Greenlane Diet

 By Mizpah Matus B.Hlth.Sc(Hons)

The Greenlane diet (also known as the British Heart Foundation Diet)
is a poor fad diet that has been circulating for many years. Please note that the British Heart Foundation has nothing to do with this diet whatsoever.

The diet has circulated in the form of a one page sheet that claims you can lose 10 pounds in 3 days. The diet has been popular in the UK – but it’s exact origins are unknown.

Interestingly, the diet bears a striking resemblance to the Scarsdale diet – also written in the 1970s.

Greenlane Diet Plan

The Greenlane diet is a very low calorie diet – a typical day’s eating culminates in only 700 calories. This is a crash diet – a sudden and severe reduction in calories that results in primarily fluid loss. The diet should never be undertaken for more than 3 days, any longer and your body will immediately slow down metabolism and place you on target for yo-yo dieting (and subsequent weight gain).

The Greenlane Hospital diet contains a small selection of foods; Dry toast, fruit, tuna, ‘snax’ biscuits. Snax biscuits are a cracker made by the food brand Griffins in New Zealand indicating that this diet may have originated from this part of the world (which does have a Greenlane hospital in Auckland). However this cannot be verified.

Sample Meal Plan

This diet is not recommended


5 ‘snax’ biscuits (dry crackers)
1 slice of cheddar cheese
1 small apple


1 boiled egg
1 slice of dry toast


1 cup of tuna
1 cup of beetroot
1 cup of cauliflower
1/2 melon
1/2 cup of diet vanilla ice-cream


Black coffee/tea/water

    I don’t eat meat can I have a veggie substitute or just leave it out?

  • Stace

    Trying the diet today. Had breakfast now going on to lunch. At 700 calories a day im a little bit worried. My normal calorie range is 1200-1400 a day. One of the other girls also worked out during this diet and actually gained more weight as well as it retained her water levels as she wasnt eating enough anyway. So im wondering if anyone felt weak and helpless during this diet because although i have only had breakfast im already feeling like im STARVING and ANGRY etc. So has anyone else felt like this?

  • Nicole

    what can you eat instead of the tuna and beetroot?

    • Mary

      This combination becomes quite tasty.
      My husband and I tried this Diet scheme for 6 months and found it becamr a way of eating healthily. The weight gain was gradual with walking 3 days a week as wel. No health problems occcurred.l..Mary

    I also tried this diet, I am a insulin dependent diabetic (type2). When I started the diet I was 110kg and wanted to get down to 90kg, after 30 days on this diet I had succeeded. My method was three days on the diet and three days off and a half hour walk every day. Not only did I lose the weight I no longer need the insulin that I’ve been taking for 16 years,

My plan is to go on it on Tuesdas, Wednesdas and Thursdays – Hope it will work for me, this is for the 1st time I am goning on a diet – I was allways 58/60 kg but picked up the last 3 years – I think due to menaupause.

  • Jesika Kennedy

    Hi guys everyones comments are confusing me.Is the ‘snax’ biscuits menu the one i follow?

    • Keesha

      Hi Guys,

      It is confusing I am unsure if the diet above is the same food I will eat for all 3 days sp repeat the same thing till the 2 days is over.? or is there anywhere I can find the full 3 day plan?
      Helllp :)

      • Keesha

        i mean 3 days.

  • Deb

    I did this diet 3years ago for one month and lost 17kg’s, after one month I became agym bunny and didn’t need the diet. I lost a further 3kg’s and can eat what I want. I now weigh 47kg’s and exercise everyday for at least 1/2 hr to 1 hr. I found that water was best and herbal tea. Coffee without sugar just didn’t cut it for me as I love strong, sweet expresso. Go for it and exercise.

  • Bryz

    read about this in a book, my mum has tried it and said it is very effective. Looking forward to seeing if this works for myself.

  • Kirsty k

I’m not a dieter so this 3days only worked fantastic for me. I would keep saying only 2 more days …. only 1 more day …. now I can eat haha. Thee best fast weight loss diet I’ve known.

  • Nathan Jeune-Manning

    • SA Girl

      Hope you check in and give us an updated.

  • Kiri

    Hey all. Just want to add in here, that being from NZ myself that it did originate from here. It was designed by Greenlane Hospital for thier cardiac patients to lose weight quickly before surgery. And yes, there is a lot of fluid loss on the first round of the diet. This happens with every diet I know in the first week, thats why initial weight loss is always the highest. Just make sure you drink twice as much water whilst on it. This diet has been around for years. I did a couple of times as a teen too. The key is the low kj and if you don’t go over 8000kj a day on the other 4 days then the weight will keep coming off.

  • makz

    hey guys

    so yrs and yrs ago i did greenlane diet for 6 months once a wk and it worked!Am doin it again to get myself bck on eating smaller portions!!gd luck to all that are tring G.L!!!!

  • Barbara

    I shuold add, took 6 weeks to loose the 1okg. Also, the diet was originally 3 days with different food, to be followed by 4 days normal eating, and so forth. Thats why I think it works – get used to eating less.

  • Barbara

    I have done this, lost 10kg easily and kept it off. When I got bored I went for similar substitutes. I think one of the reasons it works is because lots of us eat too much (as well as the ‘wrong’ foods). The first week or two were hard – because I was used to eating twice as much – this diet got me into the habit of eating less, so on my 4 days off I would eat a lot less – which is why the weight stayed off when I came off the diet.

  • Nadia

    Hi there

    I can’t stand tuna, is there a good substitute that I could have and still get good results?
