I eat around 1, 200 calories per day my BMI is 22. Is this a good way to get it lower?

I eat around 1, 200 calories per day my BMI is 22. Is this a good way to get it lower?

To lose weight you need to burn more calories than you consume. It is not likely that you can sustain a diet less than 1200 calories daily, so the better answer is to do more exercise and burn more calories. ...Read more
