Exercising regularly and watching your calorie intake are both positive steps towards losing weight, toning up, and burning body fat. Both require considerable dedication and willpower to gain visible results and to succeed in the long term.

However, with so many food temptations and other factors to consider that can hinder progress, sometimes extra help is needed to guarantee success. This is where fat burners can help you keep on track if they are used properly and as directed by the manufacturers. 

Fat burners are dietary supplements that contain either natural or artificial compounds that help to boost the body’s capability of burning stored up fat. This is mostly facilitated by increasing the body’s metabolic rate, which in turn helps to burn more calories. Fat burners can also reduce the amount of fat your body absorbs from food. Some fat burners even contain ingredients that suppress the appetite, making it easier to keep to a low-calorie intake diet.

1. PhenQ: Best Overall Fat Burner

PhenQ is a relatively new fat burner when compared to others on the market, but it has built a reputation over time as one of the most effective fat burners that you can try.

It aids dieting programs by suppressing the appetite and preventing overeating from food binging. It also blocks fat production and helps burn stored up body fat. PhenQ helps beat the blues as well by boosting mental well-being. This is important because many individuals can feel down mentally when they cease eating comfort foods, resulting in extreme cravings and a high probability of breaking diet regimes.

Whilst PhenQ works like other fat burners on the market, the special trademarked formula a-Laceys Reset®, contains a secret ingredient that allows it to perform better than other market leaders. This and all the ingredients included in PhenQ are prepared at FDA and GMP-approved facilities in the United States and the United Kingdom.

The active ingredients in PhenQ include Chromium Picolinate which is naturally found in vegetables, meat, and nuts. Chromium Picolinate is linked to blood sugar level control. Adequate levels in the bloodstream can help keep blood sugars steady and prevent hunger and cravings for sweet foods.

Regular capsicum consumption has been linked with lower rates of obesity in double-blind, randomized, placebo-controlled trials. In PhenQ, capsicum is the major ingredient of Capsimax Powder formula which is a blend of capsicum, black pepper, caffeine, and niacin. These increase body heat which is also known as thermogenesis, and this, in turn, burns calories and stored body fat.

Caffeine is also included in PhenQ because this stimulant helps to fight fatigue, decrease hunger, and burn fat. It can also help you to complete exercise programs because of the energy-boosting properties caffeine contains.

Nopal is also known as prickly pear extract. This species of cactus is thought to be beneficial to diabetics, it also helps increase energy levels along with keeping blood sugar levels in check. This extract has also been shown to aid weight loss.

L-Carnitine Fumarate is an amino acid that is found in nuts, green leafy vegetables, and red meat. It aids in the fat-burning process and helps boost energy levels as well.

PhenQ comes with a 60-day money-back guarantee and bulk buying is cheaper in the long run than buying individual bottles. 1 bottle costs $69.95, 2 bottles cost $139.90, but you do get 1 extra bottle free. 3 bottles cost $189.95 and included in this package are 2 free bottles of PhenQ, and Avana Cleanse.

    Leanbean: Best For Women

    Some fat burners work best for men, others for women, whilst some are effective for both sexes. Leanbean however, is a more female-focused fat-burning supplement formula.

    Leanbean works best when taken as part of an exercise plan and low-calorie intake diet. The ingredients included help boost metabolism, and energy levels, whilst at the same time reducing cravings and hunger. This means that even if you are juggling a typically hectic female lifestyle together with a dieting plan, then Leanbean can still be effective, even if you miss the odd workout or healthy meal. 

    Leanbean contains the appetite suppressant Glucomannan in a 3g daily dose which has been scientifically tested to be the most effective amount needed to keep you feeling fuller longer. Glucomannan is thought to absorb water in the stomach and intestines making you feel fuller for longer, without needing to snack between meals. It is also thought to slow the absorption of sugar and cholesterol in the gut.

    Leanbean also contains the nutrient choline that is found in certain foods such as nuts, beans, vegetables, and eggs.  It is made in the liver and plays a vital role in many chemical reactions within the body.

    Chromium picolinate is widely used for its blood sugar level regulating properties. It is also thought to lower cholesterol levels and aid in weight loss because it helps the body process carbohydrates and fats.

    Vitamin B12 and B6 are added as they help to produce energy and fight fatigue. A deficiency in B12 can lead to anemia. An adequate supply of B6 also helps regulate blood sugars. 

    Other ingredients include the electrolyte chlorine, the mineral zinc, green coffee, turmeric, the tropical fruit Garcinia Cambogia, acai berry, and piperine. These are bursting with antioxidants and have other health-boosting properties.

    There are various purchase packages to choose from including the complete bundle which is 4 months’ supply of Leanbean. This costs $189.97 and comes with a 90-day money-back guarantee. Other options include a 2-month supply for $119.98- and one month’s supply for $59.99.

    Instant Knockout: Best for Active People

    The last thing you would expect to receive a makeover is a fat burner. But if you have been on the market since 2014, then things change, as do breakthroughs in science. 

    Instant Knockout has been helping people lose weight, burn fat, and stay fit for years. It comes with such a high reputation that even pro athletes use it.

    The makeover comes in the shape of the new 2.0 Cut Above Formula. The main attributes of this new formula include appetite control, a thermogenic boost, and other ingredients to ignite your metabolic rate. All this from natural ingredients in a formula that was created for professionals but can be taken by all who want to see fast results.

    Instant Knockout Cut includes vitamin D3, which is the most absorbable form of vitamin D on the market. Most vitamin D comes from direct sunlight, but in the winter months, our stores can become depleted, and supplementation is needed. Vitamin D helps lower blood pressure and boost cardiovascular health, which is important for those who exercise regularly.

    Vitamin B6 and B12 help boost energy levels and fight fatigue. Both help the body turn food into fuel too, and this is vital in getting us through exercise regimes. Caffeine also helps fight fatigue but differently, and therefore this stimulant has been included in the formula as well. L-Theanine is added because it prevents the slumps in energy that can suddenly occur after a caffeine boost wears off.

    Green tea extract is packed with polyphenols, cayenne pepper boosts metabolism, as does black pepper extract. Glucomannan is included, as this extract of the root from the konjac plant, contains complex carbs that can boost energy.

    A bottle of Instant Knockout Cut costs $50.00, 2 bottles cost $100, and 3 cost $150, but you also get an extra bottle free.

    4. PrimeShred:  The Best Fat Burner for Men

    When people think of dieting, they mostly assume that it is a female pursuit, whilst men are more likely to body build instead. However, whether men are weightlifting or trying to lose excess pounds, fat burners can still increase the chances of success in fat and weight loss goals.

    PrimeShred is a high potency vegan and vegetarian formula that is tailored to men who want to lose weight and body fat, either through dieting and standard exercise or through weight training as well.

    Prime Shred bottle

    PrimeShred is different from the other fat burners already mentioned, because of the potency of the formula. Therefore, it is extremely popular with bodybuilders and those who regularly do any form of weight training. Described as a 3-stage approach to fat burning, PrimeShred firstly boosts the body’s fat-burning process by speeding up the body’s metabolic rate.

    Secondly, fat-burning hormones are activated in the body, and this helps to burn off extra hidden fat. Finally, the formula gives you extra energy to get through the most punishing of workouts that are needed to build lean muscle and increase overall fitness.

    The main ingredients that activate these three stages of fat burning are L-Tyrosine which enhances alertness, helping you stay focused during intense workouts. L-Theanine, which increases metabolic rate and helps to reduce the amount of fat and carbohydrates the body absorbs from food. Bioperine is included because it helps the body absorb all the active ingredients better, whilst DMAE increases acetylcholine which aids performance.

    The other fat burner regulars such as caffeine, cayenne pepper, green coffee, and green tea extract are also included here. An extra player found in PrimeShred is Rhodiola Rosea root. This is used as a trigger that activates an enzyme in the body to break down stored fat reserves.

    A single bottle of PrimeShred costs $49.99, but there is a shipping charge of $7.95. If you buy 2 bottles you get an extra bottle free all for $99.99, and there is no shipping charge either. Finally, you can get 3 bottles plus 2 extra bottles free for $149.99, again with no added shipping charges. There is also a 100-day return policy.

    5. Phen24: Best For Boosting Metabolism

    Another fat burner with an extra trick up its sleeve is Phen24. This formula concentrates on speeding up the body’s metabolism. This is because dieting can be hampered by a sluggish metabolism, no matter how well you eat and how often you exercise. 

    The ingredients in Phen24 concentrate on giving us the metabolic boost our bodies need to gain visible results from dieting and exercise regimes.

    Zinc is a trace mineral that is vital to health, even though we only need small amounts. Not only does zinc boost metabolism, but it also helps in wound healing and the proper functioning of the immune system.

    Copper increases energy levels, iodine aids thyroid function, L-Phenylalanine suppresses appetite, whilst other ingredients such as cayenne powder concentrate on firing up the body’s metabolic rate. 

    Phen24 comes in two different formulas, one for daytime metabolism and one for the night. The night formula contains different nutrients such as ascorbic acid, green tea extract, and hops which is a sleep aid.

    A box of Phen24 costs $74.99, 2 boxes plus 1 free box cost $149.99, whilst 3 boxes plus 2 free, costs $224.99. There is also a 60-day money-back guarantee.

    Do Fat Burners Actually Work?

    Americans spend over $2 billion a year on diet and fat-burning pills, but most of these supplements have not undergone proper studies under laboratory conditions. Some individual ingredients have been tested more thoroughly with promising results.

    These supplements have a great safety record though and since there is a lack of controlled scientific studies, the best way to answer the question as to whether fat burners work, is by asking those who use them as part of their dieting program.

    Conslusion

    There are many different brands of fat burners on the market, and it is always best to check the ingredients first before you buy fat burner supplements. This is mostly due to the inclusion of caffeine in some products which is a stimulant.

    Otherwise, most of the ingredients are vitamins, antioxidants, and other health-promoting substances that the body needs.
