I just came across this amazing video. On the one hand it is kind of kitschy and gimmicky. But I think it has some valuable lessons people for starting out.
A fit personal trainer eats poorly for 6 months and doesn't exercise. An not super outrageously bad by current standards for many.
In any event I think it was important he found out you can be eating lots of calories but still literally 'starving'. Modern food so devoid of nutrients body is hungry an hour later.
Good lessons about the power of whole, fresh foods. It's a lifestyle not a diet. Yes we preach that but pretty powerful coming from him. And the goal is health not scale weight per se.
He also found he did get 'addicted' and had withdraw from Mountain Dew in particular.
Well done video overall, worth a watch.
