Your Quick Guide to Low Carb Protein Powders

white jar with whey protein powder

Choosing the best low carb protein powders doesn’t have to be hard with this list.

But, it will help if you understand a little more about protein powders and their role in your health and weight loss goals.

Protein is an essential nutrient in your body for protein synthesis.

This is the process that repairs micro tears in your muscles, making them stronger and potentially larger, (depending on the weight you’re lifting). But, most regular protein powders have carbohydrates and protein.

The protein is for muscle repair, the carbohydrates are to help boost your energy levels after exercise and even prevent your body from burning muscle for energy.

Of course, this increases the calorie count of your protein supplement.

A low carb protein powder has very few carbohydrates which makes them perfect for muscle repair without the fat gain.

When you consume carbohydrates these are converted into glucose in your bloodstream, via the release of insulin. If there is too much glucose in your bloodstream then the excess is turned into fat and stored; for use at a later date.

Of course, if you’re trying to lose weight or show off your lean muscles, gaining fat is not something you want to be doing; that’s why you need the best low carb protein powders.

There are several things you should consider before you invest in your next low carb protein powder;

Reputation

The first thing to check is the reputation of the manufacturer.

You need to be able to trust them and the easiest way to do this is to look at their website for their history and the research they’ve done.

You can then check social media sites to see what other people think of their products. You should get a mixed bag of reviews with more positive than negative.

Finally, check with your family and friends, they may have tried the product themselves.

Pay particular attention if anyone tells you of side effects of a specific powder; they are usually rare and not everyone will get them.

Diet

It is important to consider your current diet. Experts recommend that you consume 0.8 grams of protein per kilogram of your body weight per day.

But, this is for a sedentary person. If you’re exercising, this amount can rise to between 1.2 and 1.5 grams per kilogram.

You can get plenty of protein from your food; consider how much extra you need before you decide how many times a day you need to take the best low carb protein powder for weight loss or muscle gain.

We’ll take a look later at when you should be taking your protein powder.

Proprietary Blends

A quality product will declare every ingredient and the amount of each ingredient. If they don’t declare the amount then the powder has a proprietary blend.

These are best avoided as you don’t know how much of each substance you’re getting; making it very hard to establish how beneficial it actually is.

The main reason for proprietary blends is for the manufacturer to save money; that doesn’t inspire me with confidence that they can be one of the best low carb protein powders.

Avoid Added Sugars

If you’re looking to lose weight or display the muscle you’ve gained, the last thing you need is extra sugars.

Check the ingredients to ensure sugars and sweeteners haven’t been added. Unfortunately, the best tasting low carb protein powder is most likely to be the one with lots of extra sugar in it.

Instead, choose a natural or no flavor and take a look at the FAQs below, specifically how to improve the flavor.

Budget Properly

Protein powders come in all shapes and sizes, as well as an array of prices.

You need to budget for the cost of purchasing these on a regular basis and look at buying the larger containers. These will usually offer you the best cost savings.

When considering the price of protein powder you’ll need to bear in mind that this is simply part of your weekly food bill.

A low carb protein powder is a supplement that helps to ensure you are getting all the nutrition you need.

What Classifies as Low Carb Protein Powder

If you take a look at the average protein powder you’ll see there will usually be approximately 6-10 grams of carbohydrates to every 20 grams of protein.

Roughly 25-30% of the ingredients will be carbs.

A good low carb protein powder will have between 1 and 5 grams of carbohydrates to 20 grams of carbs. You can even find some that have zero carbs.

In short, check the ingredients label before you purchase.

FAQ

To help you understand low carb protein powders, here are the most frequently asked questions, (and answers).

Is whey protein powder low carb?

Yes and no! The answer to this question will depend on the manufacturer and the ingredients they have included.

It is perfectly possible to have a whey protein powder that has 25g of protein and just 3grams of carbs.

However, you can also get whey protein powders with 25g of protein and 10g of carbs; that’s because some are designed as the best protein powders for weight loss and others are designed as the best protein powders for muscle gain.

Again, check the label before you buy.

Is protein powder good for a low carb diet?

Yes! Protein is essential for the health of your body. It doesn’t just help to repair your muscles, it can also help to protect them from being used as an energy source.

This will encourage your body to burn fat and help you to lose weight; which is usually the purpose of a low carb diet.

However, as with any supplement, it is important to remember that it is a supplement and not a meal replacement. It should be used alongside your regular meals and exercise.

The best low carb protein powders when you are trying to lose weight will have a lot of protein, with very few carbs, calories, and fat.

Are low carb protein powders safe?

The majority of low carb protein powders are completely safe. However, most of them do not need to comply with FDA regulations.

This is why it is essential to check the reputation of the manufacturer before you purchase.

You should also be aware that any whey based protein powder can cause issues if you are lactose intolerant; in this case, they won’t be considered safe and you should use a non-whey based powder.

Are there any known side effects of low carb protein powders?

The most common, and generally the only side effect of protein powders is digestive issues. These are generally connected to either lactose intolerance or poor quality whey protein.

If you do experience issues connected with intolerance you’ll likely feel bloated, have gas, stomach cramps and possibly even diarrhea.

On occasion, it can also cause thirst, reduced appetite and occasionally headaches.

Will it really help me to lose weight?

Yes, but only as part of a healthy diet and exercise plan. By itself a low carb protein powder will reduce your calorie and carb intake, encouraging weight loss.

However, to be really effective you need to start eating more healthily and add some exercise into your daily regime. A treadmill is a great starting point as you can walk, jog, or run and do it any anytime of the day or night; regardless of the weather.

When should I take my low carb protein powder?

The instructions on the side of your powder container will tell you when you should take it. Most manufacturers will recommend three times a day:

  • In the morning to boost your metabolic process and get the day started.
  • After you’ve worked out to replace proteins, (and carbs) that have been lost.
  • Before bed to ensure your muscles have the fuel they need while you sleep.

However, if you’re getting plenty of protein in the food you eat then the best option will be to take it once a day during your recovery period.

This is usually defined in the 60 minutes immediately after a workout. It’s the perfect accompaniment to a foam roller recovery routine.

Can I improve the flavor?

It is best to choose no flavor in order to minimize added sugar and carbs. However, this doesn’t mean taking the best low carb protein powders has to be a chore.

You can mix it with milk to improve the flavor or make your own flavor by adding a spoon of peanut butter, fruit, or even mixing it with your oatmeal.
