10. Green Tea
If you are not a coffee drinker, try drinking a cup of green tea. A study conducted in 2000 found that rats given an extract of green tea had a significant decrease in food intake and body weight. Green tea contains beneficial substances called polyphenols, which promote the burning of fat. It also contains caffeine, a stimulant and diuretic. According to numerous dieticians, you’ll want to drink 3 to 6 cups if you want it to manage your appetite effectively, but as green tea has caffeine in it, it can give you the jitters if you drink too much.
