Ketofest Cholesterol Experiment – The Hypothesis

As detailed previously, participants of this experiment will consume food in two stages:

  1. Low Days – Low calorie consumption or fasting for three days, while still at a low-carb, high-fat ratio (LCFH diet) : July 11th, 12th, and 13th
  2. High Days – High calorie consumption for three days, while still at a low-carb, high-fat ratio (LCFH diet) : July 14th, 15th, and 16th

Cholesterol tests will be taken on the morning of the day following each stage.

Following the second phase of higher dietary fat, I predict the resulting LDL cholesterol for the majority of participants will show a decrease when compared to the first.

Hey Dave,

Just stumbled across your work and as a hyper-responder myself I have to say I am very happy that you have put some much thought, effort and dedication into this. Amazing work!

I’ve been doing some experiments myself but not to the level of detail as you. I have missed the one you are posting about here but I’ll definitely look to get involved in one shortly.

I’ve documented my experiences to date on my own website; if you could take a look at the below article when you get a chance I would be very grateful although I do understand that time is precious.

To summarise, at my peak, my Total-C was 455 mg/dl. My GP wanted me to get onto statins immediately but I promised her that I could make a dramatic improvement in a matter of weeks. I stayed keto but cut out one thing: a keto coffee. After two weeks my Total-C was only slightly over 300 mg/dl. My GP was speechless.

Anyway, would love to here back from you. Here’s a link to the post in question: http://ingfit.com/ketogenic-diet-cholesterol-part-1/

Best, Lee

It may be the butter in the coffee, not the MCT oil, that is causing the LDL spike.

Hi Doug, thanks for taking the time to post here. I created my own version of the keto coffee which only used coconut oil and MCT Oil Powder so it can’t be butter. Planning on isolating it in an experiment shortly so will post results 🙂 Cheers, Lee

Fascinated reading the exchange between you and Dave–thanks for sharing it here. May I ask what you use for your fats, i.e. in cooking, etc. Did you cut out coconut oil/mct oil across the board or just the extra ‘bombs’ in your coffee?

I just ran across a similar experiment in pubmed where a high energy meal before the next morning blood draw lowered LDL-C. They blamed it on the Friedewald equation failing in the case of a high calorie prev meal.

They used carbs to raise calories, rather than fat.n Of course the difference is nothing like what you’re observing, but it’s only one meal. I thought it was interesting.

Dave,

My total cholesterol hangs basically around 240-260. A couple of years ago I stopped at my office before going for my lab work (for which I had dutifully fasted), and had a cup of coffee with cream. I didn’t realize what I had done until I got to the lab and the phlebotomist asked if I had fasted. I said yes, but then made a mental note that, oops, I had the cream. When I got my lab results back, I was blown away. The total cholesterol was 194. First time in decades it had been that low. I am guessing it was the cream.

I will have to try the cream experiment again.

Karen,

I did that once, too. My doc told me “we’ll adjust for that” (not that they know how).

Depending on the timing and the amount of cream, there might be some extra trigs and cholesterol in Chylomicrons. So if anything, I’d expect your TC to be slightly higher. A few other things can lower cholesterol though, like exercise.

Those extra trigs would cause your calculated LDL to be lower, since the formula assumes you shouldn’t have any of those. I’d be interesting to look at the full lipid number if you still have them.

Regards,
Craig.

Craig,

I will dig out my numbers. But yes the trigs are a problem.
