You make a good point. The purpose of eating is to fuel one’s body. If one can enjoy the meal, that’s just lagniappe.
I eat a balanced diet. I am an active guy, even though I’m in my 70s. I don’t eat sweets or cakes or donuts or ice cream, or...well, you get the picture. I put on my plate enough to provide me with the fuel I need, and nothing more (I don’t “top off the tank”).
I'm learning to do that. My joke is that in order to lose weight, I'm forced to live on food and water.
