Ectomorphs are the people you typically hear walking around saying “It’s impossible for me to gain weight, I eat and nothing happens!” Well this is another typical gym myth, you could be eating what you think to be a lot, but not eating enough of the right things.
An ectomorph needs to really jump up the amount of complex carbohydrates they eat (whole grains) while minimizing the simple carbohydrates. Also your typical ectomorph can eat more HEALTHY fats than your typical person, things loaded with omega3 fatty acids (Natural PB, fish oils, etc). So if your an ectomorph who’s struggling to put on weight, just increase your carbohydrate intake every meal, and you should start to see results. Remember 6 meals a day is key in steady growth!
