Question 1

How much protein do I need per day?

Accepted Answer

Most healthy adults need 0.8-1.0 g of protein per kg of body weight per day for general health. If you exercise regularly or have specific goals like muscle gain or fat loss, you likely need more — typically 1.2-2.2 g/kg depending on your goals and activity level.

Question 2

Is 1 gram of protein per pound of body weight too much?

Accepted Answer

For most healthy people, 1 g per pound (2.2 g/kg) is safe and can be beneficial for muscle gain when combined with resistance training. However, this is at the upper end of evidence-based recommendations. Most people see excellent results at 0.7-1.0 g per pound (1.6-2.2 g/kg). People with kidney disease should consult their doctor before high-protein diets.

Question 3

How much protein per meal is ideal?

Accepted Answer

Research suggests 20-40 g of protein per meal effectively stimulates muscle protein synthesis. Spreading your total daily protein across 3-5 meals helps maximize absorption and utilization. Very large single doses (over 40-50 g) can still be used by the body, but distributing intake is generally more practical.

Question 4

Can you eat too much protein?

Accepted Answer

For most healthy people, protein intakes up to 2.2 g/kg are well-tolerated and safe. Very high intakes (above 3-4 g/kg) have not shown additional benefits for muscle growth and may be unnecessary. People with existing kidney disease should follow their doctor's advice on protein limits.

Question 5

Should I use total body weight or lean body mass to calculate protein?

Accepted Answer

Using total body weight is simpler and works well for most people. If you have a higher body fat percentage (above 30%), using lean body mass or an adjusted body weight can give a more accurate target to avoid over-estimating needs. Our calculator adjusts for this when you enter your body fat percentage.

Question 6

Do I need more protein as I get older?

Accepted Answer

Yes. Adults over 65 generally benefit from higher protein intakes of 1.0-1.2 g/kg per day (or more) to help counteract age-related muscle loss (sarcopenia). Combined with resistance exercise, adequate protein helps maintain strength, mobility, and independence.

Goal	Range (g/kg/day)	Range (g/lb/day)
General Health	0.8 – 1.2 g/kg	0.36 – 0.55 g/lb
Muscle Gain	1.6 – 2.2 g/kg	0.73 – 1.0 g/lb
Weight Loss	1.2 – 2.0 g/kg	0.55 – 0.91 g/lb
Body Recomposition	1.4 – 2.2 g/kg	0.64 – 1.0 g/lb
Older Adults (65+)	1.0 – 1.2+ g/kg	0.45 – 0.55+ g/lb
