You're not alone if you need coffee to get through the day, but can it also aid in weight loss?
Coffee is the world's most popular psychoactive stimulant, and research suggests it promotes focus and exercise performance. What else is good?
Caffeine may lower hunger and enhance metabolism, although the data is mixed. It's hard to draw conclusions from small-scale investigations.
A flavoured latte has much more calories than an espresso. Caffeine supplements may cause sleeplessness, restlessness, elevated heart rate, and nausea.
Hormones and age have a part, but a balanced diet is key. The CDC recommends concentrating on a nutrient-dense diet, portion management, and exercise.
Black coffee has almost no calories, so it's OK to drink it sometimes when dieting.
The jury's still undecided on whether coffee boosts metabolism and reduces hunger. Caffeine affects people differently, making it difficult to generalise its effects.
