I weighed 260, once at 5' 7". My favorite diet was to eat nothing but fresh fruit, and frozen, or fresh vegetables. You could eat all you want, and the weight will fall off. Don't add salt or fat into anything. Stay away from potatoes, carrots, rice, avacadoes, and bananas, for awhile. Some turn to sugar, and some have to much fat.
I'd cook up a package of frozen, mixed, vegetables, and put Fleishmans salt free margarine, on them. keep dry toast, with the margarine, and a little honey for something sweet, Desert, could be all the watermelon, cantalope , strawberries, or any other that you could fill up on. Mix the fruit together, for a nice fruit salad. Hope that helps. I lost 60 lbs. in 3 months, that away. Plus it's very healthy.
For protein, eat different kinds of beans. Or a piece of grilled chicken breast.
