How to Control Hunger, Eating & Satiety | Huberman Lab Essentials

Episode description

In this Huberman Lab Essentials episode, I explain how hormones regulate hunger, appetite and feelings of satiety (fullness), along with strategies to help control appetite.

I describe how the body senses nutrient levels and how the brain processes these signals to stimulate hunger or suppress appetite. I also discuss how certain foods can help curb hunger, while processed foods and emulsifiers can interfere with satiety signals, leading to overeating. Additionally, I cover how lifestyle factors such as exercise and meal timing regulate blood glucose levels, which in turn impact hunger and appetite.

Mindsip insights from this episode:

Avoid emulsifiers to restore satiety signals and prevent overeating

Emulsifiers in processed foods strip your gut's mucosal lining, which prevents your body from detecting nutrients and releasing satiety hormones, causing you to overeat.

Regulate meal times to control ghrelin and hunger signals

The hormone ghrelin is released based on your regular meal times, making you feel hungry at specific times of the day regardless of your actual blood sugar levels.

Utilize yerba mate to control appetite and manage blood sugar

Yerba mate tea increases GLP-1, a peptide that acts as an appetite suppressant and helps manage blood sugar, making it useful for extending a fast.

Beware of ketogenic diet's impact on thyroid hormone levels

A long-term ketogenic diet can alter thyroid hormone levels, potentially making it more difficult for your body to manage carbohydrates when you reintroduce them.

Engage in Zone 2 cardio to stabilize blood sugar levels

Performing Zone 2 cardio for 30-60 minutes, three to four times a week, makes your blood sugar so stable you can better tolerate occasional high-sugar foods.

Prioritize fiber before carbs to stabilize blood sugar

Eating fibrous vegetables first, followed by protein and then carbohydrates, can significantly blunt the blood sugar spike from your meal.

Recognize subconscious nutrient foraging to regulate eating

At a subconscious level, you are essentially 'fat foraging and amino acid foraging,' and you continue eating until your gut signals via the hormone CCK that you've ingested enough of these key nutrients.
