Hey...
Some tips to increase appetite are mention below..
1. Take a walk. If a poor appetite is caused by depression, a stroll outside can raise your spirits.
2. Avoid going long periods of time without eating. Your stomach will shrink.
3. Gradually eat more food each day. Your stomach will expand over time.
4. Reduce your fiber intake. Eating fiber makes you feel full which is great when you’re trying to lose weight but when you need to increase your appetite, eating less fiber leaves more room in your stomach for high calorie foods.
5. Choose high-Calorie, high-nutrient foods that are less filling. Select foods with a lower water content, such as dried fruit, bananas, nuts and seeds, potatoes, peas, and corn."
