there must be something happening to make your loss this small , have you drunk enough water ? are you constipated ? were you on a low carb diet before you started this ? are you 100% sure you have been 100% on plan ??
Looking back on your other posts it looks like you moved to Exante from CD so actually 2lbs is ok. Its not like youre going to get the big week one loss. Everyone on a VLCD gets weeks where they sts or lose 1 or 2lbs its perfectly normal. Youll probably make up for it next week.
