Fat loss=calories burnt>calories consumed.
So either cut the amount of calories you eat or increase daily activity.
You honestly don’t need anything complicated it can be as simple as going out for a jog for 30 mins at whatever pace you can. Do this consistently for 4/5 days a week and as you get fitter increase the pace and distance you run.
For your diet reduce calories... if you use full fat milk maybe try semi skimmed. Reduce fats. Butters oils nuts etc and reduce sugars. Sweets, cereals, sauces and juices.
You’ll therefore increase calories burnt and lower calories consumed which will help you lose fat. Consistency is key and don’t start too strict with your diet or exercise as it’ll be difficult to keep up. Be patient and keep at it.
Good luck !
