The aim of this randomized group experimental study was to investigate the effects of a sattvic diet and hatha yogic practices on a few selected parameters in middle-aged women with hypothyroidism. It was predicted that middle-aged obese women who practiced hatha yoga would differ significantly from the control group in terms of their BMI and thyroid stimulating hormone. Thirty middle-aged women, ranging in age from 35 to 60, were chosen at random from Vijayawada for the study. They were split into two groups, A and B, each with fifteen subjects. Prior to the commencement of the training program, a pretest on the chosen dependent variables was administered to Groups A and B. Group B (Control Group) did not receive any specific treatment, but instead engaged in active rest. Group A was given hatha yogic practices along with a modification of their sattvic diet. The Group A and B were retested on the same chosen dependent variables as the posttest following the 12-week experimental period. The effectiveness of the experimental and the control group was analyzed using paired t test and independent t test. The significance test had a fixed confidence level of 0.05. The study findings on the thyroid stimulating hormone and chosen body mass index find that the Experimental Group's yogic practices and sattvic diet modifications caused them to differ significantly from the Control Group. The hypothesis was accepted with a confidence level of 0.05. Therefore, middle-aged hypothyroidism women's body mass index and thyroid stimulating hormone were reduced by yogic practices combined with sattvic diet modifications.
