Lets invent a diet based around appetite suppression. Lots of bitter foods and other things that make a person not want to eat coupled with foods that have a high caloric density. I've never heard of something like this before, but I think it's a very good idea. Here's my first draft.

Breakfast:
Yogurt, walnuts and green tea

Lunch:
Bone broth with ginger and tomatoes, salmon, more green tea.

Dinner:
Rhubarb Salad, squid, mashed potatoes with mint, hibiscus tea.

Snack if hungry:
A banana, more walnuts, water.
