As part of healthy lifestyle i want to lose weight. i am overweight. i know what to do - just eat less, but it is so difficult. are there healthy supplements that can increase my metabolism and decrease my appetite, or something like that?

Weight loss: Calories in and calories out is not a good way to loose weight. There are many different types of calories. Please see your doc and ask him/her about a low carb higher good fat food plan called the Ketogenic Diet. It will shift your body to burning fat rather than sugar as fuel. Ask about exercise too. Moderate walking is fine. Peace and good health.
