Can taking probiotics change your body into a slimming-prone type?
Consuming probiotics does not directly transform a person into a slimming-prone body type; they can only assist weight management to a certain extent. Detailed analysis is as follows:

The primary function of probiotics is to regulate the balance of intestinal microbiota and improve digestive and absorptive functions. Some studies suggest that an imbalance in gut microbiota may lead to disordered nutrient absorption, thereby increasing the risk of overweight. Supplementing with appropriate probiotics can help maintain the dominance of beneficial intestinal bacteria, promote food digestion and breakdown, reduce the accumulation of unabsorbed nutrients in the gut, and may also inhibit the absorption and synthesis of certain fats, providing some supportive effect on weight control. However, probiotics are not a miracle weight-loss solution and cannot directly alter one's inherent body constitution.
The key factors influencing weight change remain diet composition and exercise habits. Relying solely on probiotics without controlling intake of high-calorie foods or engaging in physical activity makes achieving weight loss goals very difficult.
In addition, the effects of probiotics vary from person to person, and different strains have different actions. Blind supplementation may fail to achieve the desired results. In daily life, effective weight management requires combining a balanced diet with regular exercise.
