Key predictors of an increased likelihood of adhering to an eco-sustainable diet included being female (OR = 3.05, 95% CI [1.85, 5.03]), a greater preference for morningness (OR = 1.08, 95% CI [1.01, 1.14]), higher levels of Agreeableness (OR = 1.43, 95% CI [1.09, 1.86]), and increased Openness to Experience (OR = 1.60, 95% CI [1.23, 2.07]). Conversely, higher scores in Honesty-Humility (OR = 0.69, 95% CI [0.49, 0.97]), Extraversion (OR = 0.80, 95% CI [0.67, 0.96]), and increasing age (OR = 0.98, 95% CI [0.97, 1.00]) were associated with reduced odds.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Both chronobiology and personality traits may significantly influence an individual\u2019s inclination toward eco-sustainable dietary choices.
