Never heard of the T-factor, but I did obsess over fat until recently. I wasn't counting grams but I did obsess over percentage of fat in my diet. This came from having turned to veganism (which I love but don't push on others) and discovering a whole way of eating that focused on eating less than 10% of calories a day from fat. I used to put my menus in Cronometer and obsess if the total came up even 11% or 12% fat.
Thankfully, I came to my senses and realized that fat (especially good fat) isn't the enemy. I don't count fat percentages any more, though I do try to stick with fats that are considered healthier.
Holistic healthy living is not just about food and exercise - it's about the whole person, body, mind, and spirit
