  • My white potato n=1

    I have been pretty liberal with my consumption of sweet potatoes since going primal. I have kids, they love them and they need the carbs. I prepare them several times a week for dinner and eat them probably 5/7 days a week. They have not impacted my ability to drop weight or ever made me crash. So last week were visiting my husband's aunt and she made a brisket cooked with white potatoes. Man they were delish all drenched in beef drippings. It got me wondering if we could incorporate them back into our diet occasionally. This week I decided to try allowing some form of white potato into my mouth for a few days, but still kept my carbs at around 100g a day,which is where I naturally fall when I eat Primal on a typical day. SO I had potato chips fried in Avocado oil one day (best potato chips ever!), regular homemade french fries the next, and last night due this cruddy cold I just wanted something bland so I had a chicken leg and mashed potatoes. 3 days. . . 3lb weight gain! This is the time of the month I typically drop a pound or 2. So goodbye white potatoes, you are so not worth it!

    Sweet potatoes really are magical!

    It's not possible to gain three pounds of fat from less than 300 grams of potatoes in 3 days. Water weight.

    Sweet potatoes are magical, though, I agree.

      It's very unlikely the potatoes made you gain three pounds of fat. you would have to have eaten 10,500 calories over your intake for that to have happened. Weighing yourself is a terrible way to gauge if you gained fat. Your weight changes everyday from a huge amount of factors, eg. Water intake, how heavy the food you have eaten is, glycogen stores, Water retention, What food is still digesting, if you have gone to the toilet etc. I eat white potatoes everyday and i stay lean. It's more about your carb intake rather than the type of carb. If you eat the carbs with protein and fats, the digestion is slowed immensely, regardless of the type of carb.

        I'd be willing to bet you experienced an inflammatory response to the cooking oil. Happens to me every time. I used to blame the eggrolls, french fries, fish, etc... but turned out to be the frying that caused rapid weight gain in me. A good N=1 for you now would be after all your recent weight fluctuations have settled down, try eating sweet potatoes cooked the way the white potatoes were, in the same oils. Do you know what oil was used for the 'regular homemade' fries? Maybe they were using some really rancid soybean oil or other wonderful oxidized marvel of technology.

        Giving up all fried food, even fried in butter/bacon fat, was the best move I made. I use these fats to cook with, but not to the point things are fried hard and brown--just soft and sauteed.

          I agree, I doubt the 3 pounds was fat gain, although you may have an inflammatory response either to the white potato (do you have issues with other nightshades?) or the oils used in cooking. If your overall calorie count and macros stayed the same, I can't imagine how you'd put on that much weight that fast. Did you track for other variables?

          I've eaten white potatoes almost daily over the last few months, sometimes twice a day and in much larger volumes than I'd guess you're eating, and I've continued to get leaner. Also an n=1, but white potatoes are not necessarily only for the young, lean dudes (I'm a woman in my mid 30s). However, for my 20-something brother with a nightshade sensitivity, that's a whole other story.

            Potatoes are more nutrient dense than sweets, and the two are more or less equal as far as fiber, resistant starch, and protein content go. It doesn't stand to reason that they'd be inherently more fattening.

            And I don't see why people stress out over a weight fluctuation of 5 lbs. My weight will swing almost 15 lbs in either direction when I alternate low & high carb.

              If they werent a bloody nightshade i'd eat them liberally! Instead Parsnip is my substitute.

                I really dislike posts like this. They always end the same way - a person consumes some kind of carbohydrate, their weight goes up due to water retention and glycogen repletion and they conclude that said food makes them fat and will therefore be off limits.

                White potatoes are very high GI. If you are following some kind of cyclical ketogenic diet with a massive refeed over the weekend that culminates in very high carbohydrate intake with little to no fat, white potatoes are going to be awesome - better than sweet potatoes. You'll replenish glycogen faster and actually bloat less. However, if you're going to combine high GI carbohydrates with fat and salt (like in a beef roast), you're going to bloat a lot. White potatoes and salty, fatty meat is really going to pack on the water weight.

                It annoys me that sweet potatoes are so beloved by The Primal Blueprint but white potatoes are often shunned for some reason. Mark Sisson is always recommending sweet potatoes for a great carb source but I've never heard him recommend white potatoes. Why? Here is how a paltry 300 calories of raw white potato compares to 300 calories of raw sweet potato:

                Many of you will be shocked that white potatoes are just as nutritious as sweet potatoes. In fact, the only outlier - Vitamin A on a sweet potato - is going to fade away if you're not eating the orange, beta carotene-rich jewel or garnet sweet potatoes. White varieties will lose this outlier. Also, factor in you can eat 86g more white potato for the same caloric impact. Sweet potatoes are more calorically dense than white potatoes and are not more nutritious, so realistically, white potatoes are more nutritious per gram (and equal per calorie) than sweet potatoes.

                Now, that's not to say I don't like sweet potatoes. I love sweet potatoes. This is what I bought today:

                That's 20 lbs of sweet potatoes, and they're all sitting in my closet. I don't have any white potatoes right now. I typically eat sweet potatoes because I like them more than white potatoes. But they are not better nutritionally and they won't make you fatter. A white potato is just as healthy as a sweet potato, so pick the one you like best.

                  I see you're fond of the typical Japanese cultivar By far my favorite too next to perhaps some of the purple varieties.

                    I am sure it is just water weight and will come off after I workout tomorrow. I am feeling significant bloat which I don't normally experience. the fries were just tossed in olive oil and baked, chips in avocado oil which I use all the time and have no issues with. Sorry to ruffle so many feathers, I was just sharing my surprising reaction. Mybweight does not typically fluctuate up like that unless I am approaching my period, which I am not. I am not carb phobic at all and have mostly eschewed white potatoes because I didn't miss them until this week. Since the rest of my diet was the same typical stuff I eat, I now know that white potatoes and I need to be an occasional thing only. Isn't that the point of an n=1? Sorry I touched a nerve . . .

                      Carb phobic or not, I am finding that these type of experiences are handy pieces of information to have. I havent had potatoes for awhile either, since I am in weight loss mode and watching carbs & calories, but when I want some it would be nice to know it's affect on me, even if only temporary and where it shows up. If it is like a pudgy belly or pudgy face, I wouldn't want to have them before a special event, especially if I am trying to fit into a certain dress or something.

                      But that is not to say I wouldnt ever have them, I just have to keep in mind what might happen. Perhaps only one day of it might not have been so bad? That might be another experiment.

                        It might be because white potatoes are nightshades which can be inflammatory for some people. Since the primal blueprint is meant to be an anti-inflammatory Mark may not recommend them to avoid the problem that they may cause in some people.

                          I think you all who mentioned nightshades might be on to something. I have noticed I naturally started avoiding tomatoes for some reason and last weekend I had some and ended up with a horrible heartburn. I wonder if I have an issue with them? Maybe my next n=1. Hmmm....

                            i truly dislike sweet potatoes. yukyukyuk. a starchy food that's sweet? yuk.

                            i had 1/4 of a local white potato yesterday and did not die.

                            am not bloated and scale did not go up.
                            As I ate the oysters with their strong taste of the sea and their faint metallic taste that the cold white wine washed away, leaving only the sea taste and the succulent texture, and as I drank their cold liquid from each shell and washed it down with the crisp taste of the wine, I lost the empty feeling and began to be happy and to make plans.

                              It's good you posted this. It happened to you and you are relaying it to us--that's an N=1.

                              I remember when I was about 3 months into PB. I had a setback one weekend and ate fried eggrolls, piles of rice, cake, M&Ms, Doritoes, etc... I gained 12lbs from those 2 or 3 days of unrestricted eating. No way it was the calories, just the inflammatory response to something that was eaten. It took me nearly a month to get back to where I was before this mega-cheat.

                              I think the more body fat you carry, the more inflammation can occur. At that point, I was at about 35%BF, now I'm at about 15% and my weight rarely fluctuates more than 2-3lbs no matter how much or little I eat. I have been eating lots of white potatoes recently because I grow my own and they are being harvested. Hasn't caused any weight gain.

                              N=1 is a very important tool for this community. It's just when someone tries to apply it to the entire population that it is wrong.
