hello, I'm new to bodybuilding and this message board,after reading other posts it seems like there's alot of you that know your stuff,i don't, hoping someone will take the time to read and help me out. I'm 5ft9 and 155lbs. I have good muscle tone as i've been cutting lawns this summer and work hard but would like to be less cut and a little thicker.The only thing i do understand is that i must take in more calories than i burn.i'm not even sure how many calories i should be taking in. I have a very fast metab. very fast.my bodyfat is nexted to nothing,i'm guessing i need around 5 thousand calories or so a day(really have no idea). for the past 3 weeks i've been taking several meals to work.I also bought meal replacements and weight gainer.Problem is that I struggle to get these meals down my throat,by late afternoon,it takes everything in me and a whole bottle of water just to swallow a tunafish sandwhich snack after eating four previous meals ealier not including my shakes. I also feel bloated and tired when I work,i want to sleep all the time.Then i have to come home after work and eat even more. Is this the price i must pay to gain weight? is everyone else trying to gain weight going through this sluggish feeling?Are my meals unbalanced? What I'm doing doesn't seem right.Eating has become a nightmare for me,it's like my body doesn't want me to eat anymore,is it really healthy to literaly force the food? I'ts only been 3 weeks,is my body just adjusting or will it always be this way? I now have mad respect for those who can eat 6-7 meals a day,mabye I'm just being a bitch,I don't know, I never thought it would be this hard to eat this much. I'm also lifting as heavy a weight as I can with good form when i workout with low reps.Not even sure if this is right,frustrating diving into something you know nothing about,thanks for reading,any advice or encouragement would be greatly appreciated. Can post exactly what I'm eating in another post if anyone wants to seriously help me. My meals must be unbalanced. Doesn't seem right to be sluggish like this.
