Protein gets a lot of airtime in nutrition conversations—and for good reason. It’s not about chasing gym-bro macros or living on chicken and shakes. Getting enough protein is one of the most important (and often overlooked) foundations of good health, especially as we move through midlife.
So… why does protein matter, and how much do we actually need?
Protein needs increase with activity level, age, and health goals. The standard minimum (0.8 g/kg) prevents deficiency—but it’s often not enough for strength, metabolic health, or midlife body composition.
| Activity Level | Protein Target |
|---|---|
| Sedentary / low activity | 1.0–1.2 g/kg/day |
| Lightly active (walking, Pilates, yoga, 1–3x/week exercise) | 1.2–1.4 g/kg/day |
| Moderately active (regular cardio or strength training 3–5x/week) | 1.4–1.6 g/kg/day |
| Highly active (intense training, heavy lifting, endurance sport) | 1.6–2.0 g/kg/day |
| Fat loss with muscle preservation | 1.6–2.0 g/kg/day |
| Older adults (midlife+) | ≥1.2–1.6 g/kg/day |
How to apply this in real life
- Calculate your body weight in kg
- Choose the range that fits your activity level
- Aim for the middle of the range, not the extreme
- Distribute protein across the day
- ~25–35 g per meal for most adults
- Include protein at breakfast (this is where most people fall short)
Example
A 70 kg person who strength trains 3–4x/week:
- 70 × 1.5 = ~105 g protein/day
- Split over 3 meals → ~30–35 g per meal
What protein actually does in the body
Protein isn’t just about muscle (although that’s a big part of it). Protein is essential for:
- Maintaining muscle mass and strength
We naturally lose muscle as we age. Adequate protein helps slow this process and supports everyday function—lifting groceries, climbing stairs, staying active. - Metabolism and energy balance
Muscle tissue is metabolically active. Preserving it helps support metabolic health over time. - Satiety and appetite regulation
Protein helps you feel full and satisfied after meals, which can reduce constant snacking and energy crashes. - Blood sugar stability
Including protein with meals slows digestion and can help reduce large blood glucose spikes. - Repair and recovery
From exercise to illness to daily wear and tear, protein provides the building blocks your body uses to repair itself.
