Hi Kristen! Something that really helped me was setting a non-weight number goal. My goal was to run a marathon. I started a training class in January and needed to eat healthier and lose weight to reach the running goal. The class started out really slow, so I was able to complete each step of that goal as I lost weight....if that makes sense.
Anyway, almost 50 pounds later, I ran the marathon this past Sunday and it was awesome!
It really helped me to have a physical goal that I needed to lose weight to get to. Since you mentioned dancing, maybe you can set some sort of dance goal. We have adult dance classes by me. Maybe you want to dance in the recital next spring? Start stretching and writing out some choreography you would like to do again. Or maybe dancing doesn't interest you anymore, but you always wanted to see the view from a local summit hike. You can just start walking up the hill in small amounts and as you lose weight you will be surprised at how much farther up the path you can go each week. I found this type of goal very motivational.
Lastly, the diet method that I used (and EVERYONE is different) was to eat small meals throughout the day. I found that this really worked for me as a diet and as a new lifestyle. I love to graze all day and constantly used to eat out of boredom. So when I first started and I was still in the bad habit of eating when I wasn't hungry, it was ok....because I ate some carrot sticks and hummus and it was allowed on my diet plan. Then I could eat again in an hour or 2 anyway and not blow my calories out of the water.
You will find your grove and a plan that works for you. Listen to everyone's suggestions and just understand that you need to find what works for your lifestyle and your goals. Being here and being accountable is a great step though! Best of luck! (and sorry I am rambling, but I had COFFEE this morning!!)
