Sugar burner is an injured metabolism? Bahahaha get real, you're out of your mind.
It takes a great deal of fighting and discomfort to become a "fat burner", it's unnatural, just let that soak in for a bit. Real healthy people don't have any issues with any macro-nutrient, there is no evolutionary proof or value of "fat burning". You didn't stumble upon an oasis of health, you just bit into another fad hook line and sinker.
Mentality is key to health, there is no 80/20 or 100 rule to that. Health isn't over analyzing every aspect of what you do in order to make sure you stay a "fat burner".
