Do you know what your BMR is? If not you should!!! BMR is your basal metabolic rate which tells your how much energy, otherwise know as calories, you need to consume daily for your body to function. Once you know your BMR you will know if you are currently over or under eating. If you want to loose weight your caloric intake should be close to your BMR and if you wish to put on weight you should be having more calories then your BMR.
