If you're having a hard time cutting unwanted weight, you may want to consider other options, such as diet pills. While some of these over-the-counter pills contain the "best" compounds at promoting weight loss, they don't produce "wow" results. Consultation with a doctor is necessary to discuss safety and effectiveness of these types of diet pills and also to learn about prescription diet pill options.
Majority of diet pills contain caffeine as a single ingredient or in the form of an herb such as guarana, yerba mate or kola nut. As a stimulant, caffeine boosts metabolism, but generally not sufficient to create a significant weight loss, according to the Office of Dietary Supplements. The caffeine-containing herbs may help with weight loss by delaying gastric emptying - meaning they keep your stomach full longer - according to the study published in 2001 in the Journal of Human Nutrition and Dietetics. However, caffeine-containing diet pills cause mild but serious effects, such as nervousness, or serious conditions such as swelling of the brain.
Green tea is also a source of caffeine, but that's not the only active compound believed to help with weight loss. The tea also contains catechins, which are phytochemicals that may boost your metabolic rate. However, while green tea is a source of nutrition that help you burn calories, it doesn't help you cut much weight, according to a 2012 study published in The Cochrane Database of Systematic reviews.
Green Coffee Bean Extract
Green coffee beans, which are unroasted beans, are also a source of caffeine and offers high amounts of chlorogenic acid. This particular acid has been shown to help avoid the accumulation of fat in both mice and humans, according to the Office of Dietary Supplements. While it appears that green coffee bean extract is promising for weight drop, very few human studies without biased data exist, according to a 2011 review study published in Gastroenterology Research and Practice. To better assess how green coffee bean extract might help with excess weight, additional clinical study is necessary.
White Kidney Bean
White kidney beans are legumes native to Central and South America that put a stop to the breakdown and absorption of carbs and suppress appetite. When it comes to diet pills - the legume appears as Phaseolus vulgaris. When consumed as part of a reduced-calorie diet, participants in a small study published in 2014 in Obesity - lost 6 pounds over a 12-week period, compared to 2 pounds in the control group. However, a review research from 2011 published in the British Journal of Nutrition says much of the study on white kidney beans and weight loss are flawed, and suggests larger, more rigorous studies to figure out how well it works.
Chromium is a vital trace mineral that helps control your blood sugar levels, and fuels an active lifestyle by helping your cells access glucose, a fast and easy source of energy. It might help you boost your lean body mass and burn more. Chromium supplementation is associated with weight loss, according to a 2013 review study published in Obesity Review, which studied at the results from 11 prior studies. However, like other diet pills, chromium alone didn't trigger considerable weight loss; it seems to offer a simple benefit at best.
