Final answer:
To lose 1 lb/week, you need to decrease your daily calorie intake by approximately 500 calories.
Step-by-step explanation:
To lose 1 lb/week, you need to decrease your daily calorie intake by approximately 500 calories. This is because to lose 1 lb of weight, you need to create a calorie deficit of 3,500 calories, which is achieved by reducing your calorie intake by 500 calories per day. For example, if you currently consume 2,000 calories per day, you would need to decrease that to 1,500 calories per day to achieve a calorie deficit of 500 calories and lose 1 lb/week.
