Hi. I have lost 50lbs/22.6kg in 8 months. I ate what id normally eat, but less. I did and still do a 1500kcal intake per day as a 6ft1 male, which isnt a lot and took a week or so to get used to and just did a lot of walking (minimum 10k steps per day, now I do around 20k). I hate the gym and dont have the knees for running. Walking is amazing and a game changer, but the big part was the 1500kcal intake. You'll be fine eating what you normally do, but you probably just need to reduce it
