βHB, glucose and weight measurements. Blood ketone and glucose measurements taken at days 7 and 14 post-implantation show (A) higher βHB and (B) lower glucose in KD treated animals (C) weight measurements were taken every 3–5 days. Graph shows weights normalized to the average starting weight of each group. N = 12 for immune competent mice; N = 5 for CD8 depleted mice; student’s two-tailed t-test; *p
