DO IT: Assume a pushup position with your hands below your shoulders and your body forming a straight line from your head to your heels. This is the starting position. Lifting your right foot off of the floor, drive your right knee towards your chest. Tap the floor with your right foot and then return to the starting position. Alternate legs with each repetition.
So, what is a fat burner? As explained in the journal Obesity Reviews, 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."[1] However, that's a wide range of functions, and in pill form especially, it can mean a lot of things! So, let's dig a little deeper.
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)
Green Tea: Green tea and green tea extracts have been shown to activate the body's thermogenic fat-burning activity. A study published in the American Journal of Clinical Nutrition found that men who ingested the active ingredient in green tea (catechins) significantly reduced their total fat area, waist circumference, skinfold thickness, and subcutaneous fat area.[2] As exercise physiologist Nick Coker explains in the article "Your Expert Guide to Green Tea," taking this ingredient with caffeine has been shown to make it even more effective.
Aim to do ab work three or four times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs three or four times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.

Weightlifters – Weightlifters, bodybuilders and fitness enthusiasts can greatly benefit from these products. Because of the higher-than-average calorie and nutrient needs of regular trainers, it can be easy to put on some extra fat while you’re building muscle. By adding a weight loss supplement, you can get that toned definition you’re after, without sacrificing your muscles.
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.

Apple cider vinegar, in particular, is composed mostly of acetic acid, which has been shown to delay gastric emptying and slow the release of sugar into the bloodstream. Research published in the journal Bioscience, Biotechnology, Biochemistry found that a small pool of study participants given ACV over a 12-week period lost more weight, body fat and inches from their middle than participants that were given a placebo. How does it work? Besides maintaining stable blood sugar levels, ACV produces proteins inside the body that burn fat.
Had enough of boring rice? Add some bulgur into your diet. Although this grain is traditionally used in tabbouleh—a staple dish of Mediterranean cooking made by combining bulgur with chopped parsley, garlic, diced tomatoes, olive oil, and lemon juice—you can also use it as a base of salad bowls or a side for a chicken dish. This cereal will help you burn fat thanks to boasting over eight grams of belly-filling fiber; A study published in the journal Annals of Internal Medicine found that by simply increasing the amount of fiber you eat each day (to 30 grams) while keeping calories the same could help you lose weight, lower blood pressure, and improve your body's insulin response as effectively as more complicated diets that try to overhaul your entire diet.
Most weight loss supplements are not tested in clinical trials or included in evaluation studies conducted under well-controlled conditions with average human volunteers. Weight loss pill manufacturers are not required to test new ingredients or even to list things like potential side effects on the product’s label. Therefore it can be hard to tell what type of ingredients you’re even ingesting when consuming weight loss supplements or how you’ll react to different dosages.

The main ingredient in most fat burners is caffeine, which helps you lose weight by increasing your metabolism and helping the body use fat for fuel. It also helps provide energy for exercise and other calorie-burning activities. In the body, caffeine increases the breakdown of fatty acids that reside in adipose tissue—also known as belly fat. Once the fatty acids are broken down, they enter the bloodstream and can be burned up by our bodies to create energy.

Third on our best fat burners list is Hourglass, a 90 capsule fat burner which has an impressive selection of ingredients and attractive looking packaging. You might be put off by some of the more female orientated aspects of the product, including the marketing and the look of the brand, but don’t be. There’s no such thing as a gender specific fat burner. Men and women’s bodies are almost identical so there’s no reason why this product won’t work for any man. The best way to prove this is to look at the ingredients. As you’ll see, they’re common in many male targeted fat burners.


Hydroxycut Hardcore Elite is a great product, offering some of the most high-quality fat burning pills on the market. Hardcore Elite contains ingredients to target the most important aspects of fat burning: metabolism, thermogenesis, energy and more. All wrapped up in one convenient package, this product provides an easy way to increase your fat burning potential. Unfortunately, it does not contain any hunger suppression ingredients, which can be a downside for some people who have difficulty sticking to their diets.
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.
Super HD is a great product containing some of the best weight loss ingredients that work well by targeting the various aspects that are important to burning off fat. With only 2 capsules needed per day (compared to 4-6+ with other products), Super HD is also very convenient. Lastly, the backing of a respectable company like Cellucor makes this product one of our top recommendations.

Known as "forbidden rice" because only emperors were allowed to eat it, black rice may be the cheapest source of antioxidants around. According to the American Chemical Society, black rice has more antioxidants than a spoonful of blueberries, with more satiating fiber, more vitamin E, and less sugar. More antioxidants mean less inflammation, which means less fat storage for you.


How could the “fatty” foods mentioned above that contain CLA be good for reducing body fat? The jury is still out regarding the effects of CLA on promoting weight loss, but results from certain studies suggest that CLA (taken either alone or along with supplements like creatine and whey protein) can help increase strength, reduce appetite and cause other beneficial changes in body composition.

Whether you're adding it to your smoothie or having it as the perfect post-workout recovery fuel, Greek yogurt will help you build muscle. This creamy snack is brimming with muscle-building protein—about 20 grams in a 7-ounce cup. It has the one-two punch of vitamin D and calcium, which turn off cortisol, a stress hormone that causes the body to hang on to belly fat. Don't believe us? Take it from the researchers at the University of Tennessee who found that people who ate 18 ounces of Greek yogurt a day lost 22 percent more weight and 81 percent more belly fat than those who didn't.
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.

CLA is the name given to group of chemicals found in the fatty acid called linoleic acid. Because it’s a type of polyunsaturated fat, we don’t make conjugated linoleic acid on our own and must obtain it from the foods in our diets. A few of the major sources of CLA in your diet may include full-fat dairy products like whole milk or cheese, beef, and butter. CLA is also found in some bodybuilding supplements, protein powders or weight loss formulas.

Many television ads are now pitching devices that supposedly stimulate muscles to contract repeatedly without exercise. I even saw an infomercial for an "ab belt" that claimed it does the work of 700 sit-ups in 10 minutes! The ad shows people doing various abdominal exercises the wrong way, hating every second of it, versus smiling men and women going about their days with "Ab-whatevers" strapped around them. How enticing!
If you want to lose fat, you have to eat fat...the right kind, that is. Adding healthy fats, in the form of monounsaturated and polyunsaturated fats, can help you feel more satisfied with your meals. Yasi Ansari, M.S., R.D., C.S.S.D., national medial spokesperson for the Academy of Nutrition and Dietetics, says, "Fat sources that I recommend boosting in the diet come from unsaturated fatty acids found in foods like olive oil, nuts, avocados, fatty fish, and eggs, as they can help increase satiety while providing a variety of health benefits when consumed in moderation." You can increase your intake of healthy fats by adding some chopped avocado into your salads, enjoying wild salmon twice a week, and having a little peanut butter with your post-workout snack or smoothie. Just remember to enjoy them in moderation as they're still very calorie-dense, Ansari says.
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.
A scoop of guacamole is one of the most effective fat-burning, hunger-squashing snacks known to man. Not only are avocados rich in vitamin B6—which directly counteracts the belly-fat-building stress hormone, cortisol—they're also full of monounsaturated fat. This healthy fat may actually prevent body fat distribution around the belly by down-regulating the expression of certain fat genes, according to research in the journal Diabetes Care. These same satiating fats may also be the reason behind another study that found people who ate half a fresh avocado with lunch reported a 40 percent decreased desire to eat for hours afterward.
Sometimes, to whip your body into shape, you have to get a little nutty. While nuts are high in fat, it's that very fat that makes them such powerful weapons in the war against a ballooning belly. In fact, a study published in Diabetes Care revealed that study participants who consumed a diet rich in monounsaturated fats, like those in nuts, over a 28-day period gained less belly fat than their saturated fat-consuming counterparts while improving their insulin sensitivity.

Hourglass contains a great ingredient portfolio, enough to easily compete with many of the market leading fat burners. For instance, you’ll find glucomannan, a root extract that sits undigested in your stomach for a while to stop you from getting annoying hunger cravings between meals (and of course to stop you snacking). It contains green tea extract and black pepper extract (bioperine) which are found in many fat burners. It also contains a range of vitamins including Vitamin B6, Vitamin B12 and Vitamin D3.
