Yoga for Weight Loss With a Sore Back
Navjot, 15, is 158 cm tall and weighs 74 kg, with a BMI of about 29.6. She has mild low back pain after sitting in class for 6 hours and wants to join the school's 45-minute daily yoga session to lose weight quickly. She has no diagnosed spine problem, no injury, and no hypertension. She is very flexible and can touch her toes easily. She has read that forward bends and 'detox' twists are best for belly fat. She also wants to do sirshasana (headstand) because she saw it online. The school yoga teacher has 40 students of mixed fitness, one mat each, and a 45-minute period. Navjot gets breathless climbing three floors and has not done any sport for two years.
1. Is 45 minutes of daily yoga alone a good plan for Navjot's goal? Explain using energy balance and her back pain.
Read the worked answer
Yoga is useful for flexibility, balance, breathing and stress, but it is not a high-energy-cost activity. A 45-minute session typically burns a modest number of calories, far less than an hour of brisk walking, cycling or games. Weight loss depends on a sustained energy deficit, so yoga alone is unlikely to produce rapid loss, especially when she is otherwise inactive and breathless on stairs. Promising 'quick' loss would be misleading.
Her back pain after prolonged sitting is more likely related to weak trunk and hip muscles and poor sitting posture than to 'tight' hamstrings. She is already very flexible, so forcing deeper forward bends can increase strain rather than help. The correct judgement is to keep yoga as one part of a plan that also includes aerobic activity, simple strength work, reduced sitting time, sleep and a practical diet review. A 45-minute daily class is acceptable as a habit-building start, but it is not a weight-loss treatment by itself.
2. Design a safe 20-minute yoga sequence for her, and name two practices she should avoid for now with reasons.

Sequence: 3 minutes of seated slow breathing in sukhasana with a straight spine; cat–cow movement 8 slow rounds; tadasana 3 rounds with attention to posture; setu bandhasana (bridge) 3 holds of 10 seconds, feet grounded; a low-range bhujangasana (cobra) 3 rounds, keeping the neck long and the lower ribs on the floor; balasana for rest; savasana for 3 minutes.
Avoid deep seated forward bends such as forceful paschimottanasana, because she is already very flexible and pulling deeper can strain the lower back. Avoid sirshasana (headstand), because it loads the neck, requires trained supervision and is unsuitable for a beginner with low fitness. Also avoid fast, repeated twists and any pose that causes pain, dizziness or breathlessness.
The sequence is short enough for a school period, uses one mat, and teaches posture and trunk control. The teacher should check that she can breathe comfortably in every pose and stop if pain increases.
3. What else should be added over 8 weeks, and how should the plan progress safely?
Read the worked answer
Add 30 minutes of brisk walking or cycling on 5 days a week, progressing to 150–300 minutes per week. Add simple strength work twice a week: squats to a chair, wall push-ups, calf raises and a plank held for short intervals. Reduce continuous sitting by standing and moving for 2 minutes every 30–40 minutes. Review the family diet for portion size, sugary drinks and fried snacks, without imposing a crash diet.
Over 8 weeks: weeks 1–2 build the yoga habit and 15–20 minutes of walking; weeks 3–4 add a second strength session and longer walks; weeks 5–8 increase walking duration and add one game or aerobic session. Measure progress by breathlessness on stairs, waist measurement and energy levels, not only weight. Refer her if back pain radiates down the leg, causes numbness, or wakes her at night. The judgement is to make yoga a safe foundation, not a standalone cure.
