PLEASE HELP! 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?
