Indeed, today I went biking again, did a bit more than last time but still not as before. I feel much more energy in the beginning but then after around 40minutes I start to feel tired. But I feel I have more tonus now, maybe it's placebo maybe not.

I was unknowingly almost vegetarian, before going carnivore

I'm so glad to hear it! 

I'm so accustomed to the improvements that I've had with carnivore that it's like white noise to me, and I don't necessarily appreciate it as much. So it's always great to hear from others who have had good results.

There's definitely a HUGE adaptation period at the very beginning, if you go "cold turkey", i.e. start carnivore from one day to the next. It's called "keto flu". I didn't have it because I transitioned slowly, but I know people who had it, very strongly.

In terms of athletic performance, apparently people do recover and SURPASS their athletic performance, after going carnivore. But your body takes a while to adapt, sometimes even months. 

Dr. Anthony Chaffee (Plant Free MD podcast) has lots of interviews with carnivore athletes, and goes into detail on this.
