Energy-Dense Meal Replacement Shakes

With all the focus on weight loss in our society, it can be surprisingly difficult to find healthy ways to gain weight. Though the process seems like it should be simple enough, many types of weight gain are actually quite harmful, even if they happen on purpose. For this reason, the method of weight gain arguably matters more than the number that pops up on the scale two or three months down the road. When trying to gain weight, it’s important to rely on well-rounded products that nourish the body as a whole, rather than foods that are simply high in calories; remember, gaining weight should be a thoughtful endeavor, not a headlong rush toward a bigger bod. That’s why weight gain shakes from ENU feature a wholesome mix of protein, fats, and carbs, along with two dozen vitamins and minerals. Learn more about how ENU weight gainer shakes can help you gain weight by visiting us online or calling (855) 266-6733 today.

Patients Who Can Benefit from Healthy Weight Gain Shakes

Weight gain shakes can offer an array of benefits to patients with certain conditions. If you suffer from one of the following ailments, consider taking advantage of the protein shakes for weight gain available from ENU.


For some patients with diabetes, weight gain is a must, but it can be tough to put on pounds while observing the dietary restrictions required to manage diabetes. Weight gainer drinks made with complex carbs, healthy fats, and lots of protein are a good choice for diabetics because they won’t cause a harmful spike in blood sugar.

Cancer and Chemotherapy

Patients undergoing chemotherapy and other forms of cancer treatments often have difficulty maintaining a healthy weight and keeping up their strength during the process. A good weight gain shake can help provide nutritional support for cancer patients in a convenient and effective way.

Eating Disorders

A variety of mental illnesses and eating disorders can cause unwanted weight loss, making it necessary to gain that weight back in a healthy way. High-calorie shakes for weight gain can make it easier to meet your calorie goals and put on some pounds if you have an eating disorder.


Older adults often experience weight loss, which can prove dangerous if left unchecked. Provided they have plenty of calories and protein, weight gain shakes for seniors can help older adults maintain strength and muscle mass for improved health and independence.


Protein shakes for athletes have long been a major tool for promoting muscle recovery and building mass. ENU weight gain shakes offer 20 grams of protein from whey and soy so that you can boost your gains and keep your body energized at the gym or on the field.

Underweight Treatment

Though less common than being overweight or obese, being underweight often comes with its own share of serious health problems. If you’re underweight and struggling to put on some pounds, try adding a healthy weight gain shake to your daily routine.

How to Gain Weight in a Healthy Way

For those who want to gain weight, it can be tempting to simply load up on high-calorie sweets and snacks in a delicious effort to pack on some pounds, but this method should be avoided for several reasons. Not only is excessive sugar and fat – especially saturated or trans fat – bad for you, but any weight gained in this way will likely take the form of unhealthy visceral fat, which sits around your midsection and can contribute to a number of medical issues. In addition, trying to gain weight (or lose it) too quickly can result in a whiplash effect: Whether because of changes to their diet or shifts in their metabolism, people who put on weight quickly and purposefully tend to see that weight disappear just as fast.

Though the factors affecting weight gain can be quite complex and vary from person to person, the foundation of any change in weight is a straightforward formula: Take the number of calories you consume, subtract the number your body uses, and you end up with the number of calories your body is gaining or losing each day. For instance, someone whose body burns 1,800 calories in a day might consume 2,000 calories over that time, giving them a net gain of 200 calories that their body will store and adding to their overall weight. Generally speaking, health experts recommend gaining weight at a rate of no more than 1-2 pounds per week; because a pound of fat is worth about 3,500 calories, this translates to about 500 extra calories per day.

The ideal method of increasing your calorie count is to balance high-calorie ingredients with a mix of nourishing macronutrients and gain weight at a slow and steady rate. The aim should be to increase muscle mass at least as much as body fat; not only is muscle denser than fat – which means more weight by volume – but it is more likely to stick around in the long term, and it’s a healthier addition to your body.

Important Nutrients to Look for in a Weight Gainer Drink

With so many weight gain shakes to choose from, picking the best one can seem like a daunting task. When you’re browsing the shelves of your local supermarket or searching the Internet for the right weight gainer drink, look for the key nutrients outlined below.

Plenty of Calories

Although it’s far from the only factor you should look at, the number of calories in your weight gainer drink matters greatly. Maintaining a calorie surplus is what ultimately determines your rate of weight gain, and keeping track of your calorie intake is a handy way of monitoring progress. When seeking out the best protein shakes for weight gain, look for products with several hundred calories, as these will be the most effective, but also be sure to check the ingredients list. You’ll want to select a gainer shake that offers a well-rounded mix of the major macronutrients from healthy sources, such as those discussed below.

Effective Protein

Arguably, the most important nutrient to look for in a weight gainer drink is protein, because it’s the nutrient that promotes the kind of healthy weight gain that you should be striving for. Although putting on fatty mass is largely unavoidable – and, in some cases, actually beneficial – when gaining weight, you’ll also want to build up some muscle mass, which means getting plenty of protein.

Not all protein is equally effective, however. Many plant-based sources of protein are considered “incomplete,” meaning that they lack one or more of the essential amino acids your body needs (sources like soy and quinoa are exceptions). In addition, some sources of protein are less easily absorbed, leaving some of its amino acid content to go to waste. When looking for the best protein shakes for weight gain, keep an eye out for ingredients like protein isolates, which are more easily digested and gentler on the system than whole proteins. Whey protein isolate, in particular, is effective because it’s a complete protein that’s easily absorbed.

Healthy Fats

As the most calorie-dense macronutrient, fats are a common ingredient in weight gain shakes, but the type of fat in your shake makes a big difference. In recent years, nutritional research has shown that saturated and trans fats are hugely detrimental to a person’s overall health because they raise the levels of LDL cholesterol in the blood and increase your risk for cardiovascular disease. It’s for this reason that you should look for sources of unsaturated fats in your weight gainer drinks.

A good rule of thumb is to consider whether the fat source is liquid or solid at room temperature; the liquid sources, such as olive oil or coconut oil, are the unsaturated fats you want. Not only can these fats provide plenty of calories in a healthy weight gain shake, but they can also improve your heart health and reduce the risk of developing type 2 diabetes.

Complex Carbs

Like fats, carbs are a main source of calories in many weight gain shakes, and as with fats, the type of carb is important. Sources of simple carbs, such as sugar and corn syrup, are often added to shakes as a way to cheaply boost the calorie count of a weight gainer drink, but these ingredients have little to no nutritive value and can actually be harmful to your health. The best protein shakes for weight gain include complex carbs instead of simple ones, so check the ingredients list before buying the first high-calorie shake for weight gain that comes along.

Using Protein Shakes to Gain Weight

Protein shakes can be extremely helpful for gaining weight, but they must be properly applied if you want to see results. Keep in mind that weight gain shakes are not magic potions that can simply make new weight appear where it’s needed; they’re tools in your arsenal, and as with any tool, it helps to know how to use them.

When adding a gainer shake to your regimen, remember that the goal is to boost your overall calorie count so that you are taking in more calories each day than your body is using. If you’re not careful, protein shakes for weight gain can have the opposite effect, since protein tends to increase feelings of satiation – that feeling of fullness you get after eating. Even the best weight gain shakes can undermine your efforts if you throw one back before sitting down to eat, because the protein in them can make you less hungry and, therefore, less inclined to finish your meal. In other words, improperly using a protein shake for weight gain can actually reduce the number of calories you consume overall.

The best strategy for the effective use of weight gainer shakes is to treat each shake as a supplement to a meal, rather than as a replacement. One easy way to add a healthy weight gain shake to your diet is to drink a shake after a meal; simply sit down to breakfast, lunch, or dinner and eat as much as you normally would, then add a shake at the end for a boost in calories and key nutrients. Another option is to drink a shake as a healthy snack during the day, though you should be careful to leave time between the snack and your next meal to avoid dampening your appetite.

As part of a weight gain diet, it’s typically recommended that you engage in regular exercise and build up some muscle mass, a goal that’s more easily achieved with the help of a protein-rich weight gainer drink. After a workout, your body will kick its muscle-production process into high gear, but you can only take advantage of this boost if your body has the resources it needs – namely, the amino acids in protein – to create new muscle tissue. If you exercise or go to the gym, try drinking your protein shake immediately after finishing to supply those essential resources and see the best possible results in terms of muscle growth.

Whatever method of weight gain you choose, make sure to pick a well-rounded nutritional shake, not just one with a certain amount of protein. ENU nutritional shakes contain 20 grams of protein from whey and soy, but they also offer complex carbs derived from whole grains and heart-healthy fats. Plus, each shake features a blend of more than 20 vitamins and minerals to support your body’s systems, and at 400 calories per carton, one ENU weight gain shake will have you well on your way to meeting your calorie goals for the day.
