I low carb with moderate fats, fatwise I stick to extra Virgin olive oil, oily fish, nuts etc. My cholesterol including my trigs went up when I eat low carb high fat, when I changed to moderate fats, cutting down massively on saturated fats it went down.
My blood pressure which was a high normal went right down when low carbing.
Without being too personal do you have any weight to lose?
If you do read up about the Newcastle diet.
