In Episode 228, I sit down with Dr Stuart Phillips and Dr Christopher Gardner for a discourse on how much protein we really need.

theproof.com/podcast/
There is ongoing conversation about protein requirements across all eating patterns, with this contentious topic often sparking debate on social media. With protein regularly used as a marketing tool or to push an agenda, many online sources are diluted and separated from the evidence. Dr Gardner and Dr Phillips - both from different fields - have recently taken varying stances on protein, engaging in a Twitter dialogue. In this episode, we bring both of their informed perspectives to the table, and ask: how much do their opinions really differ?
Christopher Gardner, PhD is the Rehnborg Farquhar Professor of Medicine at Stanford, the Director of Stanford Prevention Research Center’s (SPRC) Nutrition Studies Group, and the Director of the SPRC Postdoctoral Research Fellow Training Program. For the past decade, his primary research focus has been RCT in nutrition, and in recent years his focus has shifted to food systems as a whole and helping individuals make healthful improvements through motivators including social justice and animal rights, and their relationship with food.
Professor Stuart Phillips is a Tier 1 Canada Research Chair in Skeletal Muscle Health in Aging, and a Professor in Kinesiology and Graduate Faculty in the School of Medicine at McMaster University. With a prolific academic career and research focused on the impact of nutrition and exercise, Dr Phillips is highly established and widely respected in his field.
In this episode we consider a range of factors that may affect protein needs, with both guests offering their own insights. We discuss nitrogen balance, lack of protein vs lack of exercise, and protein restriction. We also cover protein quality, satiety, and environmental considerations. Recommended daily intake (RDA) is a key factor in this conversation, with discussion points including its definition, the studies used to inform it, and whether you should eat above it.
Specifically, we discuss:
0:00 Intro
3:13 Analyzing the RDA for Protein
17:36 What is Optimal?
22:25 Dr. Gardner’s Approach to Protein
33:38 Aging & Muscle Preservation
38:32 How much is TOO much?
44:21 Plant Protein
56:54 Environmental Concerns
1:01:52 Satiety
1:07:24 Outro
Whether you’re torn on protein requirements or convinced on a certain viewpoint, this conversation will make for an interesting listen. I hope you learn something and feel more confident in your views.

Thank you Simon for continuing to ask the hard questions and for straddling the line between a healthy diet for longevity, health span and performance, etc. I so appreciate your balanced approach to the plant-based diet and I will continue to turn to your work for my own education and nutrition coaching practice. I also love the “debate-type podcast you doing, and would be very interested in a discussion with you and Dr. Peter Attia as well as you with either Dr. Laymen or Dr. Gabriel Lyon

Keep in mind, on one of his papers, Dr. Stuart's author disclosure statement: "Stuart Phillips has received research funding, honoraria for speaking, and travel expenses from the US National Dairy Council, the National Cattlemen’s Beef Association and Dairy Farmers of Canada". He says there's some vague 'optimal' value we don't know above the RDA for vague reasons as to why it is needed. I've also heard him say in a video on Nutrition Made Simple that there's a lectin problem with plants, plants aren't as high quality, and that fiber inhibits the intake of some protein. So there's that.

Don Layman’s work has been funded by these groups as well. He tries to get NIH and other government grants for a decade and finally went to big food. Yet, his findings on Leucine threshold and protein synthesis remain strong. Just because a study has corporate funding should not be the sole reason it is questioned.

Everyone needs to listen to this!! These are the kinds of conversations I enjoy the most - calm, reasoned, views from both “sides”, and, shocker, they agree 95% of the time. Mainstream media, our egos, like the conflict, division, shaming, and fear-mongering because it gets clicks and sells. But the reality is that a lot of folks are converging on agreement over a lot of good things, like these 3, and splitting hairs over other less statistically significant things or as here, different ways of measuring something, and that barely gets airtime because it’s not as sexy lol. Thank you, Simon! 🙏🏼

This was clarifying. My dad(77), who is on several types of heart medication, walks about a half marathon regularly, and has better stamina than me, certainly doesn't have to worry about frailty and low protein intake. He eats roughly according to official recommendations. I agree with Gardner that it's probably the activity that causes the appetite and at his age, staying active is just even more important. When that's taken care of, protein intake follows. Philips is right that regulations for nursing homes should take higher protein needs into account. After all, people are there for a reason (and it's not merely age).

Interesting stuff! I did a low protein 80/10/10 type of diet years ago after reading the Starch Solution. Lost a ton of weight, slept like a baby, and was almost never hungry. Certainly lost some muscle and strength, but I felt so good otherwise I didn't care. Something really interesting that happened though was that some skin tags I had completely disappeared. In fact my skin in general cleared up quite a bit. Don't know if that was just a product of weight loss, but I've since gone through multiple weight fluctuations, and I swear you can gauge how much protein I'm eating based on how red my skin is. Don't know if it's some mild inborn allergy or if something else is going on, but anyone who knew me during that time will tell you I was never more confident with my shirt off. I did it for three years before getting bored and wanting to get back into the gym. It taught me a lot about the importance of calorie density and the role of fiber and resistant starches in satiety. I think protein matters, but not nearly as much as a lot of people think, especially if you're not hyper-focused on lean mass gain.

I wish they had looked at protein more from a muscle retention aspect, both in weight loss and ageing. Dr. Gardner doesn't address that; his focus is on weight and calories, not gaining or keeping muscle. Dr. Phillips has addressed this issue for years, but didn't seem to bring it up for discussion as much as I'd have wished. I'd love to see Dr. Gardner and Don Layman together (or Dr. Layman and Valter Longo)

Howdy, I have listened to these guys for a while now. Everything is very informative and easy going. My issue is that I started weighing everything for the last 2 months and putting in to My Fitness Pal to keep track and I only had 1 day in 60 where I even got 1g per kg. I feel I eat loads of protein but am always low. Don't know where to go from here other than a protein drink, but there are so many to choose from. I have also been trying to lose 50 kg and have only lowered my carbs so that I am losing 1kg per week. Really need a show on how to manage everything. Keep up the good work.

An interesting debate. I am a 66 year old vegan and recently I decided to up my protein intake as I was averaging 50g per day and weigh 55kg. I still find this hard and eat tofu and black bean or edaname pasta / quinoa every day to bump it up to around 100g. Sometimes prtein shakes. Plus more nuts than before. Initially I dropped my carbs to around 50g per day and was loosing weight even though my calorific intake was higher. I could not maintain the drop in carbs for long and now it is around 120 to 150 g per day. My weight has increased again but I am happy with that as a little fat and definitely more muscle protects bones.

Simon, great podcast as always. I have a suggestion: could you do a dedicated podcast to address protein requirements with true examples of meals for, say from their 50s or 60s on or whatever age seems most appropriate? Perhaps divided into male and female needs? I think there are too many of us in this boat. I am a 56F and sadly a failed WFPB eater - 5 years into WFPB ( and I do blame myself) I developed severe iron deficiency anemia, while I also lost quite a bit of muscle when I was also losing weight too that, frankly, I had no need to lose. I have never been a big eater and I am tall and thin by genetics.Of note, my doctor would have never suspected muscle loss as I always" looked" so healthy, perfect cholesterol panel and perfect blood pressure even with a BMI of 17, so I think that the statement that doctors do not see protein deficiency is true only in the sense that there is no true marker or measurement to address the question of subtle chronic deficiency rather than the obvious cachexia of some ill people. I am eating more animal products now with my beans, but for the life of me I cannot really gain much muscle especially entering my very late perimenopause! Get your experts in !!

@@TheProofWithSimonHill Hi Simon, it's a long story (nagged by osteoarthritis, going plant base thinking to make it better- it did not- eventually hip surgery and slow recovery which I learned really you never do recover, so multiple reasons to have muscle loss) so my story likely is not reflecting the majority here. I do train now 3 1/2 a week and power walk 1-2 times a week. I do feel stronger but honestly I only started to feel better after multiple iron infusions. I still eat very healthy but I had to add 2-3 servings/week of meat/ fish / eggs/yogurt to my WFPB approach.I kind of fell for " just eat all the colors" and that was my mistake. I realize not everyone can do that but I had to become sick to wake up to this fact. When I actually started to count what I was eating in terms of calories ( 1500/day average) and proteins (30-40 gm as reference I am now up to 53kg- 169cm- at my lowest on WFPB I was 50 kg) it became apparent that I really was not taking in enough proteins. animal foods have a small volume so it is easier for me to keep up. I started some protein shakes now as I find it still hard to get 1.2-1.6gm/kg/day of proteins, but I have mixed feeling as they seem to me just another form of ultra processed foods. Anyway, I so appreciate your work, I think you are amazing! One day I hope to have a better approach to WFPB

doctors push calcium supplements & D3 for osteoporosis. some say calcium accumulates in arteries. take K2/D3 to send calcium to bones & teeth instead of arteries. increase dietary calcium. increase protein (at least 1 gm/kg) & add resistance training. "Indeed, more than 50% of elderly men and almost 70% of elderly women in the US are considered regular users of calcium supplements." "in fact, calcium intake from dietary sources does not seem to increase cardiovascular risk, while calcium supplements might raise CHD risk." -- from study: Calcium supplements: Good for the bone, bad for the heart?

Concerning land us, I have read that the best use of land to provide protein would not be just for plant agriculture but include providing grazing for dairy cows. I read Barbara Rolls's book decades ago and it did help when I turned the corner and committed to give up bingeing on sweets. I had already used her method at times, but bingeing is not about not being full from food, it's about an intense dopamine hit-not as strong by any means as drugs like heroin, but not about real hunger, either. So even though I was eating filling meals, I still binged on sweets just about every day and it got worse and worse. Eating real meals without sweets but usually with freggies and whole grain plus animal foods was key as much from a psychological side because I could tell myself I wasn't eating too little and didn't need that extra food when the urges came. Urges to binge on junk were more likely WHEN I WAS FULL. When I was really hungry, I wanted more savory, real food. It took quite awhile to wean myself off the insane amount of sugar I was ingesting.

I still think most people are going to be fine just eating healthy whole foods and not worrying too much about it, but I appreciate that there's a space within the plant-based community where we can challenge certain preconceptions that tend to be bandied about uncontested much of the time.

I am 66, I try for about 1.5 times the RDA (1.2 g / kg). Mostly plants, a little cheese. I weigh about 70 kg, so 1.2 * 70 = 84 g. For a comparison, roughly 15% on 2200 Cal = 82 g, so very similar. If I were trying to add some muscle, via a month or two of hard training, I would have no objection to supplementing that up to perhaps close to double the RDA (112 g) for that period of training.

I'm 60. I admittedly don't know too much about optimal protein intake, but I'm always looking at research and data. My IGF-1 reading was 220 from a recent blood test. While within the normal range, I want to try, and have no idea if I can do it, to get it to the mid 100's. For ages 50-65, based on a study I read (which I will link later, and yes, there are limitations) the recommended protein intake is 0.7-0.8g/kg if an animal based diet. After 65, up it to 1.0-1.2g/kg. Currently, 90% of my daily protein intake is plant based now, and typically constitutes about 25% of my diet. However, I still eat small portions of wild salmon and tuna 2-4x week so the IGF-1 still may be a concern. I ditched beef, chicken and turkey and will abstain until my IGF-1 lowers, if it ever does, or until I'm 65. I don't miss them at all. I resist train along with other strength exercises during the week, and feel and look good at about 60-70g of protein/day. Opinions welcome. Between the ages of 50-65 and eat a lot of meat?

Surely the “RDA” has to be dynamic. The dynamic is surely the intake of calories. 0.8 is a figure based on the 2000 cal intake per day. Now if I’m an Olympic swimmer in training I intake at least 4000 cals. So CLEARLY for repair and muscle development then I will need a dynamic of 10% protein on calories intake. 4000 cals intake @ 10% = 400 cals = 100 gms protein. As long as we use the 0.8 static RDA we will always have arguments beginning with athletes . Dynamise for physiological realities and we solve the problem: 10% protein on calories intake. Both Stu and Christopher’s points are valid.

You asked good questions Simon and I loved the friendly tone of the discussion. But I think the longevity issue was not properly addressed. It is not really Chris Gardner's field so he was not well placed to counter Stuart's comments. The mechanisms by which protein restriction (particularly methionine restriction) extend lifespan (and improve health span) are many and they are via nutrient sensing pathways that are conserved across all species, not just interbred mice. Luigi Fontana or Valter Longo could speak to this.

So glad to hear Dr. Gardner dismiss the myth of plant protein not having all essential amino acids. Just today I was reading Emeran Mayer's recent newsletter, and his health writer in an article on protein needs espoused the myth! I learned about Emeran from Dr. B and so it surprises me to hear this incorrect info coming from him. Simon, I teach WFPB nutrition to older folks. My question is this: If someone older, let's say 70, my age, eats a diverse WFPB diet, walks and does resistance, can balance on one foot for more than 30-60 seconds, can lift a 30 pound barbell over her head, can push 90 pounds on a leg machine, is there any reason to think this person has sarcopenia and is need of a higher protein level? What would you say an appropriate protein level is for the 70 year old I just described? This person is not an athletic competitor, just trying to be fit and maintain a healthy body and normal BMI. I love your work Simon and am grateful for all that you do to educate the public. Thank you ever so much!!!!!!!!!!!!!!!!!!!!!!!!! 🥰

Maybe the best conclusion is simply that if you eat real food, plant and animal based, you will naturally eat healthy and macronutrient ratios will naturally be whatever they need to be for you. I think it's fair to assume that evolution has optimized our food choices the best possible, IN the context of real food. But the artificial foods we produce, they confuse us. They pretend to be something that they're not. And as a result, we eat more of them. Processed foods are engineered (literally) to bypass our signalling system so that we eat more of them. This is even true for so called "healthy" processed foods. Perhaps not intentionally, but that's what processed foods do. They confuse our bodies.

@@TheProofWithSimonHill Yeah that's possible. :). I believe that the elderly play (played?) a necessary part in the survival of our species. Becoming (great)grandparents wasn't rare. But I think it's important to realize that nutritional needs seem to change with age. That's my experience at least and I see it in all elderly people I know/knew. "I can't eat that anymore" is a pretty standard phrase. When you look at what the very healthy elderly eat, what you find is that they're not exactly following the guidelines. But they do eat real foods and very little processed food. Not a carnivore diet or a vegan diet, but something that's quite in the middle. It's not SAD either. High in animal foods but also high in plant based foods. But most importantly,.. they're eating enough. Frail elderly's main problem seems to be that they don't eat enough. I don't believe that longevity requires special foods. Just real food and enough of it is all that is needed.

I haven't watched this yet but I'm glad to see it posted. I just listened to Peter Attia with Dr. Don Layman which was a great discussion, but all the time I kept wishing you were there too! As a 57 yr old woman with hypothyroid, who is trying to rebuild lost muscle mass through resistance training, I'm beginning to question my choices. I've been vegan for almost 10 years and I really fell for the "don't worry about protein" that's touted in the WFPB world. I'm beginning to now believe it is more important, especially being female and my age and hearing how muscle mass is so important or health and longevity. How do I get my leucine? And how do I get enough protein while not eating too many calories? I've got about 10 or so pounds I cannot shift. It would be so much easier if I didn't care about the animals and our environment. But how do I stick to my ethical values and maintain health that I'm as close to thriving as possible. Okay, ramble over. Going to watch this episode and hope I can find reassurance that being vegan and thriving is indeed truly possible, even into old age, just like they all said it is ;) Thanks for all you do! EDIT: back after watching/listening to this just say thank you! Brilliant discussion and I feel much better now :)

Simon your guests and discussions have been quite good. I am a medical oncologist. My bias is that I am a whole food plant centered practioner I eat whole foods most of the time plants I am 95% adherent. I am concerned about the link of cancers in food and most of the links are to excessive calories or animal products. My questions if any guests can answer them are that it appears that several amino acids found in higher quantities in animal proteins are linked to cancer promotion such as methionine, lysine, leucine, glycine, serine see Dr Oliver Maddox work, Dr T Campbell and several others. Could limiting consumption of these prevent cancer? There appears to be an ideal amount of most nutrients. There are some who are studying chemical or dietary restriction of some of these amino acids for cancer treatment. I wonder if the lower ratios of some of these amino acids in plants explains why in several population studies there are trends for less cancer with more plant over animal protein consumption? Could it be that the lower quality of plant proteins helps in ideally regulating growth as to not promote cancer? Can animal proteins be likenend as the processed sugar of protein and do our bodies benefit from the so called poor quality properties of plant based proteins which take longer to process and have less ratios of some essential amino acids does this deficiency clamp down on unregulated growth of unwated cells less than desired cells? Do these amino acid deficienies aid in beneficial autophagy to limit cancer causing cells? I assume some day we will show that if you eat the right quanity of animal products consumed in the right way meaning avoiding processing and certain cooking methods then animal products may be ok in limited amounts but that for overall health we are best eating moslty whole food plants.

As a Physical Construction "Building Block" Nutrient, it makes no sense to apportion your Protein Intakes based on any % of Calories. There is a minimum amount (The RDA) and an Optimum amount Protein Intake...and an Optimal MIX of Amino Acids (especially Leucine - where there's a 2.5g TRIGGER DOSE for muscle rebuilding). Optimization is ~ 200% of the RDA...maybe a bit higher than that for the elderly.

I still don't understand how Christopher Gardner can say that we eat enough proteins, and recommend that we stop worrying about it. As I am doing exercise to build up muscle mass, I am aiming at 1,6 g/kg per day, which means 115 g per day. Divided by three meals, it's 38 g per meal. Considering that vegetables have very low amounts of proteins, and that rice, pasta, tofu or legumes all have significantly less of the protein amount that can be found in meat and cheese, I don't see how I could get to that daily target without consuming 1-2 portions of animal proteins per day. You'd have to consume lots of nuts, or a really significant amount of starch-rich food such as pasta, which would spike your glucose levels. Let's say that in one meal I consume a moderate amount of rice (65g) and a good amount of vegetables (200 g), that makes about 10 g of protein. I am still missing 28 g. I would have to eat 400 g of beans in a single meal to get to my target of 38g.

And animal protein digested to amino acids is a nasty chemical process going on in the gut. Try to find a plant even fruit that has no amino acids. Amino acids are everywhere other than in highly processed foods.

I have zero problems with muscle recovery post-workout, zero problems maintaining my mass/body weight. I've been vegan 8 years.

You would have to eat in excess of 2,000 calories daily and unless you're an athlete or a naturally very tall/large mass person, you simply don't need more than the RDA of 67 grams of protein, even with it being all plants. I don't need it and I have tracked and figured out all of my meal recipe macros years ago. So, please stop with the high protein myth. You don't need more than the very generous RDA of 67 grams of protein on AVERAGE. I literally go some days with only 50 grams of protein in an entire day and I'm not sick or thin or weak.

People also need to be eating sufficient energy calories in order to not use their protein for energy. Otherwise the amount of protein needed seems fairly low, with around the RDA being more than sufficient for almost everyone.
