I’m 4’9 OP and will only lose weight on 1000 calories or less at my age (41) eating the recommended 1,400 calories to maintain feels like I’m feasting.
A lot depends on height and exercise, I’m active but have learned to restrict calories all my life and exercise or I gain weight quickly.
I’m 9 stone 11 now and look and feel overweight, I was always between 8 and 9 stone until my 40’s but I eat the same and have gained weight and I hate it.
A lot of people commenting won’t realise how much the height difference matters.
As long as you do it in a healthy way then it’s ok, I eat plenty and I find 1000 calories to be sufficient. I do miss wine, bread, cheese and even something as simple as hummus though!
