People's nutritional requirements are individualized, and what makes a workable controlled diet for overweight subjects is worthy of further study. The objective of this study was to analyze whether the Metabolic Typing*test can be a guide for diet recommendations and also to evaluate the effects on weight loss in these subjects. Thirty-three overweight recruits were treated with this program, and each had 3 h of the metabolic typing test, 1 h of dietary consultation, and 4 weeks of keeping a website journal regarding daily food intake. The body-mass index (BMI) , weight, fat mass, and waistline were measured before and after the program, and then results were compared. The results showed that regardless of gender. Metabolic Type® (autonomic-sympathetic, parasympathetic, and slow or fast oxidizer), and diet plan (groups I or II) , all showed significant weight-loss, fat-loss, and waistline reduction (p<0.05). However, it was found that the sympathetic type had more-significant improvements in BMI, weight, fat mass, and waistline than the parasympathetic type in the autonomic group (p<0.05). Group II had more-significant fat-loss than group I in the diet plan (p<0.05) . The fasting blood sugar level of the autonomic type was significantly higher than the oxidizer, and both the slow oxidizer and parasympathetic types showed slow declines in the glucose challenge. In conclusion, it is recommended that individualized diets and nutrients as determined by the Metabolic Typing® test can be used to efficiently carry out weight management.
