Explain how losing 10 pounds in one week is detrimental to weight management.
Our body will only burn about 2-3 pounds of body fat per week when we do everything right. The remainder of weight comes from lean body mass. When we lose lean body mass (muscle), metabolism is lowered. We are then burning less calories in 24 hours than we used to, and therefore, tend to put the weight back on and then some. Each time we roller coaster diet, the bodies metabolism is lowered. The key to weight management is elevation of metabolic rate and that is accomplished through exercise.
