Why you should eat non-starchy vegetables

There are 3 macronutrients: Carbohydrate, Protein and Fat.

All vegetables are carbohydrates and carbohydrates turn into glucose. Protein also turns into glucose, but through a much longer process. Fats turn into fatty acids.

Here are two really important facts:
  1. Glucose requires insulin to be stored as body fat. 
  2. Fatty acids require glycerol-3-phosphate to be stored as body fat. 
In other words: If you avoid eating foods that contains glycerol-3-phosphate and foods that causes your insulin levels to increase, your body is unable to store body fat. As I said, pretty important facts.

You might have heard about glycaemic load (GL). GL is a measurements for how quickly the carbohydrate in a particular food will cause your blood sugar levels to rise, or how aggressive a food is.

Here is another important fact: Starchy vegetables are quite aggressive foods and they also contain glycerol-3-phosphate, that is, the two substances that the body needs to store body fat. That is a really good reason to avoid them, I think.

Let's focus on what we can eat instead: You can eat all the non-starchy vegetables that you want. It is not possible to over-eat non-starchy vegetables because they are so filling and you want to eat so many of them that you are too full for starch and sweeteners (more about those soon).

So, just in case you are still not convinced, here are some of the reasons for eating lots of non-starchy vegetables:
  1. you avoid gaining more body fat
  2. you heal your body fat metabolism so that it works to keep you slim
  3. you reduce the risk of becoming insulin-resistant (type 2 diabetic)
You can read more about the two first points here, more about type 2 diabetes here and you can find a list over non-starchy vegetables in the Food list.

The above is based on Jonathan Bailor's brilliant book "The Smarter Science of Slim: What the Actual Experts Have Proven About Weight Loss, Health, and Fitness" (2012). Here is the link to www.thesmarterscienceofslim.com - it's never too later to reverse the damage to your body.

  1. Hi Rikke, great post. Is there a more complete list of starchy vegetables somewhere, I imagine potatoes would be there but unsure about a personal favourite like rutabaga (kålrabi) for example. Also the Skeptics in the Pub are having this lecture next Monday "Arne Astrup: Kost, hormoner og vægtregulering – fakta og myter" who has the book Verdens Beste Kur 2.0 with Christian Bitz, do you know this and if they are "preaching" the same stuff as i.e. scienceofslim?

  2. Hi Elfar. Thank you for the kind words :-)

    I have done a bit of research on the book that you mention and it does seem like they recommend something similar but with a more relaxed approach to grains, roots and chocolate - probably because they are trying to influence Danish food culture where these are extremely important! I will do some more research on this and get back to you.

    Rutabaga is a non-starchy vegetable but it is not on the SSOS list, probably because the water and fibre levels are too low to justify to put it there. I will also look into that. In the meantime, don't worry too much about it. I don't think an occasional rutabaga will ruin your slim features - the beer you are likely to drink in the Pub while listening to the lecture on the other hand... well... :-)

    More about all this later. Now I have to get some sleep.

  3. Hehe, yep, found it quite ironic to have this lecture in a Pub (a pretty strict beer only pub even) ;)

    Thanks for the feedback :)
