Hi and welcome!!
I started my journey even later (& heavier) - at age 42.
I had HORRENDOUS, just horrendous eating habits. I gave up foods that I literally thought I couldn't live without. Trouble was, I wasn't living very well WITH them.
Making the decision to lead a healthy lifestyle was the best decision I have ever made. I was shocked and amazed at the things I was able to give up just upon DECIDING to give them up. I was even more shocked at how I grew to love and crave all the healthy foods that I ADDED in. Gave up some foods - ADDED in others. MUCH, MUCH, MUCH better ones. That taste fantastic and are fantastic FOR ME.
I'm sure you too will be amazed by this journey. Don't dread it. Get excited about it. Because it's an incredibly lovely way to live.
You CAN do this. I am certain of it. I look forward to hearing of your success!
