Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_train_226 ( "id" int, "gender" string, "pregnancy_or_lactation" bool, "active_metabolic" bool, "diabetic" string, "hepatic_disease" bool, "gastrointestinal_disease" bool, "body_mass_index_bmi" float, "age" float, "NOUSE" float )

### Question ###
bmi greater than or equal to 18.5 kg / m2 and less than 40 kg / m2

### Accurate SQL ###

SELECT * FROM table_train_226 WHERE body_mass_index_bmi >= 18.5 AND body_mass_index_bmi < 40
