Protein Target Debunked

The 1g of protein per pound of body weight rule is everywhere on fitness social media. The actual research suggests less for most people. Here’s what 2026 evidence says and how to set your real target.

The actual numbers

• Sedentary adults: 0.36 g/lb (RDA) is enough to avoid deficiency. Most people exceed this without trying.
• Recreational lifters / runners: 0.6-0.8 g/lb is plenty for most goals.
• Serious lifters in surplus / deficit: 0.8-1.0 g/lb covers it. Above 1.0 has diminishing returns.
• Older adults (50+): 0.8 g/lb minimum. Higher (vs RDA) protects against sarcopenia.
• People on GLP-1s: 0.8-1.0 g/lb is genuinely important to preserve lean mass during loss.

Where the “1g/lb” came from

Bodybuilding lore from the 80s, popularized by social media. It’s not wrong — it’s just not necessary for most people, and it crowds out other dietary goals (fiber, micronutrients, calorie balance).

What to spend optimization energy on instead

• Hitting 25-40g per meal (the leucine threshold for synthesis).
• Eating protein within 2 hours of strength training.
• Spreading protein across 3-4 meals, not stacking it at dinner.
• Quality (complete amino acid profile) before quantity.
