My 11 yo son wasn't seriously overweight, but pretty pudgy and soft as he never exercises much. I put him on the maintenance level of Somersizing. He has mostly given up high glycemic value foods that she terms "funky." He eats whole grains. I make meals that are primarly protein and veggies and he is allowed to add a small amount of carb. He still eats real pizza on occasion and other junk kids eat, but I'm teaching him to make choices that are healthier---if he wants to eat pizza he should have water, not soda. A little real ice cream after dinner is okay, but forgo the bread at that meal. I have him eat fruit on an empty stomach as well as junk like halloween candy. That way it's not mixed with as much other stuff to get stored as fat. His weight has stablilized and he has trimmed down. Sadly, he still needs muscle tone and we don't seem to be able to build any, even with his little workout he does.
