conversations.value: Matt's protein powder is 80% protein.  He weighs 80 kg and wants to eat 2 grams of protein per kilogram of body weight each day.  How much protein powder does he need to eat per week?
conversations.from: assistant
conversations.value: He wants to eat 80*2=160 grams of protein a day
  That means he needs 160/.8=200 grams of protein per day
  So he needs 200*7=1400 grams per week
