These are pictures my husband took at our local grocery store. There is a mountain display of soda, snacks and other junk for Super Bowl weekend coming up.
Fructose undermines these normal satiety signals, increasing caloric consumption both directly and indirectly:
Fructose does not stimulate a leptin rise, so your satiety signals are diminished.
Glucose suppresses ghrelin (the hunger hormone—it makes you want more food), but fructose does not.
By raising triglycerides, fructose reduces the amount of leptin crossing your blood-brain barrier.
Fructose increases insulin levels, interfering with the communication between leptin and your hypothalamus, so your pleasure signals aren’t extinguished. Your brain senses starvation and prompts you to eat more.
Fructose decreases the production of malonyl-CoA, which may help promote a sense of energy adequacy.
Along with causing insulin resistance, fructose alters the hedonic response to food thereby driving excessive caloric intake, setting up a positive feedback loop for overconsumption.
So, have you managed to eliminate all of the artificial stuff from your meals? That is going to be my focus over the next week. I'm going to plan my meals and prepare so I'm not tempted to eat out and grab that soda. I want to live a healthy, full-of-energy life. After all, I'm here for a limited time only.
Do you ever get this feeling you want to move forward but are pulled by opposing forces? I have been very dismayed lately about how high fructose corn syrup is in EVERYTHING.
