Pretty easy to say, harder to do. It's best to set up barriers like this to prevent overeating. Another barrier is eating foods with low calorie density. The barrier here is the harshness of the drink - it is very hard to chug scotch. It is not very hard to chug a beer.

When I don't want to eat a lot, I set up barriers. I have literally no food in my apartment. 0. I am a former fat person, who has gotten into shape purely by avoiding the need for willpower. I like this hack - I'll try it this weekend.
