What do you mean exactly by "growth rate", and what does that have to do with whether a faster metabolic rate results in increased rate of telomere shortening? --- When you eat food it is converted into glucose, raising the amount of glucose in the blood. The Body uses that glucose or raises the amount of Insulin in the blood which converts the glucose into fat. Cells have receptors for insulin, which allows them to regulate how fat is stored. Metabolic rate is the rate that you burn calories, which is directly related to blood sugar / insulin levels. Muscle / fat mass affects the metabolic rate. Caloric-restriction directly effects the blood-sugar / insulin system. The Methuselah mouse longevity is also affected by insulin levels.
