Look at this example:
"Leigh Ablett, 21, from Finedon, wants to lose 3 stone 11 pounds within 7 months - just in time for his holiday. [...]
Saturday, 24th May, 2003
Didn't loose any weight last week, but have lost a pound this week. So total of 13 pounds now. Getting there slowly. Getting hard now, but nearly at the stone mark. [...]
Expert advice by Sheila Merriman, Dietitian, St Andrew's Hospital, Northampton:
Your weight started at 18 stone 11 pounds. So you could aim to lose 26 pounds, which is almost 2 stone, in a year."
