What changes in the body after 45
Two things happen at once and are often confused. Age-related muscle loss begins in the thirties and accelerates without resistance training, while falling oestrogen shifts fat storage from the hips and thighs towards the abdomen. The result for many women is a changed shape and rising waist measurement even when the number on the scale has barely moved. Because muscle is metabolically active, losing it also lowers daily energy expenditure, making previous eating patterns gradually less well matched to needs.
This is why generic advice to eat less and walk more disappoints so many women in this age group. Walking is valuable but does not preserve muscle. Reducing food intake without adequate protein and loading accelerates muscle loss. The approach that works targets muscle, protein and metabolic health rather than weight alone.
