I can give you some advice to help you lose weight quickly within 30 days after delivery. But please note that everyone's physical condition and recovery speed are different, so please consult your doctor before starting any weight loss plan.

1. Reasonable diet: Choose a balanced diet, including vegetables, fruits, whole grains, lean meat, low-fat dairy products and healthy fat. Avoid excessive dieting or skipping meals, as this may affect your energy and nutrition intake.

2. Control food intake: Try to avoid overeating, especially high-calorie and high-fat foods. Try to eat several times to avoid overeating.

3. Increase the amount of exercise: under the guidance of a doctor, gradually increase the amount of exercise. During postpartum recovery, you can start with light aerobic exercise, such as walking or yoga. With the gradual recovery of the body, the intensity and frequency of exercise can be gradually increased.

4. Breastfeeding: If it is breast-feeding, it will help to burn excess calories and promote uterine contraction. At the same time, breastfeeding is also good for your baby's health.

5. Adequate sleep: Sleep is very important for physical recovery and metabolic regulation. Try to arrange reasonable rest time and ensure 7-8 hours of sleep every night.

6. Drink plenty of water: keeping your body hydrated is very important for your new mother's health and metabolism. Drinking enough water can help digestion, detoxify and control appetite.

7. Avoid stress: Postpartum stress may lead to weight gain or difficulty in losing weight. Find ways to cope with stress, such as relaxation techniques, meditation or seeking support.

The most important thing is to give yourself enough time to recover and adapt to the new role. Don't excessively pursue rapid slimming, but pay attention to a healthy lifestyle and the overall recovery of the body. Remember, everyone's body is unique, please make a plan that suits you according to your own situation.
