Weight Regain Calculator

How to calculate weight regain percentage?

Calculating weight regain as a percentage of weight lost provides a more accurate picture of maintenance success than just looking at the total pounds regained. This approach tracks your current status as a ratio of the total weight you successfully lost from your starting point.

Regain % = ((Current Weight - Low-point Weight) / (Baseline Weight - Low-point Weight)) * 100

Using the regain calculator: an example

To illustrate this, let's look at a scenario where a person has a baseline weight of 220 lbs, achieved a low-point of 170 lbs, and their current weight is 185 lbs.

Step-by-step calculation:

1. Total Weight Loss: 220 lbs - 170 lbs = 50 lbs lost initially.
2. Total Weight Regain: 185 lbs - 170 lbs = 15 lbs regained since the low-point.
3. Regain Percentage: (15 lbs / 50 lbs) * 100 = 30% weight regain percentage.

Frequently Asked Questions

Why is regain percentage more useful than just pounds regained?
A 10-pound gain is much more significant if you only lost 20 pounds (50% regain) compared to if you lost 100 pounds (10% regain). The percentage places the gain in the context of your overall weight loss achievement.

What is a normal amount of weight fluctuation?
It is normal for weight to fluctuate by 1-5 lbs day-to-day due to water retention, salt intake, glycogen storage, and inflammation from exercise. These are not necessarily signs of fat regain.

What is considered a 'Low-point Weight'?
Your low-point weight is the lowest stable weight you achieved at the end of your weight loss phase, before beginning your transition to long-term maintenance.
