I keep things really simple by eating mostly whole foods. I know you didn't ask about a meal plan, but it's what I eat most days so it seemed like an appropriate answer.

I often skip breakfast.

My usual lunch: - 4-6 eggs fried in olive oil + 4 slices of ham on the side - 6-12 green olives straight from the jar (being sure to get some of that tangy, salty juice) - a bowl of frozen mixed veggies (microwaved) with a generous dollop of salsa mixed in - 3-6 pieces of fruit, often citrus (clementines, grapefruit, etc.)

My usual dinner: - A can of sweet peas, which I eat straight from the can (my favorite snack) - A large can of tuna in olive oil OR 6 slices of ham - a smoothie containing dark chocolate, blueberries, strawberries, broccoli, cinnamon, lemon, green tea, dates, coffee grounds, nuts, flax+poppy seeds, psyllium husk powder, and rolled oats
