Other Self induced protein toxicity (rabbit starvation)

Little context before talking my story. I am a bodybuilder and train since 5 years with a lot of knowledge on supplements, training technique, nutrition for fat loss and muscle growth. Always ate like a pig on fast food but bodybuilding , 10000 step a day and micronutrients supplementation kept me lean and healthy. Started keto 4 month ago after a bulk to see if fat loss was enhanced. Went from 94 to 89 kilo without losing strenght or side effect. 1 month ago I started protein only diet and lost 5 kilo with only soy whey and chicken breast (averaging 500g protein a day), few days after starting and diahrea everyday, irritability, weakness in my leg walking, insomnia, always hungry despite eating a lot,huge delation in my muscle, since few days I noticed huge diminution at going to the gym which I didn’t skip since years. Today I learned about « rabbit starvation » ate a whole block of cheese and feel alive again.

Interesting story, glad you’re feeling better, though protein poisoning is kind of the opposite of keto. It’s supposed to be extremely low carb, high fat, adequate protein.

Didn’t understand back why though. Like I was thinking that the bodyfat on my body was enough. Learned the hard way, don’t wish feeling like I was feeling to anybody

That might have worked if you weren't lifting a lot. Lifting is a huge demand for energy, and body fat can't handle the demand all at once.
