I've been following a LCHF diet since November which has been including coconut oil, gee, butter, olive oil double cream and Palm oil. I avoid processed food and starchy carbs, pasta, potatoes, bread, rice, wheat etc.
Overal for my diabetes its beneficial Hba1C is down from 52 to 41. So I'm now in the non diabetic range.
I've seen 2 consultants, and diabetic and rheumatology specialist nurses this month, all of which agree that the high fats and low carb approach is working for me, I think people react differently to food groups, the starchy carbs the NHS recommended were slowly killing me, weight gain and extra medication, bread and rice both have a higher GI rating than table sugar, but that is deemed OK by health care professionals.
Blood results this month were.
HDL cholesterol ratio 3.8
HDL is 1.12
Also 20kg weight loss since November.
All of which have been a massive improvement, some people are better suited to high fat rather than starchy carbs which are nothing but empty calories.
