Despite the title's bold claim, the article isn't very informative; it really feels like a puff piece for these pharma companies.
One thing that I think is underacknowledged in discussions of weight/fat loss is time horizon. Fad diets don't work. You can't expect to lose 30 lbs in 2 months. Set a longer time horizon. What do you want to weigh in a year (or more)? Reduce your calorie intake gradually. Weigh yourself often. Are you making progress? If not, lower your calories a litle bit more. Keep trying. Try to eat healthy foods, but there's nothing wrong with some "unhealthy" foods. Try to be active and exercise, but you don't need to be a marathon runner or powerlifter. Be fair to yourself. You gained the weight over time, so now you have to lose it over time.
