I read that 25-35% of your diet should be comprised of fats. Does this apply to a bulking stage?
20 to 35% of your total calories is a good rule of thumb.
Why?
Happy hormones
Happy brain
Less sugar/day
fat-soluble vitamins are happy
Specific intakes are specific to each person. I personally go for 25 % as this seems to work best for me personally.
I do know a bunch of people that bulk on keto(high fat low carbs) but it's probably not the norm.
Life is one big experiment, try different intakes for a month at a time, see what works best for you.
