Barbershops have always been a profitable industry, selling services, technology and time, all of which don't need money. It is not recommended to only open a weight-loss shop, because the project is relatively simple and the profit point is small, so you should not make much money. And the customer object is relatively single. I suggest you open a comprehensive beauty salon. You can have a weight loss project, and take the weight loss project as a groundbreaking drainage project. Customers can lose weight in your store, and they can also do facial care and body care projects to increase the items in the store, so that there are more profit points and the customers' repurchase rate is high.
