Went from losing 3. 5 lbs a week for the last 3 weeks to gaining a pound and a half. Drank all my water this weekend and still doing intermittent fasting. As well as walking 6 miles a week. Just to be sure I wasn't under estimating, I added up my calories on my two "worst" eating days in my opinion. Including zero point foods, I didn't go over 1000 calories a day! I understand a plateau, but a pound and a half gain? Thoughts?
