Having grown up in a home where he did not exercise and ate lots of snacks, Nicholai has spent many years overweight. He does not like the way he looks and feels, so he decides to go on an extreme diet where he only eats one can of tuna per day and exercises for three hours every morning. Explain the principles of energy balance to Nicholai. How did they apply to his former lifestyle and how do they apply with his current diet plan? How might Nicholai make changes in a balanced way?

Answers 2

The principle of energy balance The principle of energy balance underpins the thermodynamic principle that energy cannot be destroyed but can only be:

  • Obtained
  • Lost or
  • Stored by an organism.

The three essential components of energy balance are:

  • Energy intake
  • Energy dissipation
  • Energy storage

The body weight of a human body may change over time if the energy intake is not equal to the energy dissipation.

This applies to the former life Nicholai was living because Nicholai ate too many snacks without exercising.

  • In this case, the energy intake is higher than the energy dissipation which leads to an increase in Nicholai body overweight.

Now, since Nicholai is determined to change his former body status by performing the exercise:

  • Nicholai must adhere to eating one can of tuna per day and exercising for three hours every morning as this will help him in a balanced way of maintaining an equal amount of energy intake and energy dissipation.

Quick Answer: Energy balance is the principle of balancing the energy you take in with the energy you expend. Nicholai was likely in an energy surplus before, taking in more calories than he expended, but his current diet and exercise plan will result in an energy deficit, meaning he will be taking in less calories than he expends. To make changes in a balanced way, Nicholai should focus on eating whole, nutritious foods and incorporating exercise into his daily routine but in a manageable and sustainable way. Full Explanation: The principle of energy balance states that the energy you take in (through food) should be equal to the amount of energy you expend (through physical activity). If they are not equal, it affects your body's energy reserves. For example, if you consistently take in more calories than you expend (called an energy surplus), you will gain weight as your body stores the excess energy as fat. On the contrary, if you constantly expend more energy than you take in (called an energy deficit), your body will use your stored fat as energy, causing you to lose weight. Nicholai's former lifestyle is likely an example of an energy surplus as he was likely eating more snacks and not expending much energy through physical activity. His current diet plan of only eating one can of tuna per day and exercising three hours every morning is an example of an energy deficit, meaning he is taking in fewer calories than he is expending. To make changes in a balanced way, Nicholai should focus on eating whole, nutritious foods and incorporating exercise into his daily routine. He should also strive to create an energy balance by not over-restricting his calorie intake and making sure he is expending enough energy through exercise. This way, he can make changes in a sustainable and manageable way.
