Results
There is a possibility of people with a BMI of less than 25 kg/m2 developing
NAFLD if their weight increases greatly and with a 4-7% bodyweight gain, a normal liver
may change to the NAFLD state. However, our data is insufficient to make a definite conclusion. so further studies are needed.

Baseline Characteristics
The participants of our study were people who visited our hospital for a Ningen
Dock-style health check-up from 2008 to 2016 and underwent abdominal ultrasonography(US) as part of it. From the US images in the Ningen Dock data, those double negative for fatty liver for at least 2 consecutive years and then double positive for at least 2 consecutive years were determined. After excluding those with over 20 g of alcohol consumption, those post-pancreaticoduodenectomy and those with hepatitis type B virus or hepatitis type C virus infection, 215 people remained for our study.
Participant flow
The participants of our study were people who visited our hospital for a Ningen
Dock-style health check-up from 2008 to 2016 and underwent abdominal ultrasonography
(US) as part of it. 
Data were excluded those with over 20 g of alcohol consumption, those
post-pancreaticoduodenectomy and those with hepatitis type B virus or hepatitis type C virus
infection.
So 14,989 people's data (Average 53.0 years, 6,523 men, 8,466 women) were obtained. 
From the US images in the Ningen Dock data, those double negative for
fatty liver for at least 2 consecutive years and then double positive for at least 2 consecutive
years were determined.
215 people remained for our study. We studied their annual changes in bodyweight
and BMI.(Average age 50.5 years, 106 men, 109 women)
In addition, 379 people's data were examined in the last nine years without fatty liver (average age 53.4 years, 90 men, 289 women).
Among them, 195 data were obtained who adjusted sex and age (average age 52.6 years old, 90 men, 105 women) with 215 people's data having fatty liver.
We compared two groups to study annual change of BMI in developing NAFLD.
