'Metabolic Advantage' and why the First Law of Thrrmodynamics does not apply
I was going to post this elsewhere, but it deserves it's own thread. Highly useful information for any dieter to make an informed choice on their plan.

I'm not sure if the following comment is going to make sense in this conversation or just be like of the wall but ..
I was looking up studies regarding diabetics and diet, and there have been studies showing that diabetics on low carb diets not cal restricted lost significantly more weight that those on low cal diets..I know I'm leaving out the details, and not giving my source...if you have access to Medline database for any reason, search it...maybe a googel search will turn up what I'm talknig about. Anyway I'm done with cals in cals out, studies are showing carbs (not fat) as once thought are the culprits behind various diseases like heart disease and high BP... |
Yes, that is absolutely true and I've looked at some of those studies and their abstracts, myself. That is what the actual blog is about, at least in part - that one of the reasons lower carbohydrate plans cause increased weight loss is the thermic effects of feeding and that, while calories count, the composition of those calories makes a difference in the rate of energy burned and the amount stored.
The human body responds to different nutrients differently - the chemical reactions are just not the same from a Twinkie or a steak, and it is generally more resilient bodies with higher insulin sensitivity that can claim that to be so in any meaningful way. Data, and the strength of that data, is not on the side of "a calorie is a calorie". |
Totally agree that the data doesn't support a "calorie is a calorie". For metabolically healthy people - it is a close approximation - but for anyone with any sort of metabolic issues (i.e. insulin resistance) it doesnt work anymore.

Can't really express fully enough how grateful I am that someone broke the code on 'calories in - calories out. ' That theory fails to take the body's hormonal functions into account. In my case, insulin resistance means I am extremely carb sensitive. Without taking that into account, weight loss is a real struggle. I am 51 and have tried many methods. Nothing works for me like a low carb approach. Annik |
Another good site is here -- link opens to one of many interesting articles about weight loss + low carb approach

And contrary what naysayers will say - it doesn't "break" the law of thermodynamics. It's just that the nature of calories in, influences hormones, which then CHANGES the calories out. The standard paradigm treats calroies in and calories out as independent things - whereas, the food in actually influences energy burned.
