I have recently started making a concerted effort to eat better due to high cholesterol. My BMI is in the normal range, but at the high end of normal.

Given my recent experience eating better, I think junk is probably even worse than many people realize.

Refined sugars increase appetite astronomically. When I flipped to healthy food, I had a good few days of "suffering" as my body adjusted to lower calorie intake. After that, I never felt better.

My daily calories are something like 1/4 what they used to be. I lost 10 pounds in a few weeks without even trying. My mental clarity is coming back, which I thought slipped a bit due to age. Maybe age is a factor -- but diet fixed it!
