FOR those who got this far, no, you will not burn 400 calories in four minutes! Any sort of marketing campaign like this by any fitness professional is dubious. A calorie is a unit of energy. In food, calories are the amount of energy present in a serving of any food and drink. In exercise, it is the energy that is used up in any physical activity.
Here is a sample of some common food and how many calories are present in it:
1. One cup of rice
– 206 calories
2. One pack of crackers
– 120 calories
3. One tablespoon of oil
– 120 calories
Here is an example of some physical activities and the amount of calories that are used up during those activities (these are approximations from a 154-pound man. If you’re lighter, then you use less calories, if heavier... you get the point).
1. Running at eight kilometres per hour – 590 calories
2. Basketball (vigorous, not
just sitting on the bench)
– 440 calories
3. Weight Training (light
weight training, easy)
– 220 calories
So by doing the math, you have to be approximately 1,500 lbs to use up 400 calories in four minutes.
What then is a sensible approach to weight loss? Simple. Sleep well — so you recover each day. Eat healthy with controlled portions — starving yourself decreases your energy to exercise. Your body will also slow down its metabolic rate if you cut calories by too much. Exercise! Whether you’re looking to lose weight or not, the benefits of exercise for your well-being, disease-prevention and mental health are widespread. If you’re not looking to lose weight, exercise should still be part and parcel of living a healthy lifestyle.
Be sensible. If it’s too good to be true, it probably is. When embarking on a fitness regimen, it’s always a good practice to consult your doctor and a fitness professional (how to spot one is another article on its own).
When embarking on nutrition changes, it’s also a good idea to talk to a registered dietician. Trust the professionals.
Stay safe and healthy everyone.
