Journal · 25/09 — Korovljev 2018: visceral fat −4.9% in 24 weeks

Paul Fournier


The Serbian randomised trial on 60 overweight subjects. Detailed methodology + raw.

60 subjects. DXA. 24 weeks. A confirmed plateau.

Korovljev, Vukomanovic et al. 2018 (Journal of the International Society of Sports Nutrition) randomised 60 overweight Serbian adults (BMI 27-33) into two groups. HRW group (hydrogenated water 1 L/day, 7 ppm) vs placebo group (visually identical still water).

Primary measure: DXA body composition (dual-energy X-ray absorptiometry, gold standard). Secondary measures: waist circumference, fat mass index, fasting insulin, HDL/LDL cholesterol.

Result at T+24 weeks: −4.9% visceral fat in the HRW group vs −0.7% placebo (p=0.003). HDL +12.4% vs +1.1% placebo. Fasting insulin stable HRW vs +8.2% placebo (metabolic drift).

No change in diet or physical activity imposed. Subjects continued their normal lifestyle. The observed effect is attributable to the H₂ intake, at a protocol comparable to ours (750 mL/day vs 1 L/day in Korovljev).

Study no. 5 in the HYX corpus. Direct link below.
