@leeosteo I have been playing with low/carb and keto, although not since about 2021 when my heart began to act up and I eventually needed two catheter ablations. And my girth has grown commensurately. A work in progress...

The science is still growing and arguing. I follow Dr. Rob Cywes on his YouTube channel, but have listened to countless lectures by Dr. Stephen Phinney and Dr. Nadir Ali, all high-priced, highly educated, some with two PhDs, and running businesses and giving lectures to cardiologists. They favour meats, dairy, lots of animal fats, even putting a pat of butter on a steak if it helps to ward off hunger pangs. Their science is impeccable. Then, others point to strong evidence that a Mediterranean diet is the way to go, and it is very strong indeed. I now follow the channels of only two people, both on Youtube: Nutrion Made Simple, Dr. Gil Carvalho, and Dr. Nick Norwitz. They seem to have a strong thumb on the pulse of things edible, and between them I get good information. I have not looked specifically for articles stating that animal fats are good or bad....but I believe that some if it is good. Plant oils must be of impeccable quality...and they must be fresh and used up within a few weeks of opening, refrigerated, or discarded after about three months. I learned this starkly two years ago when my wife had a mastectomy and our middle daughter came to be with us and get us through the rough patch. She baked some 'energy cookie balls' and they had some flaxseed I had in the fridge since Christ was a corporal. We both took one look at each other, hers quite accusatory, when we each bit into one of them. She grabbed the bag and looked at the long-since-murderous best-before date, and then waved it in front of me. I had to hang my head and agree I'd messed up. The entire batch had to be thrown into the bin.

Seed and plant oils are not necessarily bad, but they CAN be. Do your research about the best quality brands, and don't hang onto it more than about three months...even if it's in the fridge.
