* You're strategy is vague and difficult to determine compliance. How much is a "decent amount"?
* My method is quantitative. Everything I ate had a number, and that number totaled less than 15 by the end of the day.
The problem I have with your method is the idea that I need to have a huge knowledge-base to make it work. How many people do you think know if their butter is "grass-fed"? If I go to Applebees, the calorie number is listed right on the menu, yet I would never be able to find out if their butter is grass-fed.
I put off trying to lose weight for years because I thought I needed to read 10 books to figure out how. Turns out all I needed was a calculator.
