If you want to get rid of your health problems, you have to localize them first. Is your coffee intake too high? Do you consume too many candy bars instead of healthy fruit? All these factors pile up little by little and increase the amount of calories you get.
To help your organism fight with these issues you need to reconsider your way of life. Eat more healthy oils and avoid fats if you're eager to feel better than you do now. Check if you have any food allergies, too, to eliminate unpleasant consequences.
