Well, I’d recommend a fitness tracker to start, so that you can start tracking your calories burned and your health goals.

Have you been able to eat all the food you want lately?  That's an important step in working out.

I have been gaining weight and want to start exercising.  How should I begin?
user
I’m really glad that you’re taking a step in the right direction.  I recommend getting an exercise tracker and tracking your activities.  Once you get a baseline, I can help you figure out how many calories you need to burn every day to stay healthy.

I was thinking about just starting out with walking a couple miles every day.  Would that be a good place to start?
user
Wow, that would be great!  But let’s start with a baseline, just to be sure.  How many calories are you burning every day?
assistant
I'm not sure how many calories I burn every day.  I've been really sedantary lately.
