Answer
Manufacturers of
protein shakes may claim that their products decrease body fat or promote weight loss. But there is no evidence that this is true.
Most
protein shake mixes and some pre-made shakes get their
protein from soy. Others may use a dairy or egg base. Although
protein shakes generally aren't harmful, you shouldn't expect them to take the weight off for you. Remember,
protein contains calories. So consuming too much
protein can actually make losing weight more difficult.
Weight loss is achieved by controlling your calorie intake and increasing the number of calories you burn through physical activity. So you have already made two very positive changes.
Eating a source of
protein as part of a meal or snack is a good idea. You'll likely feel satisfied longer, which means you're likely to consume less calories overall. Occasionally having a
protein shake with added vitamins and minerals as a meal supplement is better than skipping a meal. However, these types of shakes — even if the labels shows added nutrients — do not replace all of the benefits of whole foods, such as fruits and vegetables.
The average adult needs 46 to 56 grams of
protein a day; however, this number varies depending on your body weight and overall health. As long as you're eating a healthy, balanced diet, adding extra
protein — such as in the form of
protein shakes — isn't necessary.
