Best Time to Drink a 1000 Calorie Smoothie:

The timing of drinking this high calorie shake for weight gain does matter.

The best time to drink this smoothie is for breakfast.

It will fill you up, and provide you with lots of nutrients, including macronutrients, vitamins, and minerals. 

Because the smoothie is high-calorie, you are starting the day with almost half of your daily calorie requirement

This is great if you are trying to gain weight. 

Alternatively, if you are someone who works out, it can be a good idea to drink it half an hour before hitting the gym.

This will give you the energy you need to power through. 

Tasty 1000 Calorie Shake Variations

1000 calorie smoothie

I recently made a 3000 calorie shake, 2000 calorie smoothie, so I got some experience in creating high-calorie shakes for weight gain.

Each of these recipes went through multiple different variations, some I found quite tasty, others not so much.

The variations that were just as tasty, which you could try, include:

#3. The Smoothie Base Substitutions:

The original recipe contains full-fat dairy milk. 

But, if you are lactose intolerant, you can use the following alternatives:

  1. Coconut Milk
  2. Oat Milk
  3. Rice Milk
  4. Almond Milk
  5. Soy Milk

Do note, that if you are lactose intolerant, you may want to use a milk-free protein powder too!

#2. The Protein Powder 

I used grass-fed whey protein powder, but you have many different options.

Some different protein powders I tested that worked well in the smoothie included:

  1. Pea Protein Powder.
  2. VEGA Chocolate Protein Powder.
  3. Collagen Powder.
  4. Brown Rice Protein Powder (Unsweetened).

If you dislike chalky-tasing protein powders, I suggest that you use collagen or brown rice protein powder.

#3. Fruits

Not everybody likes bananas, so here are your alternatives to make this fruit weight gain smoothie:

  1. Frozen Mango Chunks.
  2. Frozen Pineapple Chunks.
  3. Frozen Mixed Berries.
  4. Frozen Cherries (Work great with the chocolate).
  5. Canned Peaches.

High Calorie Smoothie Frequently Asked Questions:

How Do I Make This 1000 Calorie Shake Vegan?

Making this smoothie vegan is really easy, all you need to do is ensure you use vegan protein powder (e.g pea protein) and dairy-free milk (e,g oat milk).

How Do I Store This Smoothie?

The best way to store the blended smoothie is in the fridge. Either use an airtight container, or a portable water bottle, tightly sealed. Consume the smoothie within 24 hours.

I Don't Like Chocolate - What Can I Use Instead?

For a non-chocolate version, swap the cocoa powder for peanut butter powder, extra oats, extra protein powder, or instant coffee.
