I have been stuck in a weight range for quite some time now. The day before my double red donation I was at 201. I took it easy after donation and the next day did a little work at mother in laws nothing strenous just some drywall stuff. I only did cardio twice this week, lifted minimally the other 2 days. I got on the scale yesterday (same one) 6 days after donation and I'm down to 190. My diet does not vary much, low carb, low fat high protien. I did have some box cereal one day that was definitely not low carb, frosted mini wheats,man I forgot how good sugar tastes. Could it be the double red donation?
