Having very low appetite since childhood, feeling nauseated when trying to eat more, and being unable to gain weight usually means your body has a **slow-appetite pattern** and possibly weak digestion. This is not your fault — it is a long-term pattern where your stomach signals get full quickly, so you cannot eat enough calories to put on weight.
This can also happen due to low stomach acid,
vitamin deficiencies, stress, irregular meals, or long gaps between meals. When appetite is low, even healthy food will not help with weight gain.
You need small, frequent, high-calorie meals instead of trying to eat large plates. Smoothies, shakes, curd, peanut butter, banana, nuts, ghee, paneer, eggs, and soft foods help you gain weight without nausea.
I can prepare a full weight-gain diet plan for you and guide you on how to increase appetite gradually without discomfort. Please consult me for a better solution.
