The purpose was to compare the effects of diet and exercise and laser interference and maneuver on anthropometric parameters and blood effects of object agents. The study was a randomized controlled longitudinal study. It included 45 adolescents from both sexes who were divided randomly into two groups: one group was treated with low calorie diet and exercise as group A and group B was treated with low calorie diet, exercise, and laser acupuncture. All parameters and blood samples were done before and after the interventions. Group A showed a highly significant reduction post intervention in anthropometric parameters: triceps skin fold thickness (SFT), biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, mid-upper arm circumference (MUAC), waist C, and hip C, except for waste/hip (W/H) ratio which showed no significant difference,p > 0.05 and some lipid profiles (cholesterol, LDL) with p < 0.001 Whereas, a significant decrease in TG was observed (p < 0.05). On the other hand, a significant increase in HDL was observed (p < 0.05). Group B (LCD + exercise + LA) showed a highly significant reduction post intervention in anthropometric parameters: triceps SFT, biceps SFT, subscapular SFT, suprailiac SFT, abdominal SFT, MUAC, waist C, and Hip C, except for W/H ratio which showed no significant difference,p > 0.05 and lipid profile: cholesterol, LDL, and TG with (p < 0.001), whereas a highly significant increase in HDL was observed (p < 0.001). The current study revealed a significant difference between group A and group B regarding the percentage of change, where the highest values were found in group B compared to group A, in anthropometric parameters (weight, BMI, subscapular SFT, MUAC, waist circumference) and some lipid profiles (LDL and HDL) with p < 0.05. Laser acupuncture was a safe, easy, and more effective tool with extra effect in management of obesity when added to diet and exercise on anthropometric parameters and lipid profile.
