ProLon Day 5

Oct 13, 2019

Today’s the last day of my ProLon Fasting Mimicking Diet. I wrote about my start in a post titled ProLon Day 1. I was a little nervous about trying this so I figured I’d blog about it to bust through any anxiety I was having about trying it.

I find myself very happy with it on Day 5. I’m not hungry and have only had a few stretches where I was hungry, and I think most of them were a result of someone (where 50% of the time that someone was Amy) saying “Are you hungry?” which then caused me to think about it.

The quantitative impact of it is pretty dramatic. My side by side weigh-in data (pre and post) is:

I generally only weigh myself once a week (usually on Saturday or Sunday morning). I don’t expect the weight loss to persist at the same level (e.g. I expect it’ll go back up a little when I start eating again). I haven’t run in the past five days (I took last week off) and am surprised that most of the weight that I lost was Skeletal Muscle Mass. And, it’s even more fascinating that my Body Fat Mass actually increased in the last week. I’m not really sure what to make of any of that, but my measurement in a week will be interesting.

If I was judging this only on weight loss, it would be a win. By seeing the type of weight I lost by doing the diet but not exercising, it feels like it wasn’t a win. But that’s perplexing to me so I’m interested in the next measurement a week from now.

But ProLon is about a number of other things besides just weight loss. I found their clinical trial data fascinating and their marketing summarizes it as:

Amy was right when she told me to get a bunch of blood work prior to starting ProLon and then do it again after I finished. I didn’t listen to her, which is usually a mistake on my part.

I’m going to try ProLon again in a month (they recommend you do it twice) and next time I’ll get my bloodwork done before and after.

In case you are wondering, my ultimate weight goal is 190. I’m 6’1″ and have a lot of lower body muscle mass from my running. It’s time to get down to 190 while working on both upper body muscle mass and flexibility.

I’m committed to that, although I’ve always had an extremely hard time with upper body exercise. If you’ve got any suggestions for a runner that hates going to the gym, loves to be alone, and has trouble getting into a weight lifting or yoga rhythm, I’m all ears.
