Enjoying the app but...

I was getting on well with the nhs weight loss app, and don’t mind the two step process to get to the calorie checker but.... why is it changing my maximum calorie target. I started off at the top figure and have been losing weight regularly and painlessly on this, but last week, possibly after an update, I found the target had been reset to the minimum amount. Shortly after this the maximum figure has been reset to a lower amount so that if I keep to my original target I’m about 50 odd calories over and get a pink display. It’s very disappointing that this has happened on the eighth week. I think it should stay at the original amount until the end of the 12 week course and then, if you wish to go down you can start a new 12 week course.

Edit: I finished my first 12 weeks with a respectable 9lbs loss which was a t a rate I was happy with and didn’t stress me too much. I was happier with the app before the recent update which added badges etc, but have generally found it useful. I was disappointed however to find when I committed to a further 12 weeks that I’ve lost all my previous weight loss details. It would have helped my commitment to be able to refer back to them. Also when I put in my final weight and waist stats on Sunday morning I was locked out of the rest of the day and couldn’t fill in my daily consumption. I had to reset the app and start again on Sunday meaning my first week had only one day’s totals in it.

Very effective, effortless weight loss

This is my 2nd 12 week program. I lost 9 pounds and gained 1 in the week after finishing the 1st. It takes less than 10 seconds to work out what you’ve eaten and add in the calories, so for around 40 seconds of effort per day you can keep track of your intake. I naturally find myself eating smaller portions, eating whole fruit rather or have a smaller fruit juice, a smaller amount of chocolate (family bars are not more economical) or cheese - grated, not sliced, and not with every meal). I can bypass the treats that I’d previously justified quite effortlessly (it’s a bargain, I’ll space them out over the week (yeah right)). I wouldn’t touch a Danish pastry now. You can push the limits at the weekends but compensate during the week. It’s like having a bank account, the weekly data’s there, so you can adjust you intake and expenditure (activity) accordingly, responsibly, without having to think back to how you might have gained another pound. I’m happy with a low and consistent loss through making better choices. Start on the day of the week that you’re at your lightest if you can as that’s more motivating. Good luck!

In some ways a bit too simple

The app is fine if a little on the basic side. I like that is doesn’t ask you to other think weight-loss as a lot of the more complicated apps do. My one issue is that the app has an over simplistic and slightly dangerous mindset of ‘weight loss = good, weight gain = bad’. For the first 3 weeks I was using the app I lost weight through healthy eating and exercise which the app responded well to. However, when I gained muscle, the app merely saw this as a bad thing when really it’s just an indicator that I’ve formed a healthy diet + exercise routine.

The app gives you an option each day to input any exercise you’ve done and the time you did it for but it has no bearing on the overall experience whatsoever, as the data is not taken into account at all so the feature might as well not be there. If it took time spent on exercise during the week into account, I think the app would understand that I’m not gaining ‘unhealthy’ weight (fat) but ‘healthy’ weight (muscle), and creating a much healthier lifestyle for myself which is ultimately supposed to be the whole purpose of the app. I think this is especially important as this app is attached to the NHS. No doctor would view a patient gaining muscle as a result of physical exercise and good diet as a bad thing- in fact it would be the exact opposite- so it’s a big flaw in the app that it’s oversimplified design causes it to do exactly that.
