I like what you guys are saying, I was hoping some of you would chime in.
This potato fat buster came about as a way to simplify gut flora for people with IBD, GERD, etc..., but turned out to be a fast fat burner.
The simple starch in potatoes is converted to glucose quickly in the small intestine and transited through the bowels quickly. Eating protein causes the secretion of CCK which slows intestinal contractions, this allows the slowly digested protein to stay in the small intestine longer giving more time for amino acid absorption.
While an all-potato diet would be horrible for someone trying to build muscle, even in the short term, someone trying to lose fat as their main concern will see fast and lasting fat-loss from it.
Most find potatoes extremely satiating and it's hard to overeat on them. I, and others, have found it easy to eat at a 50% calorie deficit for 2 weeks, and not lose the desire to keep eating potatoes...try that with skinless chicken breasts or bananas as some have mentioned!
There are certainly other foods with this same effect, potatoes are easy to prepare a lot of ways and are cheap and accessible. A fat-fast has the same effect, but it's easy to overeat on and you can lose the taste for it quickly--but it is effective for much the same reasons.
Another thing I like about an all-potato, short-term diet, is the fact there is no fructose or sucrose involved. The liver is soley engaged in glycogen storage and release and not digesting protein and fructose. The intestine is cleared quickly and digestive bacteria are signalling at optimum level.
As to glycogen replenishment/water weight gain, nobody who's done this has experienced a huge jump in weight like one sees when doing a typical carb refeed. Most see weight loss from day 1.
This trick works, on seemingly 90% of those that try, for a weight loss of .5 to 1lbs a day or 5lbs in a week--10lbs in 14 days. I have never seen a targeted fat-shredding diet work so effectively for the dreaded 'last 10' as this.
If your goal is fat loss, take a break from lifting and try it out.
Made many of the same observations myself in the original thread....all ignored (hey I post a lot for shits and giggles so could be diluted)....after that I decided to stop raining on the potato parade. Still not buying it though.

From what I've read, if you continue to lift, protein won't convert into glucose until you've reached roughly 2g/lb of lean body mass. A 170 lb man at 15% body fat should be able to consume roughly 289g of protein on a PSMF before it gets converted into glucose. Lyle McDonald seems to agree with that in Rapid Fat Loss, where he encourages the diet of a PSMF to involve 2g/lb lean body mass of protein with virtually no fat or carbs, with only "calorie free vegetables" allowed as bulk (lettuce, cucumber, celery, etc).

Thing is, my measurements (waist, thigh, hips) are smaller than say, the mid-week measure. (it also fluctuates by about an inch between the post menstrual vs post ovulation phases -- bigger in the second phase).
We are doing a 16/8 IF protocol daily, and on weekends, we noted that it shifts from 16/8 to 18/6 or ever 20/4. On Friday, we eat potatoes; on Saturday we have bacon or venison sausages (i usually have the latter) with our normal breakfast (so it's a "bigger breakfast"); and then on sunday the same.
So, it's a carb day on Friday, then protein/fat on Sat/Sun, and then by monday, everything is back to the normal, rather spartan diet (veggies and meats/eggs with 1 piece of fruit; leaner meats, but other fats in olive oil, butter, and avocado).
We are also relatively lean overall. Before my binge (stress -- just eating more primal foods than my normal caloric intake), i was about 18/19%; we estimate that DH is around 9/10% or so (still. he didn't have a food binge! lol).
We started IF about two weeks ago now. I was already naturally doing it, really -- eating after 10 am and before 7 (longer window, but longer than normal fast for those who "eat breakfast first thing" or within the first hour of waking up -- which I have never been able to do without getting sick) -- but we pushed it to 11-7 to meet our schedule a bit better, and we'll likely shift it to 10-6 in the next few weeks (schedule changes).
The discomforts were two-fold: 1. a bit of hunger around 10:30ish with some crankiness around that; and 2. having to eat a lot more at the meals (or you end up grazing the whole 6 hours as well, which I found equally uncomfortable).
But, the benefits were nearly immediate. I'd been about 10-14 days on my normal caloric intakes, and continued that but within the IF window. Within the week, I'd lost most of the 1-1.5 inches that I'd wanted on the waist, hip, arms, and thighs, with an obvious change in leanness.
For the first time, not only can I see the line going "up-down" on the abs, but I also was able to see the left-right "hashing" on those abs at the end of the week.
It's the end of the second week, and the discomforts of big meals are still there (with the same caloric intakes as normal for me), but I'm also heading into the latter part of my cycle, so I don't expect to "loose" anything as i tend to hold a little more water during this phase. It's not much, though -- at most i gain about .5-1 inch on the waist/hips, and the rest stays the same.
though this cycle, i'm experimenting with keeping caloric intake the same rather than going up the 100-200 calories a day. So, i've been carefully watching my intake. I just wnat to see how it affects things.
Since going primal, unless i'm well off primal (grains across a week or more post ovulation), I don't have any PMS symptoms. If I am well on primal -- whether it's the pre-ovulation caloric amount or post-ovulation caloric amount -- I don't have any PMS symptoms except that I jump up to 26.5-27 inches on the waist. :P But it's not a "bloating water weight" feel.
I mostly have several goals: 1. staying healthy; 2. reaching fitness goals; and 3. making my life easier as much as possible. We discovered that IF has liberated a lot of time for DH and myself, which is great, and it isn't inhibiting 1 and 2 -- and might be helping -- so. . .yeah.
DH carb refeeds (or has a sweet potato) after his two heavy lifting workouts, so he carb refeeds 3x week (those two days plus Friday). He exercises fasted for his sprint day and one LHT. Just based on timing.
I do yoga fasted every day.
I would like to emphasize this:
"If you are hyperinsulinemic, do not do this. You must have a metabolism that is fundamentally healthy. If you are well on your way to metabolic syndrome, the all potato diet is a sure means to make a bad situation worse."
I am hyperinsulinemic, and a 'potato diet' (while appealing) would be a disaster for someone like me.
If I find myself up a few pounds, I find that the PSMF works best for me to shed those pounds quickly. I love my protein.
And all that nonsense about protein converting to glucose is misguided. In the absence of carbs, the body NEEDS that glucose, so the conversion is totally normal and not a problem--the glucose is burned off as energy, NOT stored as fat--unless the person is eating at a level of caloric excess. At if the person is eating too much, then ANY excess gets stored as body fat.
This is the "safest" way to crash diet and spare muscle mass.

I agree if you are in the middle of a muscle building phase and are concerned with hanging onto muscle you've spent months gaining, I think where an 'all-potato' crash diet makes money is for people who are trying very hard to manipulate their diet but still can't lose.
