How would you change your food and beverage intake for tomorrow to meet the goal for your calorie intake? How about your physical activity level? How would you change this? I did so-so on the pyramid worksheet. I would try to balance out my meals so that I will consume adequate intake of food and beverage groups, to keep a healthy body and weight. My physical activity level would be increased to at least 60-90 minutes daily; meaning I would set aside time for this important activity. [Show More]
