Background: Obesity is a socioeconomic problem, and visceral obesity, in particular, is related to cardiovascular diseases or metabolic syndrome. Fermented grains and various microorganisms are known to help with anti-obesity effects and weight management. Studies on the relationship between Bacillus coagulans and anti-obesity effects are not well known, and studies on the application of fermented grains and microorganisms to the human body are also insufficient.

Objectives: This study aimed to evaluate the efficacy of Curezyme-LAC, an ingredient mixed with six-grain types fermented by B. coagulans, in reducing fat mass in adults with obesity.

Methods: In this randomized double-blinded placebo-controlled study, 100 participants [aged 40-65 years; body mass index (BMI) ≥ 25 to ≤ 33 kg/m2) were randomly allocated to two groups: 4 g/day Curezyme-LAC administered as a granulated powder or placebo (steamed grain powder mixture).

Results: After 12 weeks, visceral adipose tissue decreased significantly in the Curezyme-LAC group compared with that in the placebo group (mean ± standard error, SE of -9.3 cm2 ± 5.1) vs. (6.8 cm2 ± 3.4; p = 0.008). Compared to the placebo group, the Curezyme-LAC group also showed significant reductions in total fat mass (-0.43 ± 0.24 kg vs. 0.31 ± 0.19 kg, p = 0.011), body weight (-0.4 ± 0.3 kg vs. 0.3 ± 0.2 kg, p = 0.021), BMI (-0.14 ± 0.12 vs. 0.10 ± 0.07, p = 0.028), and waist circumference (-0.6 ± 0.2 cm vs. -0.1 ± 0.2 cm, p = 0.018) without a change in dietary intake and physical activity.

Conclusion: Curezyme-LAC supplementation for 12 weeks may benefit individuals with obesity by reducing visceral fat mass.
