Since January 1st 2012 I have been depending on the aid of MyFitnessPal to help me lose weight, by calorie counting. Some may see this as an unhealthy way to lose weight, but it works for me and I can keep it up. I use the MFP app on my iPhone 4S as that way I can keep track of all my foods/drinks on the go.
You enter in your details, such as height, weight, age, gender, etc. and how active you are in your everyday life and it then calculates approx. how many calories you need to consume each day in order to lose weight. I am calculated to eat 1200 kcal per day and for the first year-ish that really worked for me. But after starting the gym earlier this year (that I am currently not doing, due to health reasons, but I'd like to go back soon), I have had to up my calorie intake to 1400 kcal per day, as 1200 just wasn't enough and it was making me ill.
Although this way of losing weight works, it can become seriously obsessive. Since starting using the app I have only ever missed about 20-30ish days (mainly my holidays abroad). I calorie count everything. My good days, my average days and my seriously bad, binge-eating days. I weigh myself once a week too to keep track of my progress (naked, every Friday morning and I place the scales on the same tile in the same room each time - I get paranoid if it's in any other place in case it's slightly inaccurate).
I'd recommend this to anyone trying to lose weight. But I wouldn't try it if you know you aren't going to commit 110% to counting all f your calories (even that one-off, sneaky chocolate biscuit you have with your cuppa). You must log everything in order for this calorie counting diet to work its magic.
I personally LOVE this app, and even though I sometimes have my off-days and bingey-days, I don't think I'm going to stop counting my calories for a looong while. I actually enjoy it and love seeing results!
If any of you have any views, success stories or experiences using this app, I'd love to hear them! :)
