Adjust to fiber shakes. If you normally don't get much fiber in your diet, drinking high-fiber protein shakes can initially cause some gas and bloating. That doesn't mean you should avoid shakes containing fiber since fiber offers all kinds of health benefits and most of us need to get more in our diet. Instead, have a quarter serving of shake on the first day, have a half-serving the next day or so and gradually increase to a full shake serving in 5 to 7 days. By letting your body adjust the added fiber should not cause you any discomfort.
Not so frothy. The longer you blend your shake the more air you whip into it and the more air you'll swallow. Make your shake super-smooth and you won't walk around afterwards feeling bloated.
Slow down. Quickly gulping down your shake can leave you uncomfortably gassy and bloated. The solution: Sip more slowly and you won't swallow as much excess air.
Tip: While a protein shake is fine as an occasional meal replacement, keep in mind that shakes are not nutritionally equal to a healthy meal such as grilled chicken breast with a baked potato and a side salad. Protein shakes are helpful as a protein booster, but always turn to food first as your main provider of essential vitamins and minerals.
