Picking Apart Glycemic Index: High Vs Low - PART I-




                Glycemic index has been of controversy, in terms of being a useful guide towards helping people lose weight. I won’t get into the whole origination of the glycemic index, or what was the reasoning for its purpose, simple because I feel everybody has heard something about it, and likely already factor it someway in the choices of carbohydrates they choose. My objective here is to provide you with the important points of my research, by giving you what is relevant, so you are left pondering. Giving you something to think about on the changes you need to consider to make, and how you can get your life back, (hint, hint, this is what my blog is all about) by getting the actual facts based on credible scientific research.

Insight on Glycemic Index and My Rant
                Before I begin, I feel though, I should give you atleast something regarding the glycemic index, and even if you never heard about it, than I encourage you to please listen up. This would be a brief explanation just to stimulate our brains to start thinking about the subject at hand more clearly. The glycemic index is used to see how significantly and fast a given food causes levels of glucose in the blood to rise. The belief was ALWAYS that low glycemic index keeps us fuller, improves our blood sugar, and stimulates a low initial insulin response due to improved insulin sensitivity. Sounds pretty much like an ideal scenario for fat loss, which it is mind you. All of this is in fact true, that the glycemic index do differ in glucose responses, and do indicate a difference in insulin responses, meaning low glycemic having a lower glucose and insulin responses, while high glycemic index have the opposite effect.  The problem here is the ALWAYS word I mentioned above. In fact studies actually show variances of both glucose and insulin responses. Meaning by eating either low or high glycemic index carbohydrates, will not support what you think should happen, and what I actually mentioned above is not always the case. Also consider that some studies show low glycemic index do keep us fuller, while other studies show no effect.

Ranting in General... Glycemic Index
Here is my issue with the whole problem, but also in this case the glycemic index, is giving your advice or answers in absolutes. That everything happens only this particular way, and the complete undermining of potential variances of responses is overlooked. We have to understand all potential variables, and if you are not able to understand that, than keep your advice general, but actually specify that, so people don’t feel they now know what happens, yet really have no idea. Sorry for the rant, getting off topic here, this is just something important for me to share, so we all realize on how important is to educate people with the correct information.

  1. i always wondered why diets are so general u'd think they'd vary on peoples needs, what do you think about canada's food guide tho where they say if your this age you should eat this and that without regarding any othe variables?

  2. Hey Jack.
    Well I will not really get into the whole debacle of canada's food guide. Yes I do think its a failure, once you look into the science of how certain foods are damaging once health. Mind you, Canada's food guide is advocating higher carbohydrate intake. Now we know majority of issues regards to cardiovascular disease, metabolic syndrome, autoimmune, and many other pathologies tend to be linked/correlated with either eating too much carbs. Grains have undergone much research, and are a major culprit too. I do think the guide should be treated as nothing more than a guide. Eventually you need to make educated decisions. Hopefully, I can be of service to help make a change in peoples lives.
