I suggest you focus on adjusting a balanced diet, strengthening exercise, relaxing and ensuring sleep. The principle is that consumption is greater than intake. Have a good breakfast, 5-8 minutes for lunch and little or no dinner. Choose the proportion of three meals according to your physical condition. Losing weight requires both exercise and diet. It will take some time, so there is no hurry. Don't worry. It is most important to lose weight safely. Be careful not to use drugs indiscriminately to lose weight, and it will be troublesome to confuse endocrine. I hope I can help you.
