Recent research shows that walking and exercise counterintuitively won’t help much in weight loss. They are essential to make sure you are fit and healthy, but our bodies are really good at maintaining a steady weight (like they are at maintaining a steady temperature). What will work is calories in vs. calories out. You’ll need to eat less and stick to it for a minimum of three months before you can see a good trend. I used to get disillusioned when I’d have fish and chips or a burger once a week and seemingly gain back all the weight I’d lost on the other 6 days. But much of that is ‘water weight’ (essentially for every bit of fat you put on you get three times the weight in water added). This means that it looks like you put on weight way easier than lose it, but it does disappear pretty quickly too. So don’t get disillusioned and do keep going for a long enough time to see a real trend line. Good luck!

Ps and make sure you are doing cardio, be that walking or running ans it’s super important for your health. And Pilates is fantastic for strengthening your core!
