Calorie and carb counting don't work for most people. Just look around at the many who have tried it and gained everything back.
Portion control. Ditto.
"Diet" foods contain artificial sweeteners and chemical additives that often make people look fatter and puffier than before. See here.
No balanced meals. When your body is out of balance, e.g. obese, an imbalanced approach to weight loss is quickest. Temporary, yes, but imbalanced. Like a plane revving up to take off. The initial effort is massive but short, until it lifts off and goes on cruise control. Imbalanced is like that. Balanced diet programs, research shows, have a 50% lower likelihood of weight loss.
No rabbit food required. Although they have vitamins and minerals and water and fiber, they don't accelerate fat burning and can even interfere with it.

P.S. ER opens August 4. ER starts September 6 (4-5 week personalized-to-you program) ER is really expensive. 15 Active Participants. 30 Auditors.
