Hello. Lately, every night before I slept, I felt very hungry. It use to be solved by just eating a piece of bread. But now, I ate a very big serving for dinner and is still hungry before I slept, even toasting some bread wouldn't help. Not just in the evening, now, when I wake up, afternoon, I feel the exact same thing. I am always really hungry. I worried that I have parasites in my stomach, and my metabolism is very high. I'm not even gaining any weight!! How can I solve this problem? Or prevent it from happening? Also, keep in mind I am a very active athelete and is exercising every day.
