Firstly, I need to correct the author on TAG. One person's jaunt into a 30% caloric deficit for 10 weeks while still eating veggies, protein shakes, and multivitamins. The gist is, eating too much healthy food is not necessarily healthy and eating crap, just a lot less, can improve health parameters but the longterm is iffy. I posit that most Americans should lose 10% bodweight ASAP to improve health parameters and I fully agree with Shizzo that discipline, willpower, whatever you want to call it is at the heart of the matter. How is that taught or expanded or gifted or bequeathed? As to the study, it raises great questions and I would if liked to see a quality of life pre/post test questionnaire performed by the professor. Also, if he used TA's stuff in the class then that is cool.
