Welcome! And congrats on the baby
I am new here too actually. I have lost 70 lbs so far - but still have plenty to go! Getting sick of eating the same things and starting some new ventures (clean eating and a month into a running program), figured I could find some new advice here.
A lot of my friends have asked me what the secret is and what I have told all of them was that - there isn't one. Let's be honest, there is no quick fix and losing weight is not easy, if so I'd be rocking my amazing goal jeans right now! Find what works for you and commit to it.
I will say what has worked for me is writing everything down. Yes, not always convenient, but it forces you to pay attention to what you are eating and the calories you are taking in. I HATED doing this in the beginning but I have gotten so used to it, its second nature to me. It helped me kick my worst habit, which was mindless eating.
My only other piece of advice - start today. I always said tomorrow but really "tomorrow" never comes. I said tomorrow for 20 something years and truly my only regret in my life was not doing this sooner.
Best of luck to you
