A decent article and discussion about the "war on sugar". Lots of conflicting information related to diabetes and obesity and other disease.
From my standpoint, the WAP (Weston A. Price) diet principles allow for 30% or so of calories to come from carbohydrates. Some of those may be in the form of sugar (eg. glucose, fructose, lactose). Sugar in general is devoid of nutrients, like minerals and vitamins. The body requires vitamins, minerals, enzymes, fatty acids along with carbohydrates. It's more than just about calories. Anyway, I say enjoy something "sinful" on occasion and don't feel guilty about it. Lowering refined carbs does seem to help in losing weight. If you are diabetic, then special considerations need to be taken.
Healthy fats can replace sugar and helps reduce sugar cravings. Healthy fats are natural fats, from coconut and palm oils, to goose and duck fat, bacon, chicken skin and all those ones we're told are "unhealthy" by the "diet dictocrats" (credit Sally Fallon) and politically correct nutrition.
"A joyful heart is good medicine" (Prov. 17:22). Enjoy your food and I say be thankful. Life is out to get us no matter what. We can take control over what we eat.
