For example:

  • 180g – 220g is 70g with something else, someone still needing 70g can eat something which has some grams of protein then it’s not a huge jump to add more

  • Resistance training
  • Recovery
  • Adequate calories
  • Sleep

Person Recommended Daily Protein
Average healthy adult Around 0.8 g per kg body weight
Recreational exercisers 1.0–1.4 g/kg
Strength training 1.4–2.0 g/kg
Older adults Often 1.0–1.2 g/kg (depending on health advice)
