As already said, the dreaded plateau comes to us all eventually. So far I have been on Xen for 3 months and lost every week, even if it's just a pound. I regularly review my calorie allowance on mfp, and have adjusted it down as I've lost the weight. I think uping exercise should help too. Everyone is different, so it will be trial and error to find what works best for yourself. My mfp was set to lose 1lb a week. I started with an allowance around 1500cals which has dropped to 1330cals as I've lost weight. I've always lost at least 1lb a weeks, sometimes 2, 3, or even 4lbs. Some people have found setting their mfp to 2lbs per week seemed to slow their weightloss rather than speed it up. I'd be more likely to feel hungry and struggle at that setting. Others have had great success at that level. Mix things up abit, see what happens
