New Delhi: Losing weight has become a major goal for a lot of people trying to improve health or get leaner. But weight loss can be a long process, hence, many are turning to all sorts of supplements in order to speed up the process. Green coffee is one of them, perhaps, it’s increasingly gaining popularity amongst fitness enthusiasts.
Green coffee bean extract, promoted by American celebrity physician and talk-show host Dr Oz, is one of the most popular weight loss supplements on the market. Basically, green coffee beans are coffee beans that have not yet been roasted. These coffee beans contain higher levels of chlorogenic acid than regular, roasted coffee beans. It is claimed that the substance, chlorogenic acid, may offer health benefits other than helping you lose weight.
Does green coffee help you lose weight?
Chlorogenic acid, the main ingredient in green coffee beans, is thought to affect how the body processes metabolism and blood sugar. Studies in animals (mice and rats) showed that the compound can help reduce body weight, as well as decrease fat absorbed from the diet. Chlorogenic acid may also help reduce fat stored in the liver and improve the function of adiponectin, the fat-burning hormone. Several studies suggested that caffeine can increase metabolism by up to 3-11 per cent.
Moreover, some controlled trials in humans showed that green coffee bean extract can aid weight loss. For instance, one randomised controlled trial involving 30 overweight individuals found that those who took instant coffee with green coffee bean extract lost more weight (about 5.4 kg) than those drinking plain instant coffee (1.7 kg).
However, more research is required since most human studies examining the effectiveness of green coffee beans for weight loss remain inconclusive. Additionally, green coffee may have other health benefits. It may help lower, blood pressure, reduce the risk of Type 2 diabetes and heart disease.
How to use green coffee for weight loss
The fact is that there’s no scientific evidence to determine an appropriate range of dosage for green coffee – both in children and adults. So, it’s best to follow the instructions on product labels or consult a physician or healthcare provider before using it. Yet, one serving (30 minutes before meal) is a common recommendation.
Is green coffee safe for everyone?
Green coffee bean extract appears to be safe when used appropriately – up to 480 mg daily in doses for about 12 weeks, as per WebMD. But since these coffee beans contain caffeine, it can cause numerous side effects when consumed in large doses – such as anxiety, rapid heartbeat, jitteriness, etc. Hence, people who are sensitive to caffeine should use it with caution. Additionally, pregnant or breastfeeding women and children are advised to avoid green coffee as it may not be safe for them.
