What effect does ketosis have on appetite?

Ketosis typically suppresses appetite due to several physiological mechanisms. When the body enters a state of ketosis, it starts to burn fat for fuel instead of carbohydrates, leading to the production of ketones. These ketones can have appetite-suppressing effects on the brain, acting on hormones that regulate hunger such as ghrelin and leptin.

Additionally, foods that are higher in fat and lower in carbohydrates, which are usually consumed during ketogenic diets, tend to be more satiating. This increased satiety can lead to a reduced desire to eat frequently or in large quantities. In contrast, carbohydrate-rich foods can lead to more fluctuations in insulin and blood sugar levels, which can trigger hunger and cravings.

This combination of physiological and dietary factors explains why ketosis is often associated with a decrease in appetite, making it a desirable outcome for those aiming for weight loss.
