What Are Natural Fat Burners?
Natural fat burners are dietary supplements formulated to increase the body’s metabolic rate and burn more calories than exercise and diet alone. All-natural fat burners expedite the weight loss process by burning calories and converting stored fat into energy.
Natural vs. Synthetic All-Natural Fat Burners
The best natural fat burners are made from natural and evidence-based ingredients, making them safe and effective. On the other hand, synthetic supplements, unlike the best natural fat burners, contain chemical additives that make them less safe.
For instance, Sibutramine, a recently banned synthetic fat burner, exposes users to heart problems, such as heart attack and stroke [11].

Common Ingredients in Best Natural Fat Burner Supplements
All six natural fat burner supplements mentioned above contain natural and scientifically backed ingredients. Common ingredients include:
1. Green Tea Extract
Green tea extract is a popular ingredient in weight loss products. It contains catechins that boost metabolism, improve performance during exercise, and enable various fat-burning hormones.
2. Green Coffee Bean Extract
Most weight loss products include green coffee bean extract because of its antioxidant properties. It contains chlorogenic acid, an antioxidant compound that boosts lipid and glucose metabolism. This effectively reduces carbohydrate absorption in the gut.
3. Caffeine
Caffeine is a stimulant that boosts fat-burning and promotes thermogenesis. These processes deliver energy that improves alertness and mental focus. Caffeine also reduces fatigue and boosts memory [12].
4. Black Pepper Extract
Black pepper extract primarily contains piperine, which prevents weight gain by hindering the production of fat cells. Research studies have shown that piperine reduces body fat by 12% and visceral fat accumulation by 38% [13].
5. Garcinia Cambogia
Garcinia cambogia has multiple roles in weight loss products. It regulates fat consumption, controls appetite, and reduces triglyceride and cholesterol accumulation [14].
6. Vitamins
Vitamins included in the best natural weight loss supplement are often in a higher concentration than the amounts acquired in a typical diet. Generally, fat-burning vitamins boost metabolism, reduce cravings, and improve strength.
A common type used in most of the best natural fat burners is the B vitamins, which facilitate protein, carbohydrate, and lipid breakdown by enhancing enzyme activities [15].
7. Minerals
Minerals also have an important role in promoting weight loss. Key minerals, such as magnesium, are converted into energy that helps regulate insulin. This improves exercise performance [16].
8. Amino Acids
Like vitamins and minerals, amino acids also contribute to weight loss. Most natural fat burner supplements use L-tyrosine, which stimulates metabolism to shed extra body fat. L-tyrosine also improves muscle strength, endurance, and energy, which benefits users who follow a strict diet and exercise routine [17].

Why Does the Body Store Fat?
The body naturally stores fat for two main reasons:
- As a source of energy beyond the stored glucose, also called glycogen.
- To reduce sugar levels in the blood after a heavy meal. High sugar levels in the blood are toxic and can damage the heart, nerves, and kidneys.
Stored body fat is later converted into energy through metabolism.
How Can the Best Natural Fat Burners Help?
Natural fat burner supplements are primarily enhancers. They increase the rate of metabolism and stimulate the conversion of stored fat into energy during physical activities.
Healthy Lifestyle Changes
As enhancers, natural fat burner supplements complement and accelerate weight loss, coupled with a healthy lifestyle. Therefore, you can’t rely on just these natural fat burner supplements to do all the work without changing your habits. You should embrace lifestyle changes, such as regular exercise and a healthy diet, to lose weight.
Natural Fat Burning Food to Include in Your Diet
The effectiveness of these all-natural fat burners relies on their nutrient content. They contain nutrients that suppress appetite and increase metabolism. However, apart from the ingredient formula, you should include the following fat-burning foods in your weight loss routine:
Protein
Proteins can accelerate weight loss because they increase satiety, effectively decreasing overeating. High protein foods include seafood, legumes, lean beef, soy, nuts, and seeds.
Whey Protein
Commonly found in dairy products, whey protein aids in weight loss by increasing satiety. It also sustains lean muscle mass.
Eggs
Most fitness enthusiasts avoid eggs because of their high cholesterol content. However, eggs have high-quality proteins, vitamins, and minerals, which support weight loss.
Chili Peppers
Including chili peppers in the diet helps in calorie burning. Chili contains capsaicin, which boosts metabolism and conversion of dietary food into energy [18].
MCT Oil
MCT oil from coconut and palm kernel oil supports weight loss by stimulating the production of satiety hormones. Without sufficient carbohydrates, MCT oil boosts the breakdown of stored fats into energy [19].
Omega-3 Fatty Acids
Omega-3 fatty acids from fish, flaxseeds, walnuts, and canola oil support weight loss by enhancing the regulation of food intake and overall well-being [20].
Green Tea and Black Coffee
Green tea improves the body’s metabolism, while caffeine increases endurance and workout performance. Black coffee and green tea can help users shed and maintain a healthy weight.

Tips To Get the Most Out of Your Natural Fat Burner
Apart from choosing the best natural fat burner, the following tips can help you achieve long-term weight loss results:
Try Aerobic and Anaerobic Exercises
Aerobic workouts, such as swimming, jogging, running, or cycling, can improve muscle endurance and promote weight loss. Short anaerobic exercises, such as HIIT, are effective for losing weight.
Balance Your Blood Sugar Levels
A high-carbohydrate diet can increase sugar levels in the body. Increased sugar levels increase insulin production in the pancreas, a crucial hormone in fat storage and weight gain processes.
Increased insulin levels hinder the body’s ability to burn fat into energy. Therefore, monitoring blood sugar levels helps users better understand their body’s reaction to lifestyle changes.
How Intermittent Fasting Affects Your Cells and Hormones
Intermittent fasting is an effective weight loss strategy as it prompts the body to switch from using glucose as an energy source to fatty acids. This increases the activity and regeneration of stem cells.
Intermittent fasting also maintains the body’s hormonal balance. This jumpstarts metabolism, improves sleep, and increases calorie burning.
