Atkins Help :)

[SaraJaneQ]

Hi all - I was on the Cambridge diet and lost 16lb after 4 weeks. Although this diet made me really unwell so I swapped to Atkins.. I sadly haven't read the book but ordered it frm online and waiting for it. I started Atkins 3 weeks ago and have only lost 3lb so far. I have had a few slips but determined to get back on track once my book arrives. I regularly do my gym sessions alternating from cardio days and strength training as much as I can. I think I may have hit a plateu? My mid section isn't moving could people please advice?? Thanks so much xx
