My best habit

I think this is a great topic! My best habits right now are that I only drink calorie-free beverages (unsweetened iced tea, water), unless its a cheat day, or I've exercised my butt off and can afford the calories in a beer. I also log EVERYTHING, EVERY day so that I can see exactly where I went wrong or can notice trends (like this week is a super processed-food heavy week since I'm house-sitting and not really cooking fresh foods/buying my usual groceries, but going with peanut butter sandwiches and frozen dinners for the most part). I have also found that setting a goal that includes a set workout plan, such as a 10K with an 8 week training plan works really well to keep me focused.

Added lots of color to my diet (fruits & veggies).

Stopped allowing myself to use emotions and feelings as an excuse to make poor food choices.

Stopped looking at is a weight loss effort (been there, done that too many times) and started looking at it as a lifestyle change.

Stopped obsessing about what "I can't" do and focusing more on what "I can" do.
