<I need to add this: fat storage is not all bad though because the body is
continually using it a source of fuel, at least to some degree, andespecially
during times of inactivity.Insulin is not our enemy either; it helps to build
muscle and every thingelse it's the overproduction that's the problem.>

That's right- as we know protein will induce a significant insulin response also, and this will still occur on the paleo diet. It is the massive spikes (and subsequent troughs) that we are trying to avoid (simple carbs.). Adaptation to a higher fat oxidation level, especially during exercise by athletes is now well recognised over the course of a few weeks. This is enzyme related, (increases in HSL breaks down fat in the tissues, and increases in LPL breaks down fat from the diet for energy) and therefore this fuel burning preference would persist at rest. (Hence training is a BIG part of the whole equation).

Getting back to fat and insulin, I suspect Markus's comments are related to a high fat AND carb. meal, in which case the insulin response post-prandial IS significantly increased (synergisitic). This is the bodies response to trying to make best use of the "feast" of fuel while it's there: Insulin will help store BOTH carbs and fat as fat in fat tissue.In fact insulin effects a "double whammy", as it also inhibits fat breakdown in the tissues.

If anyone can give a reference for research showing high insulin  response to pure fat I'd be very interested to see it!

-The main response demonstrated to increasing dietary fat levels is an increase in Lipoprotein lipase (LPL) which acts to break the fat down for either energy or storage - a GOOD thing if you're working on a higher fat % diet. Basically the whole fat breakdown-utilisation-storage- etc. cycle is kept running smoothly.

I think there still is a place for carbs (complex) in the diet, and following some of you other guys advice I'm now having a primarily carb / protein meal post-workout, in order to utilise the insulin for muscle replenishment. Otherwise I keep the carbs (and insulin) low through the rest of the day. (The slight sleepiness I get after this is ok, cos I'm going to bed soon after).
