Why Protein Matters

Protein is a vital macronutrient that plays a key role in nearly every function of the body. Most people associate it with muscle repair, but it does much more than that.

• Builds and repairs muscle tissue after workouts or injury
• Keeps you fuller for longer, reducing overeating and sugar cravings
• Supports hormone production, immune function, and neurotransmitter health
• Stabilises blood sugar, helping prevent energy crashes throughout the day

How Much Protein Do You Really Need?

The amount of protein you need depends on your body weight, goals, and activity levels, but most people aren’t getting enough.

General maintenance: ~1.2–1.6g protein per kg of body weight

Active/training individuals: ~1.6–2.2g protein per kg

Fat loss goals: Higher protein can preserve muscle mass while reducing calories

It’s also important to spread protein intake evenly throughout the day for optimal absorption—don’t just stack it all at dinner.

Pitfalls to Avoid in High-Protein Diets

It’s easy to go high-protein in the wrong way. Common mistakes include:

Relying too much on protein powders and processed bars full of sweeteners and additives

Neglecting fibre and micronutrients - important for digestion and satiety

Forgetting hydration - your kidneys need water to process protein efficiently

Ignoring meal timing - skipping breakfast, then overloading at night
