Serious analytical inconsistencies challenge the validity of the energy balance theory

open access: yesHeliyon, 2020
Energy metabolism theory affirms that body weight stability is achieved as over time the average energy intake equals the average energy expenditure, a state known as energy balance. Here it is demonstrated, however, that weight stability coexists with a
