Hi. I’m underweight. I’m 26, 6 foot and weigh 128 pounds. I am desperate to put on weight. I have been training with weights three times a week, twice with a personal trainer for a year. Doing a mix of strength and stamina. No cardio at all. I’m eating so much I’m nauseous most of the time. I’m taking protein supplements, creatine, gainer shakes. Eating lots of protein and carbs. About 50:50. I’m getting 2500 – 3000 calories a day most days. Sometimes I get so sick I can only manage 2000. I am basically eating as much as my stomach will allow. I’m definitely eating a lot more than when I started training. But after a year I haven’t put on any weight. The most I got to was 131.6 pounds at a massive push and it came strait back off after a week. The strange thing is I’m definitely getting substantially stronger. My trainer has assured me that my rate of strength gain is normal, if not above average. How can this be? What is wrong with me?
