What's Considered Normal Weight Fluctuation?

What's Considered Normal Weight Fluctuation? If you notice a dramatic change on the scale, chances are it's due to water, says Anita Petruzzelli, M.D. High-carb and high-salt foods can cause water retention and a boost in poundage. Dr. Petruzzelli If the scale shows a seven-pound jump for longer than a day or two, alcohol consumption could be one cause. "Alcohol stimulates your appetite and wrecks your self-control regarding the amount of food that you consume," says Joseph Colella, M.D. Keep in mind that in addition to diet, some medications and health conditions can also lead to weight fluctuation. The bottom line: Weight fluctuation is normal. But if the scale rises five or more pounds for longer than a day or two, chances are it's more than just water weight.
