Weight loss ; jeans: First off is your weight loss intentional? Easiest answer is new jeans or tighter belt. If weight loss is unintentional and your are not sick or with a chronic illness...This is a simple question of what goes in must go out or you get fat. Increase your caloric intake to match your energy expenditures. Use a balanced approach with good quality rather than just increasing calories.
