Fun fact: Gut bacteria in your gut may also affect cravings, but more research is needed to confirm the link!
What are cravings?
Cravings are intense desires or urges to consume specific foods or substances, usually high in sugar, fat, or salt. Hormonal changes, emotions, or environmental cues can trigger them. Cravings differ from hunger, a physical sensation when the body needs fuel. While cravings can indicate a desire, they often come from psychological or emotional factors unrelated to physical needs. Although cravings can be hard to resist, many people experience them. However, giving in to cravings too often can lead to unhealthy eating habits and weight gain. Hence, it is vital to develop strategies that can effectively manage cravings.
Physical reasons you may have cravings:
- A diet low in nutrients: Even if you've eaten enough calories, if the calories are from protein and fibre, it's unlikely you will feel full. A low-nutrient diet may cause hunger or cravings.
- Pregnancy: hormones can intensify cravings by affecting smell and taste receptors.
- Premenstrual syndrome (PMS): changes in estrogen and progesterone before menstruation can lead to increased cravings for carbohydrates. Mood imbalances can also increase cravings for these types of foods. Studies suggest that a woman's resting metabolic rate increases during ovulation, which may be linked to cravings.
- Sleep debt: not getting enough or poor-quality sleep can disrupt the hormones that regulate hunger, fullness, and sleep cycles.
- Highly processed foods: high in added fat and sugar could cause addiction-like symptoms increasing cravings, based on some scientific evidence (They can cause as much dopamine release in the brain's reward system as nicotine and alcohol).
- Low hydration: before you think you're hungry, check if you're dehydrated first! Too little fluid intake can intensify feelings of hunger or cravings in most people.
- Gut bacteria: in your gut may also affect cravings, but more research is needed to confirm the link!
- Physical activity: can help reduce food cravings. On the other hand, moving less than you usually do may trigger food cravings.

Why do I get more hungry when I don't sleep well?
Poor sleep can disrupt hormones that control hunger and appetite. For example, lack of sleep may increase ghrelin, which stimulates appetite, and decrease leptin, which signals fullness. This can cause increased hunger and decreased satisfaction after meals.
