Exactly.
It's like taking diet advice from Ronnie Coleman. Yeah you can cover everything in sugary sauce and those 150g protein shakes are easy on the stomach
Nothing to do with Sas but just in general. There are some guys who are genetic elites but they are also known for being able to grow lean and they have "super metabolisms" and none of that is untrue. Although sometimes you hear that then you find out they are using tren all off season, taking 10-20iu HGH, taking t3/t4 all year etc etc. I remember Nathan DeAsha going on about his metabolism all the time years ago and it's just his genetics and that's why he stays fairly lean in the offseason and again none of that is untrue. However he suddenly mentioned in a podcast he had been on at least 400mg (I think it was 400mg) of tren per week for years non stop and he never went off it ever. A lot of guys do shit like that. There are guys telling people they find it easy to stay lean whilst high dosing t3 with huge amounts of AAS and never coming off blast doses.
I would consider myself to have shit genetics for bodybuilding as in competing but I am naturally lean and have a fast metabolism so for looking athletic on a beach I am good. The term "ectomorphic" could be used and for me if I combine high fats with higher carbs I get fat and fast. Whenever I do daily granola (I love the taste) I do great for a short time then it's downhill from there. Now if I was on 400mg tren the entire time and maybe I could throw in some t3 etc then sure that could be different. Even so I don't do good with higher fats with carbs even if calories are similar to doing very high carbs. My digestion usually takes a hit and I always end up more bloated and thick waisted within a few weeks/months.
