Fat Loss Biology

The HCG diet apple day is the key to breaking through a weight loss plateau during the HCG diet protocol. You can almost expect to have at least one plateau, when weight loss simply stops for a few days. The sooner you have an apple day, the right way, the better your overall progress will be.

hcg-diet-apple-day-red-deliciousFirst of all, realize that Dr. Simeons discovered the importance of the apple day more than 50 years ago. Even though it is not new, many dieters seem to be unaware of its importance and how to use it properly.

The Basic HCG Diet Apple Day by Dr. Simeons

From his 1954 book, Pounds and Inches:

An apple-day begins at lunch and continues until just before lunch of the following day. The patients are given six large apples and are told to eat one whenever they feel the desire though six apples is the maximum allowed. During an apple-day no other food or liquids except plain water are allowed and of water they may only drink just enough to quench an uncomfortable thirst if eating an apple still leaves them thirsty. Most patients feel no need for water and are quite happy with their six apples. Needless to say, an apple-day may never be given on the day on which there is no injection. The apple-day produces a gratifying loss of weight on the following day, chiefly due to the elimination of water. This water is not regained when the patients resume their normal 500-Calorie diet at lunch, and on the following days they continue to lose weight satisfactorily.

That is all there is to it!

The Key Points

1) Eat only apples for one whole day, starting at lunch, resuming the regular HCG diet at lunch the following day.
2) Limit the number to six large apples
3) No liquids except a minimal amount of plain water, just enough to quench an uncomfortable thirst

That part about not doing an apple day on a non-injection day just refers to Dr. Simeons’ original protocol whereby injections were given six days per week with one day off. This, of course, does not apply to the use of oral forms of HCG (i.e., sublingual liquid, sublingual pellets). It probably does apply, however, to women who suspend taking HCG during their menstrual cycle.

What An Apple Day Is And What It Is Not

I just want to reiterate that the HCG diet apple day is a strategy for overcoming a normal weight loss plateau.

The reason for emphasizing that point is that I am often asked whether the apple day can be used for getting back on track after a willful interruption of the protocol. Willful interruptions include going off of the HCG for one to a few days, having one or more days off of the restricted diet to eat or drink at a wedding, a holiday dinner, a party, you name it.

The answer, basically, is NO. That is not the purpose nor the main utility of the HCG diet apple day.

I know of plenty of folks who have used the apple day several times during the protocol, to justify frequent wild swings in their eating habits. This can be effective for some people. However, for the most part, if you are not serious about staying on the protocol as it is designed, then do not expect it to be as effective as it can be.

One More Thing

An apple day, as clearly stated by Dr. Simeons, is useful for getting off of a weight loss plateau while taking HCG. It is not a strategy for weight loss between rounds of HCG or for any other non-HCG period of dieting.

All the best with your HCG diet apple day,

Dr. D

    Since I don’t eat meat is it ok to have protein shakes instead. I take 10 drops of hCG 3/day and I’m drinking protein shakes (80 calories per scoop) for lunch and dinner (total 160 calories) with 1 fruit & 1 vegetable each time. I’m drinking the required amount of water and I do drink both green tea and/or oolong tea only for breakfast and throughout the day. There is 1g of sugar and 1g of fat in the protein powder. I’m still seeing some weight loss. Please let me know if I should switch.

    I forgot-sorry! Is it alright to each a peach instead of an apple?

    Thanks again!

  3. by Dr. Dennis Clark


    Hi, Charlene: I know of no real HCG product that has you take 10 drops 3 times per day. Do you know how many IUs you are taking? The teas are fine. You can find protein powders without any sugar at all, which would be better. The bottom line is whether you are losing weight and body fat (not just weight).

    All the best,

    No peaches!

    I take the hcg drops 10 drops 3 times a day aswell and my husband and I are loosing our weight its homeopathic

    It happens. Keep up the good work!

    I did and apple day 2 days ago because I had a stall for three days. Only ate 4 apples and one sip of water for my multi vitamin. I lost a pound the next morning but gained it right back this morning – any suggestions on what I should do now. I am on day 11 of phase 2 and have not lost since day 8. Following the diet – no slips. Thanks for any help you can provide.

  8. by Anne Marie


    Correction – on day 11 of phase 2 and have not lost weight since day 6.

  9. by Dr. Dennis Clark


    It sounds as though you are doing the right things. Some people have had success doing an apple day every other day. You probably have fluid retention, and the apple day helps you get rid of some of it. That is about all that I can suggest based on the information you gave me. Good luck!

  10. by kathy


    i also take hcg 10 drops 3 times a day and am losing is this not a real product we are using we are losing weight though , and i am doing my apple a day today due to yesterday day off for special occasion and am on my 15th day and gained overnight on off 5 lbs of the 15 i have lost sunday is my day 20 i am very frustrated , any advise i only ate one day off . I will see tommorow if i had a loss on the apple a day , aafter this i am on 3 week stabalization were i am eating more , is the a guide to show me how much i increase my eating to still continue my weight loss during stabalization or isnt this possible ?

  11. by Dr. Dennis Clark


    Fluid retention can lead to tremendous weight gain in a hurry. Do the apple day every other day if necessary. I an unfamiliar with a product that requires you to take it 3 times per day. How many IUs of hCG?

  12. by carmen


    HCG1234 requires you to take 10drops 3times a day, and its homeopathic. Can I still drink greentea on a stall?

  13. by Dr. Dennis Clark


    I have no experience with homeopathic hCG and don’t recommend it.

  14. by HEATHER


    HCG1234 is a terribly fake product. it’s a “hormone free” and not to mention its mixed with “grain alcohol” which is totally not okay on the diet, and if the body is sensitive to grain makes it worse. even if you’re taking the “homepathic” it’s hormone free, it’s a glorified vitamin cocktail, and it seriously is a rip off, it doesnt actually re-set the hypothalamus. If you want a homeopathic HCG, that isnt “hormone free”, or mixed with grain alcohol try http://www.theofficialhcgdietplan.com it’s a great site, i’ve used those drops for 3 rounds and lost about 50lbs ish total. (3 20 day rounds).

    Please do research before taking “homeopathic” or “hormone free” as not all homeopathic are hormone free or vice versa, and you really dont want hormone free.

  15. by Dr. Dennis Clark


    Right on. Of course, the program that you refer to offers a product that also contains zero International Units of real hCG as well.

    I have a question. I wanna do the apple day, since it starts at lunch and ends at lunch do I eat my lunch and diner that second day of not?

  17. by Dr. Dennis Clark


    Yes. The apple day is just one day of eating.

  18. by Phil


    do you take the HCG drops during the apple day?

  19. by Dr. Dennis Clark



  20. by AJ


    Is it possibly to sub out apples for oranges?

    I have a intolerance to apples. I can have one a day but 6 is too many.

  21. by AJ


    And.. do you have lunch on the first day?

  22. by Dr. Dennis Clark


    Hi, AJ…I suspect not. Apples do some kind of voodoo magic that oranges do not do. (How’s THAT for scientific jargon?) However, you can sub. a tomato for an apple.

    All the best,

  23. by Dr. Dennis Clark


    If you are talking about an apple day during the protocol, it doesn’t matter when you eat the apples (or, in your case, tomatoes).

  24. by Jessica


    I didn’t realize that you weren’t supposed to drink fluids regularly on the apple day. I have been drinking tea and water, will I still see a drop or should I go ahead and eat dinner tonight and do the apple day tomorrow?

  25. by Dr. Dennis Clark


    Hi, Jessica: Just experiment and find out. You may get back on track with an apple day at any time.

    All the best,

  26. by sallyrenee


    I did the Apple day last week an didn’t know I couldn’t drink, I thought I had to drink extra actually, so I drank all day….in the morning, I had lost 3 lbs

  27. by Dr. Dennis Clark


    Hi, Sallyrenee:

    Nice going!

    All the best,

  28. by MrsSunshine


    Has anyone heard of not losing weight when they drank a lot of water on the apple day?

  29. by Connie


    I have been talking HCG for 22 days and I had to go away for 5 days and I tried to stick as close to plan as I possibly could but I had a few drinks and only had a few meals that were not allowed. I came back and only gained 2 lbs but then the next day was back at where I started. Now its been a week and I have only dropped 1 lb. I have only lost 7.2 lbs all together. I follow everything buy prodocol. What do I do?

  30. by Samantha


    I am taking the premium hcg drops and take tow drops 3 times a day, dont really get hungry but my stomach growls at times, this is only my second day on the diet thought and I have lost 1 lb is that good. And how much weight should I lose a day to know if the drops are the real thing.

  31. by Dr. Dennis Clark



  32. by Dr. Dennis Clark


    Connie…this would be a good time to do an apple day to get back on track.

  33. by Dr. Dennis Clark


    Samantha…your product is most likely a homeopathic one, so your results will be from starvation, not hormone-driven fat loss.

  34. by LVBrasil


    The day you start the apple day at noon do you skip your breakfast and mid-morning snack or have your normal HCG breakfast and mid-morning snack?

  35. by Dr. Dennis Clark


    Yes, have only apples and very little water or liquid intake.

  36. by anna


    I’m using HCG Triumph. I started on 2 of august and I have lost 6 pounds. I dont feel hungry at all but I eat my greens and some protein at dinner. I drink at least 5
    16oz of water a day and very mild exercise…walk every other day for 30 minutes. But i notice that for two days I weight the same so Im doing the apple day today and see how it goes.

  37. by Gina


    On the apple day can I use a variety of apples?

  38. by Helena


    Im doin the “Hcg solution dietary supplement” drops and I’m on day 17 and have lost 15 pounds are my drops the right ones or are they fake?

  39. by Mai Linn


    Hi Dr. Clark,
    Is there a specific brand of HCG drops that you would reccomend. What should we look for and where? They have so many products out there and it’s so confusing. I also use the drops @ 10 drops 3x per day, but I thought that,they were the real HCG drops. Yes, I am still losing weight, but I worry about not getting the full effect such as resetting my hypothalamus. Thanks for your help.

    Hi, I have a question…I stopped the shots for the 2 heaviest days of my menstruation but I noticed I gained a few ounces even though I did 30 minutes of exercise on the treadmill but I want to resume on the shots again tomorrow. Is it recommended I do an apple day to get back on track or how does this usually work? What do you recommend?

  41. by cm


    say i start an apple day tomorrow, i eat 6 apples from lunch tonorrow to lunch the next day….on the second day do i eat dinner or i dont eat anything until the following day?

  42. by Dr. Dennis Clark


    Hi, Stephanie…It might be best to just resume the protocol. A few extra ounces are no doubt just excess fluid.

    All the best,

  43. by Dr. Dennis Clark


    CM…apples and little water during the apple day, then resume the protocol the next day.


  44. by cm


    Thank you for answering so quickly. Im still a little confused. Is the apple day just day one? Because it lasts over two days. So i dont eat until the third day? Or after the apple day lasts 24 hours i then end apple day at noon and eat dinner? So today it wendesday. Im starting apple day today and ill end it thursday at noon. Do i eat dinner thursday or wait until friday to eat?

  45. by Theodora

  46. by Lola


    I am taking Easy Hcg. It is a homepathic product and I take 10 drops thrice a day. I am only on day 5 but I have only lost 2 pounds. Is this a good brand? Where do you recommend I buy from Dr. Clark? I have only two months to lose as much weight as possible. Please help!!

  47. by Sindy Towne

  49. by Viviana


    Can i do an apple day during my menstrual period? I lost a total of 7lbs and since last saturday i stopped loosing weight today i gained half a pound. I’m still on my period. Can i do an apple day?

  50. by Jessica



    I’m on days 5 hcg injections. I lost 7 pounds after gorging for two days. Overnight! Since then I have lost nothing.
    I’m doin the Apple day today.
    I would like to know how many apples I should eat one 1200 calories as I workout.
    I lift for 50 min M-F and 20 minutes of HIIT sprints or biking three days a week.
    Should I be eating less calories as the rest of my day I’m not so active? And how many apples on a 1200 calorie diet?
    I’m taking 125 ius each morning.

    Thank you!

  51. by Dr. Dennis Clark


    Hi, Jessica…I am not clear what protocol you are following. HCG injections with the Simeons protocol are incompatible with 1200 Calories per day.

    All the best,
