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: $\text{BMR\hspace{0.17em}}=\text{\hspace{0.17em}BMRc\hspace{0.17em}}+\text{\hspace{0.17em}BMRs\hspace{0.17em}x\hspace{0.17em}Weight}\left(\text{kg}\right)\to \text{TEE\hspace{0.17em}}=\text{\hspace{0.17em}BMR\hspace{0.17em}x\hspace{0.17em}PAL}$
4. For a group of N individuals of the same age-sex group with a total biomass “B”, $\text{BMR\hspace{0.17em}}=\text{\hspace{0.17em}N\hspace{0.17em}x\hspace{0.17em}BMRc\hspace{0.17em}}+\text{\hspace{0.17em}BMRs\hspace{0.17em}x\hspace{0.17em}BM}\left(\text{kg}\right)\to \text{TEE\hspace{0.17em}}=\text{\hspace{0.17em}BMR\hspace{0.17em}x\hspace{0.17em}PAL}$
5. If that same group had a biomass due to overweight (BMI > 25) of “B25”, the energy required to feed that biomass would be: $\text{BMR25\hspace{0.17em}}=\text{\hspace{0.17em}BMRs\hspace{0.17em}x\hspace{0.17em}B}25\left(\text{kg}\right)\to \text{TEE25\hspace{0.17em}}=\text{\hspace{0.17em}BMR25\hspace{0.17em}x\hspace{0.17em}PAL}$
