Honestly. I read all about gravity suits, energy and heat, krispy cremes and I'm just struggling to find out why it needs to be so confusing.
The Tony Principles:
Bulk: Eat more than you expend
Cut: Eat less
Stay away from saturated fats and refined sugars. Fat has more calories per gram than protein, carbs and alcohol. Smoking is gross.
Most of all...IF IT AINT BROKE, DONT FIX IT.
