It can definitely be tricky to find foods that are paleo-friendly particularly when you are out at restaurants so it does require a lot of dedication.
Well, aside from the obvious group who bailed because they miss their pizza and french fries, there are actually people who manage to gain weight on one of these low carbA diets! The thing is, when you cut out carbohydrates entirely from your diet you need to replace them with something. Often people who get on these low-carb diets dona€™t actually track just how much fat they are eating!
They will throw back a few cups of almonds and cashews without realizing they just went well over their daily calorie target. One cup of almonds can be the difference between eating a 300 calorie deficit or eating a calorie surplus! It can be frustrating because it seems as though they are eating less food by the physical size of what they are consuming.
Now, we dona€™t want to write these diets off completely because they can and do work for many people out there. If, however, you are in the group of people who function well on paleo you need to watch your calories carefully. As mentioned earlier, fatty foods like almonds and cashews contain a ton of calories so make sure you are measuring out exactly what you are eating and recording it in a journal. Likewise, make sure you track your weight over time – dona€™t just assume you are making progress because you are eating low-carb diet. Dona€™t deny your body carbohydrates if doing so will cause you to lose muscle mass and feel tired all day – that will only hurt your gains in the long run and make you waste time putting the muscle back on that you lost during your cut. Most importantly, track those calories going in every day – if you stay disciplined and hit your target deficit while eating the right foods and doing resistance training you will make progress, guaranteed. It might be a good option for some people out there to include a proven and effective fat burning supplements into their diet. Make sure to know what ingredients to look for in our guide on the best ingredients for fat burning supplements.
There are several layers to this and, frankly, there are some things we can’t fully explain – I’ll always acknowledge this.
Take a look again at the figure below, which shows you how many calories folks are consuming on each diet and, more importantly, where those calories come from.
You’ll note that people on these diets, including the strictest low-fat high-carb diets, significantly reduce their total amount of carbohydrates (therefore reducing the amount of insulin they secrete). The reason, I believe, most of these diets have some efficacy – at least in the short-term – is that they all reduce sugar and highly refined carbohydrate intake, either explicitly or implicitly. Someone made a great point in response to my post on why fruits and vegetables are not actually necessary for good health. I know a lot of people who eat this way and, I’ve got to say, these folks do not eat a lot of sugar or a lot of highly refined carbohydrates.
While I do plan to write an entire post on this topic of what one can and cannot conclude from an experiment, I do want to at least make the point here: The biggest single problem with nutrition “science” is that cause and effect are rarely linked correctly. I am, to be clear, not implying this is the case for this trial, but I want you to understand why it’s important to read papers fully.
This trial, The Lifestyle Heart Trial, prospectively randomized a group of not-so-healthy patients into two treatment groups: the control group and the experimental group (or what we’d call the “treatment” or “intervention” group). First off, and perhaps most importantly from the standpoint of drawing conclusions, compliance was reported to be excellent and the differences between the groups were statistically significant on every metric, except total average caloric intake.
Take a moment to look over the rest of the table (or just skip reading it since I’m going to keep talking about it anyway). Though not shown in this table, the experimental group also reported less chest pain severity (though chest pain frequency and duration were not statistically different). Let’s take a leap of faith and hypothesize that the dietary intervention (rather than, say, the social support) had the greatest impact on the measured parameters in the subjects. It’s certainly the most likely factor in my mind. But what, exactly, can I conclude? People don’t like to be hungry, and if they are reducing their caloric intake by reducing fat intake, they seldom find themselves satiated.
Semi-starvation reduces basal metabolic rate, so your body actually adjusts to the “new” norm and slows down its rate of mobilizing internal fat stores. I argue that reduction of fat intake has nothing to do with it and that the reduction of total calories has a transient effect.
It’s *really* tough to study this stuff properly, especially compared to studying things blood pressure lowering pills, which are complex in their own right, but MUCH easier to control in a study.
A nutrition department of a university accepts funds from a company that makes confectionery. Do you think the Academy’s supporters want to hear that if you eliminate their products you will no longer need to rely on the products provided by the biggest supporters of the Diabetic Association? Pretty much solely because of their report, Suzuki was forced to eventually withdraw the Samurai from production in the US although they later won the lawsuit that was filed as a result of the forged report by showing videos from the actual testing of the car conducted by CR. Ironically, the fact that CR had to admit it was faked somehow wasn’t plastered all over their magazines and the front pages of a bunch of newspapers. At that point, everything they publish became suspect and may as well line a birdcage somewhere. Peter, I have a coworker who has recently lost 80lbs over the course of a year on weight watchers.
Looking forward to your next post, and of course people's comments for the current one!
I will discuss all of this in great detail, hopefully in the coming month, when I do a post on PUFA (polyunsaturated fatty acids).
Anyway, it’s nice to discover someone who takes the Taubes viewpoint on things, and also takes the time to actually post online about it with some frequency, so thanks! Oh absolutely, I was mostly referring to the fact that most of the excess carbs we eat are converted to palmitic acid, which is a SFA.
There was an (1) average protein, low fat group (65% CHO), (2) High protein, low fat group , (3) Average protein, high fat, and (4) high protein, high fat (35% CHO).
Thanks very much, Bob, both for the kind comments and for sharing the other data with folks. Any workout routine should go hand in hand with good nutrition and a balanced diet, so the question of low carb diets is one that should be addressed here.
Yes, if you reduce your calories you can lose weight, and yes if you avoid too many carbs you can lose weight. If you’ve ever tried dieting or weight loss before, reducing your carbohydrates was probably the first thing you did. The common school of thought is that carbs are generally bad and the cause of weight gain from insulin turning excess blood sugar (Caused by carbs) into fat. While this does happen if you eat a diet based mostly on carbs, it does not mean all carbs are evil and should be avoided. In fact, if you want to build lean muscle and tone up, you will need carbs just like you will need protein (though in smaller amounts). So, what I am trying to do here is tell you that low carb diets have been successful in the past, but they are not necessarily the best way.

With the explosion of popular low carb diets like Atkins and Paleo it seems as though the world has turned its back on carbs – and warm up a lot more to fats. Given the size of the people in most developed countries ita€™s quite obvious that most peoplea€™s priority is to lose fat and not necessarily gain muscle, hence this article should be applicable to a lot of people out there. Having said that when followed properly these diets do have the potential to help people lose a lot of fat quickly. Most low-carb diets will advocate a certain amount of protein (around 150 grams for example), about 50 grams of carbohydrates and the rest coming from fats. You see, fats contain 9 calories per gram, which is more than double the 4 calories per gram found in protein or carbohydrates.
As a result, if you want to be successful on one of these low-carb diets you really need to monitor your fat intake carefully.
However, once you account for the calorie density of fatty foods you see that they are consuming just as much if not more! There is a possibility that you could be over-eating if you arena€™t actually tracking your calories in.
If you are able to function well and lose weight at a steady pace while on a well-balanced diet then you should stick to that.
Especially on low carb diets people have a lack of energy, that is were many use aA fat burning supplements to get that extra energy & speed up the grueling fat loss process. Some of these products are however a complete waste of money with ineffective and outdated ingredients. That said, many of the successes (at least weight-wise, though hopefully by now you realize there is much more to health than just body composition) of popular diets can be explained by a few simple observations.
You can argue that those who are overweight probably consume an even greater amount of carbohydrates. Even the Ornish diet, which is the most restrictive diet with respect to fat and most liberal with respect to carbohydrates, still reduces carbohydrate intake by about 40% from what people were likely eating pre-diet. No one on the Ornish Diet or Jenny Craig Diet is eating candy bars and potato chips, at least not if they are adhering to it. The point was, essentially, that telling people to eat 5-6 servings per day of fruits and vegetables can hopefully drive a beneficial substitution effect. I have no intention of engaging in a battle with proponents of plant-based eating or no-saturated-fat diets.
Stated another way, it’s one thing to observe an outcome, but it’s quite another to conclude the actual cause of that outcome. In other words, for every intended difference between the groups a difference existed, except that on average they ate the same number of calories (though obviously from very different sources), which was not intended to be different as both groups were permitted to eat ad libitum – meaning as much as they wanted.
Ornish’s study? I think the reduction in sugar and simple carbohydrates played the largest single role in the improvements experienced by the experimental group, but I can’t prove it from this study any more than one can prove a low-fat vegetarian diet is the “best” diet. We can only conclude that it’s better than eating Twinkies and potato chips which, admittedly, is a good thing to know. And, the majority of the benefit folks receive comes from the reduction of sugars and highly refined carbohydrates. Case in point…they recently reported that olive oil is not good for you because it does not contain omega 6.
3, has a good point about some plans (including WW) having the advantage of group support, which I think is a very major confounder. It is wonderful to watch these people glow once they have found some sort of solution to their weight problem. One of my favorite things to say to people who are scared of saturated fat is that even on an entirely plant based diet, (ala Ornish Diet), if they are restricting their caloric intake, their bodies will be running on the saturated (animal) fat that they have stored on themselves. For example the degree of unsaturated fatty acids in our membrane bilayer probably plays a role in our insulin sensitivity, just as one example.
I will briefly talk you through their methods now, but you would be wise to follow the links and read the article if you want to really understand low carb diets. This is because your body got used to the new conditions and the effectiveness was reduced.
I've been using Kettlebells for over two years, and am a firm believer that men and women can do very similar routines and exercises, yet get the different results they desire.
There are tons of articles out there describing the benefits of such a diet so do a quick google search for a€?atkinsa€? or a€?paleoa€? to learn more. Some people work very well on a high protein and high fat diet while others feel very lethargic and report significant strength and muscle loss. But for the purpose of simplicity, let’s assume even the folks who go on these diets are consuming the national average of approximately 450 grams of carbohydrate per day (in compliance with governmental recommendations, as a percent of overall intake).
If you tell someone who eats Twinkies, potato chips, and candy bars all day to eat more fruit (and they do), you’ve almost guaranteed an improvement in their health if they eat bananas and apples instead of the aforementioned junk food. I’m reasonably confident that the proponents of these diets are good people who really want to help others and have nothing but the best intentions.
Ornish was the principle investigator on a trial published in the journal The Lancet in 1990.
In other words, there were not enough subjects in the study to determine a difference in these “hard” outcomes, so we can’t make a conclusion about such events, only the changes in “soft” outcomes. Good science, bad interpretationGravity and insulin: the dynamic duoIf low carb eating is so effective, why are people still overweight? His clinical interests are nutrition, lipidology, endocrinology, and a few other cool things. Eg, the criticism of the Ornish Lifestyle Heart Trial is excellent (and I LOVED the kitten-stroking quip), and really could and should have stood alone. After short diologue with her on the particulars of her daily intake I quickly realized her consumption of carbohydrate was significantly reduced and eliminated almost all fructose. In this stage of the ideal diet, there is a further calorie reduction to really spruce up the diet. Popularity, of course, was determined by a number of factors, including compliance with current government recommendations (sorry Atkins), number of people who have tried the diet, and reported success on the diets.
That doesn’t mean bananas and apples are “good for you” – it just means they are less “bad for you.” Here’s the kicker, though. But that doesn’t mean we can or should overlook the errors being made in drawing their conclusions. I’m not discounting soft outcomes, only pointing out the distinction for folks not familiar with them. They never factor in that the chicken was breaded or that when someone ate steak or fish they had a large amount of bread of potatoes along with it.
We’re led to believe that the reason such folks get leaner and more healthy is because they are eating more fruits or more vegetables or more grains or more [fill-in-the-blank], rather than because they eliminated the most egregious offenders from their diet. Ornish personally, and I can only assume that he is a profoundly caring physician who has dedicated his life to helping people live better lives. But as always, I STRONGLY encourage folks with access (or folks who are willing to purchase it) to read the paper in its entirety. For people who don’t want to read the study completely, or who may not have much experience reading clinical papers, I want to devote some time to digging into this paper.
The end conclusion is the whole thing must be bad and therefore needs to be reduced or outright expunged from the diet. I recall hearing Gary talking about his discussion with a participant from the Biggest loser on Larry King and the rapant weight gain after the show. It’s hard to tell if this change was statistically significant by inspection, so you glance at the p-value which tells you it was not. That is one big difference I’ve noticed between studies cited by writers who want to condemn the entire diet consumed by Americans vs those who look at it with a more in depth eye and realize that certain components are the problem not the whole diet across the board.
Why did the people in the China Study who ate more plants do better than those who ate more animals (assuming they did)? Well, for starters, reading abstracts, hearing CNN headlines, or reading about studies in the NY Times doesn’t actually give you enough information to really understand if the results are applicable to you. Parenthetically, if you actually want the answer to this question, beyond my peripheral address, below, please read Denise Minger’s categorically brilliant analysis of the study. Beyond this reason, and let me be uncharacteristically blunt, just because a study is published in a medical journal it does not imply that is worth the paper it is printed on. Steve Rosenberg, once told me that a great number of published studies are never again cited (I forget the exact number, but it was staggering, over 50%). Translation: whatever they published was of such little value that no one ever made reference to it again. The thing is, it is possible to eliminate wheat and still eat way too many carbs (can we say ice cream?). I’m now happily in ketosis, and the best part is, I know the WHY of weight loss now, how totally liberating and hope giving.
