Low-fat vegan diet cuts liver fat 33% and boosts beta-cell function in 16-week type 2 diabetes trial
A 16-week single-arm trial found an unrestricted low-fat vegan diet produced clinically meaningful reductions in liver and visceral fat alongside improved insulin dynamics in adults with type 2 diabetes. The study design limits causal inference but supplies detailed mechanistic data on ectopic lipid and beta-cell responses. Larger randomized trials with longer follow-up are needed to confirm durability and comparative effectiveness.
Next steps require a randomized controlled trial with an active comparator arm, 12-month follow-up, and cost-effectiveness analysis to test whether the observed 6.6% weight loss and 33% liver-fat reduction translate into lower rates of cardiovascular events or progression to insulin therapy.
VITALIS: A multicenter RCT of 200 adults will show the low-fat vegan arm maintains at least 0.7-point HbA1c reduction at 12 months versus control in ≥55% of participants.
