That was pretty Mich the advice given, yes.
Thats like stuff all food 
Yeah really Iām 28 and Iāve done several cuts (between 30 and 5 kilos) and unless you want to be in laser-like optimized composition (like 10% and lower while keeping as much muscle as possible) thereās no point in counting everything. Just change your diet to a more healthy one. Especially when youāre young. Stop eating so much crap.
