Can't Say No

Having self control = success. Pretty simple. Get some willpower to just don't eat what you don't want to.

We all have that power. I don't accept people saying that they cannot do it.

Be careful: willpower is a finite resource. Using it requires a lot of cognitive energy, which ironically makes you look for high-energy foods. There are many studies on this subject.

You can use willpower to start, but it runs out eventually. I have been keeping my weight down for almost 3 years, and it's not thanks to willpower. Willpower is simply not a sustainable solution. What lasts is forming good habits, building helpful tools, and a true understanding of your motives. I am at a pickle now because I don't understand my behavior. If I could figure out why this happens I can find a solution to overcome it.

This is an excellent point. While it's true that some people seem to have an iron will and can just live that way indefinitely, most people will eventually cave in if all they do is continue trying to hold their urge at bay.

On another note, something that has worked really well for me is to get an accurate sense of the cost of some of these snack foods. For example, an oreo has 75 calories. So four of them is the same as a Haagen dazs bar. For me personally, there's no way that I'm going to enjoy 4 little oreos as much as the haagen dazs bar, so I'm just not interested in oreos anymore. That's just one example, but in the big picture, when you're faced with some tempting food, especially one that ultimately doesn't really taste that good to you, try to imagine something that you really do enjoy with roughly the same calorie count that you won't get to eat today if you fall for the temptation.
