Best Protein Waters for Bariatric Surgery Patients

Protein infused waters are another form of excellent high-protein alternative to whey protein shakes. They don’t need to be shaken or prepared, they taste delicious, and are easy to consume. Don't get this confused with protein shakes because that is something different.

During and immediately weight loss surgery we are required to drink clear fluids. This can be tricky as people think protein shakes and waters are the same. I tried searching for comparisons online but couldn't find any so I bought several brands and wanted to share my results. When choosing protein water for bariatrics, pay special attention to calories, protein, sugar, carbs and no sparkling or FIZZ.

They are great solutions for when you tired of bland shakes and need to change things up. At some point later down the road you can mix it with vodka for a guilt free cocktail!
