I’ve used MCT oil extensively in the past. I used Twinlab’s emulsified mct oil when I was doing anaerobic conditioning work (high intensity, low duration) when I played rugby oh, like, 20 years ago (yeah it’s been around that long) using Depasquale’s Anabolic Diet.
It lessened, somewhat, the unpleasantness of that style of conditioning while in ketosis.
Somewhat being the key phrase, as it still hurt and performance was off.
I played games on Saturdays, and was fully carbed up for them, so performance when it mattered was high.
I’ve spoken about this before.
I found the process very interesting, as I started training for my season at about 240, and I dropped weight rapidly, being 220 when I started the season then hitting sub 200 at the end of the season and as lean as I have ever been (probably 11-12% bodyfat)
My conditioning for the game was excellent, except I’d gotten used to being able to hit and push with about 230 lbs behind me. At the lighter weight I was far more mobile and I was still squatting about 475 at the end of the season (power cleaning and push pressing 265 as well), so I was a super light, strong, and mobile. I typically played prop, but at the lighter weight I played 8 and flanker just as often.
