Question 1

Which ideal weight formula is most accurate?

Accepted Answer

No single formula is universally most accurate. Hamwi and Devine are common in clinical settings, while Robinson and Miller can give slightly different estimates. That is why this tool shows all four, so you can see a realistic range. Your healthcare provider can help you set a target based on your body composition and health history.

Question 2

How much weight do people lose on GLP-1 medications?

Accepted Answer

In clinical trials, GLP-1 medications have helped people lose roughly 15 to 25 percent of body weight over 12 to 18 months, though individual results vary a lot. A healthy BMI range (18.5 to 24.9) is often a better frame than a single number. This is general information, not a prediction for any individual.

Question 3

Should my ideal weight change if I'm building muscle?

Accepted Answer

Yes. These formulas do not account for muscle. If you are strength training while on a GLP-1, your healthy weight may be higher than the formulas suggest, because muscle is denser than fat. Focus on body composition rather than the scale alone.

Question 4

What weight should I aim for after stopping GLP-1 medication?

Accepted Answer

Many people regain some weight after stopping. Building sustainable habits while on medication, such as movement, adequate protein, and consistent eating patterns, can help. Aiming to stay within your calculated healthy range, and working with your provider on any tapering plan, is a reasonable approach.
