A person who expends 1900 kcal/day goes on a diet limited to 1250 kcal/day without any change in activity level. Estimate how much fat (adipose tissue) the person loses over the course of three weeks by maintaining this diet. Note that one pound of adipose (fatty) tissue stores about 3500 kcal of energy. Express your answer in pounds to three digits.

How many kilocalories of heat does an expenditure of 703 kJ produce? _____ kcal A pound of body fat stores an amount of chemical energy equivalent to 3500 Cal. When sleeping, the average adult burns or expends about 0.45 Cal/h for every pound of body weight. How many Calories would a 151 lb person burn during 7 hours of sleep?

A 100-kg person is working out in the gym dissipating 100 W of energy. How long would it take for their body temperature to rise by 1oC, ignoring all other forms of heat transfer in and out of their body? The specific heat of human tissue is 3.75 kJ kg-1 K-1. What is unreasonable about this calculation?

1. Let’s say that an average person consumes about 2000 calories per day over their entire lifetime. A calorie (Cal) is a unit of energy and one Cal equals 4186 ? (Joules). For someone who lives to a ripe age of 100 years, how much energy, in J will they require? What is their average power output in ?/? = ????? (abbreviated ?)? b) Given the total energy a person requires that you calculated above, use Einstein’s equation to determine...

A. Food Energy. Energy is stored in food as the potential energy of the electrical bonds in molecules. Your body converts food energy to mechanical energy and heat. Food energy is expressed in “calories”, which are actually kilocalories (kcal, with 1 kcal= 4.185 kJ) How many joules are in a 130-kcal serving of breakfast cereal? B.

38. BIO The rate at which a resting person converts food energy is called one's basal metabolic rate (BMR). Assume that the resulting internal energy leaves a person's body by radiation and convection of dry air. When you jog, most of the food energy you burn above your BMR becomes internal energy that would raise your body temperature if it were not eliminated. Assume that evaporation of perspiration is the mechanism for eliminating this energy. Suppose a person is jogging...

A 77.5 kg man, who is engaged in light activity and who is not sweating, uses internal energy at a rate of 220.9 kcal/h. The man then begins strenuous exercise, requiring 781.7 kcal/h. Assuming that the extra heat generated is dissipated through sweating and that 25% of the sweat evaporates, find the man's rate of sweat production in L/h. (Use 580 kcal/kg for the heat of vaporization of water at body temperature.)
