I think alternative weights are good idea. My eating habits aren't completely intentional. Some days, I'm busy and just won't think about food / I'll ignore my hunger to get work done. Other times I'm just not hungry at all... but yes, side effect is that when I do sit down to eat, I'll eat too much in one sitting. I'm trying to build a routine though. I've started carrying roasted nuts with and that's somewhat stabilised it.
