[00:00:00]Getting older brings inevitable physiological changes that affect weight. Muscle loss, sarcopenia, starting around [music] age 30 to 40, we lose about 1% of our muscle mass per year. Muscle is metabolically active and burns more calories at rest than fat.

[00:00:15]Less muscle equals a lower resting metabolism, slower metabolism. This drop in muscle mass, combined with other cellular changes, lowers your basal metabolic rate, BMR, the calories you burn at rest. After 40, metabolism can slow by about 5% per decade. Hormonal shifts. Oh, women, menopause, declining estrogen levels can shift fat storage from the hips and thighs to the abdomen.

[00:00:42]It also contributes to sleep problems and muscle loss. Oh, men, andropause, gradual testosterone decline can lead to reduced muscle mass and increased body fat.
