Your diet actually sounds like the “get weak and crappy inside in all the places you cant see” diet. 50% carbs is NUTS. Your body never has a chance to burn anything but carbs, and if you dont burn all of them, they turn into fat. Carbs are the worst possible fuel for your body.
I also do 16:8 fasting, so I know I am burning through all my carbs and glycogen stores in my liver on a daily basis.
What I usually say when someone in person starts talking to me about their low carb diet vs my diet, is “look at me, look at you”. That usually shuts them right up.
Your last sentence in this message is ridiculous. Carbs are a great fuel for the body. Serious weightlifting can be greatly impacted negatively over time by lack of carbs. I definitely don’t recommend you go into a career as a trainer for weight lifters.
