My guess is not very accurate. I’ve lost 63 lbs. over the last 4 months, so of course I notice a big difference in appearance. Weird thing is though, they’ll be stints of time (week or two) where I look leaner, but the number on the scale won’t budge. I don’t think it’s muscle because I only do cardio and pushups. I weight myself the same time every day (in the morning). Then all of a sudden, I’ll drop a few lbs. like nothing. That’s the way it’s been going for the last 4 months. Why is this? It’s discouraging because every time this happens I begin to think I’ll never lose another pound….even though I should know better than that by now. Still have 30 more lbs to go!
