Can yoga help reduce weight?
According to various scientific studies published over time, it is evident that yoga helps reduce body weight. A couple of studies are given below as a reference.
A study published in the International Journal of Research in Medical Sciences (See Ref.No:5 below) observes that statistically significant decrease in Systolic BP, Diastolic BP, and BMI after 3 months of Yoga training.
A study (See Ref.No:6 below) published in Medical Science Monitor on 21.12.2009, ID: 878317 observes that following the 6-day yoga residential program, participants showed a decrease in BMI (1.6 percent), waist and hip circumferences, fat-free mass, total cholesterol (7.7 percent decrease), high-density lipoprotein (HDL) cholesterol (8.7 percent decrease), fasting serum leptin levels (44.2 percent decrease) and an increase in postural stability and handgrip strength (p<0.05, all comparisons).
A study (See Ref.No:7 below) published in Clinical Nutrition in 2006 observes that the objective of this study was to evaluate the effects of Hatha and relaxation yoga on obesity, blood pressure, and quality of life. Seventy healthy women and men aged 18 years or older completed a survey. A statistically significant body mass index for obesity (30.0) was observed (P < .001). A significantly lower systolic blood pressure was detected in the 1- to 4-year yoga participant group as compared to the less than 1-year yoga group (P <.023). The mean Total Mood Disturbance score was −5.04, indicating the survey participants scored a positive mood state. Hatha and relaxation yoga had a statistically significant role in controlling weight, hypertension, and mood.
