thanks, brother.
more important, its to follow it, just listening and then not doing as said wont go places 
prime muscle, theres no ecto endo meso morfs, other than structure.
their metablosim rates are all within few %.
there is not ppl who can get away with eating everything and not get ft, and there is not ppl who get fat just by looking at food.
theres only ppl who overeat, ppl with small stomachs, ppl with more efficient metabolism bc of being more active.
a baby has very small stomach, it cant eat so much.ectomorfs have small frame with bit smaller stomach, etc.
force feed ectomorf with 10k cals a day for a while and see how he gets away with eating anything.
starve an alleged endomoirf and see how he cant lose weight.
in the concentration camps,i bet the jewish were all mixes of morfs, and the survivors all came shredded.
conclusion, sciene says theres different bodytypes but they only mean bone structure, not metaboism.
ofc a mesomorf structure will look more muscular than a wide hipped turd endomorfic one.by default.
Perhaps you know more about the science of genetic body types then I do. What I know from personal experience is that both my parents were extremely thin. My dad was 6'6" and when he enlisted in the military as a young man he only weighed a little over 165 lbs. A few years later, when he met my mom he was up to 175 lbs. He had big bones. My mom was a rail. She was 5'8" tall. The most she ever weighed was 129 when she was 29 years old. Most of her life she weighed around 120 lbs. She would have been considered medium to large boned. When I was 16 and stood nearly 6', I weighed 126 lbs. My wrists measure 9". I believe I am big boned. Our family doctor prescribed D-bol and testosterone shots to help me put on some size back then. I managed to get up to 144 lbs. over the course of a year. Maybe I am not an ectomorph genetically, but it sure felt like it and I sure looked something like the examples normally shown of this body type.
You are right in that we inherit more than just bone structure. We inherit to some degree our parents' metabolisms. Many kids learn eating habits from their parents. Mine ate healthy and in small quantities compared to what you see folks eating today. Also, junk food was not common in my childhood home. Instead, there was always a bowl of fresh fruit on the kitchen table. Since I was an only child my mom did not fix meals "family style" rather we each got a portion on our plate with no seconds available. Deserts were reserved for special occasions only. When I was in elementary school, my mom packed my lunch. It is safe to say, I got a good start from my parents as far as eating habits goes.
I mentioned that I weigh over 200 lbs. these days. This did not come naturally. I started working out with weights in my teens. As I mentioned, I did some cycles of then legal anabolic steroids as prescribed by my parent's physician. Over the years, whenever I'd slack off on the weight training, I would lose weight. My weight as an adult has been all over the map. I have weighed as little as 155 lbs. and as much as 225 lbs. The latter being when I was taking D-bol in my late 20's and working out almost daily. The former when I was not working out and not on any AS or supplements. Currently, because of low testosterone, I am injecting 200 mg of test cyp every other week. This is also with a doctor's prescription.
I am not cut or ripped. I also am not fat. I feel good about how I look. I am healthier and more fit then most guys I see walking around who are senior citizens like me. If I were to live the rest of my life in this condition, that would be great with me. It matters not whether I am an ecto, endo or meso bodytype.
