ABSTRACT
Background: Worldwide, obesity has nearly tripled since 1975 and has become a major healthcare challenge today. Intermittent fasting (IF) is gaining popularity as a weight loss strategy in recent times. This study aimed to study the role of IF as a modern-day weight-loss strategy in obese adults through a real-world pilot experiment conducted at a nutrition clinic in Mumbai. Methodology: To understand the effects of IF on weight loss, 32 overweight/obese [body mass index (BMI) ?23 kg/m2] adults from a nutrition clinic in Mumbai, were assigned consecutively to an IF plan and followed up for 3 months. Their demographic, anthropometric, and dietary assessments were done pre- and post-intervention. Qualitative interviews were done at the end of the study to record the participants’ overall well-being, experience, and sustainability of IF. Results: 56% of study participants were males and their mean age was 35.6 ± 8.9 years. 65.6% of participants were able to maintain 14–16 hours of fasting and 53% managed all 7 days of IF. Analysis of post-intervention data showed a significant reduction in mean body weight (88.5 ± 19 to 83.8 ± 17.6 kg), waist circumference (M: 108.2 ± 11.3 to 103.6 ± 4.4 cm, F: 98.9 ± 8.8 to 93.3 ± 3.3 cm), BMI (31.4 ± 5.3 to 29.6 ± 5.1 kg/m2), daily calories (1782 ± 237 to 1388 ± 243 kcal/day), carbohydrate intake (267 ± 18.4 to 164 ± 4.0 g/day), and an increase in protein intake (39 ± 11 to 55 ± 11 g/day). Participants reported positive experiences of practicing IF such as improved fitness, sleep cycle, and adoption of healthy eating habits. Conclusion: The study demonstrates that IF could aid in weight loss and adoption of a healthier lifestyle.
ABSTRACT
Background & objectives: Childhood obesity is a known precursor to obesity and other non-communicable diseases (NCDs) in adulthood. However, the magnitude of the problem among children and adolescents in India is unclear due to paucity of well-conducted nationwide studies and lack of uniformity in the cut-points used to define childhood overweight and obesity. Hence an attempt was made to review the data on trends in childhood overweight and obesity reported from India during 1981 to 2013. Methods: Literature search was done in various scientific public domains from the last three decades using key words such as childhood and adolescent obesity, overweight, prevalence, trends, etc. Additional studies were also identified through cross-references and websites of official agencies. Results: Prevalence data from 52 studies conducted in 16 of the 28 States in India were included in analysis. The median value for the combined prevalence of childhood and adolescent obesity showed that it was higher in north, compared to south India. The pooled data after 2010 estimated a combined prevalence of 19.3 per cent of childhood overweight and obesity which was a significant increase from the earlier prevalence of 16.3 per cent reported in 2001-2005. Interpretation & conclusions: Our review shows that overweight and obesity rates in children and adolescents are increasing not just among the higher socio-economic groups but also in the lower income groups where underweight still remains a major concern.
