I've never believed that whole gluten-free story for a minute. I think he went to a different kind of doctor and got some "help".
if you don't know what being a celiac and ingesting gluten can do to you then you have noooo idea what novak went through.
my tennis coach is a celiac, when he was diagnosed he gained 50 pounds in 5 months after changing his diet.
not being sick 24/7 makes a huge change in your life
its like having asthma, lets say you breathe and get about 80% of the oxygen normal people get.
If you overcompensate with training to breathe at the same rate as a normal person then when you start asthma medication your oxygen intake is increased drastically.
Im using the asthma example because that is what i went through, novak overcompensated for the lethargy and nausea with training hard and even harder when he started to feel sick.
thats why he was so dominant in 2011, he was playing with a fitness level that was head and shoulders over everyone else, because he didnt have the illness bothering him after that, the reason he isnt the same as then is because once he was healthy, his body didnt need to overcompensate to reach a good level of fitness.
when i had a blood test ,before starting asthma medication, i had extremely high concentration of red blood cells and hemoglobin. when i started my asthma medication i felt superhuman, but over the course of about 5 months my fitness declined because the elevated levels were not needed, and came down to normal.
Now i am fitter than ever and healthier than ever, but only if i exclude that period of time when i had elevated levels of red blood cells and hemoglobin.
Novak was like that especially early 2011, towards the end we saw his fitness go down a tad and his fitness levels found equillibrium.
