the biggest factor may be genetics -- not something that you can change unfortunately. it is still impossible to increase weight without eating more calories than you body needs to maintain weight so her diet may still need some adjustments. she may be sneaking in extra calories at night or at school. i worry about the "strict diet" comment. while i do not know her height and weight children are growing and must have sufficient calories for that. you don't want her to cry because she is hungry or develop a negative self-image about her weight. when she becomes a teenager these messages can backfire and you could end up with a bulimic child so be very very careful. keep an accurate food diary and see where you can trim. give her a huge salad and non-calorie drink before dinner and pace the speed of her eating. serve dinner on a plate (a small plate) and do not have leftovers. be more like a restaurant than an all-you-can-eat buffet. have low-calorie snacks (sugar free jello) apples etc. for dessert but make her wait an hour or so after dinner. involve the whole family. at her age losing a pound or so a month is a triumph. even if she stays the same this is progress. in a few years hormones are going to be playing a significant role and the strategies will change.
what can cause active children to be overweight. my 7 year old daughter is very active but is very overweight. we eat healthy balanced meals & don't snack in between meals. she has been tested for diabetes thyroid & has seen a dietician to no avail. she was put on a strict diet by the dietician & gained weight instead. help i want to help her lose the weight before it's too late.
