Can Meal Replacement Shakes Actually Replace Breakfast, Lunch, and Dinner?
Registered dietitian Kylie King evaluates the pros and cons of using meal replacement shakes for weight loss and nutrition. Are they a healthy substitute?
POLICY WIRE — New York, USA — As the protein-maxxing trend gains momentum, with Circana’s Eating Patterns in America study revealing that over 48 percent of American adults are actively increasing their protein intake, many are turning to liquid nutrition. Amid a national weight loss craze driven by GLP-1 medications, registered dietitian Kylie King is cautioning consumers to approach meal replacement shakes with careful consideration.
King, who has spent over 15 years specializing in behavioral weight loss, notes that high-quality meal replacements are designed to provide a balanced profile of calories, protein, carbohydrates, and essential vitamins. She often suggests them to clients who struggle with skipping breakfast, as they offer a convenient way to maintain energy levels until the next meal.
The convenience factor is a significant benefit, as shakes require no preparation and are easily portable for busy schedules. Furthermore, a 2019 University of Oxford review of clinical trials indicated that incorporating meal replacements into a weight-loss strategy can lead to greater weight reduction over a one-year period by simplifying calorie tracking.
However, King warns that liquid calories often fail to provide the same level of satiety as solid food. Because drinking requires no chewing, the body has less time to register fullness, which can lead to hunger shortly after consumption. To combat this, she suggests pairing a shake with a crunchy snack like fruit to trigger the brain’s satiety signals.
While the American Diabetes Association acknowledges that meal replacement plans can be beneficial for managing diabetes under professional guidance, King advises against long-term, low-calorie, shake-only diets. She emphasizes that these products should serve as a short-term tool rather than a permanent lifestyle change, as they do not teach the necessary habits for long-term weight maintenance.
Individuals with kidney disease, diabetes, or those on specific medications should consult their healthcare team before making dietary changes. When selecting a product, King recommends looking for options that match your specific caloric needs, contain a fiber boost, and include no more than 10 grams of added sugar.
