Inclusion criteria

Inclusion criteria: 1. Informed consent 2. Participating in a fasting week at the Centre Interlude Bien-être 3. Age = 20 years, = 70 years

Exclusion criteria

Exclusion criteria: 1. Diabetes mellitus or taking glucose-lowering medication 2. BMI <18kg/m2 3. Known eating disorders (orthorexia, anorexia, bulimia) 4. Known metabolic pathologies that contraindicate fasting (e.g. deficiencies gluconeogenesis) 5. Pregnant women or during the lactation period

Design outcomes

Primary

Measure	Time frame
Plasma LDL cholesterol (laboratory analysis in mmol/l) measured at the onset of fasting and two months after the beginning of the fasting week, in the group selected for blood sampling	—

Secondary

Measure	Time frame
1. Total cholesterol (mmol/l), HDL cholesterol (mmol/l), triglycerides (mmol/l), blood glucose (mmol/l), CRP (mg/l) and IGF-1 (ng/ml), in the group selected for blood sampling (laboratory analysis), and variation in BMI (kg/m2), CA (cm), TA (mmHg), heart rate (/min), temperature (°C), measured at the beginning of the fast and 2 months after 2. The same measures (and LDL cholesterol) at the beginning and at the end of the fast 3. Fat-free mass measured by bioelectrical impedance analysis at 50 kHz with Nutrigard MS performed at the beginning, end and 2 months after the beginning of the fast	—
