When I lived in Orange County ,one of the diets I did on my own was weird, but it worked for me for awhile. I worked at a Car Dealership in Santa Ana. I would go to the Sunkist packing shed and buy Naval oranges by the case. I would eat oranges all day at work, would run up and down stairs, and drink about 10 to 15 cups of coffee in the 10 hours I was at work. I had lots of energy and lost about 40lbs in 3 months. I would have a normal dinner, including pizza, steaks, pasta, etc.
Don't try this at home
