72-Hour Fast Calculator

Formula

To calculate the estimated weight loss:

$\text{Estimated Weight Loss (lbs)} = \text{Current Weight (lbs)} \times \text{Weight Loss Factor} \times \text{Activity Multiplier} \times 3$

To calculate the hydration needs:

$\text{Total Hydration Needs (liters)} = 3 \times 2.7$

What is a 72-Hour Fast?

A 72-hour fast involves consuming only water for 72 hours. This practice is believed to have various health benefits, including improved insulin sensitivity, reduced inflammation, and weight loss[^1^][^2^].

Example Calculation 1

Let's assume the following values:

Current Weight = 180 lbs
Gender = Male
Activity Level = Moderate

Using the formula:

$\text{Estimated Weight Loss} = 180 \times 0.02 \times 1.2 \times 3 = 12.96 \text{ lbs}$

$\text{Total Hydration Needs} = 3 \times 2.7 = 8.1 \text{ liters}$

The estimated weight loss is 12.96 lbs, and the total hydration needs are 8.1 liters.

Example Calculation 2

Let's assume the following values:

Current Weight = 150 lbs
Gender = Female
Activity Level = Light

Using the formula:

$\text{Estimated Weight Loss} = 150 \times 0.015 \times 1.1 \times 3 = 7.43 \text{ lbs}$

$\text{Total Hydration Needs} = 3 \times 2.7 = 8.1 \text{ liters}$

The estimated weight loss is 7.43 lbs, and the total hydration needs are 8.1 liters.
