It's not that easy, brother.
I used to spend tons of money in the best food I could get ahold of. Expensive restaurants, best imported ingredients, etc.
I was still obese. There were underlying issues, diseases and habits that made me obese, it wasn't the food.
The solution was to walk one hour a day, every day, no matter the consequences. And taking care of the other issues as well, of course. Saying that it was hard is an understatement.
