Metformin: can suppress appetite and even cause nausea in some patients. There are better things to eat than smoothies. Your pain medication and psychiatric problems can also lead to poor appetite. Discuss w/your doctor.

Why on metformin?: You don't say why you are on metformin. The med causes mild appetite suppression and weight loss promotion in most people who take it. I have had some patients who developed nausea that decreased appetite more substantially, but this is uncommon.
Dr. Richard Zimon
Internal Medicine 59 years experience
Not to worry!: Metformin usually does not interfere with appetite although all oral sugar lowering medications can have stomach (GI) side effects. Try taking it AFTER meal(s) Weight loss due to poor appetite is not a good idea so consult with your Primay Care doc if continues

Moderate intensity: All children should be engaged in moderate to high intensity exercise for at least 1 hour of every day. Any exercise your 11 year old will participate in regularly is the best for him. Make sure it is something that keeps his heart rate going. While exercise promotes health and helps in weight loss, it is not enough without improved diet. Check out choosemyplate.Gov for nutritional guidance.

Do detox diets really work for weight loss?

No: The only thing that works for weight loss in the long term is eating less and being more physically active. Making temporary changes and then going back to usual eating habits will result in gaining back the weight you lost. Check out this site to learn about fad diets: http://www.Eatright.Org/public/.
