Synopsis: Experts said that weight changes are often influenced by deeper lifestyle factors such as sleep quality and stress levels. When these are ignored, even sincere efforts toward weight loss may not produce the expected results.
Most people who are trying to manage their weight focus mainly on diet plans and exercise routines. However, experts said that weight changes are often influenced by deeper lifestyle factors such as sleep quality and stress levels.
When these are ignored, even sincere efforts toward weight loss may not produce the expected results.
Dr S Jayaraman, Senior Consultant in Pulmonary Medicine at MGM Healthcare in Chennai, explained to South First that sleep, stress, and weight are closely connected.
Chronic stress triggers the release of hormones such as cortisol and adrenaline, which can disturb sleep patterns and metabolic functions. This imbalance may either cause unexpected weight gain or weight loss, depending on how the body responds.
According to him, sleep disorders such as insomnia and obstructive sleep apnea are commonly linked with metabolic issues like diabetes, hypertension, and obesity.
Poor sleep can disrupt insulin function, influence hunger hormones, and encourage unhealthy eating patterns, all of which make weight management difficult.
Modern work schedules and lifestyle habits often disrupt natural sleep cycles and increase stress, Dr Jayaraman noted, adding that irregular sleep timing, late dinners, and insufficient rest can alter hormonal balance and slow metabolic activity.
These factors can also increase the risk of sleep apnea, a condition marked by repeated breathing interruptions during sleep, often signalled by habitual snoring.
Daytime fatigue, excessive sleepiness, and difficulty concentrating may also indicate underlying sleep or metabolic problems, he said.
Dr Jayarama sadi sudden weight changes, whether gain or loss, should not be ignored as they could signal medical conditions such as uncontrolled diabetes or other systemic illnesses.
Dr Jayaraman emphasised the importance of consistent and sustainable habits instead of quick fixes:
• Maintaining balanced nutrition: Consuming a well-rounded diet that includes proteins, carbohydrates, fats, vitamins, and minerals supports metabolic stability and prevents unhealthy weight fluctuations.
• Following a regular exercise routine: Engaging in physical activity for at least 45 minutes to one hour daily, such as brisk walking, cycling, or sports, helps regulate metabolism and improve overall health.
• Prioritising quality sleep: Getting around seven to eight hours of uninterrupted night sleep is essential for hormonal balance and metabolic regulation.
• Adopting a fixed sleep schedule: Going to bed and waking up at consistent times helps maintain the body’s internal clock and improves sleep quality.
• Eating dinner early and light: Consuming easily digestible food at least two to three hours before bedtime supports better digestion and restful sleep.
Dr Jayaraman added that recognising warning signs such as persistent snoring, daytime exhaustion, or unexplained weight changes should prompt medical consultation, as early diagnosis can prevent long-term health complications.
