As part of a healthy diet, eat plenty of fruits and vegetables, fiber-rich whole grains, fish (preferably oily fish-at least twice per week), nuts, legumes and seeds and try eating some meals without meat. Select lower fat dairy products and poultry (skinless). Limit salt, sugar and sugar-sweetened beverages and red meat.
You can slowly work up to at least 2½ hours (150 minutes) of moderate-intensity aerobic physical activity (e.g., brisk walking) every week or 1 hour and 15 minutes (75 minutes) of vigorous intensity aerobic physical activity (e.g., jogging, running) or a combination of both every week.
Additionally, on 2 or more days a week you need muscle-strengthening activities that work all major muscle groups (legs, hips, back, abdomen, chest shoulders, and arms). Children should get at least 60 minutes of activity every day. Just an "active" thought.
