If you started the new year with all good intentions to lose weight, but are already flagging, let your smartphone shame you into shedding the pounds.

Carrot Hunger is the latest in a line of 'sadistic' apps designed to motivate people to get fit and lose weight by being judged and 'shouted at'. 

The Hunger app lets users count their daily calorie intake, tells them how much exercise they'd need to do to burn it off, and can even tell people to step away from their fridge or cookie jar.

Carrot Hunger is the follow-up to Carrot Fit, and both were created by Pennsylvania developer Brian Mueller. 

His range of apps is designed to 'threaten, intimidate and ridicule' users into losing weight. 

Users add food to their diary either by searching the database, or scanning the bar code.

For each food item entered, the app converts the calories into easy-to-understand terms. 

For example, the calories in a slice of pizza translate into a 90-minute walk. 

The app also tells someone how many miles they would need to run to burn off certain foods. 

If a user eats too many calories, or starts putting on weight, their avatar 'blimps' up, and the user is 'punished' into getting back on track. 

For example, Carrot will show fullscreen adverts, or send tweets about their weight gain.

And, when used with an iBeacon inside the fridge, for example, Carrot knows when their reaching for food.

It then reminds users to log any food they've taken out of the fridge, or will sound a loud alarm if they're nearing their calorie limit.

With Carrot Fit, released last year, Users input their weight on a daily basis, and receive judgement from the 'Carrot overlord' (pictured). Equally, if they lose weight, Carrot offers encouragement

Carrot Fit was released last year.

Users input their weight on a daily basis, and receive judgement from the 'Carrot overlord', yet equally, if they lose weight, Carrot offers encouragement.

As well as encouragement, people who lose weight will be given rewards such as workout tips and advice.

According to the app's description: 'Carrot is a sadistic AI construct with one simple goal: to transform your flabby carcass into a Grade A specimen of the human race.

'She will do whatever it takes - including threatening, inspiring, ridiculing, and bribing you - to make this happen. You will lose weight - or else.'

As a user tracks their weight, Carrot Fit monitors their BMI and updates them on their progress.

All weight loss is tracked on a graph that can be shared with friends and at each weigh-in, Carrot will let the user know how much they've lost and the difference compared to the previous weigh-in. 

App that bullies you into losing weight

If the user gains weight, the app turns red (pictured left) but if they lose weight, it turns green (right)

Users can set goal weights, share their progress with friends and set reminder to weigh themselves.

Mr Mueller said he didn't create Carrot Fit to make people feel bad, instead he wanted to make 'weight loss entertaining and funny.'

The Hunger app is free, but the Fit app costs £2.49 in the UK and $2.99 on the US store. 

Mueller has previously created similar apps, called Carrot To-Do and Carrot Alarm, that both use an avatar to encourage users to be more productive, or active.
