What is the correct K/Cal figure. Advice given on NHS site suggests 1700 - 2200 is range for 69 Male of 166.4cm whose to maintain and achieve a 24%/68Kg level. Does that figure mean to maintain that calorie intake. I have lost 10kg since 6th Jan, but the last 4 weeks have seen a plateau, despite a current average K/Cal of 800 to 1100 per day, and a average daily brisk walk of at least 5 miles on top of all other activity. Am I still eating too much..... it is very confusing.
