6 tips to increase your protein intake

Protein is an essential nutrient that plays a vital role in the growth and repair of our body's cells and tissues and is critical to maximizing strength and muscle growth during a strength training program. Although most people hit the Recommended Daily Allowance (RDA) of protein, which is 0.8g/kg of bodyweight per day (1), it is well established in the literature that this quantity is inferior for maximizing results from strength training, and as a result, consuming upwards of x2 the RDA of protein has been demonstrated to maximize strength training results (1,2). The question then is, does eating beyond this amount produce superior results?

In the most recent meta-analysis examining healthy adults published in the Journal of Cachexia, Sarcopenia and Muscle, Nunes et al. (2022) reviewed the current body of literature of increasing protein consumption and the effects of muscle and strength development. It was the goal of this specific paper to determine if increasing daily protein ingestion contributes to gaining lean body mass. The authors reported data from 74 random control trials on the subject and found consuming additional protein at or greater than 1.6g/kg of bodyweight per day had a slight, but positive effect. It appears a dose-response relationship occurs up to x2 the RDA, where after a tapering effect occurs (1,2).

Given the importance of protein in providing maximal results in a strength training plan, in this blog we are going to focus on ways you can start to consistently reach your target. If you’re struggling to hit your protein goal on a regular basis, here are some tips to help you do so!

1) Include more animal-based protein sources

Animal-based protein sources, such as meat, poultry, fish, eggs, and dairy products are high-quality proteins that contain all the essential amino acids our body needs. In addition to being a great source of protein, these foods also provide other essential nutrients such as iron, zinc, and B vitamins.

Try to include a source of animal-based protein at every meal, for example, adding a hard-boiled egg to your breakfast, having chicken breast or fish for lunch, and enjoying a steak or pork chop for dinner. Specifically, eating between 20-40g of protein per meal is usually recommended (3), which visually equates to about 1/4 of your plate or about the size of your fist.

2) Eat more plant-based protein sources

Plant-based protein sources, such as legumes, whole grains, nuts, and seeds are also excellent options for increasing your protein intake. Legumes, such as beans, lentils, and peas are particularly high in protein and are also a good source of fibre, iron, and potassium.

Whole grains, such as quinoa and buckwheat, are also high in protein, as well as other essential nutrients. Nuts and seeds, such as almonds and pumpkin seeds, make great snacks and can be added to salads or yogurt for a protein boost.

3) Snack on high-protein foods

If you're looking for a snack that will keep you feeling full and satisfied, reach for high-protein options such as beef jerky, nonfat Greek yogurt, low-fat cheese, deli meats, or a handful of nuts. These snacks will provide a boost of protein while also satisfying your hunger.

4) Incorporate protein powder

Protein powder is a convenient way to increase your protein intake, especially if you're short on time or have a hard time getting enough protein from whole foods. There are many different types of protein powders available, such as whey, casein, and plant-based options, so you can choose the one that works best for you.

Of the three aforementioned options, whey protein has been shown to be superior in building muscle vs casein and soy alternatives (4). However, if you have digestive issues with whey protein I recommend choosing a whey isolate protein, where the additional refinement of the protein powder limits the amount of lactose present making it a viable option (5).

5) Try meatless alternatives

If you're looking to reduce your intake of animal products, there are plenty of meatless alternatives that are high in protein. For example, tofu, tempeh, and seitan are all excellent sources of protein for vegetarians and vegans. These options also provide a variety of different textures and can be used in a variety of dishes.
