Add milk and coconut milk in the shaker cup (850-1000 calories)
Coconut milk is full of healthy fats and is very calorie-dense. Open a can of coconut milk and pour it in your shaker cup. Most people are worried about saturated fat; however, you do not need to worry because saturated fat is always healthy in coconut and other such sources. You may now add whole milk in the shaker cup. Due to the quantity of powder, it is likely that you will need two cups and a blender. You need to keep in mind that you are looking to gain weight and there is no need to skimp on the calories with skimmed milk.
Add whey protein (250 calories)
You can now add 40 to 60g of muscle-building protein, which is going to help you gain weight.
Add oil (250-375 calories)
At this stage, you can now add some oil. It is highly recommended that you use 3-6-9 oil, which is rich in Omega-3 content. Keep in mind that oils are always calorie dense and lack of omega-3 can hamper your muscle growth.
Add carbohydrate powder (200-400 calories)
Add one or two scoops of Maltodextrin powder, which is flavourless and is considered to be a great source of carbohydrates. Depending on how much weight you wish to gain, you may increase more powder.
You can now close the lid on your shaker cup before shaking it thoroughly. Shake until all the powder has been dissolved.
