Remember the sham Snackwell cookies back in the 90s? They took the fat out and replaced it with sugar to keep the cookies moist. Same caloric count as the regular cookies made with fat.
Or they replaced the lard and beef fat..which are natural..out of the baked goods and replaced it with hydrogenated fats..which are chemically altered vegetable fats so they have a long shelf life.
It’s the sugar. Read Dr. Casey Means book.
