Why weight gain isn’t always about food: 4 factors to consider

Weight gain can occur for reasons beyond simply consuming too many calories, as nutritionist Sonia Narang recently explained on entrepreneur Prashant Desai's podcast. While food is the most obvious factor, other lifestyle elements such as hydration, sleep, and physical activity also play crucial roles.

According to Head of Dietetics at PSRI Hospital, Shalini Bliss, these four pillars work together to regulate body weight and metabolism, rather than acting independently. Food is the most apparent factor, with excess calories from calorie-dense processed foods contributing to body fat. However, weight management should not only focus on eating less.

Hydration is essential, as dehydration can sometimes be confused with hunger, affecting energy levels and physical activity. Adequate water intake supports normal bodily functions and may help prevent unnecessary snacking. Sleep is another overlooked factor, as poor or insufficient sleep can disrupt hunger and satiety hormones, increase cravings, and reduce motivation or ability to exercise.

Physical activity is not solely about structured workouts; daily movement matters. Even if someone exercises regularly, prolonged periods of sitting can lower total energy expenditure. Thus, everyday movement like walking or standing is relevant to overall activity levels.

If a person is gaining weight despite eating well and maintaining a structured exercise routine, Bliss suggests looking beyond food and exercise. Factors such as sleep quality and duration, stress levels, hydration, daily movement, and portion sizes should be assessed. In some cases, underlying medical or physiological conditions like thyroid problems, certain medications, hormonal changes, or metabolic conditions can contribute to weight gain.

Therefore, it is essential to consult a doctor for persistent or unexplained weight gain. Ultimately, weight management is a multifaceted process that requires balance between nutrition, movement, recovery, and lifestyle.
