Palaeolithic diet decreases fasting plasma leptin concentrations more than a diabetes diet in patients with type 2 diabetes: a randomised cross-over trial.

The absolute level of glucagon at the end of the Palaeolithic diet was lower than at the end of the diabetes diet (moderate effect size, Cohen’s d = −0.51), but this difference did not reach statistical significance ( p = 0.089) (Table 2 ; Fig. 2 ).
