Potato hack question about Resistant Starch

[Dottie]

This may have been asked before, if so -sorry.
I have read a lot about the fact that cooking, then cooling potatoes converts their starch into a RS (Resistant Starch) that lowers the glycemic impact.
My question is: does re-heating the potato after cooling it break the RS down (or make it a regular starch again)?

[piratejenny]

I've been wondering about this for ages!
I found this:
"When foods like pasta, potatoes, and rice are cooked and chilled, tight crystals of resistant starch form. Don't reheat them; you'll break up the crystals."

Resistant Starch - Foods with Resistant Starch - RealAge

[Dottie]

Well thanks (I guess!) lol j/k - yes it's been a question I've had since I started reading about this.
So if you eat them cold, they're lower glycemic.

[piratejenny]

Yeah...I was hoping it was okay to cook a bunch, cool them, then make hash browns or something. Dagnabbit!!!!

[Dottie]

Interesting, too, the articles about adding 2 teaspoons of vinegar to a meal will reduce the glycemic index by up to 20%. So maybe if you want hot potatoes, that would help!

[ouizoid]

but see, here is the thing I am not sure about--I think we WANT the big insulin surge in the absence of fat or protein --and that mobilizes fatty acids to neutralize it. That is the one thing I am not sure of with the whole resistant starch deal.

[LoCarbGal]

That's my understanding too, Ouiz. Seems crazy for us long time LCers. It's knee jerk to want lower glycemic foods, but in this case, I do think we want all the blood sugar and insulin surge for the subsequent fat burning. I wish there was more science on this!

[piratejenny]

Ouiz, you're right about the insulin surge theory.
But only a small percentage of the starch becomes resistant.
Maybe that, and/or the vinegar, just helps with part of the starch not being digested (or being digeste more slowly), and dampening the reactive hypoglycemia/rebound hunger.

So you still get (most of) the insulin surge, but you don't get hungry again as quickly?

so i'll ask my question here...not sure if it's been seen yet in the BIG thread...could this be done with oats? i was reading about them and they seem to be a RS like potatoes.

what is your opinion one this?

[adillenal]

I had not thought of it BUT on my potato days I eat oat bran for breakfast and then potatoes the rest of the day. Maybe I am on to something accidently.

[dazygyrl]

i have actually been reading about RS foods...why couldn't you do this with any combo of RS foods...oats, potatoes, navy beans, brown rice?? i read navy beans are extremely high in RS. i could totally do this mixing up all sorts of RS foods. my only prob is i don't have potato only to compare to.

[piratejenny]

I suppose you could try it with any non-fat food that has resistant starch.
But potatoes just blow away other foods on the satiety scale.
Also, what satiating for one person makes another eat all day long--
we've had these discussions about oatmeal for breakfast, for example.
Some people find it keeps them full for hours and they eat less overall,
others find they get hungry again quickly.

While I was reading about RS last night, I did notice some comments that resistant starch is present in whole grains. I guess this might mean that once you grind them up, the starch is quicker to digest (I have heard that instant oats are higher glycemic than thick rolled oats). So I would try whole oat groats--perhaps that's what you meant, since you said oats and not oatmeal.

[dazygyrl]

yes, i meant old fashioned oats or steel cut even. oooo! i do have groats at home. what's the verdict on canned potatoes?

maybe i shall try this.

Ray Cronise has an excellent website that has lots of info about the science behind this hack. Unfortunately, I am not able to post right now, but he has helped several people who were diabetic and hypo do this hack and lose well. You have to register to read his site, but it is mind boggling to read the testimony of the ones who this worked so well for.

His site is hypothermics.

[dazygyrl]

was it all forms of RS, sunday?

[sunday]

Mostly, potato, but I believe that some of the guys did rice and squash.

[Dottie]

Interesting.
I know that the starch/carb blocker pills are made from some white bean. Could be something similar going on here.

[Yennie]

I think the problem with things other than potatoes, well, beans anyway is they are so high in protein that it deminishes the affects of the glycemic surge.
I've been cooking and reheating my potatoes and losing well. And also feel full for hours. I try to separate my potatoes 4 hours on either side of anything else.
Sometimes I do potato 1/2 days, then eat something else. I did that on Saturday, a DD. Potatoes all day, then nothing for 4 hours, left over chinese and even a sliver of my Grandma's apple pie (Best. Pie. Ever!) Pigged out yesterday on my UD, didn't count but I'm sure I went way over (among other things more of said pie and some ice cream) and I'm down 1.8# this morning. AFTER AN UD!!
I give credit fully to the potatoes. I try to incorporate a mini-hack into each day now.
LOVE LOVE LOVE this!!!!!

[dazygyrl]

do you feel it is necessary to do the hack for several days in a row initially to get all the benefits? i'm having trouble finding more than 2 days in a row to do this!! i tend to go out for lunch either with my sister or my friend every week...sometimes both in one week.

in other words, is it still beneficial to simply start doing this on DDs only?

[dazygyrl]

regarding protein content...

in my online calorie tracker, it tells me there are 8 g of protein in an 8oz baked russet potato and 7g of protein in 1/2c of mrs. grimes navy beans. soooo, if one were to mix and match, it doesn't seem that there would be more protein if doing this with a meal of potato and later a meal of some beans...is there?

[sunday]

Dazy, I do it for 2 days myself. Four days is what I have planned for this round, but you should see results even if it is on Day 3/4 after you have terminated. I have watched many who do not see a loss until a few days later. Which is rather interesting.

[adillenal]

I am actually only doing the potato day on my DD's. I am only trying to maintain and it is working well for that but I am eating all the cold boiled potatoes I want on my DD's and I am not gaining and that was the purpose for me to try it.

[dazygyrl]

regarding protein....when i look the nutritional facts of an 8oz baked russet and 1/2 cup of canned navy beans, i'm getting 8g protein for the potato and 7g for the beans?

[Yennie]

Seems like it should work then although I've read many places saying its the unique blend of carbs, protein, etc that make the potato ideal.
I've yet to do this for more than a day & a half at a time. I tried a hack & bailed by the evening of day 2. Solike, Adi, I'm doing potato DDs, and I'm losing. My last DD was potatoes all day until the evening when I ate chinese food. Still down on the scale. So, like I said before, I'm trying to incorporate the theory into each day, even UDs. One hack meal

[dazygyrl]

i think i'm go ahead and try this the rest of today (evening meal of oatmeal or potato), tomorrow...wednesday is lunch with my friend, but can do the hack for my evening meal, then i can do it thurs and friday...i may have lunch with my mom and sister on thur or friday so will adjust for that.

Have fun! Interested to see how this goes for you. Love the pic of your kiddos.
