Check out our picks for the best protein powder for weight loss uk
The right protein powder can be genuinely useful when you’re trying to lose weight; helping to keep you feeling fuller for longer, meet your protein target for the day, and support your efforts in the gym.
But with so many different options to choose from it can be hard to know which protein powder to pick. Don’t worry though, we’ve done the hard work for you and put together this guide to the best protein powder for weight loss UK.
So let’s get into it.
Picking The Best Protein Powder for Weight Loss UK
When we were looking at the best protein powder for weight loss UK options, protein content was obviously a big factor.
Protein can help keep you feeling fuller for longer, which is always useful when you’re trying to stay in a calorie deficit without feeling like you’re constantly wanting to raid the snack cupboard.
So we were looking for powders that packed in a good amount of protein per serving, but didn’t also come with loads of extra calories.
Because realistically, a protein powder for weight loss needs to help you hit your protein target while still fitting into your daily calories.
So here are our top 3 picks for the best protein powder for weight loss UK.
Purition Casein Protein
First up in Purition’s Casein Protein, which is a slow-release, dairy-based protein powder.
Each 25g serving gives you an impressive 23g of protein for just 93 calories, so it really is a great option if you’re looking to lose weight.
And the fact that this is casein protein means that it digests more slowly, giving your body a steady release of essential amino acids to support muscle maintenance and overall health.

That makes it a good option for between meals or in the evening, especially when you want something that keeps you feeling satisfied for a bit longer. And when you’re trying to lose weight, that can make a big difference, because staying full is often half the battle.
It’s also heat stable, so you can stir it into warm porridge, hot chocolate, protein coffee or a bedtime drink without ruining the benefits.
Price: £18

Myprotein Impact Diet Whey
Next up is Myprotein Impact Diet Whey, which is a diet protein powder made for anyone who wants plenty of protein without loads of sugar.
Prices start from £10.99 for a 420g pouch and it comes in flavours including Chocolate, Cafe Latte, Banana and Natural Vanilla.

There’s also an unflavoured option that gives you 35g of protein per serving with just 2.1g of sugar, which makes it a strong pick if you want something that can support weight loss while still helping you hit your protein target.
It also contains choline to support metabolism, which gives it a more goal-focused feel than a standard whey protein. And because it’s quick and convenient, it’s an easy one to use after training, between meals, or whenever you need a simple protein boost.

Optimum Nutrition Gold Standard 100% Whey Protein
Last up is Optimum Nutrition Gold Standard 100% Whey Protein, which is a proper classic for a reason.
Each serving gives you 24g of high-quality, fast-absorbing whey protein for less than 120 calories, with low sugar too. So for anyone trying to lose weight, the appeal is pretty clear. You’re getting a reliable protein boost that can work after training, between meals, or just as an easy way to help hit your protein target for the day.

It also contains 5.5g of BCAAs per serving to support muscle repair, which is useful if you’re training regularly while trying to bring your calories down. Losing weight doesn’t mean you want to lose sight of recovery, especially if you’re still lifting, doing classes or keeping your workouts consistent.
There are more than 15 flavours to choose from too, including Banana Cream, Chocolate Hazelnut and Delicious Strawberry.
Price: £25 for a 15-serving pack
