Calories – Inside Out

We all know that there is a close link between body weight and heart health. In fact, obesity or excessive body weight in relation to height, is an independent risk factor for cardiovascular disease.

Regular exercise along with a healthy diet can help maintain physical, physiological and mental health. Many of us want to reduce weight; some of us wish to gain weight. An important thing to understand before making any weight management plan is the concept of calorie intake and calorie expenditure.

Calorie intake per day refers to the amount of calories that is being taken in the form of foods or supplements by an individual in a 24-hour period. Calorie expenditure refers to the amount of calories that is being burned out by an individual in the same time period. The overall working of our body relies on these two things, in short, on our body metabolism.

Now let us see what Positive calorie intake and Negative calorie intake are. Positive calorie intake refers to calorie intake being higher than calorie expenditure and negative refers to intake being lesser than expenditure.

Positive calorie intake = calorie intake > calorie expenditure = Weight Gain

Negative calorie intake = calorie intake < calorie expenditure = Weight Loss

In India, an average working individual consumes around 2100 – 2500 kcal in a normal day (weekday) and goes upto 3000 kcal during the weekends (outside food consumption). Our body at a resting state expends around 1200 – 1400 kcal for carrying out our basic functioning. Overall an individual has around 600 to 700 calories being left unused post consumption. This results in calorie overload, leading to weight gain.

Incorporation of physical activity and exercises can help in depleting the additional calories. Moreover, a minimal modification in the calorie intake with the help of a dietitian can help you shift from a positive calorie intake to a negative calorie intake resulting in weight loss.

Use of indoor equipments like treadmill, cycle ergometer, and cross trainer with adequate speed, inclination and resistance, burns around 300 – 400 kcal/hr. Outdoor activities such as jogging, swimming, brisk walking, hiking and cycling burns up-to 400 – 500 kcal/hr. Individuals involved in sports such as badminton, tennis, cricket, basketball, volleyball, football etc expend about 450 – 600 kcal/hr. Other activities like Zumba, Pilates, Yoga and Gymnasium can also help you loose your extra calories and attain an ideal body weight. If you are underweight and are planning to gain weight, it should be a healthy weight gain resulting from the intake of a healthy balanced diet and engaging in appropriate exercises rather than taking nutritional supplements, eating junk food and performing excessive exercises and succumbing to injuries.

Some important points to keep in mind with calories…

  1. 3,500 kcal = 0.45 kg of fat
  2. Adequate calorie expenditure = 200 – 400 kcal/day (or) 1000 – 1500 kcal/week
  3. Exercise 3-5 days/week for aerobic training, 2-3 days/week for resistance training and daily 15-20 minutes/day for abs and core training for more calorie expenditure
  4. Healthy weight loss = 1-2 kg/month
  5. Adequate calorie intake for weight loss =1600 – 1800 kcal/day
  6. Spend more time in outdoor activities and sports that you enjoy; it will help relieve your stress and expend those extra calories
  7. Incorporate a combination of workouts (rather than the same routine everyday) for better calorie expenditure
  8. High intensity interval training and resistance training burns calories even after the workout session.

Regular exercise and a good diet are sure to help you reach your health goals. Additionally, having an idea of your calorie intake and expenditure is important to maintain fitness and body weight. This is especially true for those of us who are diabetic, hypertensive, obese and diagnosed with heart problems. Better weight management is a sure-shot strategy to improved health metrics. Eat right, stay fit and always believe that you can!
