Best comment I've read the entire thread - people don't realize that the GI of carbs is the most important factor to weight loss. Managing blood sugar and keeping a steady, non-spiking blood sugar level will result in pretty much automatic weight loss, without even having to diet.

My snacks are usually a small handful of almonds and a piece of fruit. Also, you can combine a somewhat high GI fruit like an apple with a handful of nuts, and the fat content will end up lowering the speed at which your body will absorb the sugar from the fruit, which evens out your blood sugar level. There are other fibrous foods that will do this as well.
