If you are someone who has been unsuccessful at weight loss or weight maintenance, maybe it’s time to look at what may be getting in the way – your metabolism. Metabolism, also known as basal metabolic rate (BMR) is the rate in which the body uses energy or calories to support keeping you alive – it’s all those involuntary things our body do without us even having to think about it – our heart beating, blood circulating, respiration, temperature maintenance, nerve activity and so forth.
