What are some meal replacement smoothies for dinner?

Quick answer

A dinner smoothie works best when it has a protein source (yogurt, kefir, milk, soy milk or silken tofu), a fat or fiber source (oats, nut butter, seeds, avocado) and some fruit or vegetables. The NHS says smoothies count as only one 5 A DAY portion, capped at 150 ml a day, and advises drinking them at mealtimes. Treat a smoothie dinner as an occasional meal, not a daily habit.

What makes a smoothie a meal replacement?

A fruit-only blend is a drink, not a meal. To feel like dinner it needs protein, some fat and fiber, plus fruit or vegetables for flavor. This is general guidance, not a diet plan, and needs differ by person.

  • Liquid base: milk, soy milk, unsweetened plant milk, kefir or water.
  • Protein: plain yogurt, kefir, silken tofu, milk or soy milk, or a protein powder if you use one.
  • Fiber and fat: rolled oats, chia or flax seeds, nut butter, avocado.
  • Produce: frozen berries, banana, mango, spinach or kale.

Which smoothies work for dinner?

Idea Blend
Berry oat Milk or soy milk, plain yogurt, rolled oats, frozen mixed berries, a spoon of nut butter
Green Spinach, banana, pineapple, plain yogurt or kefir, chia seeds
Peanut banana Banana, peanut butter, milk or soy milk, oats, a pinch of cinnamon
Tropical Mango, pineapple, silken tofu or yogurt, coconut or soy milk

How do you keep it filling?

  • Sip it slowly, or eat it with a spoon from a bowl; a thick smoothie feels more like a meal.
  • Use frozen fruit rather than juice, and skip added sugar, honey or syrup; ripe fruit is usually sweet enough.
  • Include oats or seeds, which add fiber and bulk.

What does the NHS say about smoothies?

The NHS says juice and smoothies count as a maximum of one portion of your 5 A DAY, with a combined limit of 150 ml a day, because blending releases sugars that can damage teeth. It advises having them at mealtimes rather than as a between-meal snack. A large dinner smoothie is therefore well above that guidance, so it is best as an occasional meal, with whole vegetables and fruit the rest of the week.

How often should you have one?

There is no official rule for dinner smoothies. A sensible approach is to have one now and then when you are short of time, and eat a normal cooked meal on most days. A smoothie dinner rarely replaces everything a varied meal offers, so check it contains protein and fiber.

Who should be careful?

Children, pregnant or breastfeeding women, people with diabetes, kidney disease or a history of eating disorders should ask a doctor or dietitian before swapping meals regularly. Do not add raw eggs or unpasteurized dairy.

Making it ahead

Blend just before drinking. If you must prepare it earlier, keep it in a closed container in the fridge and drink it within a day, shaking before use.

People also ask

What can I put in a smoothie to make it a meal?

Add protein (yogurt, kefir, milk, soy milk or tofu), fiber (oats, chia, flax) and some fat (nut butter or avocado) to fruit or vegetables.

Is a smoothie a healthy dinner?

It can be an occasional quick meal if balanced, but the NHS counts smoothies as only one 5 A DAY portion and limits them to 150 ml a day, so they should not replace whole fruit and vegetables regularly.

When is the best time to drink a smoothie?

The NHS advises having smoothies with meals rather than as snacks between meals, to reduce the risk of tooth decay.
