No one diet in particular. I like some of the ideas from the Paleo diet, but also try to listen to my body. If I am hungry for simple, plain foods, that is what I eat. I also make quite a few richer, fattier meals.
Always high in protein, smaller amount of carbs, and several vegetable servings with each meal.
I keep onions and garlic on hand. Onions can be chopped and kept frozen. Garlic keeps for quite a while in the fridge. I use both almost every day.
I try to keep it simple with only a few high quality ingredients.
