Protein Intake Recommendations & Expert Guidance

Scientific evidence suggests that consuming excess protein above your requirements is generally safe for most healthy individuals. Your body will simply use what it needs and excrete the excess. However, very high intakes may strain kidneys in people with pre-existing kidney issues. For most people engaged in strength training, consuming 2.0-2.2 grams per kilogram of body weight is considered safe and effective.

While the "anabolic window" concept has been somewhat overstated, consuming adequate protein around your workout is beneficial. Research suggests consuming protein within several hours after resistance training supports muscle protein synthesis. However, overall daily protein intake is more important than precise timing. Spreading protein across 3-4 meals throughout the day is an effective approach.

Both animal and plant-based proteins can support health and fitness goals effectively. Animal proteins typically contain all essential amino acids and are highly bioavailable. Plant proteins require more thoughtful combination but offer additional fibre and phytonutrients. The best choice depends on your dietary preferences, ethical considerations, and overall nutrition plan. Most research shows benefits from consuming a variety of protein sources.

Older adults (65+) typically benefit from higher protein intakes to maintain muscle mass and prevent sarcopenia. Current research suggests 1.2-1.6 grams per kilogram of body weight daily, along with resistance training. Higher protein intake combined with strength work helps preserve muscle mass, maintain bone density, and support physical function as we age.

Complete proteins contain all nine essential amino acids your body cannot produce. Most animal-based proteins (meat, fish, eggs, dairy) are complete. Most plant proteins are incomplete but can be combined. For example, rice and beans together provide all essential amino acids. If you eat a variety of plant foods throughout the day, you'll naturally consume all essential amino acids even if individual sources are incomplete.

Whole foods should form the foundation of your protein intake. They provide additional nutrients, fibre, and micronutrients beyond just protein. Supplements can be convenient tools to help meet daily targets when whole food options are unavailable. They're particularly useful for post-workout nutrition or on busy days. The key is meeting your overall protein goal through whatever combination of whole foods and supplements works for your lifestyle.
