It's going to be hard for people to out-eat their daily caloric requirement on potatoes if they are overweight, yet it's doable for someone with a lower caloric requirement.
"Adoption of a potato-based agriculture is credited with the virtual elimination of famine in Europe by the early nineteenth century. As a testament to the capacity of the potato to support people, between 1801 and 1851, the populations of England and Wales doubled to almost 18 million people, and the Irish population was able to double to eight million between 1780 and 1841 as a direct result of the widespread cultivation of the potato. Fortunately, the common potato is now being rediscovered as a nutritious crop, producing a delicious food, which will cheaply feed an increasingly hungry world. This enlightenment has the potential to save the human race from starvation, as it has done for so many communities in the past. The United Nations has declared 2008 the “International Year of the Potato,” and for good reason: to raise “global awareness of the potato's key role in agriculture, the economy and world food security.”
I looked at that 100 grams of glucose and the baseline for 4 groups within the hour graph, posted by pklopps. After scratching my head, I concluded that I am in the obese groups (definitely!), but not the diabetic groups. I looked again at where the blood sugars ended up in one hour. All I have to say is - what were those 100gm of glucose made of? I've been eating only taters today, and tracked my sugars sporadically, but faithfully for an hour after lunch. Starting at 5.3 (95.4 ), in 15-20 minutes from starting to eat my cold potato with salt and hot tea,, it went to 5.7 ( 102.6 ), then to 8.2 (147.6) in 15 minutes, then back to 6.3 ( 113.4 ) in the next 30 minutes. Basically, it shot way up and then receded in about an hour. I probably ate more than 100 gms of potatoes, as I can eat 2 at any time, and sometimes 3. These are mixed, but not small potatoes.
Why cold potatoes? Because I'm lazy, and roast a batch and refrigerate the extras. If I want/need to, I will reheat them. If I were to add vinegar with the salt, I'd likely get more down, because vinegar sharpens my appetite. So far today I've eaten the skin, but I've eaten them without as well. Could I eat like this for 2 weeks? Likely not, but for a weekend or non-busy few days, probably. Do I think I'll harm myself? Of course not. It's just one of those simple little n=1 experiments I try occasionally, just to see what happens.'
PS. I am not several orders of magnitude way above my baseline in an hour. But if that were pure sugar, I might have been! And starving all afternoon, to boot.

Fat 2 Fit - One Woman's Journey
You argument as presented above is:
- Humans are uniquely designed / evolved to eat tubers ( starch ).
- Tubers may very well have been the only food source available during times of scarcity.
- Therefore, when an organism encounters the perfect food for sustaining it during times of scarcity, rather than being weight stable, it starts to lose weight at an accelerated rate.
I used the phrase non-sequitur earlier, and just in case some people are unfamiliar with it, it literally means "it does not follow." And a perfect example of this is point 3 above. It directly contradicts points 1 and 2.
Here's how that would look if it did follow:
- Koala bears are uniquely evolved to eat Eucalyptus leaves.
- In the absence of Eucalyptus availability, Koalas rapidly lose weight and ultimately die.
- Therefore when the Koala encounters Eucalyptus, it is weight stable, and even exhibits growth periods.
F 5 ft 3. HW: 196 lbs. Primal SW (May 2011): 182 lbs (42% BF)... W June '12: 160 lbs (29% BF) (UK size 12, US size 8). GW: ~24% BF - have ditched the scales til I fit into a pair of UK size 10 bootcut jeans. Currently aligning towards 'The Perfect Health Diet' having swapped some fat for potatoes.
One does not eliminate famine by making formerly fat people skinny. In fact, famine is a great way to do that. Moreover, reproduction is predicated on nutrient surplus, so the doubling of a population over 60 years is a great indicator of surplus energy that can be dedicated towards sustaining a conceptus.
I have yet to see a nutrient surplus being advocated as a miraculous weight loss technique, but I guess that if you live long enough, you do get to see it all!
