Is the "Eat More Fat" Prescription Too Vague?

Answered on August 19, 2014

We know that it's possible for a high fat, low carb diet to facilitate the loss of body fat because there are tons of testimonials from people who have gotten quite lean doing it. We also see quite a lot of people who've encountered a body weight plateau. Though I'm not particularly fond of HF/LC, I wonder if the fat loss stalls are because people are increasing their intake of long-chain fatty acids that just get dumped into adipocytes instead of medium-chain fatty acids (which may never get stored in adipocytes, but I'm not certain of that). The difference between coconut/palm fat (Which is something like 2/3rds MCTs) and bacon fat is significant in terms of metabolic rate and thermogenesis.

Instead of focusing on the degree to which a fat is saturated, perhaps we ought to focus on the chain length. I'm fairly certain that excess stearic acid is treated the same as excess linoleic acid and just gets stored as body fat.

I wonder if those who are stalling out would benefit from simply shifting a lot of their fat intake toward coconut oil or solid coconut. I would test it out myself but I don't eat HF/LC and I'm allergic to coconut.

I think most agree with this on principle, but if you're on this site there's really no point but to sweat the details...

I think we should focus on calling fats by their standard names - linoleic, linolenic, stearic, oleic, palmitic - and drop the pop diet names altogether. Omega and PUFA? Thank you Betty Cracker.

It matters on the type of fat. Limit PUFAs, eat mostly saturated fat. MUFAs tend to fall somewhere in the middle.

Fat in general seems to be handled with a glove by the body, whereas carbs (especially fructose) mimics fat in many ways, without the benefits. The reason CO MCTs help with weightloss is because they are broken down into ketone bodies, which is the same process that occurs in low-carb diets. When the body is low on carb reserves, it will utilize ketones as energy and the process of ATP production becomes more efficient than in a non-ketogenic state.

MCTs are special in that you don't HAVE to be in ketosis to utilize ketones, because of their chain length.

As for short chains, I'm not 100% sure on this so don't quote me, but I believe Cordain has written something about how short chains are produced by intestinal bacterial fermentation from both long chain triglycerides and medium chain triglycerides. Supposedly acetic acid (vinegar) is a short chain triglyceride which might explain why many people who add apple cider vinegar to their diet find that their blood sugar remains more stable and they are able to lose a bit more weight.

Travis, can you handle Ghee? It, like coconut oil, is high in MCTs. What about a test of results from a ghee inclusion diet to replace other longer chains? I work with Dr. Ron Rosedale and he believes that the MCTs are far easier to burn. He recommends them to train your body to burn ketones. He is not anti SAT fat, his program has you wait till you can burn ketones before introducing SATs back into your diet. Please post the results if you decide to give it a try.

I think my question is do we really need to micromanage it to that degree? I worry that everyone is getting so caught up in the details that they are forgetting to enjoy life. I'm not averse to tweaking it to make things work, but at what point does it become an unhealthy obsession? Not trying to judge anyone here. If you are enjoying the intellectual challenge of figuring it out, that's great. I just think at some point we all need to relax and just live, you know? That's my ultimate goal. To be healthy and enjoy life.

I think we should explore in more detail for sure.
