1) The comment: I'm just about to leave the following comment on Peter (Hyperlipid)'s blog post Insulin and the Rewards of overfeeding. I thought that it was so good at summing-up, I'll post it here first!
Insulin increases the amount of glucose & FFAs entering fat cells, muscle cells & the liver.
Insulin decreases the amount of glycerol & FFAs exiting fat cells & the amount of glucose exiting the liver.
Hyperinsulinaemia (which can produce sedation) results when one or more of the following tissues loses insulin sensitivity:- fat cells, muscle cells & the liver.
So, why do people keep saying that hyperinsulinaemia locks nutrients away in fat cells only, thus robbing other cells of nutrients, thus causing lethargy?
The relative insulin sensitivity of tissues determines the relative partitioning of nutrients into those tissues.
When tissues lose sensitivity to insulin, blood glucose control becomes impaired. This results in roller-coaster blood glucose levels after eating high-glycaemic carbohydrates. A rapidly-falling blood glucose level causes ravenous hunger. I have experienced this during medically-monitored tests (OGTTs & an insulin shock test).
Low-carb/ketogenic diets don't result in a roller-coaster blood glucose level and therefore don't cause ravenous hunger. Simples!
Overeating due to ravenous hunger is NOT gluttony, just as under-moving due to sedation is NOT sloth.
THIS is gluttony."
EDIT: This didn't go in my comment but should have:- "Low-carb/ketogenic diets result in the avoidance of moreish & calorific foods such as sweets, chocolate, cake, biscuits, pizza, Pringles etc. A single bite of such foods has a negligible effect on blood glucose & insulin levels, but encourages another bite and another and another ad nauseam, due to Food Reward.
2) The simile: I use similes. I used the simile "As happy as a pig in shit" in a comment somewhere on Woos blog. Now, you may (or may not) have noticed that my user-name is Nigeepoo. We Brits are obsessed by two things - The weather and our bowel movements. I find things to do with poo and farting amusing (schoolboy humour, I know!). I used the simile "As happy as a pig in shit" because it is amusing.
3) The insanity: According to Woo in the following comment:-
"Re: the comment...Sorry, not convinced.
You are basically refusing to admit your choice of words implied moral judgement. The phrase "happier than a pig in shit" is always applied to examples of people being content in immorality/bad behavior particularly gluttony and sloth... unless it is used ironically. Only an autistic or a non-english speaker would believe this crap."
Woo, you are as mad as a March hare. IMO of course, like everything I write. Duh!
