Probiotics Cut Weight and Fat in Obese Adults.

In 2024, Belén Torres and a team from Spain reviewed six clinical trials from 2012–2022 involving overweight or obese adults. They studied how probiotics, like Bifidobacterium and Lactobacillus strains, affect body weight, BMI, and fat mass without dieting, using data from PubMed, Scopus, and Cochrane databases.

Probiotics led to significant weight loss in 66.6% of studies (about 1-2 kg), reduced BMI by 0.5-1 kg/m², and cut waist circumference by 1-2 cm in 80% of studies. They also lowered total body fat by up to 1.5%, improving gut health and metabolism without major side effects.

Take a daily probiotic with Bifidobacterium or Lactobacillus to help manage weight and fat.
