Allie and JackieM: I completely agree that it is ideal to get the vast majority of your fat from the most healthy fat sources. But to add to anecdotal evidence….my choleterol is also in the excellent range subsequent to adopting a low carb lifestyle even with adding animal fats (am a bacon lover and my favorite steak cut is rib eye, the fattiest of the lot). Note the same result for M Mosely when he dropped his weight. He continued to eat a diet that included meat yet his cholesterol numbers improved with the intermittant fasting (the ultimate in low carb eating…no carbs no food).
Allie, your husband’s situation is a completely different matter…..of course you must exercise every caution. While he might safely eat some other types of fats, you absolutely are doing the right thing is serving him only the safest of the safe.
Each person if of course different with different genes and your own cholesterol / blood tests will dictate that path you take and how restrictive you need to be. That said…no more healthy oil that the olive oils (MUFAs) and avocados. How nice that they also taste so good.
