Rating: 5 out of 5

1AND1 BURN is an all-natural fat-burning supplement that helps boost metabolism and calorie burn without the crash or jitters. It increases calorie expenditure without causing gastrointestinal issues. The supplement contains well-known fat-burning ingredients, including caffeine from green tea extract and apple cider vinegar.


If you’re naturally sensitive to caffeine (one cup of coffee and you’re flying), be careful with any fat-burning supplements containing caffeine as an active ingredient. Although BURN contains modest amounts of caffeine anhydrous, caffeine-sensitive people should be watchful of any caffeine content.

Bottom Line

1AND1 is so confident in its fat-burning supplement that it offers a 90-day money-back guarantee. The fat-burning formula contains seven carefully selected ingredients to support mood, increase energy, and boost calorie burn. Because of its clean profile, the supplement is extremely gentle on the stomach.

If you’ve ever experimented with fat burners you know that they too often promise the world but, when it’s time to deliver the results, they ultimately come up short. So, it’s refreshing when a fat burner comes along that offers realistic benefits and then actually follows through. That product is 1AND1 Burn and in this review, I’ll take you under the hood of this impressive weight loss aid.

What is 1AND1 Burn?

1AND1 Burn is a completely natural fat-burning and energy-boosting supplement. It is derived from natural herbal compounds to help remove excess body fat. This is achieved through three key mechanisms:

  • Speeding up the metabolism
  • Boosting energy levels
  • Suppressing the appetite

The metabolism-enhancing effects of 1AND1 Burn will allow you to burn more calories throughout the day and even during the night. Having more energy means that you will be able to exercise more intensely to burn off even more calories. Of course, the appetite suppressant effects also allow you to have fewer calories in your body.

To produce these body-transforming effects, 1AND1 Burn brings together the following seven all-natural ingredients:

  • Acai berry extract
  • Green tea extract
  • Garcinia cambogia
  • Caffeine anhydrous
  • Apple cider vinegar powder
  • Grapefruit powder
  • Kelp powder

Unlike many fat burners, which are heavily dosed with stimulants like caffeine, 1AND1 Burn will not produce a wired, jittery effect. It does include caffeine, but the dosage is moderate enough to produce a thermogenic, energy-boosting effect without getting you wired. The modest dosage also prevents the post-exercise crash that is common with many stim-based fat burners.

Who Should Use Fat Burners?

Fat burners are designed to be used by people over the age of 18. They are a supplement to fat loss and should not be used as the first line of attack in your weight loss journey. Before taking a fat loss supplement, you should be following a healthy, calorie-reduced nutritional plan and exercising regularly.

Fat burners are especially beneficial for people aged 35+, whose metabolisms have naturally begun to slow down. Bodybuilders and those who are working out to bring down their body fat levels in order to enhance leanness and vascularity are keen users of fat burners.

Fat burners should not be used by children under the age of 18 or pregnant or breastfeeding women. If you have a medical condition or are taking medication, you should consult your doctor before beginning to use a fat burner supplement.

How to Burn Fat With Fat Burners?

Fat burners combine a range of ingredients that work synergistically to speed up fat loss. Let’s learn more about the three basic categories of ingredients of fat burners, appetite suppressants, energy enhancers, and thermogenics. 

Appetite Suppressants

Appetite suppressants increase feelings of fullness to prevent snacking and help you to stick to a weight loss nutritional program. Among the most effective appetite suppressant ingredients are:

  • Garcinia cambogia
  • Grapefruit powder

Energy Enhancers

Energy enhancers encourage hormonal responses in the body that gives us more energy. One way they do this is by breaking the fatty acids that are inside our stored body fat. These fatty acids are then able to be used for energy. Three of the best energy enhancing ingredients are:

  • Caffeine anhydrous
  • Apple cider vinegar

Energy enhancers also stimulate the central nervous system to enhance energy levels.


Thermogenic fat burners boost the metabolism to increase calorie burn. They do this by stimulating the nervous system to generate heat and increase blood flow, leading to enhanced calorie burn. The most popular thermogenic ingredients are:

  • Caffeine
  • Garcinia cambogia

The best natural fat burning supplements will also provide extra health benefits. That is the case with 1AND1 Burn. Ingredients such as acai berry extract, kelp powder, and grapefruit powder combine to provide powerful immune support to help your body fight viruses and bad bacteria.

What is the Best Way to Use a Fat Burner?

Fat burners usually come in the form of capsules with serving sizes of between 8 and 10 grams. According to the dosage provided, the manufacturer may recommend taking capsules two or more times daily. For best results, you should take two capsules of 1AND1 Burn each day.

It is usually suggested that you take your fat burner supplement first thing in the morning on an empty stomach. It is usually mixed with water at a ratio of one scoop to 300 mls of water.

If you are taking a fat burner that contains stimulants such as caffeine, you should not do so within five hours of going to bed as it may prevent you from getting to sleep.

You should always avoid the temptation to take more than the recommended dosage of a fat burner supplement. If the label provides you with a dosage range, start out with the lowest amount and then increase up to the maximum as required.

In conjunction with the proper use of a fat burner, you should be doing weight training for fat loss and reducing your caloric intake.

Are There Any Side Effects?

There are a couple of side effects that you should be aware of when taking 1AND1 Burn. These are dehydration and sleep interruption. Dehydration is a side effect of the fat burner’s thermogenic effect. As your internal temperature increases, the body will utilize more water in order to maintain the body’s ideal internal temperature. As a result, you should ensure that you are drinking about 2 liters of water per day while you are using a fat burner.

The inability to sleep results from the stimulant effects of fat burners. The low level of caffeine in 1AND1 Burn will minimize this effect. As mentioned previously, however, you should not take a fat burner within 5 hours of going to bed.
