Metabolism is your body's energy factory. It converts food into energy, powering everything from breathing to thinking. A slow metabolism can make you feel tired and sluggish, affecting your ability to stay active and alert all day.

Your metabolism controls how your body burns calories, impacting weight gain or loss. A slow metabolism makes it hard to lose fat, while a fast one helps burn more calories even at rest, preventing weight gain.

Your metabolism regulates blood sugar by turning carbs into glucose. This keeps your cells fueled and prevents blood sugar spikes and crashes. A healthy metabolism means steady energy and a lower risk of insulin resistance and type 2 diabetes.

Metabolism helps manage cholesterol, key for heart health. It regulates HDL ("good") and LDL ("bad") cholesterol levels, reducing plaque buildup in arteries and cutting the risk of cardiovascular disease.

Metabolism affects your appetite by signaling hunger or fullness to your brain. Hormones like ghrelin and leptin, which are involved in appetite regulation, are influenced by metabolism. A healthy metabolism balances these hormones, reducing cravings and promoting fullness after meals.
