Family-based time-restricted eating and lifestyle changes improved weight and metabolic health in four obese adolescents over one year.

The global burden of childhood and adolescent obesity continues to rise sharply. According to the 2024 NCD Risk Factor Collaboration Report, over 390 million individuals aged 5–19 years were overweight in 2022, with obesity increasing more than fourfold since 1990. In India, adolescents account for nearly one-fifth of the population, with approximately 6% overweight and 2% obese, signaling an urgent public health challenge.
A recent clinical case series offers an instructive real-world perspective. Four adolescents from a single joint family, including a 17-year-old proband with prediabetes (HbA1c 6.2%), presented with elevated BMI (>+2 SD), insulin resistance (raised TyG index), dyslipidemia, and early liver enzyme abnormalities. Shared dietary patterns, long eating windows (16–17 hours), and low physical activity were key contributors.

Instead of pharmacological or surgical options, a structured family-centered intervention was implemented. This included gradual time-restricted eating (progressively reduced to 12 hours), substitution of high-calorie foods with lower-calorie alternatives, increased protein-rich foods, and stepwise increases in physical activity.

After 12 months, all four adolescents showed meaningful improvements in BMI, waist circumference, fasting glucose, lipid profile, and liver enzymes. The proband’s glycaemic status normalized, while no nutritional deficiencies were observed.

This case series underscores a critical message: early, sustained, and family-engaged lifestyle modification can meaningfully alter the trajectory of adolescent obesity and its metabolic complications.
