Honestly? IMHO, you bet it does if it's more than an occasional occurrance.

Think of your body as an engine. It needs fuel to function. If you do not give it what it needs you are going to impair it's ability to get the job done.

Yes, you should only eat until satisfied. Yes, you shouldn't be stuffing yourself. Neither of these will help you lose fat. Eating too little for your body to function will also slow down fat loss.

Centuries of evolution have left us with bodies that are very good at adapting to what we do to them. Feed it less and less and pretty soon it takes less and less to get the job done. Fat burning shuts down - its a safety mechanism from times when food was not plentiful and fat stores were needed to survive famines.

Your best bet is to eat smaller, more frequent meals throughout the day. You eat the same amounts of food - you just eat more often. The very act of eating raises metabolism.

If you've been LCing for a few weeks and you've noticed you're less and less hungry, and consequently eating less and less, you've probably also noticed that your losses have slowed as well.
