Over the past 2 years I have managed to significantly lose a lot of weight. I did this by simply reducing my calorie intake to 1200/day and light walking. I was down to my target weight (10st 4lbs) around a month ago but recently started slowly increasing my food intake . I am now having around 1400 - 1500 calories a day. The trouble is that the weight is beginning to increase slowly (1-2lb a week for the past month and I am now 10st 10lb) and I need to take action! I am still having light exercise so it can't be that I have stopped exercising. My question is why is my weight increasing when, as far as I'm concerned, 1500 cals a day is not that high really and still well below what I would expect to be typical for an adult male. I am thinking that I need to go back to my 1200 a day regime but why should I have to only have 1200 calories a day!
