British Heart Foundation Diet

The British Heart Foundation Dietis 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 its exact origins are unknown.

British Heart Foundation Diet Plan

This diet is very low in calories and not recommended

Breakfast

5 ‘snax’ biscuits (dry crackers)
1 slice of cheddar cheese
1 small apple
1 cup black tea/coffee/water

Lunch

1 boiled egg
1 slice of dry toast
1 cup black tea/coffee/water

Dinner

1 cup of tuna
1 cup of beetroot
1 cup of cauliflower
1/2 melon
1/2 cup of diet vanilla ice-cream
1 cup black tea/coffee/water

The British Heart Foundation diet is a very low calorie diet (approx. 700 calories per day), and is often only used for a few days. It is unsustainable. The meal plan should not be undertaken for any length of time without medical supervision.

Very low calorie diets like The British Heart Foundation Diet do not lead to lasting weight loss and can be dangerous due to the low calories recommended. Any weight loss will likely rebound when normal eating is resumed.

Instead we recommend that dieters look for weight loss plans that encourage slow and steady weight loss, while emphasizing nutritious foods that fuel the body with the nutrients in needs and that promote overall good health.

The British Heart Foundation diet does not meet these guidelines.

    Hi! Everytime I have done this it has worked really well. The initial couple of times I had lost 10 pounds exactly. If you do it very often the amount you lose may be slightly lower but still significant. It is also very important to drink plenty of water (10 glasses per day). This of course adds to the diets success, flushes out the toxins produced and makes sure you do not dehydrate. Also in order for this diet to work you have to follow it exaclty which means no food substitution. I have actually spoke personally to a member of staff belonging to the British Heart Foundation in regards to this diet and without going into alot of longwinded detail, the way in which the diet works, is that it causes a chemical breakdown of fat in the body. The combination of the specific foods in the diet causes this to happen that’s why it is so important to stick to it perfectly.
    It is not the easiest of diets but it is safe as long as it is not done continously and the results are good.

    I did this last week and lost 5 lbs and didn’t feel hungry at all. am on it again this week but cutting out the ice cream because I have a cholestrol condition so we will see. This is much better than the previous diets which were all protein and no fruit or veg. Try it for 3 days you will be suprised.

    From the review: the diet provides 700 calories. Let’s say you would normally burn 2000 calories per day. 2000 – 700 = 1300 over 3 days = 3900.

    There are 3500 calories in a pound of fat. So total fat loss over the 3 days will be around a pound.

    Weight loss greater than this is likely to be your body losing a combination of water and glycogen.

    The heavier you are, the more water and glycogen your body will contain and therefore, the greater the initial weight loss at the beginning of *any* diet. When you begin eating normally, your body will replensih these and therefore that weight will go back onto your body.

    It’s not about weight loss, it’s about *fat* loss. It’s important to know the difference.

    The diet I have is a 3 day diet and there are strict instructions not to substitute any of the foods in it.

    Although its a low cal diet – i think it works on the basis of the foods containing a lot of water…so substituting chicken for tuna, or some other fruit for melon will not work.

    If you are going to substitute…then reduce the quantity. 4oz chicken is not equal to 4oz of tuna.

    We have just weighed ourselves, on this morning after three full days strictly following the diet. Results: My wife lost a total of 2½lbs. From 11.10½ down to 11:8lbs. (Strangely she did not lose any weight for her efforst on day 3, but her personal trainer said it is quite likely she will see further weight loss tomorrow) She is, nevertheless, very pleased with even this weight loss. I have come down from 17:3lbs to 16:10¾lbs. This represents a total loss of weight for the three days of 6¼lbs. Not bad. Not as great as the advertised 10lbs, but a lot more than any other diet ever achieved in such a short time. Lastly, we lost weight without any discomfort whatsoever – quite enjoyable really. So, reader, my recommendation is – go for it!

    After Day 2. Somewhat disappointing results today, I’m afraid. Wife lost only ½lb and I lost 1¾lbs. I am much fatter than she is so presumably my rate of loss is correspondingly higher. Anyway, O reader, do not lose interest yet. Day two was a Sunday and the only exercise I had was getting on and off the scales. Besides Day two, I would like to believe, is where the body is looking for hidden reserves. I am feeling very light and I am sure tomorrow will produce wonderful results. Having already lost 4½lbs in just two days I am still most content. Most importantly, neither wifey nor I are suffering any pangs of hunger (so long as we do not dwell on the ffod ads which pop up on TV). Final report tomorrow, Day 3. Bye for now.

    After Day 1, my wife an I weighed ourselves. She has lost 2lbs and I have lost 3lbs. So far it is working and no real pangs of hunger yet. And no exercise!! This could be the one! Further update tomorrow.

    This morning my wife and I began this diet. I shall be incredibly strict over these three days so that i can report accurately my progress on this site day by day. I celebrated my decision to embark on this diet yesterday by eating too much so my weight loss today will probably be reduced by yesterday’s excess. My wife was more sensible so it will be an interesting comparison. This morning I weighed a disgraceful 17 stones 3lbs. I’ll be in touch tomorrow. Bye for now.

    I tried the diet last year for 8 weeks of 3 days at a time and lost weight noticable. I continued to lose weight after stopping. I am now starting to gain weight and will be going back on the diet again. I recommend it. By the way I enjoyed the food and after the second 3 day diet I did not feel hunger pains.

    I did a similar diet, high in protein for about two months and suffered heart palpitations for a year afterwards. This outcome may or may not be linked to the diet, but I would advise caution to everybody.

    I’ve tried loads of low calorie diets before- lower than this- and now i have gone back to healthy eating and I’m a healthy weight, not overweight. So does anyone know if this diet will actually result in me losing any weight? As my body is already used to low calorie diets!

    I’ve done the diet before, and managed to lose 7 lbs in 3 days. Myself and my daughter are trying it again and although I’ve been much stricter this time, i seem to have only lost a couple of pounds in two days, whereas my daughter has managed to lose 5, and she has not been so rigorous with the diet. Its a good way to kick start your healthy eating program. What have you got to lose?

    I have done this diet quite a few times and find it works well. Obviously if you are not very overweight you will not lose loads of weight but I usually manage about 4 lbs in the 3 days. Gonna do it again next week as wanting to lose some more before my holiday! Only trouble is I dread the last meal every time. The version I have is different meals each day not the same as above???

    This diet works for me too – every time. It is only three days and if you eat sensibly the rest of the week it does no harm. As a one off three day plan it is an excellent way to kick start or reinvigorate a long term (and therefore much slower weight loss) healthy eating plan.
