  1. We extracted the following coefficients for our age-sex groups.
  2. (*) For non overweight adults in USA.
  3. The estimation of energy requirements of an individual is: BMR  =  BMRc  +  BMRs x Weight kg TEE  =  BMR x PAL
  4. For a group of N individuals of the same age-sex group with a total biomass “B”, BMR  =  N x BMRc  +  BMRs x BM kg TEE  =  BMR x PAL
  5. If that same group had a biomass due to overweight (BMI > 25) of “B25”, the energy required to feed that biomass would be: BMR25  =  BMRs x B 25 kg TEE25  =  BMR25 x PAL
