Get Optimized!

  1. Reframe my thinking on fat. It isn’t just fat; it also functions like an endocrine organ, releasing hormones and is positively linked to brain size and several of my body’s systems.
  2. If my body fat percentage is too high, focus on losing just 7% of my body fat. This can improve my insulin sensitivity by 57%.
  3. Get tested for AD-36 if I have concerns about my weight. This virus can make it easier to gain weight and harder to lose it.
