I'm even more depressed now. I upped my goal weight loss from 20 lbs to only 15, which brought my daily calories up. BUT. I realized that it had me down for activities of 'sitting, moderate walking about' for the whole day, instead of sleeping for 8 hours. I changed that and now I'm back to only being able to eat 900 calories a day to make my goal by December 1. That seems crazy. This is only attempting to lose 1.5 lbs a week - nothing dramatic!
I think that application is actually quite irresponsible. It should not enable people to jig their goals of a certain amount of weight lost to a timetable. There should be a floor of say 1200 calories that it doesn't go below, and it should actually feed back to the user they need to change the expectations on their timetable rather than intimating that it's a good idea to lose weight more rapidly. The application should encourage people to eat a healthy amount of calories and a variety of food so you get all your nutrients each day. Jewlz's subsequent point about focusing on eating 1200-1500 calories per day is spot on, IMO.
It took practically no time for me to put on 40 pounds when I moved to the UK, and it took years to lose 58 pounds. I did this by not putting pressure on myself to achieve a particular amount of weight lost within a particular timeframe. Rather I focused on healthy eating and had a target weight in mind so that I would know when I reached my goal. But healthy eating is a lifelong commitment and even though I'm at my final goal weight now, I still eat the same as I did when I was trying to lose weight. It turned out that previous target weights were still too high, as I have a small frame and accumulate weight in different areas than most women do (I'm an apple shape).
To give you another example, a colleague of mine has cosmetic surgery booked for 18 December to fix her loose skin from having lost 10 stone after being fitted with a gastric band 3 years ago. She began binge eating after she set herself a strict goal to lose another 1.5 stone prior to her surgery date. I've tried to encourage her to focus on eating healthily and not to put a target on her weight loss, as she seems to be rebelling against this by bingeing.
I work for an IT consultancy, and am very well used to working in a project driven environment. But healthy eating is an ongoing process, not something to be managed like an IT project, as the project management approach to it can be detrimental.
