He provides you with a spreadsheet to record the data, and using your data from the first 3 days, it helps you find when it's time to eat (based on your BG which tracks your personal hunger threshold). After that you check your BG just before meal time, and if it's higher than your hunger threshold, you wait until it becomes within the threshold before eating. This trains your body to know when you're truly hungry and helps to lower both personal hunger and personal fat thresholds. Several people on this forum have participated in the DDF Challenge and have had excellent results. The next DDF challenge starts on March 6.

One of the reasons I like Marty Kendall is that he uses Ted Naiman's P:E Diet approach to achieving better health. It's a very analytical approach to nutrition that emphasizes increased healthy protein, healthy vegetables and micro-nutrients, a reduced emphasis on fats (in other words, keto with a realistic approach), and elimination of unhealthy manufactured fats from seeds. Increasing my protein consumption and reducing my fat consumption to only what rides with the foods I eat a couple years ago helped me tremendously.
