Keeping muscles healthy and optimizing their repair post-training is extremely important to maximize athletic performance. In addition, it is desirable to increase muscle mass for many sports, reduce body fat, and gain strength. Gainers are one of the popular supplements to build muscle among fitness lovers.
Every individual has different nutritional requirements depending upon several factors like age, height, gender and intensity of physical activity.
Body type also plays a substantial role in determining calorie needs. Body type is broadly categorized under three types based on body composition – ectomorph, mesomorph and endomorph. People with mesomorph body types have athletic musculature and can gain or lose mass quickly, while endomorphs have a slow metabolism naturally. They can gain fat easily but struggle a lot to lose.
Gainers are specifically beneficial for people with ectomorph body types who are hard gainers because of their fast metabolism. Gaining weight and building muscle mass is quite challenging for them.
Gainers are of two types – mass gainer and weight gainer. Both work for different body types, yield different results and differ in their nutritional composition. Although they look relatively similar, there is a lot of difference.
Mass Gainer
A mass gainer protein supplement is rich in calories, proteins, carbs and fats. It also provides dietary fibre, vitamins and minerals and is typically used to gain muscle mass. Usually, mass gainers contain carbs and protein in the ratio of 3:1 and 2:1. They combine high-quality protein sources with complex carbs for muscle building and workout recovery.
Weight Gainer
Weight gainers are recommended for people that aim to increase their body weight through high-calorie consumption. The high amount of carbs and proteins present in weight gainer shakes help increase both muscle and fat. The number of calories per serve is high in weight gainers compared to mass gainers and usually ranges between 700-1300 kcal in a weight gainer.
