Slow metabolisers like me burn fat at say 95 degrees. Fast metabolisers have metabolic rates way over the 100 degree limit. Their thermostats are stuck at say 102. They can burn NO fat because they re too hot. That s why the most obese people on the planet are stuck at the fast 1 level.
Complex carbohydrates make their metabolic rates soar, exacerbating their weight problems.
No pasta for them. Fast or slow denote specific endocrine patterns. Your endocrine glands produce hormones that control all your body functions. This includes everything from how you lose weight to how you lose your temper. How you eat influences the production of these hormones.
