Similarly, changes in blood glucose and insulin levels caused by disturbed feeding rhythm will also affect the expression of the “circadian” related proteins (Mistlberger, 2020), and the impaired glucose tolerance and insulin sensitivity caused by disturbed feeding rhythm can be corrected by controlling eating time and changing dietary structure (Chaix et al., 2019; Crosby et al., 2019). This evidence concerns the gene INS and Impaired glucose tolerance.
