Meal replacement shakes?
Yeah, they’re pretty trendy right now.
But do they really work? And are they really just as healthy as eating a nutritious meal?
Meal replacement supplements are intended to substitute your solid meals, helping you track exact amounts of nutrients and calories you consume.
They usually come in the form of powder to be made into shakes, smoothies and iced drinks. Some meal replacement supplements are medically prescribed and these usually include more than just your required minerals and vitamins.
The top meal replacement brands usually contain about 200 to 250 calories per serving, fortified with lots of added minerals and vitamins. Most even offer low sugar options.

How do meal replacement shakes work?
Meal replacement supplements are prepared products that you take once or twice a day in the form of shakes, bars, or smoothies. They substitute one of your main meals like breakfast, lunch or dinner.
They have the recommended quantity of carbohydrates included in each meal along with fats, proteins, vitamins and minerals.
In addition, meal replacement supplements contain added fiber in order to fulfill your daily recommendation. They also provide a convenience to appease hunger in times when you do not have time to prepare a regular meal.
Meal replacement supplements are primarily used for weight loss. One of the best benefits of meal replacement shakes are that they are loaded with targeted quantities of vitamins and minerals, allowing you to monitor each nutrient that you consume throughout the day.
You don’t have to consume an array of vegetables, whole-grains and fruits to get your daily intake of essential nutrients. Meal replacement supplements are a convenient way to get the recommended vitamins and minerals that you need without worrying about preparing meals, or the cleanup after.
They are also typically high in protein. You can get all the needed vitamins and minerals while consuming only a few grams of fat and a small amount of calories. Almost sounds too good to be true, right?
What are the side effects of meal replacement shakes?
Meal replacement supplements provide around 200 calories for each serving. Drastically cutting your calories down with meal replacement supplements can make you feel tired and fatigued throughout the day if you do not get enough calories to sustain your daily activity levels (you might want to try a nootropic).
Your digestive tract may also suffer by replacing a couple of meals a day with meal replacement supplements.
According to Linus Pauling institute report, women need 26 grams of fiber while men need as much as 38 grams of fiber throughout the day (1).
Meal replacement supplements generally don’t contain much fiber which could make it hard for you to reach your daily fiber intake recommendation. As a result, you may suffer from diarrhea, bowel irregularity or constipation.
Meal replacement supplements could also affect your satiety (2). Because these supplements do not contain much fiber, you do not get the feeling of being full and you do not get the chewing benefit from having a meal.
With a shake, you may consume it quicker than a meal, reducing your satiety and causing you to feel the hunger again shortly after.
Whey protein is the main ingredient of many meal replacement supplements that are not lactose free. People who are lactose intolerant should avoid these particular nutritional shakes as they may suffer stomach discomfort, nausea, cramps and bloating.
Some commercially produced meal replacement drinks contained traces of arsenic and even harmful heavy metals such as cadmium, mercury or lead, according to one study published in 2010 by Consumer Reports (3).
Consuming products with these heavy metal ingredients can result in health problems such as weakness, joint and muscle pain, fatigue, headaches and constipation.
Meal replacement supplements could also cause serious side effects for those that have kidney or liver problems, and they can negatively interact with diabetes medications.
Meal replacement shakes are the best way to substitute a meal for a nutrition drink and still gain all the nutritional benefits.
