Hello, this is Director Oh Jung-min of Doctor O Clinic.

I recently appeared on TV Chosun’s Master’s Guide episode, “The Fear of Gut Toxins,”

and had an in-depth discussion about the relationship between gut health and obesity, as well as the diet probiotic BNR17.

Based on the broadcast content, I will briefly summarize the “fundamental cause of weight gain” that many people are curious about~

Q. Why can’t I lose weight no matter how hard I try?

Do you work hard on dieting, only to regain the weight quickly, or do you worry that your body type makes it easier for you to gain weight than others?

The answer lies in our “gut microbiota.”

When harmful bacteria increase in the intestines, the body develops “obesity memory,” in which it recognizes an obese state as normal.

Because of this memory, the body keeps trying to return to its former obese state even after dieting,

and this is what we call the yo-yo effect.

In the mouse experiment introduced on the program, when harmful bacteria were introduced, the mice gained weight,

and when beneficial bacteria were increased again to eliminate the harmful bacteria, the mice lost weight.

What helps erase this “obesity memory” and improve the intestinal environment is

Lactobacillus gasseri BNR17.

Research on the effects of Lactobacillus gasseri BNR17 - In a double-blind, randomized, controlled trial conducted at Seoul National University Hospital and Yeungnam University Hospital,

62 overweight and obese adults were

given Lactobacillus gasseri BNR17 daily for 12 weeks,

and reductions in waist circumference, body weight, and BMI were observed.

BNR17 does not simply help with bowel movements to promote weight loss;

it also inhibits the absorption of monosaccharides

and activates fat-burning genes to help burn body fat.

In addition, it improves resistance to leptin, the hormone that makes us feel full,

and works by increasing insulin sensitivity and reducing unnecessary false hunger,

thereby helping with weight loss.

Many probiotics talk about gut health,

but BNR17 is a strain whose body fat reduction mechanism has been scientifically proven through SCI-level papers,

and the key is not simply starving yourself to diet, but changing the “gut ecosystem”

so that you become a body type that does not gain weight easily.

Rather than dieting to reduce visible numbers,

it is important to restore and correct the balance of the intestinal environment.

When the gut is healthy, the skin barrier also becomes stronger,

because only then can natural beauty be completed.

Start a healthy diet together with me, Director Oh, at Doctor O Clinic.

Thank you.
