I've been with Noom for five weeks, and I've lost 13 pounds. I find it extremely helpful to check in with Noom every morning. They provide psychological help, explanations about nutrition, goal setting, and connection to other Noomers.
The eating advice Noom gives is helpful, but I find that I do best when I pay attention to reducing carbohydrates. Their emphasis is more on calorie density and total calories. They do helpfully recommend eating fruits and vegetables.
Bottom Line: Yes, I would recommend this to a friend
