I used to get really hungry, but, around 5 years ago, I changed my diet. Stopped eating grains and legumes, substituted them with vegetables and tubers.

I now surprise many people with how little I eat. Today, for example, I had my first meal at 14:00 and I was awake from 6:30. I just wasn't hungry. (I did have a coffee though)

It is convenient to not have to constantly eat.
