People mistakenly think they should not eat to lose weight… starve themselves in the morning… then pig out at night.
I eat oatmeal every day (whole grains are healthy), but not instant oatmeal. I add protein powder (an egg can do for others) – protein satisfies longer. Skim milk, cocoa powder, cinnamon, and a teaspoon of dried fruit (cherries for me; no added sugar; read labels) round things out. Be careful of yogurt – most has tons of sugar added to the “fruit” at the bottom. Agave sweetener is just fructose, and is not recommended. I use cinnamon and cocoa for flavor instead.
