losing weight quickly and restricting your diet can absolutely cause intense, constant hunger like you’re describing, and it is very likely related.
When you lose weight rapidly (3 kg in a week) or reduce calories, your body goes into a “survival/compensation mode.” Hormones change:
• Ghrelin (hunger hormone) increases strongly • Leptin (fullness hormone) decreases • Blood sugar may fluctuate → strong sugar cravings, shaky/empty feeling, nausea • Stomach acid can increase → burning or painful hunger above the navel
Because your current weight (~59–60 kg at 1.80 m) puts your BMI around 18–18.5 (borderline underweight), your body is likely trying to push you to eat more to restore weight, which explains:
constant hunger even after meals • painful empty sensation • sweet cravings • symptoms worse on empty stomach • nausea or stomach discomfort
This is very common after calorie restriction or being slightly underweight, not usually a dangerous disease.
What you should do: • Increase calories gradually (add 300–500 kcal/day) • Eat small frequent meals every 3–4 hours • Include protein + healthy fats (eggs, nuts, yogurt, peanut butter, rice, potatoes) • Avoid long fasting gaps • Stay hydrated
Thank you for your reply. I also experience very frequent mood swings accompanied by fatigue and weakness. Could this be related? What can I do to combat this?
What’s your age?
20 years. Why ?
Get CBC, Thyroid profile done
I’ve already done it, everything is OK
Rapid weight loss can indeed trigger intense hunger and sugar cravings, which your body is experiencing as a natural response to the significant calorie deficit or changes it’s detecting. When you lose weight quickly, especially by restricting your diet, your body might react by increasing levels of ghrelin, the “hunger hormone,” which tends to push you towards eating more. This is its way of trying to restore energy balance. Losing around 3 kg in a week might have disrupted your body’s homeostasis, and it may be trying to persuade you to consume more calories to get back to its previous state. This feeling of hunger, especially if it’s almost painful above the navel, could also be linked to your stomach producing more gastric juices or an empty stomach leading to discomfort. Sugar cravings often follow this cycle because simple carbohydrates offer quick energy, which your body craves when it’s undernourished.
Maintaining a balance is key, and you may need to reassess how you’re going about your weight loss. Gradual weight loss — no more than 0.5-1 kg per week — is generally more sustainable and less likely to lead to these intense hunger pangs. Also, ensure your diet isn’t just low in calories but rich in nutrients. Focus on whole foods that will fill you up more effectively, like fiber-rich vegetables, lean proteins, and healthy fats, which can promote satiety. Incorporating protein in every meal can help modulate hunger.
If the hunger persists or you notice any other troubling symptoms, consult with a healthcare provider to exclude any underlying conditions like hyperthyroidism or gastrointestinal issues that might be contributing. And ensure you’re not misinterpreting thirst for hunger – drinking enough water throughout the day can sometimes help manage hunger cues. User-centered, practical advice would focus on these aspects and encourage listening to your body’s needs more than strictly adhering to any rapid diet changes. If your symptoms are interrupting your regular life excessively or don’t improve with dietary adjustments, do seek further evaluation. Nutritional guidance can provide a more tailored approach in-house if needed.
Hello dear Yes hunger contraction are dependent upon tsh and metabolism of body. Your height / weight ration seems inconsistent and now totally inappropriate Iam suggesting some precautions for improvement. Please follow them for atleast a month Replacement of carbohydrates with protein diet Take nuts and fruits in between meals Be hydrated Avoid junk food Take zincovit multivitamin therapy onca a day for 1 month Take ashwagandha fir strength Do physical exercise atleast half an hour daily Avoid excessive thinking Add milk products for calcium level Hopefully improvement will occur In case of no improvement consult dietician in person for better clarity Regards
Hello Absolutely, what you’re describing is very common after rapid weight loss or strict dieting. Here’s why:
Why You’re Feeling Intense Hunger
When you lose weight quickly—especially by restricting calories—your body’s natural response is to increase hunger signals. This is a survival mechanism. Hormones like ghrelin (the “hunger hormone”) rise, making you feel hungrier, sometimes even painfully so. This hunger is often strongest above the navel (upper abdomen), and cravings for sugar or carbs are especially common.
After meals, your body may still feel unsatisfied because it’s trying to restore the energy (and sometimes nutrients) it lost. This can make hunger feel almost constant, even if you’re eating enough by the numbers.
*Is This Related to Your Weight Loss?*Yes, it’s directly related. Rapid weight loss and calorie restriction can: - Increase hunger hormones - Slow down metabolism - Cause cravings, especially for high-energy foods (like sweets or carbs) - Sometimes cause mild stomach discomfort or “hunger pangs” above the navel
What Can Help? - Eat balanced meals: Include protein, healthy fats, and fiber to help you feel full longer. - Don’t skip meals: Skipping meals can make hunger and cravings worse. - Avoid very low-calorie diets: Gradual weight loss is easier for your body to handle. - Stay hydrated: Sometimes thirst feels like hunger. - Consider a check-up: If hunger is extreme, persistent, or you have other symptoms (like weakness, dizziness, or digestive issues), see a doctor to rule out other causes (like thyroid or blood sugar problems).
In summary:
Your symptoms are a normal response to rapid weight loss and diet restriction. Your body is asking for more energy. If you want, I can suggest ways to manage hunger and maintain a healthy weight without feeling miserable.
Thank you
Thank you for your reply. I also experience very frequent mood swings accompanied by fatigue and weakness. Could this be related? What can I do to combat this?
Yes — rapid weight loss or strict diet restriction can cause intense hunger, because your body increases hunger hormones (like ghrelin) and slows metabolism to restore lost weight. However, persistent painful hunger above the navel, strong sugar cravings, and nausea can also suggest stomach irritation, gastritis, acid-related problems, or blood sugar fluctuations, not just dieting effects. Since symptoms have lasted a month, please consult a physician or gastroenterologist for evaluation and advice on safe nutrition and stomach health.
Thank you for your reply, but the hunger doesn’t go away even with Nexium. Perhaps it just needs more time?
Regarding the blood sugar fluctuations, what causes them and what can be done about them?
(I already saw a gastroenterologist, but he couldn’t tell me what was causing this hunger and said I don’t seem to have anything wrong with me.)
