First congratulations are in order on your initial weight loss. Second after losing such a large amount, and 15lbs in 2 weeks is large, it's normal for the body to take a break & readjust before losing more. You also may be losing inches instead of pounds. In addition to using your scale to gauge weight loss use a measuring tape too. Measure hips, waist, thighs, etc.. You may be quite surprised to see your measurements decreasing while the scales says nothing's changing. Be sure you're getting at least 64oz of pure water daily too, otherwise you may be retaining water weight. When did you add the shakes & bars? Some people are stalled by the bars, as they contain sugar acohols. I'm not stalled by shakes or bars, but they could be your problem- only you can tell. If they're a recent addition & you started stalling right after adding them, then try eliminating them for a while. You also might want to consider replacing you 1/2 & 1/2 with heavy cream, less carbs & more fat- which is good. Sometimes we foget how important high fat ratio is with this WOE. Most importantly be patient & stick with it. You will lose again. Remember you didn't gain all the weight overnight, nor will you lose it all overnight. Weight loss for me goes in spurts several pounds a week then a break for a week or two. Try not to get discouraged. Good luck.
God Bless,
