Losing weight isn't complicated once you understand how to do it, as previously said stick to a healthy diet whilst staying in a calorie deficit and exercise. Monitor your body weight on the scales but also use the mirror to see your progress. And my biggest tip would be don't give up! As you lose weight it's harder for your body to lose more and it can't maintain the same rate of weight loss so some weeks you might lose nothing, other weeks you might even gain a little due to weight fluctuations which is completely normal. Just stick at it and you will get where you want to be, it doesn't just take a couple of months, but stay dedicated and you will make progress.
