Question: Is it healthy to lose weight this fast after weight loss surgery?
Dr. Rodrick McKinlay’s Answer:
Most weight loss surgery patients are excited to see excess pounds shed quickly in the first few months after surgery. It is usual to lose 50 pounds in the first three months after surgery, or substantially more for severely obese patients. But many patients wonder, am I losing weight too fast?
In general, you are much healthier at a significantly lower weight, regardless of how fast you lost the weight. You can be healthy and lose weight fast, up to 10 pounds a week right after surgery. This weight loss will slow down as time progresses. But you must follow principles of hydration and good nutrition to ensure the healthiest weight loss possible.
Ideal hydration means drinking at least 64 ounces of water a day, but you may need more on hot summer days, during exercise, or if you have a fever. If you are drinking less than 32 ounces of water a day, you may need to have IV fluid support in the first month or two after surgery.
Good nutrition means following the guidelines you received at surgery: eat 70% protein and 30% vegetables. By eating the protein portion first, you are sure to provide your body with the fuel it needs to keep all its essential functions running smoothly.
Another common question from patients has to do with weight loss plateaus—periods of time (up to one or two weeks) where you may not lose a pound. This is simply your body taking time to “catch up,” slowing its metabolism a bit, before you begin to lose weight again. Just remember to stick to the dietary guidelines, and weight loss will continue in a healthy way.
