1. What is a 2.5 lbs/week Weight Loss?

A 2.5 pounds per week weight loss is considered an aggressive but potentially sustainable rate of weight loss for many individuals. It requires creating a daily caloric deficit through diet and exercise.

2. How Does the Calculator Work?

The calculator uses the following formula:

Where:

• 2.5 — Target weight loss per week (lbs)
• 3500 — Calories in one pound of fat
• 7 — Days in a week

Explanation: To lose 1 pound of fat, you need a 3500 calorie deficit. For 2.5 pounds per week, this translates to a 1250 calorie daily deficit (2.5 × 3500 ÷ 7).

3. Importance of Sustainable Weight Loss

Details: While 2.5 lbs/week is achievable for some, it's important to consult with a healthcare provider before beginning any aggressive weight loss program. Very low calorie diets should be medically supervised.

4. Using the Calculator

Tips: Enter your current weight and goal weight in pounds. The calculator will show the required daily caloric deficit and estimated time to reach your goal at 2.5 lbs/week.

5. Frequently Asked Questions (FAQ)

Q4: What if I can't maintain this deficit?
