Alright, I'll preface this by explaining the I'm underweight and have been all my life. I'm what they call a "hard-gainer." I've been doing research and it seems that my problem is that I simply do not take in nearly enough calories to get any bulk going on. Well, I've really started to gorge on as many meals a day that I feel hungry for, and I am eating probably around 500 more calories a day than I was before. I'm not counting, but I'm probably getting around 2500-3000 calories a day. And I am weight lifting every other day or every few days depending on recovery times. The only problem is that I'm FARTING all day long! (This is a problem at work.) This can't be entirely healthy in the long term. Is my body having a hard time adjusting? I'm eating about 95% clean (occasional desserts), lots of protein, fruits and veggies, whole grain pancakes/oats, protein in the form of meat, fish, and dairy, no sups or powders. What am I doing wrong?
