The Endo/Ecto/Meso shit is not scientifically backed and is bullshit. Genetics only dictate where your fat is stored and your general body shape, but anyone can have a healthy BMI.   Yeah, life is unfair. I fucking love to cook and eat. If I don't count calories and monitor my diet then I gain past where I want to be. So I track and count my calories and have for years and will probably do so forever. Maybe other people maintain my size without trying and don't want to eat every snack in their home, but that's not me and has no bearing on my body or my choices.
