How do you retain any sort of muscle at 1800 calories and 140g of protein? It seems like for your size you should be almost doubling your calories and getting in 200g of protein a day. I'm 175 and the only way I can make any sorts of gains is at least 3200 calories with around 190g of protein per day. I've started training hard this year and so far I've gained 20 pounds since the end of the summer while lowering my body fat.
