Take a look at the size of your fist.... that's how big your stomach should be,...... if you're eating more than 2 fists worth then thats too much.......
Also as you're eating pretty unhealthy foods in stage one, you won't lose much anyway.... at stage 2 when you're eating paleo foods more should come off.
Cut down your portions for now but dont be despondant yet.... the weight WILL come off in stage 2
Best of luck
