I love sugar....but here's the problem with sugar...it's absorbed into the blood really fast (sugar spike), and tells your pancreas to make insulin fast, too. So your pancreas goes...OMG! Look at this rush of sugar, I'd better make a TON of insulin (insulin spike)!
But then, after the sugar is taken care of, there's insulin left over and blood sugar gets a little too low...which triggers your hormones to go...OMG, we're running out of food...we NEED more SUGAR!
So you end up with a biological craving for sugar...that makes you eat more sugary things...or other simple carbs like white bread or fruit juice...and the whole process starts over again:)
Round and round you go.
I try to be mindful of picking low glycemic carbs...sugars that will enter the blood slower...whole gains, etc.
For my really sugary stuff...fruit, milk, naughty regular sugar.....I am mindful of that boomerang effect. I eat small quantities and when I predictably get hungry again....I break the cycle with something low glycemic, or I just tough it out because knowledge is half the battle.
I get along great with Splenda. I hate Stevia...just tastes God-awful to me.
After sleeve I've noticed that if I try to eat too much refined sugar, I won't get true full-on dumping syndrome, but I'll feel a little nauseated and crappy...so maybe a touch of it. It's a good reminder and I'm happy to have it.
