Orientation session scheduled at Providence
Went through TWH in 2011. I think all sites are similar. they want to make sure you are making positive changes. Cutting out the junk food, soda, alcohol. You want to work towards 3 healthy meals and snacks. Decrease carbs and fat.
Easiest is to to strat tracking what you eat.
As well what diet plans you have tried etc...
Good luck in your journey
