To me, 1300 calories a day sounds like too little for even a slightly active person. Maybe you guys are starving yourselves too much and slowing down your metabolism.

As stated above - if you eat too little your body becomes even more efficient at storing every little calorie as fat, and then - as soon as you start eating even a bit more normally your body will gain lots of weight because it never knows when you're going to be starving again.

Maybe talk to a nutritionist, for even one session. As a nurse, and as someone who is trying to lose weight, cutting back to 1500-1700 Calories a day plus adding some walking has dropped almost 10 pounds of fat since Xmas, and summer's not even here yet.
