Everyone is different, so you just need to experiment and see what works best for you and your body. But, I will share what has worked for me.
The first month or 2 I got an average of 500-800 calories. Not sure about protein or carbs since I didn't track those then. A few months out, I started to track on myfitnesspal.com, and that helps A LOT! I even have an app for my phone so I can enter foods when I am out.
In the last 2 months, I have probably ranged from 800-1200 calories a day, even a few "bad" days where I had 1500 calories. I usually range from 70-100g of protein, and anywhere from 70-210 carbs, most of the time its between 120-140. I don't restrict carbs and my nutritionist never suggested it. I do usually eat my protein first because that is what my body craves, but I do eat bread, rice, and Pasta. I think my weight loss has slowed down lately because I am snacking too much. You really have to watch that. I eat about 5-6 times a day, 3 meals and 2-3 Snacks depending on how active I am.
The first few months I did some walking, not much at all. But I was kind of active packing up my house to move and putting it in storage. I am not completely moved out, but I did a lot of packing and going thru a lot of stuff and getting rid of stuff.
I started working out about a month and a half ago. It was very rough at first, but I have worked up to a lot more, and pretty quickly. I haven't worked out in the past 2 weeks because I had bronchitis and it wouldn't go away! But, I am going to see how I do tomorrow.
Good luck to you and everyone in your journey's!! I feel like I am just begining it, even though I am half way to goal! I think losing is the easier part, keeping it off is the challange.
