I don't have any baby tips (congratulations though!), but I struggled a lot for about eight months before getting it together.
The one thing that has made me confident and comfortable and much more certain about the chance for success is that I constantly focus on taking baby steps toward that which I aspire to.
First, I tackled exercise, because that is the easiest thing for me to add in. I just followed a program of online videos (FitnessGlo, but there are plenty of great vids on YouTube, too). I figured that equipment-free videos gave me no excuse - I could exercise in my apartment without shoes or a shirt

. The videos were 30-45 minutes and the only thing I committed myself to every day. It was stressful sometimes, because I was in such great shape at this time last year. I stuck with it and told myself to just be thankful for the new thing that I accomplished or did better than the day before.
About two weeks later, I decided to try focusing on my food a little more. Since I'd come up with a lot of excuses in the past, I tried to make it as easy on myself as possible. I prepped a few weeks worth of food and put it in the freezer. It gave me variety, saved weekday time, and made it impossible to say that fast food could really be faster (or tastier!).
Six weeks along into my exercise program, I decided I was bored with the videos and ventured into my own thing. I've been having a lot of fun tweaking things since then.
I think the single thing that has really been making me successful, after taking those baby steps of making success as absolutely easy as possible, was being mindful. When it comes to eating, that meant thinking about my hunger - if I wasn't sure, I made some tea, waited 20 minutes or so after finishing, then asked myself again. If I was feeling the urge to eat as many calories as possible, which was a real and constant struggle for me, I would do the same thing, or I'd gently remind myself that I had planned something wonderful and that the time for it was soon (usually within 10-20 mins). I'd focus on how excited I was about that thing I'd prepared until I could get to it. When I ate, I'd focus on my satiation level and how much I was truly enjoying the experience of something I'd prepared. This was a huge contrast to my previous behavior of scarfing down the cheesiest, potatoiest, deep friediest thing I could find in response to stress/having long intervals between meals (which is a stressor for my body).
In regards to exercise, I also treated myself gently. I tried not to focus on where I'd been in the past, and instead marveled on each new accomplishment or feeling or on even just getting out of bed to do my scheduled workout. I thanked my body and tried to respect it and focused on giving as much love to myself for whatever tiny reason I could think of.
All that helps me to celebrate early and often. Eat a few more veggies today? Yay! Do a quick workout after a happy hour? Go me! Eat or exercise consistently for two weeks in a row? Better break out the streamers!
I do apologize for the long post, but I hope that you can find in it some strategies to help you achieve what you're after. In sum:
1) Baby steps (small goals) 2) Make it easy 3) Celebrate early and often
Good luck, and strong will!
