I was diagnosed with diabetes, Hashimoto's thyroiditis, and a vitamin D deficiency on October 2:
A1c 7.2
Weight 197.3 lbs
cholesterol 231 (High)
HDL 46 (Normal)
LDL 151 (High)
Trig 171 (High)
VLDL 34 (Normal)

158 days later:
A1c 5.7 (normal)
Weight 154.4 - 24.4 lbs to go to my goal
Cholesterol 173 (normal)
HDL 55 (normal)
LDL 99 (normal)
Trig 94 (normal)
VLDL 19 (normal)

Guess that answers the frequently asked question about whether relatively high fat (60-80% of my daily calories including significant quantities of saturated fat), has a negative impact on my cholesterol . . .

(I'm eating fewer than 20 net carbs in any 3 hour period, with a target of 60 grams of protein/day, and a calorie limit of 1200.)
