A diabetologist has explained why some people feel hungry shortly after eating and said that the issue may be linked to blood sugar fluctuations rather than poor appetite control. In a discussion on post-meal cravings, Dr Varun Suryadevara, consultant endocrinologist and diabetologist at Apollo Hospitals, Bannerghatta Road, Bengaluru, noted that the phenomenon is often driven by the body’s response to certain types of carbohydrates rather than psychological factors such as stress or boredom.

According to the specialist, meals high in refined carbohydrates such as white rice, maida-based bread and sugary foods can cause a rapid spike in blood glucose levels. This triggers a strong insulin response from the pancreas, which helps move glucose from the bloodstream into the body’s cells. However, when the insulin surge is excessive, it may lead to a sharp drop in blood sugar levels soon after eating, creating a “crash” that can leave the body signalling hunger even though a meal was recently consumed.

The doctor explained that this cycle can result in repeated cravings, particularly after meals rich in simple carbohydrates. In some cases, frequent post-meal hunger may also indicate insulin resistance, a condition in which the body’s cells do not respond effectively to insulin. When this happens, glucose remains in the bloodstream instead of being efficiently absorbed, leaving cells without adequate energy and triggering persistent hunger signals despite sufficient food intake.

To break this cycle, Dr Suryadevara recommended combining carbohydrates with protein, healthy fats and fibre-rich foods in every meal. He suggested options such as eggs, sprouts, paneer, nuts and seeds along with vegetables, as these combinations slow digestion and help maintain more stable blood sugar levels. This approach, he said, reduces sudden spikes and crashes that contribute to post-meal cravings.

The diabetologist also advised paying attention to food order by beginning meals with vegetables and proteins before consuming carbohydrates. This can help moderate glucose absorption and reduce sharp post-meal blood sugar increases. He further highlighted the importance of staying hydrated, noting that mild dehydration is often mistaken for hunger and may lead to unnecessary snacking.

Dr Suryadevara added that persistent hunger despite adequate meals could be a sign of polyphagia, particularly if accompanied by symptoms such as fatigue, sudden weight changes or frequent urination. In such cases, he advised consulting a medical professional and undergoing tests such as HbA1c or fasting insulin levels to assess underlying metabolic conditions.
