I'm on day 2 of my third Whole30 in 8 months. In each of the previous two I have lost around 10 pounds. I weighed myself yesterday morning (no weigh-ins during a Whole30) and was surprised to find my weight down another 5 pounds. I think it resulted from no alcohol for a month while I was on a blood thinner after knee replacement surgery. The knee replacement, my second, is also permitting a degree of activity that was not possible due to the arthritis.
So the good news is my BMI is at 25 for the first time in 3 or 4 years. I don't necessarily want to lose a lot more weight but each Whole30 is helping me redesign my eating habits away from sugar and wheat (dairy was never a problem and I really do only drink in moderation). I see that as a good thing and if I lose another 5 or 10 in addition to the 25 I've lost in the last 8 months, that's okay too.
I was smart this time and kept the smaller waist size pants in a back closet. Pulling them out last week was as fun as buying them in the first place - and way cheaper.
