I have several ancestors and family members who have lived past 90, and a couple past 100, and every one of them has eaten bacon and eggs almost every day of his/her life. Fat doesn’t make you fat. That’s all a big, fat lie, told by people who don’t want anyone other than the elite to eat meat (I’m on a rhyming spree!). Fat in the diet does not equal fat in the blood, or on the body.
The rise in obesity corresponds to the use of HFCS in everything, and everyone being told to eat more grains. High fat, high protein, and lots of complex carbs (fresh fruit and veggies) is the way to go. (And don't leave out lacto-fermented foods, too)
