HCG: The Most Taboo Diet Ever

This post is pretty personal for me, as I’m sure weight loss is for many of you. I’ve been slowly gaining weight since I was 18. It creeps up on you and all of a sudden you feel puffy, bloated and blah. I decided to do something about it when I didn’t like smiling in photos anymore because I felt like my face was too “round”.  My friend did the hCG diet and lost 20 pounds in 40 days and I knew I had to try it.

*For the record, I don’t consider myself fat but I do have some fat I can lose. 

HCG diet and why it's considered taboo for weight loss

Before I get into the diet, let me tell you a little about my weight loss history…

When I was in High School I joined a workout/ weight loss group with my mom. We would do these group workouts 3x a week and follow a very specific diet. It was 6 weeks long and we were both very committed. My mom lost 15 lbs and I gained 5.

When I was in college I went on a 6-week backpacking trip with my mom and sister. We walked 500 miles (heard of the Camino de Santiago? That’s what we did!). They both lost 20 pounds and I gained 12.

After college, I signed up to run the Disney half marathon with my girlfriend. I hate running. I really just wanted to lose some weight from training. Nope, I gained weight…again.


I tried working out regularly and really watching my diet when I was 26. I would go to the gym with my coworker 5 days a week- we did weight training, cardio, and classes. I definitely toned up but my weight stayed the same. I know muscle weighs more than fat… yeah yeah yeah. But still, when you’re working HARD at something it’s nice to see the numbers on the scale change. 

A poor diet will lead to weight gain, but HCG can help you lose the wieght!

So, maybe that’s another reason I pretty much stopped trying. I figured “Hey, I eat healthy most of the time and have decent portion control, I’m healthy- I’ll be fine.”  

NOT FINE. Insecure and uncomfortable is just not the way to live.

So in July 2017, I started the hCG diet. This also was right before my wedding (which, we planned in 5 weeks so the timing was perfect!). I got the shots from a local medical spa and had to do check ins with them every 2 weeks. 

Guys… I lost 18 pounds! This was the first time I’ve EVER successfully lost weight! I felt amazing and was so happy with the results. Don’t get me wrong. This diet is HARD. It takes a lot of self-discipline, you feel “off” many days, and you’re hangry. But seeing the numbers on the scale go down so quickly, and watching my body transform makes it SO worth it.

I completed the diet in August and I’ve gained 6 pounds back but my measurements were almost the same as when I finished.  I’m doing the diet again because I would like to get down another 15 pounds or so.

What is the HCG Diet? Brace Yourself: It Sounds CRAZY.

HCG or Human Chorionic Gonadotropin was discovered by Dr. Simeons while he working with severely malnourished pregnant women in India. He noticed that despite their weight, they were somehow still giving birth to full-sized, healthy babies. That’s when he learned about HCG. HCG is a hormone that is naturally produced by women during pregnancy it acts as a backup mechanism that allows women to nourish their unborn even if they are consuming a low amount of calories.  HCG draws fat from the body’s secondary fat reserves to feed the developing fetus so it can grow at a normal rate.

How Does HCG Affect Someone That Isn’t Pregnant?

Everybody retains fat as a survival mechanism, no matter how much diet or exercise the person does, it will not release these reserves. 

HCG triggers the body to release this secondary fat reserve. Dr. Simeons first tested in patients without any dietary restrictions. He found that the shape of the patients’ bodies were completely transformed even though the patients did not lose weight.

He tested again and put the patients on a very low-calorie diet. This enabled the abnormal fat to be released and caused the body to take from its own fat and use it as fuel.

While you are on hCG, your body releases a between of 1200-4000 calories from your secondary fat reserves to be used for fuel. So even though you are only eating 500 calories a day, you don’t feel very hungry. Crazy, right?

If you were to only eat 500 calories a day without the HCG hormone your body would go into starvation mode and begin to eat your muscle, but with the hormone, your body eats its own stored fat. Make sense?

So What Should You Expect from the HCG Diet?

I love HCG because it is basically like hitting the reset button on your metabolism and you will typically lose between ½ to 1 pound a day!

The duration of the diet depends on how much weight you want to lose.

~If you want to lose 15 pounds or less you do the program for 21 days.

~If you want to lose more than 15 pounds or more you do the program for 40 days.

The maximum weight loss per hCG program is 34 lbs. The treatment is stopped when either 34 lbs. have been lost or 40 injections have been given.

There Are 3 Phases of the HCG Diet

Phase 1- Loading: The first 2-3 days you take your shot of hCG in the morning. You need to eat as much high calorie/ high-fat foods as possible to prepare your body for the diet. This is really important because it takes your body time to adjust to the hormone and it takes this long to start pulling secondary fat. If you don’t do this you will feel like you are starving the first week.

Phase 1 is obviously my favorite part of the HCG diet ????


Phase 2: Weight loss- Continue taking HCG and eat only 500 calories a day. The 500 calories must come from very specific foods.

No fats, sugars, carbs, alcohol…etc. Below is the list of food you’re allowed to eat while on the diet.

Drinks- You must drink a gallon of water a day. You can have any amount of tea or coffee. You also can have 1 TBSP of non-fat milk.

Lean Protein- You must have two servings of 3.5 ounces. You need to mix up the protein each day. So if you have fish for lunch you can’t have it again for dinner.

Vegetables- You must have two cups of vegetables a day. The diet claims you can’t mix veggies (so only lettuce, no lettuce with tomato). In my opinion, some rules are made to be broken. Hah.

Starch- Optional 1 Grissini cracker a day. Yes, you read that right. But I promise it’s not that bad.

Fruit- 2 servings a day. Strawberries are preferred because they have the lowest amount of carbohydrates. You can also have oranges, 1/2 grapefruit or an apple. 

Fortunately, you are allowed to have spices and stevia. Just make sure the spices don’t contain sugar.

The needle is SO tiny you barely feel anything!


Phase 3: The first 3 days of Phase 3 you continue to eat a 500 calorie diet but stop taking the shots.  You gradually increase food intake but avoid sugar and starch for 3 more weeks.

Last time I did the HCG diet I was so terrified of phase 3. Phase 2 was easy because there was a strict list to follow but phase 3 is when you really test your willpower. This phase is SO important because this is when your body is the most sensitive and is likely to gain the weight you lost back.

I go through phases where I don’t feel like cooking at all. With the HCG diet it’s a requirement. So when the diet is complete my palette has been reset to eating home-cooked meals without a lot of butter or oil. Or just to make better choices when eating out. It makes it easy to transition back into regular eating while maintaining a healthier mindset.

As much as HCG sounds like the miracle diet, it’s still difficult. I miss food, especially carbs and cheese. I am currently questioning my sanity while doing this again. I’m also counting the days until my 26 days are up. But, I just keep reminding myself that the end result is so rewarding! 

What diets have you tried? Let me know in the comments below!


Love Lauren

  1. Your dedication to this is amazing. I didn’t realize you gained weight on the Camino! That sucks! So question… if you did a pregnancy test during the shot portion of this diet, would it be a false positive?

  2. I’m on day 3 loading. I’m using the drops instead of the injections. Round 2 here we go! This diet is difficult but it does work well! Let’s encourage each other!!

  3. Wow! This seems like such a hard diet to do…great job for persisting Lauren! You look FAB!!!

  4. HCG (human chorionic gonadotropin) is a hormone that is made by the developing embryo after conception and later by the placenta. It is most commonly used to increase testosterone levels in men and in extremely high doses to cause ovulation in women.

  5. I’m so blue. I tried the 21 day and fell off at Day 14. I went from 168 to 179.4. I cheated while taking the shots and told myself every day would be different. I’m considering doing the 40 day if I can afford it and get my mindset right again. I feel so lost and gross and I hate that I have such body issues.

    1. Hi Candice,
      I’m sorry you are struggling with HCG. This is definitely one of the hardest diets to stick to. I found that even when I “Cheated” I still ate clean foods which helped me with the guilt.Don’t feel gross, just know forgive yourself and do better next time! You got this!
      xx- Lauren

  6. Its like you read my mind! You appear to know a lot about this, like you wrote the book in it or something. I think that you could do with a few pics to drive the message home a bit, but instead of that, this is excellent blog. A great read. I’ll certainly be back.

  7. I did the hcg diet about 10 years ago and am thinking of doing it again. I’m nervous though because I was so disciplined then, not so much now.

    1. It was SO MUCH HARDER the second time around and I only did it 6 months later! You might actually think it’s ok because they came out with some great alternatives with 0 calories in the last few years.

  8. Obvi, you look amazing! Any pre-hcg photos? I def have more than just 20 to lose and in going a full 40 days, but this is super inspiring. I’m on day 5 of phase 2. And, I, too, am nervous about phase 3… Any additional tips? Is it basically Paleo + cheese for 3 weeks?

    Thanks for the post. 🙂

  9. I’m looking to start but am nervous that it will mess up my hormones. Also, once you’re finished, I’m afraid that I will gain the weight back. I do eat pretty clean and struggle to lose any weight. What’s it like when you finish the 40 days?

  10. Hi Lauren – I have just started HCG drops, been very strict (except have mixed veges), I have done this diet before and it really works but in my first week and have gained (300gm) I know that’s a small amount but any advice??

    1. Hey Kelly,
      Ooh good for you! The HCG is no joke! I’m not sure what 300gm is? When I did the calculations it looked like under 1 pound? Your body may be holding onto anything and everything because it’s in shock?

  11. Hi Lauren, thank you for writing this out. I am going to be starting my injections this week, I cannot wait! I have one question for you… did you deal with excess skin? That is one thing I am terrified about when doing this diet. I have 100lbs to loose and I dont want to have excess skin. Is it safe to work out whole on the diet? What was your experience?

  12. I am starting this diet next week, I have done lots of research and really the only thing that was holding me off was having to inject myself. Do you have any suggestions to doing this?

  13. This was very helpful. This is my loading day 2. Yes, total newbie. I was at first a little shocked with the cost of the program I am on, but your honesty about the program and your results are an inspiration.
