  • I'm not sure if this will be helpful to anyone, but here it goes. The potato-diet idea seems to come from a few independent lines of thought. One is the experiment that Chris Voigt did. Another is the long, disorganized, tangential discussion on Ray Cronise's blog. Stephan Guyent has also added some insight.

    In any case, after I saw the threads here about it, I tried the potato diet myself for one week and lost about 8-9 pounds while feeling very full the whole time. I was trying to eat more than my appetite dictated, but potatoes are extremely filling. Anyway, I later went back to the long and disorganized comments in Ray Cronise's blog, and organized Cronise's statements into a little FAQ. The following is based only on Cronise's statements; it doesn't incorporate any of the modifications or enhancements from the threads here at marksdailyapple, or from Voigt or Guyenet, or from any other source.

    Potato-Diet FAQ

    What's the basic protocol?

    You will lose weight fast by eliminating meat, butter, oils and any sugar from your diet, and sticking to only brown rice and/or potatoes for 14 days. Either white potatoes or sweet potatoes are fine.

    You can eat as much as you want, but don't eat just because it's "time." Eat only when you're hungry, and stop eating when you're no longer hungry. Skipping meals is okay.

    Drink lots of water. No liquid calories of any kind.

    Can I add flavorings?

    Yes, but any flavorings should be low in calories and devoid of fat. Salt, pepper, herbs, and spices are fine. (Rosemary and chives go well with potatoes.) Soy sauce, vinegar, and hot sauce are fine.

    Doesn't this work merely by creating a calorie deficit?

    All diets work by creating a calorie deficit. This one is no different other than complete satiation and paradoxical control of blood sugar with a high-glycemic food.

    Let's say your resting metabolism rate is 2200 calories. A 153-gram potato has 110 calories. That means you can eat 20 potatoes a day to break even. That's a lot of freaking potatoes. One cup of cooked rice is 160 calories. That's 13 cups of rice.

    Starches are enormously satiating and way more satiating than simple sugars or fats. You might eat 20 potatoes or 13 cups of rice for a day, maybe two or three days, but I'm betting you won't keep it up.

    If you eat to satiety, you may end up eating only 3-4 potatoes a day or about the same amount of rice. The result is that you'll feel satiated while running a large calorie deficit.

    What's so special about potatoes?

    Potatoes are starches with complete protein, vitamin C, and a host of other micronutrients. You're basically flooding the body with glucose, while having just enough protein to remain nitrogen-positive. You're also getting a decent amount of vitamins and minerals while avoiding simple sugars.

    A large serving of starch when you are glycogen replete often results in diet-induced thermogenesis. While a reduced-calorie diet will often suppress metabolism (inducing "starvation mode"), the excess of starch on this diet actually ramps up metabolism to burn more calories.

    Flooding the body with glucose, in the absence of simple sugars or fat, is a simple trick to rack up a huge calorie deficit while remaining very satiated.

    Won't a potato-only diet result in nutrient deficiencies? What about fat-soluble vitamins?

    The idea that any nutrient is just days or hours away from being deficient is a myth. Besides, what makes you think metabolizing the fat on your body is any worse than digesting the fat in a salmon or pig?

    Can I add non-starchy vegetables, like spinach?

    Greens and other non-starchy vegetables are fine, but for purposes of the experiment, why not just eat potatoes? It's simpler and gives you less to worry about.

    How about other forms of starch, like beans, peas, or lentils?

    Any starch will work, but go for something that has a good amino acid profile. That's why potatoes are ideal.

    Why can't I add fat? Potatoes taste a lot better with butter.

    Adding fat would defeat the whole purpose of doing this. The point is not to give into cravings — especially for fat. Also, since you are flooding your body with glucose, any fat you consume will not be burned. It will go directly to adipose tissue.

    Can this work as a long-term diet strategy?

    It's not recommended. Potatoes are somewhat nutrient-dense, but they do not contain every nutrient your body needs. After 14 days, you should transition to a more complete diet.

      That was awesome! Took some real digging to get all that from those comments on Ray's blog! I wish he would have stuck with the potato diet a little longer, he seems completely divorced from it now.

      • thanks again Otzi. Well it's true I do not eat fish cuz I hate it. I'll eat some tuna but that's it, would that be ok? Ate another half a P at 6:45 and added some fresh salsa and couldn't finish it!! I am now totally stuffed feeling and fell much better!! BG only spiked to 122 at 30 mins post now at 1 hr 106! WOw this is so neat I wonder if I used up some insulin or some other hormone cocktail?? I feel totally "normal" now.
        I felt great on what i was eating. I did do raw milk for awhile in my shakes but then cut it out. I think even milk sugar is too much for me so off the dairy again to see what happens. I don't do any nuts any more a la Ray Peat. My favorite meal past few weeks has been a smallish potato cut up with some poultry and either broccoli or greens, butter and some sour cream, maybe a little cheese, bacon. Or last week it was all turkey/potato/guacamole/salsa all mixed together. YUM YUM, felt great and loved every bite. as soon as I added the taters back in my temp went up, cold hands went away, tons more energy, total difference!! Major improvement. So I know I need some starch but trying to figure out if I can handle any sugar even from fruit or dairy and what level of fat. I don't do chocolate because I can't do ANY caffeine. I do take bunch of supps: mag, Vit D, liposomal Glutathionine, B's etc. Am headed to bed now so will see what the am numbers are! Very interesting that i feel so much better now and after each potato my BG spiked lower and lower.

          I know a lot of people rarely eat fish and do fine, but my cholesterol numbers took a huge turn for the better when I started eating lots of fish. I try to get a serving every day. Tuna is fine, sushi is great. Shrimp, oysters, salmon, and sardines are all pretty tasty and easy.

          I also try to eat liver, usually chicken, once a week, and make a pot of bone broth every week or two and use when cooking or make soup with. A lot of nutrients are better gotten from foods than supps, but you look like you are going in a good direction with everything.

          • scale down from 162.2 to 159.8 this am!! And FBG of 90 which is pretty good for me! Gonna give this another day. I feel great this am and only woke once at midnight (pattern last two nights) but fell right back asleep. Off to shred some golds for hash browns...

            Do you worry about the mercury in fish?? I'm having all my fillings removed now to try and detox my body as best I can. That's another reason I never pushed to make myself develop a taste for more fish. I do make my own bone broth and also keep a stock of the Real Broth you can buy now. So I have some almost everyday. I wonder if I ground some liver into beef if the taste would disappear?
            My cholesterol was perfectly fine although HDL was VERY low before I went Paleo, but now all numbers have jumped, so I'm just in "normal" range now. Don't think anything needs to go higher for sure. I also try to eat or take a ton of fiber if I don't eat enough veg.

              What sort of fiber do you "eat" or "take a ton of", if not food?

              • I have a great fiber supplement that is a mix of Psyllium, oat and pectin that provides 17 g fiber a serving. When I was doing VLC I used it to keep things regular, had good results with no bloating or gas. They market it as a weight loss supplement to make you full or something but I just kept it around for when I was trying high protein. Usually I eat 2 cups of spinach in my am shake, a big salad at least once a day, and usually a few more servings of veggies. So have not needed the fiber in quite awhile.

                • I've found eating both raw and cooked vegetables keeps me moving. I can't eat oats, and psyllium, er....

                    Looking good! I've never worried much about toxins in fish, but I do tend to eat sardines mostly since they are at the bottom of the food chain and less likely to get the mercury and stuff bigger fish like tuna and salmon can accumulate.

                    • Went on a "clean" potato day yesterday: 3.2 pounds (cooked weight) of Yukons, reds and russets yesterday, and cut out the sweet potatoes and chicken stock I'd used on the first two days. The last 0.8 pounds of reds was eaten at 5:00 PM, had the second enormous BM of the day at 9:00 PM. Also drank at least 4 liters of water, coffee and tea throughout the day.

                      Had no problems getting to sleep at my usual time last night, slept well and got a full 8 hours.

                      Weight this morning at 9:00 AM? 207 pounds after an epic bladder voiding (fairly clear too). That's six pounds up from my start weight of 201 on Tuesday morning. This is not particularly encouraging.

                      Worse, it looks like I swallowed a bocce ball and it's stuck in my solar plexus region, so it's clear things aren't moving along as well as they should, despite the extreme and voluminous regularity I've had since starting the potato hack. I'm guessing after a year and a half of no starch my gut flora just isn't up to the task of handling what I've been sending its way in the last few days, and there's a fair amount of water binding with all that new glycogen as well.

                      Haven't eaten yet today, but there's a half carton of eggs and freezer full of meat calling my name. Any thoughts?

                      EDIT: I should note I'm not sick of the thought of eating potatoes, the actual eating of them is going just fine, I'm sure I could eat a few right now and enjoy it. I'm just seeing results going the opposite direction than I'd hoped, which is why the meat and eggs are on my mind.

                      • Well, you know it's not 6 pounds of fat, can't be. Impossible. It's just water. I'd say stick with plain potatoes for 2-3 more days if you can handle it. Do you normally drink 4l of water? I rarely even drink 1l, even counting coffee, but drink when you're thirsty for sure.

                        Comment


                        • Yeah, 3-4 liters has been my daily fluid intake for years.

                          And yeah, I know it's mostly water weight, but that's running counter to anyone who's had success with the potato hack (I'd read every thread here on it, and every scrap out in the wild internet before starting this).

                          The abdominal bloat is also suggesting there is some sort of digestive issue over and above the water retention.

                            Are you using a ton of salt, by chance?

                            You are right, though, usually the potato diet gets rid of water weight--not causes it. I use quite a bit of salt on my potatoes, probably more in a day of potato eating than a day of regular food, but overall probably about 1tsp or less, just guessing.

                            • Did you all see we made the news! Well at least in this blog anyway: Whole Health Source: Glucagon, Dietary Protein, and Low-Carbohydrate Diets

                              Beyond the metabolic/hormonal effects of low-carbohydrate or high-protein diets, these diets may also be effective because of changes in the reward and palatability value of the diet (and food variety, a related factor). Getting rid of pastries, donuts, soda, fries, and pizza goes a long way, and taking one or more items off the table (e.g. bread) tends to reduce total food intake even if everything else remains the same. The potato-only diet is a good example of this (19, 20). Over on Mark Sisson's forum, a number of people have been repeating Chris Voigt's experiment of eating nothing but potatoes, with similar weight loss results (21). To be clear, I'm not recommending this approach, but it certainly illustrates the power of a monotonous diet. Interestingly, besides being extremely filling per calorie, potatoes are also one of the most insulin-stimulating foods, according to the paper cited above.

                              • I'm going to pop in here as a pretty irregular poster on MDA. I'm just wrapping up an awful bout of stomach flu and despite Mark's recommendations on what to eat with an upset stomach, I still can't bear the idea of eating much other than starch (aside from a little bone broth and full fat yogurt). The idea of just eating mashed potatoes for several days is really appealing on a gut level right now... both literally and figuratively. Aside from the weight loss implications (not my biggest worry at the moment), does anyone see any problem with giving this a try while in a somewhat depleted state after a week of gastroenteritis?
