Weight gain is something most of us have experienced at some point, but when excessive fat accumulation becomes a chronic, systemic condition, it crosses into obesity territory. And in India, that line is being crossed more often than ever.
Obesity has, for the first time, surpassed underweight as the most common form of malnutrition among school-age children and adolescents globally. In adults, obesity among Indian women rose by 91% in under two decades.
This article covers what obesity actually means, why it happens, the serious health risks it carries, and how yoga offers a proven, accessible path toward weight management.
What is Obesity?
Obesity is a chronic medical condition characterised by excessive accumulation of body fat to a degree that impairs health. It is not simply a matter of appearance or willpower. It involves complex interactions between genetics, hormones, environment, and behaviour.
The most widely used measurement tool is BMI (Body Mass Index), calculated by dividing weight in kilograms by height in metres squared (kg/m²).
For Asian Indians specifically, the Indian Council of Medical Research (ICMR) uses a BMI of 25 kg/m² or above as the threshold for obesity, which is lower than international standards because Indian bodies tend to accumulate harmful visceral (abdominal) fat at lower BMI levels.
WHO Classification of BMI:
| BMI | Classification |
| Below 18.5 | Underweight |
| 18.5 to 24.9 | Normal weight |
| 25.0 to 29.9 | Overweight (Grade 1) |
| 30.0 to 39.9 | Obese (Grade 2) |
| Above 40 | Morbidly Obese (Grade 3) |
There is also a clinically important concept called metabolic obesity in normal weight (MONO): individuals who appear slim by BMI but carry dangerous levels of visceral fat and metabolic risk factors. The ICMR-INDIAB study found that 43.3% of Indian adults fall into this MONO category, making it the most common obesity subtype in the country.
What Are the Symptoms of Obesity?
Obesity rarely presents with a single obvious sign. It tends to develop gradually and shows up across multiple systems:
- Excessive weight gain and visibly increased body fat, particularly around the abdomen, hips, and thighs
- Breathlessness with minimal physical activity
- Increased sweating and body odour
- Persistent fatigue and low energy
- Joint pain, especially in the knees, hips, and lower back, caused by excess load on the musculoskeletal system
- Snoring or sleep apnoea (interrupted breathing during sleep)
- Irregular menstrual cycles in women
- Low confidence and mood-related changes, including anxiety and depression
- Skin changes such as stretch marks, darkening around the neck or underarms (acanthosis nigricans), and increased susceptibility to fungal infections in skin folds
General Causes of Obesity
At its core, obesity results from an energy imbalance, meaning more calories consumed than expended over time. However, there are multiple reasons behind that imbalance:
- Sedentary lifestyle: Long working hours, desk jobs, increased screen time, and reduced physical activity are all significant contributors. Physical inactivity is among the most consistent risk factors identified in the ICMR-INDIAB national study.
- Ultra-processed foods (UPFs): Packaged snacks, fried foods, sugary beverages, and instant meals are calorie-dense but nutritionally poor.
- Genetics: A family history of obesity increases the likelihood of developing it. Certain genes affect how the body stores fat and regulates appetite hormones like leptin and ghrelin.
- Hormonal imbalances: Conditions like hypothyroidism, PCOS, Cushing’s syndrome, and insulin resistance can all drive weight gain independently of diet.
- Chronic stress and poor sleep: Elevated cortisol from chronic stress promotes fat storage, particularly in the abdominal area. Poor sleep disrupts hunger-regulating hormones, increasing cravings for high-calorie foods.
- Certain medications: Antidepressants, antipsychotics, corticosteroids, and some diabetes medications can contribute to weight gain as a side effect.
- Gut microbiome imbalances: Emerging research suggests that the composition of gut bacteria influences how efficiently calories are extracted from food and stored.
Health Risks Associated With Obesity
Obesity is a gateway to several serious, potentially life-threatening conditions:
- Type 2 diabetes: Metabolically obese individuals carry up to 12.89 times the risk of developing type 2 diabetes compared to metabolically healthy, normal-weight individuals, according to the ICMR-INDIAB study.
- Cardiovascular disease: Excess body fat raises blood pressure, LDL (bad) cholesterol, and triglycerides, all of which strain the heart and arteries.
- Chronic kidney disease (CKD): Metabolic obesity significantly elevates CKD risk, particularly among Indian women.
- Fatty liver disease (NAFLD): Excess fat deposits in the liver impair its function over time.
- Sleep apnoea: Extra weight around the neck can obstruct breathing during sleep, causing repeated waking and oxygen deprivation.
- Joint disorders: Osteoarthritis, particularly in the knees and hips, is significantly worsened by carrying excess weight.
- Certain cancers: As observed by Mayo Clinic, obesity is linked to increased risk of breast, colon, endometrial, kidney, and oesophageal cancers.
- Mental health impact: Depression, anxiety, low self-esteem, and social withdrawal are common and frequently underacknowledged consequences of obesity.
Obesity in Teens and Children
This is where the numbers become especially sobering for India. NFHS data shows that overweight and obesity in adolescent girls increased by 125% and in adolescent boys by a striking 288% between 2005 and 2021. In children under five, the prevalence of overweight more than doubled in just over a decade.
India is projected to have over 27 million children and adolescents aged 5 to 19 living with obesity by 2030, accounting for 11% of the global population.
The key drivers in this age group include:
- Replacement of traditional diets with fast food, sugary drinks, and packaged snacks
- Increased screen time and reduced outdoor play
- Exposure to aggressive food advertising on digital platforms
- Academic pressure reducing time for physical activity
Once established in childhood or adolescence, obesity is significantly harder to reverse and tends to persist into adulthood, laying the groundwork for lifelong metabolic disease. Early family-led lifestyle changes (diet, activity, sleep) are the most effective form of intervention.
Can Yoga Help to Reduce Weight and Obesity?
Yes, and the evidence supports it. A study published in the International Journal of Pharmaceutical Chemistry and Analysis found that yoga therapy shows meaningful improvement in subjective symptoms of obesity and significant results in weight and BMI reduction. Yoga works as a weight management tool through several interconnected pathways:
- Lowering cortisol: Elevated stress hormones promote fat storage. Yoga reduces cortisol, which in turn supports healthier body composition.
- Improving insulin sensitivity: Regular practice helps the body respond to insulin more effectively, reducing the risk of metabolic obesity.
- Stimulating metabolism: Certain asanas activate the endocrine glands (thyroid, adrenal), which regulate how quickly the body burns energy.
- Improving digestion: Twisting and forward-folding poses massage the internal organs, promoting better gut function and nutrient absorption.
- Supporting mindful eating: Yoga builds body awareness, which reduces emotional eating and unconscious overconsumption.
- Enabling more movement: By reducing joint pain and improving flexibility, yoga makes it physically easier to be active throughout the day.
We believe that yoga combines movement, breathing, and mindfulness, making it effective not just for shedding weight but for achieving overall wellness.
Yoga Poses for Weight Loss and Obesity
These asanas are particularly effective for weight management and fat loss across the body:
Surya Namaskara (Sun Salutation)
A flowing 12-step sequence that targets the arms, shoulders, core, back, and legs in one continuous movement. It elevates the heart rate, improves cardiovascular health, and stimulates metabolic function. Aim for 5 to 10 rounds daily for best results.
Trikonasana (Triangle Pose)
Stand with legs wide apart, extend one arm down toward the ankle and the other upward. Engages the legs, core, and obliques. Helps regulate cortisol and stabilise blood glucose levels, making it especially useful for those with metabolic obesity or PCOS-related weight gain.
Utkatasana (Chair Pose)
Stand with feet together, bend the knees as if sitting in a chair, and extend the arms overhead. Activates the quadriceps, glutes, hamstrings, and core simultaneously. Promotes healthy digestion and raises the metabolic rate.
Dhanurasana (Bow Pose)
Lie face-down, bend the knees, reach back to hold the ankles, and lift the chest and thighs off the floor. Reduces abdominal fat, stimulates digestion, and improves metabolic function. Particularly effective for toning the abdominal region.
Phalakasana (Plank Pose)
Hold a push-up position with arms straight, core engaged, and body in a straight line from head to heels. Builds core strength, increases endurance, and burns calories by engaging multiple large muscle groups simultaneously.
Paschimottanasana (Seated Forward Fold)
Sit with legs extended, reach forward toward the feet, and hold. Strengthens abdominal muscles, shapes the abdomen, and reduces sciatica-related discomfort. Also promotes mindfulness and stress relief.
Setu Bandha Sarvangasana (Bridge Pose)
Lie on your back, knees bent, feet flat on the floor. Lift the hips while keeping the shoulders grounded. Strengthens the glutes, hamstrings, and back, improves circulation, and supports better sleep quality, which is closely linked to healthy weight.
Pavanamuktasana (Wind-Relieving Pose)
Lie on your back and pull both knees toward the chest. This pose massages the abdominal organs, improves digestion, and reduces fat accumulation in the lower abdomen.
Practice yoga consistently, four to five times a week, for at least 30 to 45 minutes per session. Begin on an empty stomach, ideally in the morning. If you have existing joint issues, injuries, or chronic health conditions, consult a doctor or certified yoga instructor before starting.
Final Thoughts
Obesity in India is rising across every age group, and the risk it carries goes well beyond weight on a scale. It touches metabolic health, heart health, joint health, mental wellbeing, and reproductive health.
The encouraging truth is that it is a condition that responds to consistent, sustainable action. Diet, movement, sleep, and stress management all play a role, and yoga is a uniquely practical addition to that mix.
It costs nothing, requires no equipment, and meets you exactly where you are. If you suspect obesity or a related metabolic condition, speaking with your doctor early gives you the clearest path forward.
