I'd like to know more about this as well. My wife is diabetic and I'm pre-diabetic, therefore we've been eating low carb with occasional small portions of potatoes, pasta, etc.
I did read that potatoes may not remain "resistant starch" when reheated, and Inda here brings up heating methods and max reheating temps. So, more research may be needed. It doesn't seem like a priority in the food science field though...I mean, how could they sell you drugs if simply dong this could reduce blood sugar!?
Doing this doesn't hurt anything though, so might as well make it a habit. I'm trying to do it, using up all the carby stuff I have on hand...pasta, rice, etc..
If you have blood sugar monitors, you could always try an experiment like they story I told above. See what actually happens in your body.
There IS another alternative, at least for pasta. There are some really good LC pastas that really are very close to the real thing. Until I discovered them, I had gone to making my own LC pasta which was not bad, better than that nasty konjac
but not as good as these kinds
Problem is they can run $10-$20 a pound. You can buy a lot of protein for that!
There's an online shop called
Netrition I used to buy from. A lot of LC stuff to be had, some good some not so good but all of it expensive! I stopped buying when we went off LC...well, I have now put back on 10lbs in a year (Granted, its been a very tough year overall) after maintaining my weight well after LC for a few years; suddenly, last year, the great "swell up" happened so now we are making some different decisions trying to drop that weight again. May not be keto, but trying to make better food choices in the long run while eating through some of the stuff we already have to be rid of it.
There are decent LC breads out there too. Schmidt 4-6-7 not only makes the sliced bread but now, bagels, English muffins, hot dog buns, sandwich/hamburger buns and hoagie rolls, Problem is there is only one grocery store here that carries all of them (Giant Food) and those shelves are hit and miss, gotta buy it when you see it!
I have taken a new stance a few years ago....there is no food you can cook at home that comes anywhere near as harmful to you as what you get in a restaurant. I think someone should sue the fast food industry...because there is no food in that garbage they sell. Every restaurant I have been roped into going to the last couple of years is all cooked by chef Mike-row-wave. processed food, reheated and served as fresh. Unless you go to a place where you see the food cooked-I'll bet it came out of a box.
My next beef is with the school system. What the hell happened to feeding your kid breakfast before they go to school? No offence to Mrs Obama, but really. A teenager cannot function on an 80 calorie yogurt cup and an apple.
And that was the biggest thing the release of this inverted pyramid came with, telling us to eat whole foods, not processed foods. Some of the restaurant food out there is fine (I dont consider fast food a "restaurant"), but many have started to use Sysco Systems and U.S. Foods, etc. as a supplier. It's why so many places that used to not be bad are now all tasting the same...mediocre. It's all packaged, pre-cooked, portioned, etc..
Part of how we got fat again was entertaining my dad after mom died last May. He loves to eat out, and I was kind of in a "screw it" mode when she died and didn't feel like cooking anymore. So we started eating out regularly with my dad to keep him busy on nights he didn't have other activities. He went back down to snowbird in FLA (lives next door in summer here) and we actually felt relief that we didn't have to go out to eat! I mean, after a while there are only so many restaurants to go here and most of them are not stellar. We had grown tired of them, and now my interest in cooking is starting to come back.
School lunches...man...when I was a kid I was envious of those "poor kids whose mom apparently cant feed them". My mom didn't cook stuff like eggs and breakfast meats for me...cant remember exactly what she fed me, like with everything else, I loved my mom (once I turned 18 and left home!) but she wasn't much of a cook, so I literally dont have those "mom used to make the best" memories. I probably got cereal, maybe oatmeal. But getting off that school bus and walking in to the school to smell all that great food, cinnamon toast, etc....man I wanted to be "poor" so bad so I could get that stuff!
