He went on to talk about the women's nutrition and healthy living study, which was a randomized controlled intervention trial involving 3,088 breast cancer survivors. Patients were followed longitudinally and the measurements repeated at the beginning of the study, 1 and 4 years. The clinical outcomes were breast cancer (7.3 years follow-up) and mortality (cancer-specific and general).
- The duration of the night fasting was estimated from food withdrawals with a timestamp.
- The recurrence of breast cancer was significantly lower in patients with nocturnal fasting of> = 13 hours than in <13 hours.
- HR for breast cancer-specific survival (fasting all night> = 13 hours versus <13 hours): HR 1.21, p = 0.19
- There was also no difference in overall mortality

After 1 month, they found the following results:

Although this was not planned (and the patients were not listed as potential benefit), they found a weight loss of 1 kg in one month regardless of the breed. The average nocturnal fast was 13-13.2 hours, based on 10.6-10.8 hours. There was no difference depending on the race.
More important:
- 90% said fasting was easy
- 90% said they could fast for more than 12 hours
- 70% said they preferred SMS over the phone.
- 90% found the fast something pleasant
Takeaway statement: Prolonged nocturnal fasting may be a strategy to reduce cancer risk, as well as excessive morbidity and mortality in cancer survivors.
