There was an interesting article in my Toronto Globe and Mail this morning which suggests that not all calories are created equal. Some calories are just more fattening than others!
New research indicates that our bodies derive different levels of energy from different types of calories.
Low fibre, high Glycemic Index calories (for example, from white bread) are must more easily digested than high fibre, low Glycemic Index calories (for example, from leafy green veggies).
So: 100 calories is not always 100 calories when it comes to what gets deposited on the hips and around the middle. It depends upon how much work the body has to exert to digest a given 100 calories. Raw or unprocessed foods leave fewer net calories behind (or on my behind!)
Apparently the body doesn't much distinguish between highly processed corn flakes and highly processed white sugar . . . biologically, a bowl of sugar with a few corn flakes is processed pretty much the same as a bowl of cornflakes with a little sugar!
A long time ago I decided that white bread and white pasta and white potatoes all make me fatter than their calories counts suggest that they should. So: I pretty much stopped eating them.
Those huge lunch salads are way more satisfying, even if I adjust for portion size so that I'm comparing the same calorie count as, for example, a small cheese sandwich on two slices of bread.
I've gotta manage the metabolism I've inherited or acquired. I've gotta accept that some calories (the pre-processed ones) are just too easy for my body to grab hold of. And hold onto. And hold onto. And hold onto!
