- Green Tea
Research in clinical studies shows that flavonoids and caffeine present in green tea are substantial in boosting the rate of metabolism, fat oxidation, and insulin activity. Regular intake of green tea solution triggers a loss of around 2.9 pounds after three months of continued intake. In another study conducted by Smith K. Isabel, a certified dietician, losing weight by taking green tea requires you to work towards burning a minimum of one hundred calories per day. Smith further holds that care should be taken not to over-boil your green tea to avoid catechin compound destruction.
The University of Maryland’s Medical Department carried out a study in which it justified the presence of high EGCG polyphenol substances in all green tea strains. Further, the research held that green tea has the highest polyphenol levels as compared to all other types of tea.
Caffeine is a substance commonly found in coffee, green tea, and cocoa beans. It’s also a popular ingredient in commercial fat-burning supplements — and for good reason. Caffeine can help boost your metabolism and help your body burn more fat (4, 5, 6).
Research shows that caffeine can temporarily boost your metabolism by up to 16% over one to two hours (5, 6, 7). In addition, several studies have shown that caffeine can help your body burn more fat as fuel. However, this effect appears to be stronger in lean people than obese people (8, 9, 10). Unfortunately, consuming caffeine too often could make your body more tolerant to its effects (11). To reap the benefits of caffeine, you don’t need to take a supplement.
Simply try drinking a few cups of strong coffee, which is an excellent source of caffeine with many health benefits.
3. Green Coffee
What is Green Coffee?
Green coffee beans are simply regular coffee beans that haven’t been roasted and remain completely raw. In 2012, the Green coffee extract was promoted as a miracle weight loss supplement by American celebrity physician and talk-show host Dr. Oz.
Many health experts have since refuted the notion that it has any significant impact on weight. Even so, green coffee extract remains one of the most popular weight loss supplements on the market.
Several small studies have treated mice with the extract and found that it reduced total body weight and fat accumulation significantly. However, studies in humans have been far less conclusive (3, 4).
Most human research on green coffee has been inconclusive. While some participants lost weight, the studies were poorly designed with small sample sizes and short durations (5). Thus, no definitive evidence demonstrates that green coffee is effective for weight loss. Larger, well-designed human studies are needed.
What is Glucomannan?
Glucomannan is a natural, water-soluble dietary fiber extracted from the roots of the elephant yam, also known as konjac.
- Like other soluble fibers, it’s believed to promote weight loss in several ways (1):
- It’s very low in calories.
- It takes up space in your stomach and promotes a feeling of fullness (satiety), reducing food intake at a subsequent meal.
- It delays stomach emptying, contributing to increased satiety (2).
- Like other soluble fibers, it reduces the absorption of protein and fat (3).
5. Grains of Paradise
What is Grains of Paradise?
Grains of Paradise is a herb native to West Africa and actually belongs to the same botanical family as ginger. The Grains of Paradise plant has traditionally been used in African medicine as a powerful antioxidant and to treat digestive and intestinal issues and certain symptoms of diabetes. To understand how Grains of Paradise can help you burn fat, you first have to understand fat, or adipose tissue, in the human body. You have two forms of adipose tissue in your body: white and brown. White adipose tissue comprises large, round cells comprising a drop of lipids (fat) surrounded by cytoplasm and nucleus. White fat cells are designed to store energy for later, like if you haven’t eaten enough or used your existing energy stores. White adipose tissue is mainly located around the waist and thighs.
