Well i am a 27 year old dude thats 178cm / 5''10 and my weight is 55kg / 121,2 lbs and would like to gain another 15 kg for my 70kg total goal.
I would also like to become more flexible especially with my legs, since i have knee and feet pains in the joins, or rather it rarely hurts but mostly makes crackling noices.
My food habits for a week is pretty poor, i mostly eat pizza 3 days a week with the others being kebab / burgers for lunch.
In mornings i eat 1 Litre yogurt and some other good for stomach thing.
my late evening snack is sandwiches! i do those french looking long ones with a ton of butter and cheese and sometimes ham, i like those alot.
i use up a large cheese (1kg 28%) and a (0.6kg 70%) butter pack in less than 14 days.
I also dring loads of coca cola like 1 - 2 litre a day depending on temp outside and work load.
and i also drink pear juice to, like 1 litre a day.
What am i doing wrong and what can i improve to gain weight?
PS, i never ever get hungry even if sometimes can go without food for days. its like i don't have that feeling.
