We've been running some basic experiments that suggest the opposite to these findings: http://hema.vu/1vA0sHR . But again, this is hardly conclusive (our sample size is much smaller).
Your experiment doesn't really look like the same thing at all. From your link, it doesn't look like you are controlling carbohydrates and your participants are just eating lots of fast food. The study started with low carb high saturated fat. I would argue that fast food is high carb and high fat. Interesting research though either way.
