Is coffee good for weight loss?
Coffee is arguably the most well-known psychoactive substance in the world, and there is evidence that it increases concentration and improves exercise performance. But what other positive benefits are there?
While some research evidence suggests that caffeine can reduce appetite and boost metabolism, the overall picture is complex. Many studies are small-scale, so it is challenging to draw definitive conclusions.
IS COFFEE GOOD FOR WEIGHT LOSS?
Research shows that caffeine affects individuals differently, making it difficult to generalize its effects.
"Does coffee help you lose weight?" Probably not, and certainly not without a calorie deficit. Weight management is much more complex than drinking cups of coffee and watching the pounds of fat melt away," says Dr. Shyamala Vishnumohan, a nutrition expert.
So let's delve into coffee research and see what it may (or
may not) be able to do.
CAN SUPPRESS THE APPETITE
Research suggests that caffeine can reduce your appetite, potentially resulting in you taking in fewer calories. But there are caveats.
"While coffee may slightly reduce your hunger hormone, ghrelin, we're not sure how long the appetite-suppressing effects may last," says Dr. Vishnumohan. "For example, one study found that drinking coffee before a meal slightly decreases calorie intake. But the appetite-suppressing effects didn't last more than three to four hours."
CAN INCREASE METABOLISM
Another touted benefit of caffeine is that it boosts your metabolism and helps you burn more calories.
"Drinking coffee speeds up metabolism, increases fat burning through increased thermogenesis [heat production] and stimulation of neurotransmitters such as adrenaline," explains nutritionist Lon Ben-Asher.
