Question

1. reflect: o how could gaining or losing muscle affect your bmr? o why can’t exercise alone make up for an unhealthy diet? o which macronutrient (carb, fat, or protein) requires the most energy to digest? o how do your results compare to your current eating habits or activity level?

Explanation:

1. Muscle is more metabolically - active than fat. Gaining muscle increases BMR as muscles require more energy at rest. Losing muscle decreases BMR.
2. Exercise burns calories, but an unhealthy diet may lack essential nutrients, contain excessive amounts of harmful substances like saturated fats and added sugars, and exercise alone cannot correct these nutritional imbalances.
3. Protein requires the most energy to digest. This is known as the thermic effect of food, and protein has a higher thermic effect compared to carbs and fats.
4. Without specific results provided, one would compare personal data (e.g., calorie intake, macronutrient ratios) from a diet or activity assessment to their current eating and activity patterns to identify areas for improvement or confirmation of healthy habits.

Answer:

1. Gaining muscle increases BMR; losing muscle decreases BMR.
2. Exercise can't correct nutritional imbalances in an unhealthy diet.
3. Protein requires the most energy to digest.
4. Comparison depends on personal results from diet/activity assessment.
