Kickstarting a healthy diet / lifestyle?

[aspiringnurse]

Hello,

So in a bid to have a much healthier lifestyle (lockdown weight gain is increasingly rising
How do I kickstart a healthier lifestyle and diet?
No allergies and an occasional meat eater (I don't smoke either and don't usually drink)

Any tips and advice on how to maintain a healthier lifestyle and a better relationship with food?

For many years I have been on WW, SW etc etc and after having DS a year ago I'm heavier than I've ever been - I don't want another Summer feeling like

TIA!!

I've just started an app recommended by a friend, Healthy Plan by Ann - it's by the Polish athlete/nutritionist Anna Lewandowska. Other than a crappy day today I've been getting on well with it, the meals are planned for you and pretty straightforward, I feel better after a week of using it so I'm going to do my best to stick with it but I have similar problems, fall off the wagon a lot!
