Metabolic syndrome is a cluster of disorders diagnosed simultaneously in an individual. The percentage of individuals affected from this syndrome is escalating around the globe as well as in Pakistan mainly due to more consumption of energy dense foods and sedentary lifestyle. Dietary modification with nutrient dense foods is a globally adapted strategy to reduce the complexity of this issue. This present project has been designed to see the impact of nutrient dense walnuts consumption on selective biomarkers in human subjects. The screening of human subjects was done by taking the anthropometric measurements, lipid profile, blood glucose level and blood pressure whereas the dietary pattern of patients was collected by validated food frequency questionnaire. The proximate analysis of walnuts was also done. Twenty patients were selected and divided into two groups randomly. Experimental group consumed walnuts daily for 8 weeks and placebo group consumed the diet without walnut. Selective physical parameters included BMI was performed at the regular basis whereas, the blood samples were collected at 1st , 4th  and  8th week of the study period followed by the evaluation of serum triglyceride and high density lipoprotein cholesterol level. Walnuts were found to be high in fat content i.e 64.6% and also contained all other important nutrients as moisture (3.9%), ash (1.5%), protein (15.3%), fiber (1.5%) and nitrogen free extract (10.7%). Walnuts reduced triglycerides significantly and HDL was also raised significantly. No significant change was observed in BMI. Statistical analysis was employed to draw the conclusive outcomes of the research studies.
