It's also a great way to keep yourself honest, because you'll enjoy wearing the newer, slimmer clothes more. If they start feeling tight on you, then it may be time to reevaluate what you've been eating... or stop drying your clothes on high.
How do you have a social life when you're trying to lose a ton of weight?
Easy! Your friends will be supportive of your newfound health efforts, first off. Also, we live in an age when almost all restaurants offer healthy options. Get a salad bowl at Chipotle instead of the burrito bowl. Order the hummus platter instead of mozzarella sticks as an appetizer. Rather than drinking, get high! No calories in weed! Both reefer and alcohol make people eat crap, so try to keep it under control, whatever your drug is. When going to parties, offer to bring something. That way you have control over at least one food item.
Get to know your city, and always look at menus online ahead of time. Suggest to your friends that you try a new restaurant with a healthier menu. If you're going somewhere that will surely have a tasty, but unhealthy menu, have a big healthy snack before you go. You'll make better choices when you're not operating on an empty stomach.
