I'm doing the Ideal Protein protocol, I've lost almost 50 lbs in 5 months and have hit a wall, only losing about 5 lbs in the last month, trying to motivate and get back on track!!
Suggestions.........

That's awesome about your weight loss already
Don't be bummed about the smaller weight loss last month...as we get closer to goal, weight loss slows. As long as the scale is continuing to move down, you're in great shape!!
