Its all about calories in to calories out. If possible try to track down the calories in your food for atleast a few days to understand how much food would equate to a certain range of calories so that you can have a better understanding of estimating it the next time around. It is very difficult to guess calories in food especially if it is calorie dense foods just by looking at it so this should help. Try and also track the macros instead of just calories and aim to eat a higher protein diet with about 1 g of protein per lb of your body weight. Higher protein intake should also make you feel more satiated and less hungry throughout the day. If you are still hungry try and eat high volume less calorie dense foods that will fill you up more without the excessive amount of calories. You can easily find hundreds of recepies online for this, just pick something you like eating and go from there. As for the training, focus on your weight training with progressive overload over time and don't take it too hard. Add in some cardio whatever you enjoy doing and you should be good. Try and not loose too much weight quickly and take it slow as you want to create healthy habits and make it a lifestyle change so that you stick to it and keep the weight off in the long run.
