Inclusion criteria: The inclusion criteria: aged between 20 and 60 years and a BMI of 25.0–35 kg/m2. The metabolic syndrome was diagnosed as having three of the following five features: waist circumference (=102 cm in men and =88 cm in women); try glycerol levels (=150 mg/dl); HDL-C levels (<40 mg/dl in men and <50 mg/dl in women); blood pressure (=130/ 85mmHg or on treatment for hypertension); glucose levels (=100 mg/dl. The ability to understand the study protocol and provide written informed consent. The exclusion criteria were as follows: an inability or unwillingness to participate; antibiotic treatment; more than 10% weight change over the preceding 6 months; recent (four weeks) changes in exercise intensity or frequency; nonconsumption of low-fat yogurts habitually; consumption of probiotic products habitually; intake of medications that could affect body weight, calcium or vitamin D metabolism; taking drugs for blood glucose or lipid control; taking multivitamin-mineral supplements, omega-3 and oral contraceptive peel; Allergy to probiotic or dairy products; smoking or alcohol consumption; serious medical illnesses including cardiovascular, gastrointestinal, cancer, neurologic, renal, hepatic, endocrine, rheumatoid, thyroid and eating disorders. We also excluded the pregnant or lactating women. We also made sure that the subjects had not participated in any other weight management studies within the last 6 months of screening. Other exclusion criteria during the study included: non-compliance to the study protocol; the occurrence of serious adverse events and any changes in intensity or frequency of exercise.
