Cortisone as an oral drug is another common culprit (e.g. Prednisolone). Cortisone often causes weight gain in the long run, especially at higher doses (e.g. more than 5 mg Prednisolone per day).

Asthma inhalers and other local cortisone treatments, like creams or nose sprays, hardly affect weight.
"Only doing abdominal-focused workouts, like crunches, won’t help you banish the bulge. Belly fat is simply where your body stores energy, so you need to take a whole-body approach to tackle it.

Squats, burpees and treadmill sprints are all examples to try." https://www.youtube.com/watch?v=eXyOlGTT9QE
Eat a 500 calorie deficit. To lose weight, you should calculate how much calories you're burning per day and eat around 300-500 calories less than that. However, be careful not to restrict yourself too much. On average women should eat no less than 1500 calories a day and men no less than 1700. You must be careful with this! You should not starve yourself; that will make you sick and feel miserable.
