Investigational drug(s) / intervention(s)

Multi-Professional Guided '5+2' Intermittent Fasting: An intervention team of dietitians, doctors and nurses gave patients specific dietary instructions online and offline. Dietary intervention according to the current research basis, intermittent fasting is mainly adopted, that is, the "5+2 light fasting" mode, in which 5 days in a week are non-fasting days, and the other 2 non-consecutive days are fasting days. The recommended daily energy on non-fasting days is based on body weight: standard body weight (kg) ×20; Or according to body composition measurement lean body mass calculation: BMS =370+21.6× lean body mass (kg), recommended energy intake = BMS × (1.2 \~ 1.3) -500, including protein 20%, fat 25%, carbohydrate 55%. Fasting day energy intake is 1/4 of the usual, about 500 \~ 600kcal.

Low-energy Balanced Diet: The target energy intake for women is 1000-1200 kcal/d. Adopt a balanced diet, in which carbohydrates account for 55% to 60% of the total daily energy, fat accounts for 25% to 30% of the total daily energy, protein 10% to 15%. Increase your intake of fiber-rich, low-energy foods to ensure you feel full.

Routine Care for Self-weight Management.: The relationship between overweightness and obesity and endometrial cancer risk was explained to patients in the control group and their willingness for self-weight management was respected. Communication was maintained with patients from treatment initiation to 6 and 12 months after treatment; patients' questions regarding weight reduction were answered and suggestions were provided regarding nutrition, exercise, and lifestyle management.

Study summary

In this study, overweight and obese patients with endometrial cancer treated with fertility- sparing therapy were randomly divided into three groups. The first group was given Intermittent fasting, the second was given Low-energy balanced diet, the third group underwent routine care for self-weight management. Relevant information such as body morphology ,glycolipid metabolism and tumor outcomes of the subjects were collected. By evaluating the tumor outcome and changes in glycolipid metabolism indicators, to confirm the effectiveness and safety of diet interventions for overweight and obese patients with endometrial cancer and treatd with fertility preservation.
