Of course, if your protein intake is quite high, then this is less of a factor.
An consistent blood sugar profile seems preferable for a number of reasons beyond just "total" weight loss.

Muscle preservation is *mostly* (from my understanding) based on two things.
1. Adequate protein for the body to support and maintain current muscle mass
2. The "need" to keep muscle mass (putting the body under loads that requires the muscle).
There is ample evidence that people who weight train can maintain muscle mass during calorie restriction as long as adequate protein is maintained. People who use PSMF (protein sparing modified fast) diets are proof of that. I've even done similar things myself.
PSMF also works better than conventional dieting (given identical calories) for preserving muscle mass even without weight training.
Also, please keep in mind that, despite my posts in this thread, I DO NOT advocate eating a bunch of highly processed, high GI, high fat, whatever foods. My arguments are based purely on fat gain/loss and nothing else. General health is an entirely different topic and not always related to fat people. Of course eating more natural and unprocessed foods will be better from a health/performance stand point. Phytonutrients, micronutrients, and fiber all play a role in being a bad ass. On the other hand, if you're eating lots of fruits and veggies, lots of protein, and getting your healthy fats... eating a bowl of ice cream isn't going to make much difference as long as it doesn't exceed your caloric goals.
