Brief Summary

This retrospective clinical study examines the impact of the longevity diet and fasting-mimicking diet (FMD), either alone or combined, on body composition and health indicators. Focused on subjects from the Valter Longo Foundation (2019-2024), the study aims to evaluate their effects on body fat percentage, lean mass, muscle function, and lipid profiles. The longevity diet, rooted in centenarian dietary traditions, emphasizes isocaloric meals with a balance of complex carbohydrates, unsaturated fats, and plant-based proteins. FMD involves a 5-day highly hypocaloric vegan diet to simulate fasting benefits. Hypothesizing that a return to a modified Mediterranean diet or incorporating FMD could improve overall health, the study spans diverse cohorts based on intervention type, duration, obesity level, and physio-pathological status. Data, collected from electronic medical records, will undergo statistical analyses to compare pre- and post-intervention measurements, exploring outcomes across subgroups. Ethical considerations, including de-identified data and informed consent, ensure compliance with clinical research regulations. In conclusion, this study provides valuable insights into the potential health and longevity benefits of the longevity diet and FMD, with implications for public wellness.

Outcome Measures

Primary Outcomes (1)

    Comparison of Free Fat Mass in percent at baseline and after a period between 3 months (minimum) and 2 years (maximum)

  • Waist Circumference

    Comparison of Waist Circumference at baseline and after a period between 3 months (minimum) and 2 years (maximum)

  • Hips Circumference

    Comparison of Hips Circumference at baseline and after a period between 3 months (minimum) and 2 years (maximum)

  • Total Cholesterol

    Comparison of Total Cholesterol maximum 6 months before the first consultation and maximum 6 months after the last consultation

Interventions

The longevity diet generally consists of three isocaloric meals and one snack (for normal-weight individuals) or slightly hypocaloric meals (in the case of overweight or obesity). The diet consists of 50-60% of calories from complex carbohydrates, 30-35% of calories from mostly unsaturated fats, and 10-11% of calories from proteins, primarily from plant sources and fish, and occasionally from eggs, dairy, and meat, especially for those over 65. The diet is formulated to provide all necessary nutrients, including vitamins and minerals. The fasting-mimicking diet is a dietary intervention in which normal food is replaced with a standardized, highly hypocaloric vegan diet for a limited period of 5 consecutive days. This diet is designed to stimulate the same processes normally activated during fasting while minimizing the side effects of total food deprivation.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

The bioimpedance, anthropometric, and clinical data of subjects who underwent at least one of the two nutritional interventions (individually or in combination) at the Valter Longo Foundation in Milan from 2019 to 2024 will be retrospectively analyzed. As this is a purely observational (retrospective) study with purely descriptive objectives, a formal power analysis estimation has not been conducted. However, considering that the Valter Longo Foundation in Milan is a regional reference point, it is estimated that approximately 250 subjects will be recruited retrospectively.

You may qualify if:

  • Healthy patients and/or those with diseases, excluding neoplastic and neurodegenerative pathologies;
  • Age \>/= 18 years;
  • Body mass index \>/= 18.5 kg/m2;
  • At least two visits, both characterized by bioimpedance and anthropometric analysis;
  • At least 3 months between the first and last bioimpedance and anthropometric analysis;
  • Signature of informed consent and privacy for the conducted visits.

You may not qualify if:

  • Age \< 18 years;
  • Lack of informed consent or privacy;
  • Women who are pregnant or breastfeeding;
  • Patients affected by oncological and/or neurodegenerative pathologies.
