Help with conversions for family

To the program dietitian please. I am starting week 2 today. One of the questions presented was concerning family members. The said to contact the dietitian and they would help with the conversions for any family member. They said to include weight, height, gender and activity level. So I am asking for my husband. He is 59 years old, 6ft tall, 210 lbs, and activity is pretty low right now. He’s had Lyme Disease for 3 years, but is trying to do 2 miles a day on the bike. Hoping as he gets stronger he can do more..soon! Thank you for your help.
