Dining by Traffic Light: Green Is for Go, Red Is for Stop

Video taken from the channel: NutritionFacts.org


A study from the University of Pennsylvania found a traffic-signal code, a three-color coding with green for low calorie, yellow for medium and red for high calorie, led to a 60-calorie drop in what people ordered. This simple trick would account for about a six pound weight loss over a year. The color coded labels acted as a reinforcement of value—people were willing to spend more money on foods labeled green than on foods labeled red. [2] Cool!

So, the schema of traffic lights can help you make better eating decisions. The only problem? This system doesn’t actually exist.

They put traffic-light labels on their cafeteria’s menu to signal the healthfulness of dishes. Color-Code Your Food (Green Means Go!) Could these changes really help people lose weight. Traffic signals and signs should appear the correct color to anyone with anomalous trichromatic vision wearing these glasses. Note that these glasses do not work for dichromatic vision (protanopia, deuteranopia, tritanopia, or red-green indistinction) or monochromatic vision. The yellow stop-sign craze began in Detroit in 1915, a city that five years later installed its first electric traffic signal, which happened to include the very first amber traffic light, at the.

According to Reader’s Digest, the color blue suppresses appetite, so making it part of your eating plan can help your weight loss efforts. The color-therapy expert website Lightstreamers recommends exchanging the small bulb inside your fridge for a blue one so you’re less tempted to snack every time you open the fridge. So many times I have got many help from warriors.

Hope that this time I will not be disappointed too. After working for 1 month I have made a complete weight loss sales funnel. Before that I did all direct marketing.

But now I really want to start building my own list. For the last 10 days I have tried following traffic. The trick to losing weight may have something to do with the color you surround yourself with, say experts. Turns out, the color blue may have some real weight-loss benefits.

Turns out, the color. Can colors curb your appetite and help you lose weight? Maybe. Could the color of a plate be a key to weight loss? A recent study says, “Yes.” New research* suggests that plate colors that contrast with food help people eat less.

The study revealed that people put less food on a plate with high contrast. The goal of this diet is to eliminate all those foods that makes us gain weight while choosing those that help us getting back in shape. Traffic lights have three colors: red, yellow and green, and to each color correspond a group of foods.

Let’s find out how this regime works! How does the traffic light diet work?

The colors of the traffic light are also used to help families identify which activities to increase (green: moderate-tovigorous physical activity) and to decrease (red: sedentary behaviors).

Not only do these colors have cultural meanings (red for stop; green for go), but the essence of a scale is to see it as a continuum, and changing colors for different portions of a scale may result in respondents seeing the scales in quite different ways.

  • Vegans could be for various reasons or multiple reasons. If it’s for ethics, it doesn’t matter if it’s healthy and environment-friendly. If it’s for environment, ethics or health doesn’t matter to them. If it’s for health reasons, environment and ethics doesn’t matter much.

    I try to check all criteria usually. But mostly, at top priority is for ethics, for justice for all. It’s a fight against cruelty & injustice on humans and non-humans both. I believe, healthy mind is more important than healthy body. Healthy body may not have a healthy mind. And it’s of no use. Mental illness is far more dangerous than physical illness. Isn’t it?

    Stay healthy, stay mindful:)

  • I’ve heard arguments for and against Kombucha… Does anyone have reference to a study showing benefits? Or can you do a video on your thoughts! Thanks folks.

  • I agree with the overall message here. But would you include stevia as unhealthy processed? It doesn’t offer much in nutrition (little bit officer) but since it costs 0 calorie dollars and has no negative health effects that I know off, well. It’s amazing as an aid to consume more oats.

  • He doesn’t have his morals straight he kind of reminds me of the Nazi scientist, who, as long as it doesn’t harm “his people” he doesn’t give a shit if the action itself is completely immoral. Also he has to lean the difference between “better”, and “less bad/evil”. Thumbs down from me. He is a speciezist after all. If we talk about mental health, or health in general you can’t put a blinder on ethics, and call yourself a whole, healthy human you are a blind criple… mental is connected with physical, and one day it will catch up.

  • This is my favourite video of yours ever. So true “whole food plant based” all the way. Btw the animation is incredible. Thank you. ❤️

  • In UK the health service got close to get the semaphore labels. But the breakfast cereal companies blocked it as they are full of sugar and got red lights. And they sell mostly to kids. Truly evil people.

  • I’ve had a similar perspective after reading dr. Weil’s eating well for optimum health back in 2000. Although quite different in recommendations, after ripping through the book in a weekend, it was an easy read, I put food into one of four catagories: never, rarely, occasionally, and frequently. It served me well.
    Sadly, I bought three copies, gave them to friends and family who were interested in health, and they were all returned untouched. I don’t want to be judgmental, but I guess even when it comes to nutrition, the obstinence is off the charts.

  • Had to share this to my Facebook Page. This is a tremendous little video enabling us to explain to others why we eat this way! Thanks, Dr. G!

  • 20104
    I think traffic light label is a good idea! It can help us distinguish whether the amount of fat, sugar or salt is over what we need. I hope it can implement in our lives someday.

  • I think Dr. Greger stole the idea from Dr. McDougal’s traffic light system.
    Go check:
    https://www.drmcdougall.com/health/education/cpb/
    Its okay that he use it but he must’nt call it HIS invention.

  • Thank you. I come across so many trying to eat this way and they over stress themselves trying to do 100% compliance 100% of the time. They freak out and feel they’ll instantly die if they go out to eat for a birthday dinner or something. Congrats on your eating disorder. What I get from the video is, when you can, choose better foods, or do the best you can. If you slip up today, do better tomorrow. Live your life as best you can.

  • 20119
    After watching this video, I support that the traffic light should be kept every store because health is far more important than wealth. All the people have to keep this idea in mind.

  • Thanks Dr. Gregor! As always, great video. I’m a little confused by the comment at 4:41 however. Are you saying that almond milk is a processed food? All almond milk is is whole almonds blended into water. There is certainly “nothing bad added” or “nothing good taken away” as you mention earlier in the video.

  • I agree (humbly) with and trust your nutrition knowledge, and thank you for your immense contribution. But get this straight Dr Greger, I am not pleased at all with you and other plant-based doctors constantly dumping on vegans to put your point across. I would hope that you realise that college students (or people with eating disorders) may not actually represent the whole vegan population, and as a very healthy vegan who eats little junk food I am offended, and it only makes my life much harder when you, as a trusted source of information, ridicule my very healthy lifestyle. Next time you make a video like this, leave out the unnecessary negative vegan comments, it will be just as effective.

  • Dr.Greger, Can you do a video on Nightshades? There are a lot of misinformation that doesn’t give clear answers to if they are ok or not.

  • A lot of pitchforks over knives in the comments. Accusations of contradictions, selling out, mixed messages, and more. Odd…I didn’t get any of that from the presentation. Dr. Greger was comparing one thing to another, explaining the three light system. Like a bullet in the foot is better than in the head! Then some comments interpreted that getting shot in the foot is healthy, according to Dr. Greger! Come on, people!!! ��

  • I went plant based for 6 months my energy level was amazing! I loved it however, I was bloated and constipated and really painful stomach it was bad. I then started eliminating whole grains and started to notice much better stomach symptoms is it healthy to take away grains? I mean I know they have a lot proteins too but my stomach does not digest them. I feel like it is not a complete diet for the day ����

  • Oh man all the vegans getting mad. Just because it’s vegan doesn’t means it’s healthy or better. It’s just a label to sell product these days (unfortunately). I respect the dietary choice and all but he talking colorfully here. Maybe trying to reach a wider audience. Instead of cutting out meat just have it occasionally. It’s healthier and a good start to cutting it out of the diet entirely.

  • I come to nutritionfacts.org for the science on a wfpb diet, optimal nutrition, not for a watered down version that says bacon sprinkles with your salad is okay. I think everyone understands that the closer you get to a wfpb diet, the better. I would prefer if the nutritionfacts.org team would stick to informing us on the science on optimal nutrition instead of wasting time telling us it’s okay to add this or that to ‘make the medicine go down easy’.

  • Dr. Greger please do a video on whether fermented foods such as sauerkraut are healthy. I saw your video on kimchi and than found an interview with Dr. Mercola which left me confused as to whether sauerkraut should be eaten.

    I think traffic lights labeling is a good idea, it is convenient and simple enough for children to understand. We would always have to make a balance between making money and doing good things for people. And also, it is a important thing to me that the labels use the same standard so that consumers could compare the products.

  • Probably simpler to just tell people not to consume refined substances like oil, sweeteners, juice, protein powder, tofu, seitan, vegan fake milk, salt, miso, refined flour, etc. In japan, the high fiber by product of making tofu is called okara and okara is used in japan recipes. I have bought fresh tofu and fresh okara from a nearby japan grocery store.

  • One of the things that I really appreciate is his distinction in which foods are best cooked vs eaten raw. There were one or more videos years ago which spoke of how the important nutrients are brought out by cooking, which I rarely hear about in vegan circles.. uncooked isn’t necessarily most healthy. I have TMJ and appreciate cooked

  • Good video. But I can’t help but notice that Greger’s position on nutrition has “evolved” quite a bit over recent years. Greger was a staunch vegan not long ago. His nutrition advice now is much more lenient. Nothing wrong with that, to the contrary, continually evolving and bettering ourselves is a virtue in my book. But it would be nice if Dr. Greger acknowledged his evolution on nutrition.

  • Wait now.. what’s wrong with blue/green algae?

    Edit: Well I found this from him. How odd. watch?v=74bbWmFhLzk and this watch?v=L5vdz637DWk

  • Not going to spam because I don’t need to but listen to this. Fatlossfacctor.info is one of the leading sources and fastest ways to lose weight. The program has over 100k Facebook likes and even more customers. Stop buying into all the hype of diet pills, body cleanses, and 2 minute workouts that promise you everything and then give you nothing. Weight loss takes commitment and if it was easy I don’t think 35% of America would be overweight. The program speaks for itself I don’t have to.

  • 20128
    After watching this video, I think food label with the colors of traffic lights are necessary for us since obesity is a problem of mine, but I have not seen this kind of label in many food packages.

  • Dr. G lectured on how domesticating pigs gave us the whooping cough pandemic, now bacon bits are okay? Is it that tough to say “Hey kids, don’t eat dead pigs. Not a good idea” Come on doc.

  • Jammer dat het filmpje voorzien is van Engels commentaar, want het geeft op een duidelijke manier aan hoe het verkeerslichtsysteem werkt. Maar misschien kan een betere techneut dan ik ben, het voorzien van hetzelfde commentaar, maar dan in verschillende talen? Ik zal het nu alvast aan mijn relaties als e-mailbijlage versturen. Want alle beetjes helpen. En kent u een journalist? Maak deze hierop attent! Publiciteit is de grootste vijand van onbetrouwbare fabrikanten!

    I think this kind of food labeling system is very good. It can help more people who wants to be healthier or who wants to lost weight like Barry.

  • 20124
    After watching this video, I have to say “wow” Because I have never thought this idea before, and it is so useful! Only with a glance, and then we can figure out what is the most healthy. As a person who pursue a healthy life, I want to say “thank you” to those people who found this way.

  • 20107
    I think this is a meaningful video! I think it will actually make the consumers think twice before they make any purchase. Good video! Thanks for the useful information!

  • MYCOTOXINS have a negative health effects on your brain and immune system-inflammation. MYCOTOXINS are found in beans, corn, chocolate, nuts, grains and coffee and would make a great video! Also Mycotoxins from mold in your house causes compromised immune system and can cause death.

  • The point is to be consistent. We need to be clear in our message and I’m not sure he is being clear in this at all. Bacon bits on a salad? Surely we can be firm and explain to someone “no bacon bits”, turkey on thanksgiving? no way is that ok:

    Dr. Greger: “Everything in moderation” may be a truer statement than some people realize. Moderate changes in diet can leave diabetics with moderate blindness, moderate kidney failure, moderate amputations—maybe just a few toes or something. Moderation in all things is not necessarily a good thing.” https://nutritionfacts.org/video/how-not-to-die-from-diabetes/

    Here’s another great one “we can’t just have a bowl of berries in the morning to meet our minimum daily antioxidant needs, and call it a day. “[E]ach and every meal” should contain high-antioxidant foods, which, if you remember, means plants. “[A]ntioxidant-rich foods originate from the plant kingdom.” This is due to the thousands of natural antioxidant compounds found naturally in plant foods.” https://nutritionfacts.org/video/antioxidant-rich-foods-with-every-meal/ He clearly says “every meal should” and there’s another video like this where he says every meal, I just can’t find it right now.

    Here you can see where Dr. Greger quotes Dr. Esselstyn “If the coronary artery disease epidemic is seen as a raging fire, and cholesterol and fats as the fuels, the AHA [American Heart Association] has merely recommended cutting the flow of fuel. The only tenable solution is to cut off the fuel supply altogether—by reducing cholesterol levels to those proven to prevent coronary artery disease.” In “Moderation Kills” https://nutritionfacts.org/2018/01/30/moderation-kills/

    This is another good one “it is nevertheless scientifically and ethically imperative to inform the public what constitutes an optimal diet. We must tell the public the truth about what is best for their health, and let them decide their degree of compliance.” “Just Give It to Me Straight, Doc” doesn’t mean half ass: https://nutritionfacts.org/video/optimal-diet-just-give-it-to-me-straight-doc/

    It’s late, I have to get some sleep and I think you need to watch more Dr. Greger videos 😉

  • 20101
    I think Taiwan also needs this food label system, it’s much more easier to consumers to know what they’re eating. The system can help people who are gaining muscles or getting rid of fat as well.

  • This is a wonderful way to eat, and also help kids eat! It is a European concept (they use this instead of “My Plate. gov”)…. Dr. Sears adapted it and uses it as well with his L.E.A.N. Start program. I guess maybe this is HIS interpretation of the already-existent traffic light eating system.

  • MYCOTOXINS have a negative health effects on your brain and immune system-inflammation. MYCOTOXINS are found in beans, corn, chocolate, nuts, grains and coffee and would make a great video! Also Mycotoxins from mold in your house causes compromised immune system and can cause death.

  • 20103
    I think this is a good idea to give those labels colors. Even you are a lazy person, you can easily choose the food which suits you the most.

  • 20123
    After watching this video, Barry is worried about his weight and he wants to use this label,traffic lights label, to let him avoid getting diabetes. But I don’t see this labels on Taiwanese food package whether this food is healthy or not.

  • I absolutely loved this video like virtually all your videos! But if you made a lengthy, strictly green light video that explains everything scientifically proven to specifically benefit a vegan diet (me and most of all my jewish friends and family are) I and them would be extremely indebted to you, more so than we already are for your valuable information. I of coarse would forward it to my multiple rabbinic authorities I know in the holy land as well as my chabad since most of them value a plant based diet, as I very much do, much more than your average vegan Jew.

  • Doctor, I know the traffic light system is what You like to establish. But don’t take credit for this plan that was pioneered by Nathan Pritikin in His wonderful 1983 book “The Pritikin Promise.” That’s plagiarism. CMJ

  • Jammer dat men nog steeds denkt dat (verzadigd)vet en choelsterol (van goede kwaliteit) dik maakt en ongezond is….
    Zoek op internet maar eens naar “Het faillisement van de verzadigde vet hypothese”.
    Maakt dat soort achterhaalde fabeltjes keihard met de grond gelijk.

  • finde das system gut aber ich bin auch der meinung, dass man sich heutzutage einfach die zeit nehmen MUSS, sich die nährwertangaben auf der rückseite anzusehen und dann zu entscheiden was man kauft und was nicht dafür muss man kein ernährungswissenschaftler sein.

  • Of course a channel that promotes a plant-based diet is going to have a large vegan audience. Not everything is about health. There is also ethical, environmental, and even human rights issues with supporting the animal agriculture industry.
