Founded by David Zinczenko in 2012, the 8-hour diet is based around the idea of intermittent fasting for 16-hours, and letting your body eat meals for the remaining 8 hours of a day. There are absolutely no food restrictions on this “diet” but if you gorge on junk food you must immediately start fasting for the next 16 hours. This diet already does not support healthy habits eating, nor does it promote exercise of any kind. I already see terrible habits forming which can lead down dangerous paths of nutritious related health hazards such as diabetes, heart disease, and much more. However, they quote, “Fasting is, of course, an ancient spiritual and health practice, but it’s also a way to sidestep many of the ills of the modern world―including diabetes, heart disease, and cognitive impairment.” Ironic? I think not.*

On their website, they advertise that a person can lose an unreasonable amount of weight per week following the 16/8 rule no matter what they are eating. They also advertise that this 16/8 diet only has to be followed 3-times a week to see results. While this is a bold claim, it is not seeking out the health of the individual instead they focus on a number on the scale. There was no support e-mail or number to call when inquiring about questions of the program. The total cost for the 8-Hour Diet book is $26.99 plus $6.99 for shipping.

Do Dieters Lose Weight On The 8 Hour Diet?

After looking at the 8-Hour Diet book testimonials you would think this book is pure magic. The reviews are so one sided and cheesy, it is almost like they were purchased. I went to another site to get a read on some genuine testimonials from customers who have actually read the book, and tried the diet. Many people said the book was informative, but there were red flags when the quote “you can eat whatever you want” kept coming up.* This is not a true statement, as there are many foods that can be detrimental to your health long term if you eat whatever you want for however long you want. David Zinczenko also claims that you should incorporate low fat products in your diet, but we all know that the “low fat” symbols on processed food boxes just mean “higher added sugars” which turn into fat anyway!*

All in all, the general consensus was mixed, as there were many people who said they did not gain weight, nor did they lose weight. None of them felt that the book contributed to their overall lifestyle health, as no bad foods were being taken away from their diets. While the concept seems enticing, in order to become healthier you have to eliminate the bad out. With the bold claims all over their “scam style” website I would not recommend this book to anyone, as it has not been backed up by science. Nowhere on the website does it mention medical trials, health trials, or clinical trials behind its empty claims.

Is The 8 Hour Diet Easy To Follow?

The whole idea of the book comes from the times of day you are eating. As long as you know how to tell time, this program is easy to follow. After all, you could snack on Twinkies, ice cream, and soda pop all day long (as long as you are within your 8 hour clock) and they claim you will lose weight. I think this book is way too good to be true. The hardest part about the whole thing would be to actually “read” the book, and to lose money once it does not work for you. While many would say, “if you are looking to diet you would not eat unhealthy snacks anyway” they are terribly wrong, as many people don’t have the self-discipline to take the addictive foods away if they don’t have to. Long-term weight management is about finding healthy times of the day to eat nutritious snacks, and meals without getting bored.*

While the authors promote healthy food in their book, it is really up to the customer how they want to go about the diet program. Just like any diet program, it lures people in on empty promises especially because we are such a “quick fix” society.

This diet book is sold on Amazon, and their personal website promotes quick weight loss, while eating whatever you want. This book may work for some people, but the way they market the message screams, “scam” to me. While intermittent fasting to an extent has been known to help the body process food more efficiently, it is important to be giving your body wholesome nutrition to process in the first place. The authors were not off on a bad track, but they tried to market freedom of food, whether good or bad when speaking about one’s health. This in itself does not seem like a good process to follow. This company is simply a book, and nothing more. They do not have a support system, social media sites, or genuine testimonials on their website. Do with it as you may, but I am saving my money and time from this scam of a book.

  1. I’m back and after a 8 day experiment on the 24-hour fast, I found I’m better suited for the 8-hour protocol. On the 24-hour diet, by 5:30pm, I was ravenous and didn’t like the feeling. Especially, when I couldn’t even eat a small portion of my dinner. I took a few bites and started feeling very uncomfortable, almost to the point of pain. This went on eight days. You’d think I would have lost a ton of weight, but I lost and gained the same 3 lbs.

    My problem, after much thought, was my two 4 oz glasses of wine in the evening. I mean good red wine; not the cheap shi#. Anyway, I had to learn the hard way that alcohol and weight loss just don’t mix, so until I lose a substantial amount, I will refrain from imbibing.

    I do not eat junk. I am ketogenic and will eat this way forever. You can’t have it both ways. If you want to get and maintain your health, you must eat accordingly.

    Okay, I’m done.

  2. I’m back with a new review. I am no longer doing the 8 Hour diet, but have switched and have better results in two days than I had with the 8 Hour diet in 3 weeks. One thing I will say about the 8HD, is that I wasn’t hungry for the rest of the day after eating my first meal at 1:00 p.m., but I still still ate dinner with my husband in the evening and I thought, why eat, if I’m not hungry”? That did it for me! I am now on the One Meal a Day program and this is day two.

    I have lost over 3 lbs. in two days. My caloric intake is 1650 calories, which is the weight a woman 5’6″, who weighs 130 lbs. maintains. The 8-Hour Diet was an experiment that led me to my program that will get me to my goal weight. I will only weigh myself this first week and afterwards, will weight once a week only.

    I am on the 8 hour diet, not for weight loss as much as reflux. I eat HEALTHY between 8 & 4, after 4, I only drink water. Having been on this plan for 2 weeks, I can say that I have not had reflux since the first night. My clothes are looser but I have not weighed. I am not a bread or sweet eater. I do not use artificial sweetners nor drink sodas. My only vice is sweet tea and, being from the South, I can’t help it. I eat breakfast, snack, lunch, snack and am consuming about 1200 calories in the 8 hour time frame. We went out to dinner one night and I ate a 6 oz sirloin and half of the steamed veggies they brought. I stayed up an hour later to give the stomach time to digest before I laid down. If I lose weight, this will be an added bonus. No reflux is the best side of this.
