Do you have to be a hermit to lose weight?

For me, losing weight would probably mean cutting back on my social life. I love my friends, but we rarely do much together besides drink beer and eat junk food, and I'm not brazen enough to insist that they all make healthier choices just because I have trouble resisting the urge to chow down on chicken wings when I'm around them. It seems the best strategy for weight loss would be avoiding the social scene, but what kind of a life would that be?

Diet Blog has some great suggestions for eating healthy and maintaining a social life. There are lots of strategies that you can use, but here's what works for me:

• Encouraging healthy habits in others, such as a going on a walk instead of an all-night drinking session in the pub
• Making healthy food for my friends and I to enjoy
• Saying NO -- to another beer, to a plate of nachos, and so on. And sticking to it.
  

What works for you?
