what are meal replacement shakes?

typically, men and women replace one or more meals to satisfy calorie intake for a given day. however, it’s essential to know what your recommended calorie intake is to make this work. not all meal replacement shakes supply the same number of calories or grams of protein, carbohydrates, or fats.

all meal replacement shakes we’ve come across are formulated with a protein base. the protein may come in the form of commonly used whey protein, or less conventional sources like eggs. within the whey protein category are a variety of different types of whey, including casein, isolate, and concentrate.

the protein base for meal replacement shakes can also come in plant-based varieties. sources of plant-based protein include hemp, pea, and rice, among many others.

mrps vs. other meal replacement products

except for real food, mrps are neither inferior nor superior to other meal replacement protein products.

protein shakes and protein powders are very similar in that they often contain a minimal amount of micros and macros or none at all. protein shakes, and protein powders are just protein that you add to other concoctions, such as homemade shakes and smoothies.

many whey protein products contain lower carbs, vitamins, minerals, and essential fatty acids. but, there are exceptions.

mrps are preferable to other engineered protein shakes if you specifically want a healthy source of protein that can replace all the nutrients of an actual meal.

according to cnn, mrps “can sometimes be a great way to jump-start weight loss because they are portion-controlled, high in protein and low in sugar,” states rachel lustgarten, a registered dietitian at new york city’s weill cornell medical college.

although mrps are viable alternatives to real food, they still do not compare to real food. real whole foods contain vast arrays of nutrients, nutritional compounds, and antioxidants in very unique ratios that are crucial to proper absorption.

bottom line: some mrps are different from protein shakes, meal replacement powders, and whey. mrps constitute a complete meal, whereas some protein shakes, powders, and whey serve a specific purpose.

“these meal replacement shakes were not my favorite. i had a hard time drinking them unless i blended them with ice and almond milk. they also tasted ok with frozen strawberries blended in. for the price, i would not purchase these again.”

“tastes great, and as a substitute for a couple of meals a day, a real aid for taking off a few pounds. i have one for breakfast and take one to work along with a couple of snacks like fruit and celery sticks. it actually does hold me ’till dinner. i use slim fast usually five days a week while working for convenience and eat moderately on the week end. that way i never get tired of it, but i can feel that i’ve lost some of the bloat from staying at home recently. highly recommended as a tasty and healthy meal replacement!”
