What’s Wrong With The Zone Diet?

By Mark Sisson
57 Comments

The ZoneDear Mark,

I just watched your video about the 2 minute salad; simple, fast, and no measuring. I agree with the primal way of eating and I’m torn between the freelance style of PB and structure of The Zone. What is your opinion of The Zone?

First, let me thank Rob for his question. I’ve had a lot of conversations about The Zone and other heavily publicized diet plans. It’s fair, I think, to look at the good and the bad of the diet. Unless you’re talking about the grapefruit diet or similarly comical fad, diets generally have to have at least some positive point(s) to gain a decent following, as The Zone has. Nonetheless, what can initially look like a rational foundation begins to show cracks when you look at how the philosophy actually plays out.

The Zone’s Positives?

It suggests vegetables and fruit as the primary sources of carbohydrates and fiber. It suggests more protein than most popular diets. It appreciates the value of omega-3s. And finally, it pays homage to the diet-hormone connection (although I take issue with how the theory gets applied in the actual diet prescription).

The Zone, I’ll say, isn’t by far the worst diet out there. It gets a few key things right or somewhat close. That said, however, I think there’s big room for improvement.

Since you asked, here are my “beefs” with The Zone.

The “Moderate” Hobby Horse

In Dr. Sears’ words, “Any diet that uses the word high or low to describe it is hormonally unsustainable. The only diet that can maintain hormonal balance for a lifetime must use the word moderate to describe it.” Just from a rhetorical standpoint, this statement gets under my skin. O.K. – moderate according to what culture, what historical (or pre-historical) age? Based on his theory, we’re genetically designed for a 40-30-30 plan kind of “moderation”.

The Fear of Fat

What’s with the dinky serving of almonds or avocado in each meal? Yes, monosaturated fats are great. So, why the miniscule serving? And then there’s the commandment about only the leanest meats. Sure, I get the fat-toxin connection, and it’s why I tend to often (but not always) choose relatively leaner meats, but this has nothing to do with The Zone recommendation. Dr. Sears, pardon my saying, just seems like another fat-o-phobe. But, with the higher carb allotment, I guess fat gets you into more trouble. (What about that little bit of biochemistry? Didn’t see that mentioned. Hmmm.)

Too High in Carbs

I already said that I applauded the focus on veggies and the secondary role of fruits. It’s true that The Zone downplays the role of grains, and I like that as well. (Little surprise, yes.) But here we find ourselves back in the land of unfounded, forced “moderation.” Sure, Dr. Sears talks insulin regulation, but the rubber doesn’t exactly meet the road in The Zone diet. For an eating plan to truly facilitate hormonal balance, you have to put the brakes on the insulin response. This means low carb. But that’s a bad word in The Zone.

Hunger

Without the fat, most people are going to be hungry on this diet. I know I would be. I’m not one for diets. Hunger sets in (on a regular basis, no less), and too many well-meaning people are set up for failure. In contrast, the Primal Blueprint is a sustainable lifestyle that offers a model for eating that a person can realistically stick with over time.

Too Structured

Along with the hunger issue, imposing too much structure is too hard (or tedious) over time. I guess it might be easier if you took a Sharpie to all your dinner plates for the assigned pie graph. The plan even goes so far as to set out specific time intervals for eating. For example, eat within an hour after getting up. Eat dinner within 2 ½ hours of the prescribed afternoon snack. You should eat five times a day total. The more structure, the more confusion and temptation there is when a dieter gets off track. Again, I’m all about what’s sustainable. Experience has taught me that the fewer and more simple the guidelines, the better. Maybe that’s just me. On a true low-carb program, the more you learn to burn fat, the less hunger becomes an issue and the less often you need to eat in a structured fashion to sustain energy.

Protein Suggestions

While the 30% is more than most dietary organizations or popular diet plans recommend, the absolute hard and fast rule again doesn’t sit right. You don’t need to be an Olympic athlete to benefit from more than 30% protein intake. And, no, it won’t necessarily turn to fat – unless you drive it there with the higher carbs. Finally, Dr. Sears touts soy as one of the best sources, saying that using soy as a primary protein source could be the healthiest choice overall. Most of you know my take on soy, and I stand by my opinion. The research in that vein keeps coming. Too bad The Zone hasn’t caught up with the times on that one.

So, you’ve heard my take now. I’d love to hear your comments. Anyone here tried it before and want to offer up some personal anecdotes? Thanks for reading. As always, thanks for the great questions.

Hi Mark, For me it is the “Too Structured” point which has the most resonance. The more rules there are to follow the more trapped a person feels and the less likely it is to be something they stick with. I have seen this happen time and again with people I know who have been attempting to follow one regime or another. The fact remains, as you and others have pointed out time and again, that we have evolved to eat in an unstructured way, therefore it makes sense fundamentally that our system should be optimised to deal with the… Read more »

I don’t know about the diet since I haven’t tried it, but I find the thought of the structured part to be almost freeing. Then I don’t have to think about what and how much to eat, it is already laid out for me! ha. Maybe I am just a lazy eater, but I am intolerant to so many foods that cooking and eating is such a chore to me! So. MUCH. PLANNING! So…I think I would like the structured eating. I know my husband also works well with that kind of schedule and portions, etc. Just an alternate view… Read more »

I used to follow the BFFM (Burn the Fat, Feed the Muscle) program for exercise and eating. The eating was very similar to The Zone as far as the Protein-Fat-Carb breakdown. At the time, the structure was what I needed; having to keep track of p-f-c ratios at every meal in a food log made me very aware of what I was putting in my mouth. But once I got a grasp on the content of various foods, keeping the log was counter-productive. Measuring everything out was a pain in the a$$, and it actually made me HUNGRIER by forcing… Read more »

Without rules and structure, we’d be back in the Stone Age…lol Good for civilization. Good for diet. –So why after you got to know your foods and their measurements (doesn’t take all that long), did you keep doing it? Habit? Why didn’t you just get to know the structure and amounts and be done? Hence, eyeballing, and we’re back to the plate division (which works just fine). It hasn’t derailed me or made me hungrier or obsessed. I can’t follow a plan and glance at food and know whether it’s real or not? And then put it on my plate… Read more »

The rules and structure of how to feed our body are a lot more complicated and more in line with fractal and chaos theory – not the childish kindergarten schedules of how much and when.

Do you fill the petrol in your car on a religios schedule, the same amount, at the same time each day, each week – or do you fill the tank in line with consumption needs.

Er.. Gasoline is not exactly like food, it’s just a simple source of energy that gets consumed by the car. Food interacts with the body via chemical reactions that depend on the food itself and on the individual. Just as an example, if you fill the tank up there won’t be excess gas that will be stored for future use as opposed to lipids. So comparing refueling to food intake is a bit far fetched 🙂

This actually got me thinking about something a little different. When I was in my teens and 20’s, I could eat practically what I wanted (within reason) and moderate my weight. I experienced low blood sugar problems (I guess reactive hypoglycemia) and had a few episodes of weight gain, but nothing I couldn’t reverse with a little (or a lot) of exercise. As I got older (even late 20’s) it became harder and harder. That’s when I found low-carb and finally, 15 years or so after starting my nutritional journey, Primal/EF/Paleo. A lot of the “experts” that tout eating plans… Read more »

I would agree that a lot of diets do set us up to fail. I think the sensation of feeling hungry will be their for a while depending on how much you are used to eating. But in a few weeks up to a month, the hunger will go away if you stick to the diet.

Mark You make good points about the Zone, but let me tell you my experience with it. I started the Zone about 2 years ago and have been over 90% strict with it since (although I have modified it some…more on that to come). It was a great starting place for my diet. I disagree with your statement “The more structure, the more confusion and temptation there is when a dieter gets off track”. I think that the more structure, the less room for error, the less you have to think about it, and the easier it is to follow… Read more »

“The more structure, the more confusion and temptation there is when a dieter gets off track.” Nothing could be more true for the constant dieter. The points system, the miniscule calorie counting, and the “just eat a bunch of this one food” diets are doomed in the long run simply because they suck the joy out of eating. Has anyone met a person who has stuck with SlimFast, the cabbage diet, or any other “get thin now!” plan for 20 years? That’s the great thing about Mark’s Primal “diet.” It’s more about gaining a sense of healthy vs. non-healthy foods… Read more »

Mary, You bring up a good point that structure can eliminate confusion, but it also limits variety. The structure works for the type of people who become comfortable in a fixed routine: same meal every work day, one of three different dinners every evening. You could argue that almost any diet works if you adhere to it. The reason most fad diets fail isn’t because they aren’t healthy, it is because people simply get sick of the routine, or because the restrictions the diet creates leave the dieter in a constant state of hunger or a lack of energy. Admittedly… Read more »

Mark, what do you think Loren Cordain’s book called Paleo Diet? He also suggest to eat lean meats and to be moderate at saturated fat. He thinks hunter-gatherers ate about the exact amount of saturated fat like the dietetion’s advice.

The zone is a great place to start to understand “how” we eat: portions, timing, macronutrient ratios. Other than “three square meals a day” and “be sure to eat breakfast” what cultural cues do we have? Certainly the zone is not optimized for everyone, but think of Sears’ “moderate” approach as a good “average” diet — once you’ve mastered its basics, you’re free to optimize it to meet your specific needs. Paleo/PB is awesome for learning “what” to eat. More fats, real food, etc. Using the Zone structure, I worked on increasing the quality of my foods, slowly upped the… Read more »

Josh – I completely agree. I have merged Paleo with Zone and incorporate much of what I learn on Mark’s site as well. Jarod – I partially agree. You can still have plenty of variety on the Zone. Heck, technically you can eat anything you want, as long as you keep your portions under control. I’ve never found much joy in eating; it’s just another thing I do every day. So I could care less than I eat more salmon and broccoli in one week than most people eat in their lifetime. But, understandably, most people have a larger emotional… Read more »

Les, Cordain has some good ideas (obviously), but I disagree on the sat fat restriction. If you eat low carb and clean fats/proteins, there’s little reason to eschew saturated fats. And there’s no evidence that sat fats lead to heart disease. I think he’s just trying to appeal to all. Mary, if you start eating PB all the time, you get to a point where your hunger is the guide. I, and many people I work with, certainly don’t feel the need to measure, weigh or eyeball anything anymore. You eat too much at one meal, you naturally eat less… Read more »

I have in the past been a big pusher of the zone, but I found myself really obsessed with eating due to the math involved in eating anything. I had a thought this balance thing though. Barry Sears calls certain hormones “good” and others “bad”, and I know he is just using those words so his book is easier to read. But I can’t help but notice that our bodies can and do survive in imbalanced hormonal states, and that it seems reasonable that we evolved to frequently handle wild shifts in food sources from season to season, from one… Read more »

Structure is a matter of personality. Some folks do well with structure. Others abhor it. I personally can do without structure when it comes to eating (at work I’m different). I just eat lots of protein, fat and veggies with a good mix of fruit thrown in, and I’m good. Glucose Tolerance test went from 198 to 100, BP down 25 points…I don’t measure or worry about it If getting too much of a % of a certain item. That would drive me nuts and make me hate my me eating style. In my mind, when I have to start… Read more »

I just dove right in. Then I started reading, beginning with “Good Calories, Bad Calories” by Gary Taub. This is when I switched from the Zone to a Paleo Atkin’s diet.

When I found the Zone diet in 1996 it was the most amazing diet I ever did. The portion control and balance worked really well for me. It was great to at last find a programme that got rid of PMS, low evergy levels, and excess body fat. Over the years I have followed it guesswork – without stressing over it. It was great to be able to eat anything and know if I kept to the portion and balance I wouldn’t put weight back on. However I suffer auto immune joint inflammation and my PMS would come and go.… Read more »

I did The Zone a couple of years ago, and it “worked” in that I lost weight. What did not work was that I was starving the whole time, and all the math drove me crazy! One thing I was confused about, Mark, was you saying that The Zone is higher protein than most diets. It may be a higher percentage of total calories, but since it is so low calorie to begin with, the actual grams that you get of protein are still very low. I am short, and The Zone tells me that I can only have around… Read more »

I also followed it the entire 18 months that she was nursing (she weaned herself at that time.)

Hey,
I’ve just been reading the zone diet and finally worked out how many blocks etc….. seems pretty complicated.

I’ve also bought the Primal blueprint 30 day pack which I’m halfway through as well!

A lot of people are saying they use a zoned paleo approach to eating with added good fats (which to be honest actually sounds like a zoned primal diet).

Whats your spin on the arachidonic acid in foods? particularly in eggs?

I think you misunderstand a lot of the theory behind the zone.

The 30:30:40 ratio is only for weight loss. Dr. Sears explicitly states that you need to add sufficient unsaturated fats back into the diet once you have reached your ideal weight. This should significantly increase the fat blocks as was mentioned by a previous comment.

Also, the amount of protein is based on lean body mass and the basic recommendation is for sedentary individuals. Eating more protein, based on your activity level, is explicitly discussed and recommended.

Been on the Zone for 10+ years and blood tests don’t lie. In the optimal range for most. Your beefs with the zone diet are minor and easily explained. It is not a high carb diet. It is a carb adequate diet. When you have low glycemic load carbs you can eat more. It is not a low fat diet. 30% is not low it just looks like it because of the density of fat. Dr Sears says it is important to keep the protein to carb ratio intact and if you need extra calories to put in more fat.… Read more »

The zone can be done in a lot of ways. For a basic sedentary person: 3 meals (3 blocks) and 2 snacks (1 block) For an active person: 3 meals (4 blocks and 2 snacks (1 block) For a very active person: 3 meals (5 blocks and 2 snacks (1 block) For full time athletes: 3 meals (4 blocks each) and 2 snacks (2 blocks). To top up extra calories eat extra mono-unsaturated fats (nuts, avocado, etc). It is trivial to get the portions correct or close enough.

I am a fan of Dr. Sears. FYI, one should read his books in depth before coming to such quick judgments. The Zone ‘diet’ is for weight loss. For maintenance, it requires tweaking such as adding additional fat. There are other zone prescriptions as well, such as Zone for Athletes, which address how to fuel longer or harder workouts. Grains are included in the food blocks, but you don’t necessarily have to eat them if you don’t want to. On a personal note, I remember seeing Dr. Sears getting grilled by ‘nutritionists’ back in the early 90’s on Oprah, I… Read more »

I little bit a knowledge is a dangerous thing. Dr. Sears has a PhD. Many others simply fall hook, line and sinker for any fad diet that happens to be better than the standard American diet (which is just about any diet) without any nutritional education. If you are looking for health and athletic results, modernate carbs, for many, are the way to go. I do not believe any Gold medals, marathons, championships, or anything athletic were won on a low-carb diet? I admire anyone who is passionate about health but you need to be careful when giving nutritional advice.

Wow, I cannot believe some of these responses! The Zone is a guide-line, one which is easily adapted for people with different life styles, be it paleo, vegan etc. The key is ratio, and I feel this is overshadowed by comments here regarding portion sizes and structure. Let’s be perfectly clear, the Zone diet is primarily for weight loss. Maintenance or training requirements are going to be different; if you are already at a relatively low body fat percentile, obviously you can have more monounsaturated fat, and more calories in general. Grains, obviously worth avoiding all together, are severely restricted,… Read more »

I’ve been eating “in the zone” for about 18 years. I can tell you it’s sustainable. It’s easy to “eyeball” the ratio so you are not compelled to be super precise & measure your food out. I am 60 years old and run 50 miles per month, not an Olympic athlete, but feeling as good as when I was 19. I credit the zone diet with my good health and vitality.
