If I eat less than 800 kcals, plus do over 10,000 steps per day plus a gym workout, I loose 3lb per week. I generally end up binge eating after a couple of weeks as this is not healthy or sustainable.
If I eat 1200 kcals plus walk 10,000 steps I loose about 1lb per week
On 1500 kcals plus activity I loose about 0.5lb per week, but I've found this way of dieting way more sustainable and I can stick with it for months and the weight stays off when I go back to eating normally. if I want to and on that amount, I can include treats as part of my diet, so although I'm always consciously aware that I have to control myself, I don't feel so deprived.
I have a long history of disordered eating. I'd fast and deprive myself only to send up binging later down the line, so I always fluctuated and lost and gained the same 10lb or so. Took a long while to realise that if I want to really change my body (and not impact my mental health) slow and steady wins the race.
I just eat intuitively now, although I'm breastfeeding at the moment so intuitive eating = eating everything in sight, but I'm maintaining my current weight.
