This drug in a nutshell partially paralyzes the stomach and upper intestine causing food to move through slowly. This has the effect of reducing food cravings as you literally stay full longer.
However slowing down the stomach muscles has many risks and many side effects.
Yes this drug is great for people who have struggled with weight loss and may not realistically be in a position to work on diet and exercise.
However this drug is not a substitute for the larger issue at hand. Many (possibly most) Americans are not living healthy lives in terms of mind, body (maybe spirit).
Improving physical activity leveled.. learning to eat less and to eat healthy should be a national priority. If anything the US government lack of addressing the elephant in the room and the underlying cause of many of these metabolic orders should outrage all Americans.
Just my two cents
