NCT07075133

Brief Summary

The aim of TIMEDIAB is to demonstrate that early TRE (eTRE) combined to late (afternoon) exercise will outperform eTRE combined to morning exercise on muscle function as primary endpoint, and glucose homeostasis as secondary endpoint

Outcome Measures

Primary Outcomes (1)

  • Change in skeletal muscle function

    Change in skeletal muscle function, assessed by 30-CTS score at inclusion (baseline) and 12 weeks after diet/exercise program; This test is used to assess lower limb strength. The score corresponds to the total number of standing positions correctly performed within the allotted 30 seconds.

    4 years

Secondary Outcomes (21)

  • Change in muscle function

    4 years

  • • Change in M value measured by hyperinsulinemic euglycemic clamp

    4 years

  • Change in HbA1c, during an oral glucose tolerance test

    4years

  • Change in fasting glucose, during an oral glucose tolerance test

    4years

  • Change in 2h blood glucose, during an oral glucose tolerance test

Interventions

Standard antidiabetic diet

Diet control (no chrono restriction) + exercise performed in the morning

eTRE for a total duration of 12 weeks. During the eTRE, volunteers will have to eat and drink (meals + snacks, medication) exclusively during an 8-hour period which will extend between 6 a.m. (flexible: or 7 a.m. or 8 a.m.) in the morning and 2 p.m. (depending on the chosen start time: or 3 p.m. or 4 p.m.), which corresponds to a fasting period of 16 hours per day

Physical exercise will consist of 3 weekly morning sessions that will combine aerobic and resistance exercises
