Hello

Hi Sarah. My only advice is to start learning about ways that might help you from doctors that are experts. Dr Jason Fung and Dr Ben Bickman are two that I follow- easy to find on you tube and both have books out. Dr Fung is an obesity expert and if you are willing to follow his recommendations and the science behind it that Dr Bickman provides you will succeed. Dr Bickman podcast is called the metabolic classroom and Dr Fung is interviewed on a ton of podcasts. It's so much more than calories in and calories out. But starving yourself will backfire- trust me, been there many times. Exercises definitely helps but what you are eating has the biggest effect.

I wish you the best and hope you succeed!
