The new diet plans unveiled by the Indian Council of Medical Research (ICMR) advise a calorie intake of 2,100 for men and 1,670 for women for those leading a sedentary lifestyle. Kanika Narang, deputy manager, dietetic department, Indraprastha Apollo Hospitals, says while this seems reasonable and aligned with general nutritional guidelines, it is crucial to note that caloric needs can vary significantly based on factors such as age, height, weight, activity level and individual metabolism.
While these recommendations provide a general guideline, it is always advisable to consult with a qualified healthcare professional or a registered dietitian to determine personalised caloric and nutritional requirements for optimal health and weight management.
How different are calorie needs for physically active, sedentary individuals, and for those with intense mental tasks, like children preparing for exams?
Physically active individuals require higher calorie intake to fuel muscle contractions during exercise and support recovery, with athletes and manual labourers potentially needing an additional 300-800 calories or more per day compared to sedentary individuals. Sedentary individuals generally have lower calorie needs, typically between 1,600 and 2,000 calories per day for weight maintenance, determined primarily by their basal metabolic rate. Individuals with intense mental activities, like children preparing for exams, may require a modest increase of 100-200 additional calories per day to support the energy demands of the brain during periods of intense cognitive effort.
What is an ideal calorie count for those with moderate physical activity, like an office-goer walking half an hour daily?
For a person with moderate physical activity, such as an office-going individual who walks for half an hour daily, the ideal calorie count would depend on various factors, including age, gender, height, weight, and overall body composition. But as per a general guideline based on clinical recommendations, an ideal calorie range for a moderately active individual would typically fall between 1,800 and 2,400 calories per day. This range takes into account the baseline calorie needs for sedentary activities, such as sitting at a desk for work, as well as the additional calorie requirements for moderate physical activity like walking for 30 minutes daily. The lower end of the range (1,800 calories) would be suitable for individuals with smaller body frames, lower muscle mass, or those seeking gradual weight loss. The higher end (2,400 calories) would be more appropriate for individuals with larger body frames, higher muscle mass, or those aiming to maintain their current weight. It is important to note that this calorie range is a general recommendation and may need to be adjusted based on individual factors, such as medical conditions, activity level variations, or specific fitness goals.
What about the aged?
When it comes to the elderly population, calorie needs can differ significantly from younger adults due to various physiological changes that occur with aging. As people age, their basal metabolic rate (BMR) tends to decrease due to a gradual loss of muscle mass and a slower metabolism. This reduction in BMR, coupled with generally lower physical activity levels, leads to decreased overall calorie needs in the elderly. Additionally, changes in hormones, appetite regulation, and sensory perception of taste and smell can affect food intake and calorie consumption. Clinical guidelines suggest that sedentary older adults over the age of 60-65 typically require around 1,600-2,000 calories per day for men and 1,400-1,800 calories per day for women. However, these ranges can vary based on factors such as height, weight, body composition, and the presence of any chronic conditions or age-related diseases. It is crucial for the elderly to consume nutrient-dense foods to meet their micronutrient requirements while adhering to appropriate calorie levels. Regular physical activity, even at moderate intensities, can also help maintain muscle mass and increase calorie needs.
Should protein intake be high in every case?
No, high protein intake is not necessarily recommended in every case. The appropriate amount of protein intake depends on various factors, such as age, sex, body weight, activity level, and overall health
