I tried this for about 6 months but I also only ate 1600 calories and averaged 3lb a week loss from 260 to 180 then i switch to just a high protein only, meat, plant and dairy and bumped the calories up more. I've also did this without adding any exercise or workout to my day because I didnt want to waste my time off exercising. I feel I get plenty of exercise at work moving about. Its been a year since this and im still 180 which is dead center for my Bmi
