From the weight you wrote, her weight and height are just below the 75th percentile for her age which indicates she is normal and not overweight (unless the weight is not correct). If you are concerned, suggest bringing your daughter to another MD to get her checked. It is recommend increasing children's physical activities (play, dance, sports) to lose weight, and not lower calorie intake due to the need of calories for growth. Limit time in front of the TV or non-active-video games. There have been studies showing the longer the length of time a child sit in front of the TV, the greater the weight gain. Limit high sugar drinks/snacks, and try replacing with low fat milk/yogurt or fruit/popcorn/low-fat cheese. Additional suggestions: cook only low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), fat free or low fat dairy products (skim milk, 1% milk, low fat cheese, low fat yogurts, low fat soy milk/yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits, salads, and vegetables. Eat daily high fiber breads and cereals (oatmeal) and limit ‘junk’ foods. If she has a constipation issue, suggest the above high fiber and using Benefiber which is natural and safe for children. Hoped this helped you.
