I know that Farah like to have his athletes use more carbs.He must have them using insulin.
Insulin gives you and ugly look.You can tell some one who uses insulin and someone who doesnt.
They got a softer look 90% of the time.
When it comes to gurus, I think Chris Aceto is the most consistant.Hany is hit or miss.If he likes you or you get him alot of publlicity.You will do well.If you just one of his regulars.Its hot or miss.
Chad is pretty good.Art Atwood was pretty good to, may he rest in peace.He would make his athletes suffer.Diet really hard, but they looked good.
I think zig zagging the carbs works best for naturals and not naturals.On your low carb days protein has to be really high, and you got to use good fats.Like red meat natural peanut butter, flax, CLA etc etc.On your higher carb days to replensih glycogen keep fat low, and protein not that has aswell.
This way glycogen gets back into the muscles.
A good way to see if your body is in homeostasis is check your body temperature.If your temperature drops below 97 degress you need to up your calories or cut back on the cardio
When the body temperature drops to low that means the body wont burn fat.
You can use a ear thermometer/.It only takes a few seconds.A natural bodybuilder should monitor his body temp 1-2 times per day/
