Many teenagers notice that their appetite changes during puberty. Some feel hungrier than ever, while others experience hunger that comes and goes unpredictably. Sometimes it feels like nothing satisfies the body, and other times hunger almost disappears. All of this is a normal part of how hormones shift as the body grows.

When puberty begins, levels of estrogen, progesterone and a small amount of testosterone rise. These hormones influence the body’s energy needs and how the brain regulates hunger. Because the body grows rapidly during this period — muscles, bones, brain and skin — it uses far more energy than before. This makes the body signal hunger more often. At the same time, hormones work in waves, which means appetite can also rise and fall in waves.

Hormonal changes also affect ghrelin and leptin, the hormones that control hunger and fullness. During puberty, these signals can become irregular, making hunger feel sudden, strong or unpredictable. It’s also common to crave certain foods, especially when the body needs quick energy.

Emotional changes play a role too. When feelings shift, appetite often shifts with them. Stress, worry or tiredness can decrease appetite for some and increase it for others. It doesn’t mean anything is wrong — it simply shows how sensitive the body is to hormonal and emotional changes during this time.
