Safe starches - not for most of us
Thursday, November 08, 2012
That is my conclusion after doing some additional research on Ron Rosedale's blog.
The reason is this:
While I believe that so-called "safe starches" are not as toxic as grains and beans and sugar, they will still raise insulin-levels and raised insulin levels always lead to fat storage and inhibit fat burning. Anyone who is overweight or obese or has a tendency to become overweight has probably been exposed to enough fructose and glucose from their diet (even if they eat low-carb now) that they are to some degree insulin-resistant and leptin-resistant. I had my personal example of this when I found out yesterday that my daughter's H A1c blood test came back at 5.7, right on the border to pre-diabetes. She has been eating no grains or beans and far less sugar than most kids her ago for the last 8 months and her weight is normal, her body fat percentage lower than average. But the occasional chocolate bar or larger serving of fruit or dairy must have been more than what her body needs.
Rosdale argues, convincingly, that there is a direct correlation between long life expectancy and low carbohydrate consumption.
The other disadvantage of consuming more than about 50-60 grams of carbs/day is that you lose the advantage of not feeling hungry or having any cravings for food, something that really helps with weight loss and weight maintenance.
So for anyone planning to experiment with adding safe starches to their plan I would suggest to have an H A1c test done to make sure that you are not in or very near the pre-diabetic or diabetic range.
If you are considering adding safe starches because you feel hungry this could be because your carb levels had not been low enough (under 50 grams/day or even lower for some) or your protein levels were too high and/or fat levels too low. It is also possible that someone is not feeling great on ultra low-carb because they are not fully keto-adapted, a process that can take between 2- 6 weeks, depending on the person.
I learned the hard way that every time I am out of ketosis (as I am at the moment) that even once I am back in ketosis it takes several weeks until I get all the benefits of increased energy. I'll really try to stick with it from now on, even if I get sick.
There are individual differences of course but I think they may not be as big as I used to think.
