Hormonal

Older adults (64-78 years) exhibit an impaired ability to regulate food intake after weight loss, resulting in sustained lower body weight and significantly reduced hunger perception compared to young normal-weight adults.

For older adults, the biological drive to eat (hunger) may naturally decrease after weight loss, which can help maintain a lower weight without conscious effort. This is a biological shift, not a failure of willpower. If you are older and find you don't feel as hungry after losing weight, this is a normal physiological response that may help you maintain your new weight.

GoodSupportsHIGH confidence
Healthy OLD adults have an impaired ability to regulate food intake over at least 6 months following underfeeding compared with YNW adults, and a reduction in their perceived frequency of hunger may be a contributing factor.

Why this rating

Randomized controlled trial with a metabolic research unit protocol, though the hunger subgroup was small (n=19).
