How Body Composition Changes
Energy Balance
Body weight changes are strongly influenced by energy balance: if energy intake is consistently below expenditure, body mass tends to decrease; if intake exceeds expenditure, body mass tends to increase. However, the composition of that change depends on protein intake, training, sleep, and the size of the energy deficit.
Fat Loss Priorities
Scale Weight Is Not the Whole Story
Water, glycogen, digestion, and menstrual cycle changes can alter the scale without reflecting true fat gain or loss.
