Depends on what you are looking for , Surgery or Diet and Excersise.
If you are looking for the latter i have a recommendation.
There is a Doctor Nutrition that has a center here in Santo Domingo Dr. Rivas. He charges 5,000.00 for a 3 month plan . He will evaluate you and give you a list of food and how to eat. The good thing about him is that he sells food a la Nutrasystem or other in the USA. You don't need to buy the food from him but if you plan it right you can buy your food from him and make sure you stay on the diet. He sells food and treats.
You visit him once week to keep up your progress in those 3 months , etc.
Weight loss is an up hill battle , believe me i know. But if you put the work and set your goals as short a possible, it's all possible.
After the initial weight loss , Walk, Jog , Run, what erver but work out ....
Hope this helps
