF chromium, zinc, piperine and green coffee extract. The result? A natural supplement without any risky substances – and one that could help you achieve your goals faster.
Through the proliferation of beneficial bifidobacteria in the gut, certain studies have found that consuming more probiotics may be helpful for those trying to lose weight — since eating foods containing them is associated with enhanced weight loss and protection against obesity. (9) To consume more probiotics in your diet, try eating yogurt, kefir or cultured veggies at least a few times a week, while also considering a supplement.

Research suggests these magical pulses are one of the closest things we have to a fat-burning pill. For starters, beans are a great source of resistant starch, a type of slow-digesting, insoluble fiber that feeds the healthy bacteria in your gut, triggering the production of the chemical butyrate, which encourages the body to burn fat as fuel and reduces fat-causing inflammation. They're also one of the top sources of soluble fiber. A recent study by Wake Forest Baptist Medical Center researchers found that for every additional 10 grams of soluble fiber eaten per day, a study subject's belly fat was reduced by 3.7 percent over five years. Black beans? One cup boasts an impressive 4.8 grams of soluble fiber.
Top your salad with this lean protein and soon enough all your friends will be asking you to tuna-round so they can compliment your new slimmed down look. As a primo source of docosahexaenoic acid (DHA), canned light tuna is one of the best and most affordable sources of lean protein for fat loss, especially from your belly! One study in PLOS One showed that omega-3 fatty acid supplementation from fish oil was connected to a lower waist-hip ratio as well as lower levels of abdominal fat.
One 2009 report published in the Journal of Nutritional Biochemistry found that CLA has positive effects on energy metabolism, adipogenesis, inflammation, lipid metabolism and apoptosis. (6) A 2007 study published in the British Journal of Nutrition similarly found that supplementation of a CLA mixture in overweight and obese people (three to four grams a day for 24 weeks) decreased body fat mass and increased lean body mass. (7) And regarding CLA’s safety, there seems to be very little risk for adverse effects on overall blood lipids, inflammation levels and insulin response in healthy, overweight or obese adults.
To avoid feeling hungry after a workout, eat a snack with at least 12 grams of protein before exercising, says Dr. Cheskin. And if you’re still hungry afterward? First, check in with yourself and make sure it’s actual hunger and not dehydration, says Dr. Cheskin. Then, eat a protein-rich snack that also includes some carbs, like a protein bar with whole grains.
Most fat burners will suggest taking at least two doses spread out throughout the day. The timing of these doses is also important. It is usually advised to take doses right before breakfast and lunch. This will allow them to kick in to help you feel full after meals and will give you energy throughout the day. But be sure not to take them late in the afternoon or at night, otherwise they might end up keeping you awake. Getting a good night’s sleep is also an important part of losing weight. Remember that one.

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.

Ansari says alcohol can prevent weight loss in several ways, including the fact that heavy alcohol intake can stimulate food intake. "Binge drinking can overload the liver. The liver then prioritizes processing alcohol over other nutrients and then stores the protein, carbs, and fat as fat in the body," Ansari explains. The Centers for Disease Control and Prevention (CDC) defines binge drinking as having five or more drinks for men, and four or more drinks for women in two hours. "Also, alcoholic beverages are often mixed with sugar-rich beverages. Drinking more than moderate amounts of alcohol can cause calories to add up quickly," she says.

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.
Men of all ages – Pretty much anyone over 18 who wants to drop a few pounds may benefit from taking a fat burner. These supplements aid your body’s natural abilities to burn fat, so they simply make the process easier for you. Whether you’re looking to lose significant weight or just burn off some holiday fat, adding supplements to your diet may provide some help.

Sure, ketchup is tasty, but it's also a serious saboteur when it comes your weight loss efforts. Ketchup is loaded with sugar — up to four grams per tablespoon — and bears little nutritional resemblance to the fruit from which it's derived. Luckily, swapping out your ketchup for salsa can help you shave off that belly fat at home without a diet. Fresh tomatoes, like those used in salsa, are loaded with lycopene, which a study conducted at China Medical University in Taiwan links to reductions in both overall fat and waist circumference. If you like your salsa spicy, all the better; the capsaicin in hot peppers, like jalapeños and chipotles, can boost your metabolism, too.
