I had a visit with my GP yesterday and he confirmed what I suspected
I told him I was now on a 1500 to 1800 a day calorie eating program and he said and I quote ” Wow you will lose a shit load of weight on that ! ”

He also said don’t go below 1000 calories a day which was not really relevant as I am doing 1500 to 1800 each day but worth noting for reference. Do not go below 1000 calories a day
