PK, I adore you and your blog. Thank you for your insights and remaining as calm as humanly possible while getting flamed. I haven't been around the boards much lately due to my Dad being in the hospital and then convalescing and I was dismayed to return to find the great potato madness standing with nary a questioning voice.
In my opinion, this is what gives this forum its interest, seriously.
Of course people here like ChocoTaco, PaleoBird, or pklopp may have very lively ways to express their beliefs, but they're not uninteresting at all and they all give something to the knowledge of posters. And it's often backed by very documented pieces of stuff...etc
I, too, had a bit of difficulties to appreciate Choco's posts for what they're worth at the beginning, when I first arrived on the forum, however, you should place all of that in its actual context. These people are like you, humble posters and they don't think they have the absolute truth. However they're convinced by things and I think it's the most important motor of life. (EDIT: When it's not total bullcrap and dangerous for your health i.e.: silly veganism.)

About Choco. We have crossed swords a few times but there have been several times when we have been on the same side of things. Even when I disagree with him I respect that he has done his homework. PK is someone else whom I respect greatly. And don't get your panties in wad about the great potato madness comment. It was meant as light hearted rhetoric.
I started the "MOAR taters" thread in homage to your "MOAR fat" thread. I came across this hack for weightloss last summer and tried it on myself and close friends to great success before posting it on MDA.
I'm not the mastermind of the 'Potato Diet' but I have invited him to come and talk about it. You will be surprised when you learn who it is. If I can talk him into posting here, I'll start a new thread so you guys can get all your questions answered by a real expert in nutrition.
I implore you to read through the tater thread and look at the results. This is nothing more than a well-designed, short-term fat-busting hack. It's not a life-long diet plan. It is repeatable and predictable.
I love it because it's as ancestral as anything we do. Most, if not all, cultures since the beginning had access to starchy tubers. Undoubtedly there were certain times when they had to rely on these tubers as a sole source of food. I really like that this is coming out now, in the Fall, because this is the perfect time to add a short-term starch feast into your life.
Otzi, while I'm currently not even considering trying your potato experiment, I want to thank you for taking the time to post about it here. This is what this place should be about.
PKLOPP, in the original thread I mentioned that in my teens and 20s I used to do a one week weight loss hack that typically resulted in a loss of 7-10 pounds. The "diet" was all lean protein. No carbs. You got minimal fat along with the protein, so that may have spared protein being broken down for energy needs. In your opinion, does this protein diet hack seem to work on a similar principle as the potato hack? I plan to end the potato project with two of three days of the lean protein regimen as a transition to my normal Primal diet.
As an example, consider the 700 daily calorie potato diet I referred to earlier, which would require you to eat 720g of baked Russet potatoes and get you 18g of protein in the process. Were you to eat 700 calories worth of a sirloin steak, that would work out to be 290g and that gets you nearly 80g of protein for your trouble!
So you would need to eat nearly 2.5x the weight of baked potatoes to get the same same amount of calories from beef. But that is not nearly the entire story. The next question is, what volume of potatoes would you need? Well, the density of potatoes is roughly 0.769 grams per cubic centimeter, and for beef, about 1.042 grams per cubic centimeter. That is, beef is about 1.4x more dense than potatoes, which means that you would need to eat 2.5 x 1.4 or 3.5 times as much volume in potatoes as you would in beef to get the equivalent calories.
The volume of ingested food is important, because insulin production is governed to some extent by stretch receptors in the upper portion of the small intestine, and as the intestine stretches more, more insulin production results, and this is important because the beta cells of the pancreas don't just secrete insulin, they also secrete another hormone in tandem with insulin : amylin.
Amylin is rather interesting because it results in the slowing down of gastric emptying, inhibition of digestive secretion [gastric acid, pancreatic enzymes, and bile ejection], and a resulting reduction in food intake (i.e. it suppresses appetite! )
So, all else being equal, of two isocaloric meals, the one resulting in the higher insulin release would result in the higher satiety, and slower gastric emptying.
The more I think about, the more likely it seems that amylin is probably a good candidate for being the mechanism by which potato diets are so satiating. Interestingly, amylin secretion is also stimulated by fatty acids.
Fundamentally, I think if the satiety aspect is equivalent, then a protein feast is far superior to a potato feast. It is not apparent to me, however, that equivalent satiety would result from an isocaloric lean protein diet relative to a potato only diet. You are probably better off, from a satiety standpoint, to select fattier cuts of meat.
As I recall, the idea of the lean protein was that it was supposed to ramp up your metabolism and you'd burn fat. I don't think it was intended to be calorie restriction, although I'm sure I tried to take it easy on the portions. Oddly enough I think I used to be hungry moreso than on this crazy potato diet, but it may be due to the fact that I am currently very adept at burning fat off my body as fuel.
So I was hungry first thing, so I at this morning. 3.5 oz steak. 3 eggs, little CO. It said 2 meals, but I knew I would have 3 probably. Well by noon, I was already at 1000 calories. And I was hungry again at supper time. Now my calories are coming in on the high side of what I am use to, still under BMR but barely. And I am probably the 700 tator calories you are referring to, as there are some days that 700 calories of tators is all it takes. Some days 1000 some days 1200. But point is, I get full fast for longer, on tators. Or it would seem so based on just one day today so that probably isnt fair either, especially since i just had 3 low cal days. But no doubt, it would probably take longer to get sick of steak and eggs. And again it was eggs also, not just all steak so maybe not apples to apples.
And I know that you are using 700 calories was just for example purposes, and we are not tripping on 700 calories now and then because when I IF, it is far fewer calories than that for a few days in a row.
Anyways, I did like the steak and eggs. Not much thought goes into that either. I could do that for quite some time if I can see results. I just know the tator is about .5-1lb loss per day. (One day I actually had 2lbs) So it is nice to have these little tricks up my sleeve based on what I need to accomplish.
