Eat more vegetables and less greasy meat for lunch.
3. Have porridge for dinner.
Exercise:
Run (jog) for 45 to 90 minutes every morning, continue jogging in the evening when you have time, and stick to 10 km every day.
You can lose 5 kilograms in less than a month. The key is to be "hard" on yourself. If I don't insist, I'll say for nothing that I lost 4 pounds a month before. If you want to lose weight, don't practice sit-ups and other anaerobic exercises. Aerobic exercise is most suitable. Skipping rope in each group 100, 8 groups rest every day 1 minute. Pay attention to replenish water. I believe you will have more endurance than me.
