Obesity and chronic disorders connected to nutrition are on the rise in countries going through nutrition transition. In transitional nations, children's micronutrient deficiencies (zinc, iron, and vitamin A) and stunting (short stature relative to age) combine with obesity and non-rheumatic chronic diseases (NRCDs), creating a double burden of nutritional illness. Obesity and non-restricted childhood diseases (NRCDs) have a complex and multifaceted causation web; dietary and physical activity changes in the population are probably the key concurrent determining factors. Recent research, however, points to certain patterns of fetal and postnatal growth as possible additional factors. Research suggests that rather than focusing on weight gain, intervention measures to avoid malnutrition should prioritize gains in linear growth during the first two to three years of life. It is essential to prevent excessive weight increase in height gain (BMI) after the first two years of life. To prevent obesity and non-communicable diseases (NRCDs) early in life, it is essential to regularly assess children's growth using the new World Health Organization (WHO) standard, to define energy needs using the most recent Food and Agricultural Organization (FAO)/WHO norms, and to provide essential micronutrients to support lean mass growth. By preventing and controlling juvenile obesity, these measures should help avoid NRCDs in upcoming adult generations.
