Can I speed up my metabolism? There are many pills, supplements and foods that claim to speed up the metabolism and burn fat. Most of these claims are unproven.
Some chemicals, such as nicotine and caffeine, do have a small effect. However, any increase in the metabolism may be accompanied by an increase in the heart rate and other side-effects, and so aren't recommended as a treatment for obesity.
The fact is no single ingredient will melt body fat away without some effort on your part to reduce the amount of calories you eat.
How can I burn calories? The best way to burn calories is to increase your levels of physical activity. The amount you'll burn depends on your body size, age and gender, but as a rough guide:
60 minutes of gardening burns 300 kcals 60 minutes of walking burns 200 kcals 90 minutes of football burns 600 kcals 45 minutes of dancing burns 450 kcals
