Let's carefully analyze Samia's caloric balance to determine the likely outcome if she continues her current pattern for multiple weeks.
1. Basal Metabolic Rate (BMR):
- This is the number of calories her body burns just to maintain basic physiological functions while at rest.
- Samia’s BMR is 1,680 calories per day.
2. Calories Consumed:
- These are the calories she intakes through food and beverages.
- On the first day, she consumed 1,940 calories.
3. Calories Burned:
- These are the additional calories she burns through physical activities such as exercises.
- On the first day, she burned 280 calories from a six-mile bike ride.
4. Net Calories Input (Calories Consumed):
- This is simply the amount of calories she took in.
- [tex]\( \text{Net Calories In} = 1,940 \)[/tex] calories.
5. Net Calories Output:
- This is the sum of her BMR and the calories she burned through physical activity.
- [tex]\( \text{Net Calories Out} = \text{BMR} + \text{Calories Burned} = 1680 + 280 = 1,960 \)[/tex] calories.
6. Caloric Balance:
- This is the difference between the net calories consumed and the net calories burned.
- [tex]\( \text{Caloric Balance} = \text{Net Calories In} - \text{Net Calories Out} = 1,940 - 1,960 = -20 \)[/tex] calories.
From this analysis, the caloric balance is -20 calories. This means Samia is burning 20 more calories than she is consuming each day.
If Samia continues this pattern for multiple weeks, she will be in a consistent calorie deficit. Over time, this consistent deficit will likely lead to weight loss. Therefore, the most appropriate outcome, if Samia maintains this pattern, would be:
She will lose significant weight.
