How we ranked
Many fat-burning supplements may claim to do something. As it can get very confusing, here we outline the criteria that we used to evaluate and choose each product for this review.
Is the company promising to burn 40 pounds in seven days, and all it takes are a few pills to do so? Be wary of companies making outlandish claims. Remember that losing weight is not an overnight ordeal, but a long and challenging endeavor.
Are you familiar with this brand or company? Are they known in the health or sports industry? Maybe you know a friend or acquaintance who’s heard of or used them?
Ideally, you should choose products from reputable companies but that doesn’t mean there aren’t great products from newer or less known brands.
You just need to understand what makes a good product and there are other factors to consider. Thankfully, we’ve done the work so you don’t have to.
Many fat burner supplements come in pill or capsule form; others come in flavored or plain powder form. The form doesn’t necessarily influence the effectiveness of the product. You may have a preference for either or.
Although, some products can vary regarding the dosage and sometimes even the quality.
That’s another reason to choose products from reputable companies as there’s less chance that you’ll get an underdosed or bad-quality supplement.
Always be mindful of the number of capsules or pills per serving, as well as per container. This also applies to products in powder form. These factors do, manytimes, determine what you get for the price.
Although, it may not matter as much with a quality product
Value for your money
Be aware that not all similar products are priced equally. This may be due to the number of ingredients, dosages, brand, etc.
it’s good to do a little research to ensure you’re getting a good overall value.
Amount of stimulants
Most fat burner supplements contain caffeine as the primary stimulant. For quick reference, there is 95mg of caffeine in one cup of coffee.
It is imperative to know that a product has safe and high-quality ingredients. One perfect way to find out is to check if the products are made in GMP/FDA approved or certified facilities.
User comments & reviews
In case you don’t have friends or acquaintances that have tried the product before, you can check out websites like Bodybuilding.com or Amazon, as well as other online sites related to diet and weight loss programs.
Checking user feedback on a product could be a great way to ensure you pick the best product for you.
Who should buy these fat burners?
If you are serious about losing excess fat and you have the money to shell out for your supplements, then fat burners can be a beneficial addition to your health and fitness regime.
More than your desire to shed those unwanted fats, you should consider your overall health. Most will contain stimulants that may not work well with some of your medications, or pre-existing medical conditions.
How do I pick a good fat burner?
Because you are trying to stay healthy and fit, we recommend choosing a fat burner that contains all-natural main ingredients.
Again, many fat burner supplements contain caffeine and the amounts do vary between the different options.
If you are going to use a product that has caffeine, MAKE SURE that you have built up a tolerance to it and that you are aware of how much the fat burner contains per serving. Be especially careful if you consume caffeine from other products.
Or maybe you want a product that’s caffeine-free.
This is something that you yourself will have to determine as there’s no right or wrong answer here.
Considering that you will be taking these supplements 1-2 x daily, try your best to choose a fat burner that is kind to your palate. This is where checking user feedback can be especially useful.
Fat burners give you energy
When you are working out, you need a decent amount of energy to start and sustain your exercise. For people who go to the gym or work out at home after a day in the office, or for athletes returning home from practice, there may not be enough energy left over.
Fat burners will help you fight this lack of energy by providing a natural boost so you don’t crash.
Fat burners help you manage hunger pangs
Hunger is one of the greatest hurdles in weight loss regimes. Fat burners have appetite suppressant ingredients that will help you deal with your hunger pangs. It tells your body that your stomach is already full.
Fat burners enhance your mood
As you are dealing with weight issues, your mood will likely swing back and forth, and it won’t help your desire to be fit as stress can drive you to junk food and a lack of physical activity. Fat burners have mood-enhancing properties that will help you manage your mood and keep motivated to achieve your health targets.
Like all medications, these supplements also come with possible side effects that you should consider before taking.
If you or your family have a history of heart problems, we highly recommended you consult with your doctor before using any performance-aiding supplements.
Aside from an increased heart rate, fat burners may also cause insomnia as ingredients like caffeine may disrupt your typical body clock and metabolism.
Nausea and Diarrhea
These are common symptoms that may sometimes occur when using multi-ingredient supplements.
It’s not uncommon for someone to take too much caffeine and experience symptoms of anxiety.
The best way to take fat burner supplements is with a snack or full meal but take them at least 30 minutes before eating. They shouldn’t be taken six hours before you sleep, or the extra energy could disturb your sleep.
It’s highly recommended to spread your dosage throughout the day to avoid unpleasant side effects. Also make sure to include off cycles to give your body time to rest and to not grow dependent on the supplements. You can also choose to switch between products after long usage as your body may become desensitized.
How long should you take fat burner supplements?
Four weeks is a good starting point. This will give your body sufficient time to react to the supplement and take affect. After a month, it is advisable to give your body a break.
Do the supplements impact sperm production?
The ingredient amino acid L-Citrulline affects sperm quality if you take three grams per day.
Do fat burners raise up your testosterone levels?
Vitamin D and Zinc are the elements that help increase testosterone levels, and these are not present in fat burner supplements.
Can you build muscles with fat burners?
These supplements will help you lose fat but not build muscles. You have to include rigorous workout training to your program in order to beef up your physique.
Losing weight and staying fit are essential activities both for health and personal reasons.
While these best fat burners for men will not cause significant fat loss all on their own, they can certainly help. You still have to maintain a proper eating regime and exercise too.
It’s not always easy to shed fat pounds because if it was, everyone would do it. Stick to a plan and remember why you’re doing this.
