About a month ago I posted about a new study showing that resistant starch, rather than lead to weight loss, per se, instead leads to important fat loss and lean gains, which could even be growth of colon tissue and a bloom in the population of microbiota which are part of your lean mass.
[...] these data provide convincing evidence that the gut microbiome can play a crucial role in the absorption and use of dietary nutrients as well as exhorting a strong influence the development of obesity. [...]
[...] there is strong evidence that RS lowers whole-body and visceral adiposity. The magnitude of these changes in adiposity are very large and sufficient to independently improve insulin sensitivity, and reduce the risk of diabetes, CVD, and certain cancers.
At the same time, lots of folks were reporting in comments that while they had not lost much if any weight (some have; and I have), and some had evan gained, they nonetheless reported things like a leaner face and neck, and better fitting pants.
Well beyond the anecdotes, I now have a bit over a month's worth of data from a reader that I tossed into a chart. The reader writes:
I've been taking 4T of potato starch since late January. I experienced the shift in appetite (not nearly as hungry all of the time), but little else, well, except the fartage. In 6 weeks, there was no reduction in either volume or stench. The whole time, I was peeling paint with the stink. Then I saw your post on adding the probiotics to the mix, so I ordered all 3 mentioned.
They showed up March 1st and I started adding them, along with Banana Flour and FOS to my morning smoothie. It seems that one of those probiotics added whatever was necessary to tame the fartage. In the last 2 weeks, I've finally gone through the cycle others described of the reduction in stink and volume.
More interestingly, my body fat measuring scale is reporting a trend worth sharing. Prior to Feb, the weight and body fat composition had remained relatively stable for several months (much to my disappointment). But, the bugs (and I haven't changed anything else I can tell over the last 2 weeks) are seriously doing something. There was a slight trend toward improvement before the probiotic, but it took off quickly once I added them.
Just thought I'd share. Looking forward to the book.
So this is pretty dammed interesting, wouldn't you say? Some observations:
- About a 10 pound overall weight gain in 5 weeks.
- An overall 6% reduction in body fat percentage in the same period (I don't really know about those scale measuring devices in terms of accuracy, but it's the relative numbers that matter and in this case, they're very linear).
- Notice the 10-pound drop and rebound—about a pound per day on average—and that it began right when he began taking the probiotics.
All very interesting. Does anyone still have any doubt that the gut biome, and its proper care and feeding, have a profound impact on overall body composition? I suspect that in the long run with plain sensible eating, weight will stabilize or maybe even drop, along with a steady decrease in fat mass down to more human levels of 20ish percent. We'll see. Keep the reports coming and if you have it in you to record data like this, all the better.
