I think the success we have with low carb or any weight loss venture depends on a lot of factors. Childhood obesity/overweight usually implies the factors are more complex or numerous than they are for most people and therefore it will be harder for you to overcome. It can be done, it just means you have to try a little harder because there is more work needed.

I think my weight problem was 70% physical and 30% emotional. The physical stuff is easy to fix - get insulin and blood sugars under control, eat low carb, no problem. The emotional stuff is much more challenging.
