Explain Why sometime on morning we are so hugry?

, host of the , discusses various factors influencing hunger in the morning:

  1. Circadian Rhythms: Your body follows a circadian rhythm, a 24-hour cycle that regulates various physiological processes, including hunger.

  2. Blood Sugar Levels: After an overnight fast, your blood sugar levels are lower in the morning, prompting your body to signal hunger to stabilize these levels.

  3. Hormonal Fluctuations: Hormones like ghrelin (the hunger hormone) increase overnight, which can make you feel hungrier in the morning.

  4. Metabolism: Your metabolism slows down overnight and ramps up in the morning, increasing your energy needs and making you feel hungry.

Understanding these factors can help manage morning hunger effectively.


Well, sometimes I eat a lot of carbohydrates like rice or egg at night but at morning I'm too hungry


Feeling very hungry in the morning despite eating a lot of carbohydrates the night before can be due to several factors:

  1. Blood Sugar Levels and Insulin Response: High carbohydrate meals can cause a steep increase in blood sugar levels, followed by a substantial drop, making you feel hungry the next morning. To avoid these spikes, it's beneficial to include fibrous foods and proteins in your meal, which helps in regulating blood glucose more steadily 1.

  2. Hormonal Balance: Sleep deprivation can affect hormones like leptin and ghrelin, which regulate hunger and satiety. Lack of sleep reduces leptin (which signals fullness) and increases ghrelin (which signals hunger), making you feel hungrier in the morning 2.

  3. Timing of Eating: Eating carbohydrates later in the day or at night can impair insulin sensitivity due to the body’s circadian rhythms. This may lead to higher glucose and insulin responses for meals consumed late at night compared to the same meal eaten earlier in the day 3.

    Blood Sugar Control

    Andrew explains the importance of controlling blood sugar levels by eating fibrous foods first, followed by protein and then carbohydrates. He also discusses the impact of alcohol and physical activity on blood sugar levels.

  4. Cortisol Awakening Response: In the morning, cortisol levels rise, which can trigger glucose release from the liver to fuel the body. This response can be more pronounced in individuals with higher stress levels or insulin resistance, resulting in heightened hunger upon waking 4.

By understanding these aspects, you can better manage your morning hunger by improving meal composition and timing, and ensuring adequate sleep.
