Background: CKDB-322, a combination of Lactiplantibacillus plantarum Q180 and Phaeodactylum tricornutum, has shown anti-obesity potential in preclinical models, although human evidence is still limited. This randomized, double-blind, placebo-controlled, 12-week trial evaluated the efficacy and safety of CKDB-322 in overweight adults. Methods: Participants were aged 19–65 years; had a body mass index (BMI) of 25–30 kg/m2, and a waist circumference of ≥90 cm for men or ≥85 cm for women. They were randomly assigned to receive either CKDB-322, which provided 1.0 × 109 CFU of L. plantarum Q180 and 200 mg of P. tricornutum daily (n = 50), or a placebo (n = 50). Results: CKDB-322 supplementation resulted in statistically significant reductions in body fat mass and body fat percentage, as measured by dual-energy X-ray absorptiometry (DEXA), compared to the placebo group (p < 0.05). Computed tomography (CT) analyses also revealed significant reductions in abdominal fat area in the CKDB-322 group (p < 0.05). Additional improvements were observed in body weight and anthropometric parameters. Among metabolic biomarkers, serum triglycerides and leptin levels decreased significantly in the CKDB-322 group compared to the placebo. Exploratory microbiome analyses indicated an increase in the relative abundance of Lactobacillus, suggesting potential modulation of the gut–adipose axis. CKDB-322 was well tolerated, with no clinically significant adverse events or laboratory abnormalities. Conclusions: Collectively, CKDB-322 demonstrated a favorable safety profile and produced statistically significant improvements in multiple adiposity-related outcomes, including reductions in body fat mass, abdominal adiposity, and key anthropometric measures, supporting its potential as a functional ingredient for body fat reduction and metabolic health.
