How Does Exercise Impact Weight Loss?

How Does Exercise Impact Weight Loss?

Developed and produced by http://www.MechanismsinMedicine.com
Animation description: In this animation, we discuss the concept of physical activity and exercise as they relate to obesity.
In humans there is a fine balance between energy intake and energy expenditure.
Energy intake is in the form of food, and energy expenditure is in the form of the basal metabolic rate and physical activity.
The difference between energy intake and energy expenditure is the net energy balance. If intake exceeds expenditure, then a net positive energy balance occurs.
Energy expenditure depends on a number of factors.
This includes the starting body weight, the basal metabolic rate and physical activity.
With regards to physical activity, there are several key variables including the frequency, intensity, duration and type of activity done.
Let us now examine energy consumption. One honey glazed donut is shown which has approximately 300 kilocalories.
The energy intake from the consumed donut is equal to the energy consumed by moderate walking for 30-60 minutes, at 3.0 miles per hour.
If an individual walks for an hour at 3 miles per hour.
They will expend approximately 300 kilocalories, the same as what was contained in the consumed donut.
If an individual walks daily for one hour at approximately 3 miles per hour. This type of activity would lead to weight loss. This assumes that the individual does not consume any extra calories and has a net negative energy expenditure.
If this activity continues for a period of two to four months, body weight is reduced as depicted.
The initial weight loss is the result of a negative net energy balance.
The negative energy balance is because energy expenditure exceeds energy intake.
After the initial weight loss, the individual continues to do the same type of exercise, that is, 1 hour of moderate walking daily.
The chart depicts changes in body weight over time.
Individuals are surprised and frustrated that his weight is not continuing to decrease despite regular walking.
They have reached a plateau.
The reason behind the weight loss pleateau is that with decreased body weight, the basal metabolic rate also decreases.
When the basal metabolic rate decreases, there is a decrease in total energy expenditure.
If the discouraged individual quits his daily walking exercise. The weight is gained again, at a quicker pace.
The weight is re-gained as a result of a positive energy balance being created.
Energy expenditure is now less since the physical activity has been stopped.
By keeping the same intensity and duration of walking without making any changes in the diet (energy intake) the man would enter a weight maintenance phase.
This is characterised by gaining a small amount of weight.
The weight maintenance is the result of an energy balance being established within the body, where energy intake essentially equals energy expenditure.
If there is no change in energy balance, there will not be any further change in weight.
What must be done to end the weight loss plateau?
Several options exist to maintain a negative net energy balance. These involve either decreasing energy intake or increasing energy expenditure.
Options include: restricting calories further or increasing the frequency, or the intensity or the duration of the exercise.
In summary then, weight loss plateau’s are expected and can only end with continued exercise and a net negative energy balance.
Stopping exercise or increasing calories will lead to weight gain.
If one continues to exercise to maintain a net negative energy balance weight loss will be promoted.

    The easiest way to burn fat and lose weight is not exercising. Exercising is pretty hard and is not the number one most effective way to burn fat. The most effective way to burn fat is with the metabolism. Metabolism is the complex process when calories from your food and beverages are combined with oxygen to create the energy your body and system needs to work.

    Burn more calories than intake. Than Pletau can’t affect you.

    πŸ˜ŠπŸ’‹πŸ˜ 😘
    If you want to lose weight, you need to reduce carbohydrates and increase fat. That’ll lose more than 33 pounds in two months.

    This is a scientific fact.

    No such things as energy balance, your body DO NOT calculate calories thats why all diets based on this theory are failing in long term



  17. Nestor Liberty on June 20, 2021 at 12:32 am

    Can someone please explain in simpler terms why you’ll gain weight back (and faster) if you stop exercising, but don’t consume more calories than your body needs?

  40. patricia muli on June 20, 2021 at 12:52 am

    that donut has a lot of power πŸ™Œ



  41. Challis Finn on June 20, 2021 at 12:53 am

    Exercising for weight loss is important but controlling what we eat it is equally important, for example:

    -Choose low-fat and low-calorie foods.
    -Eat smaller portions.
    -Drink water instead of sugary drinks.
    -Be physically active.

    I would highly recommend an Ebook recently released by Pelette that is totally free. And its only interest is to provide good information for your health and avoid excess weight.

    For all who keep saying β€œI wish I looked like..” stop saying that. Don’t compare yourself to others. Say β€œ i am going to look like…”. Stop wishing. Get up and start your journey. I’ve been wishing for almost 2 years and now I am going to start my journey. I can do it and you can too. Don’t give up.



  44. Bill J.Kamealoha on June 20, 2021 at 1:02 am
