Log-Minkowski inequality for centrally symmetric convex bodies

Let C,DConvs(Rn+1)C,D\in\mathrm{Conv}_s(\mathbb{R}^{n+1}) be centrally symmetric convex bodies of unit volume, and let hC,hDh_C,h_D denote their support functions. Let νC\nu_C be the cone measure of CC. Log-Minkowski inequality. One has

log(hDhC)dνC0.\int \log\left(\frac{h_D}{h_C}\right)\,d\nu_C\geq 0.

The inequality is related to an equivalent log-Brunn–Minkowski inequality. The source attributes it to prior work but gives no evidence of a resolution.
