Why Weight Gain Shakes?

For those needing concentrated calories and nutrients in a small volume, weight gain shakes can support increasing body size in a balanced, convenient way.

Calorie density
Weight gain shakes are designed to pack many calories into a small, drinkable volume. This makes it easier to consume extra calories needed to fuel weight gain.

Protein content
Most shakes contain 20-30 grams of protein per serving to support muscle building in addition to the high-calorie content.

Nutritional balance
Shakes aim to provide balanced protein, carbs, and fat ratios for well-rounded nutrition. Some also contain vitamins and minerals.

Appetite stimulation
The liquid calories can stimulate appetite and allow larger solid meals to boost calorie intake further.

Shakes are portable, ready to drink, and require minimal prep, facilitating compliance with recommended intake.

Flexible usage
It can be used as a meal, snack, or supplement to food intake, whichever need is greatest for an individual.

Taste appeal
Shakes aim to taste good, using flavors like chocolate, vanilla, and strawberry to make drinking calories enjoyable.

Types of Weight Gain Shakes

Whey protein shakes
Contain whey protein isolates from dairy/milk. Fast-digesting and absorbed. Better for lean muscle gain.

Casein protein shakes
Use slow-digesting casein protein from dairy. Help build muscle overnight while sleeping.

Meal replacement shakes

Plant-based protein shakes

Factors to consider when choosing weight gain shakes

Added vitamins/minerals prevent potential deficiencies when increasing calorie intake.

Sugar content
Limit added sugars, which provide empty calories. Under 25g per serving is best.

Natural ingredients
Shakes with fewer artificial additives, preservatives, and fillers are healthier choices.

Lactose tolerance
If you are lactose intolerant, choose shakes with vegan protein sources.
