Dr. Pfaffenbach joined us to answer some questions about cholesterol and the link to carbohydrates (VERY helpful insight), and a very practical discussion with specific macro targets to lose weight and keep it off. Hope you enjoy it, and if so, rate the podcast and share the episode with your friends!

TLDR biology is not a math problem . If you can’t make it a lifestyle change, then it’s a diet and likely temporary. Even when you do make the lifestyle change it’s not going to be linear. Also be prepared to make adjustments when things aren’t working.
This has been one of the biggest changes for me. Learning when to fuel, how to fuel. Focusing on modulating my carbs, hitting my fiber goals, proper protein.
STOP FOCUSING ON DIETING, make small changes not exaggerated drastic changes. (Im looking at you 75 hard people)
Maybe I’m a dummy but I’m not sure that I came away with anything actionable
Like, what does “modulate carbohydrates” actually mean? How big should a caloric deficit be for weight loss? If I’m 180 lbs wanting to lose weight, do I eat for 175 lbs or 172 lbs, and how do I calculate what that means in actual food? What does a proper deficit look like? How do I know if it’s within range, and how do I know when to readjust. What apps are helpful for this? Why would I take photos of food? What do I do with this photo collage information? How long should one stay at each weight target before dropping lower? Weeks? Months? How do you know when to adjust?
Jonathan mentions he made “lifestyle changes over the last 9-10 weeks” that resulted in fat loss, but never explained what those changes were.
And poor Ryan - who is 185 lbs, trains 8 hours a week, and wants to be 150 lbs - was never mentioned again in the episode. What should Ryan actually do starting Monday?
Dr. Pfaffenbach tends to struggle with brevity when he’s on the show. Most people struggle when you put a microphone in front of them — it just goes to show the skills that @Jonathan has developed over the years. In this case it’s worse because he has so much to say and has to edit it down for us.
My takeaway was this:
Pick a next step weight not crazy far from your current weight. The example was 180lbs → 172lbs. Convert that weight to metric because science says fuck imperial units.
Eat 1.4 - 1.6x that kg value in protein a day.
Eat ~1x that kg value in fat a day.
Eat at least 120g of carbs a day (lol).
Whatever you have left you can use to generate a calorie deficit. Don’t go crazy.
I really enjoyed the pod. Kyle is great and always good value. One quibble though - g/kg for macro intakes and then every bodyweight measure was in pounds. I was driving so couldn’t do the conversions at the time.
The way I approach the modulating carbs thing is to look at my plan and what I have coming up. If i have 1 hr or less rides I eat my regular 120g carbs. If I have a longer/harder effort ride the next day i increase slightly (maybe i have a biscuit with my breakfast, french fries with my lunch ect). On the bike I fuel similarly, 1 hr or less easy? no extra carbs. hard but shorter effort? I have carbs before I get on. Long/hard ride? carb before and continue through the ride. when I am not actively stoke the fire, i stop dumping fuel in.
So right now i am sitting at work and have a simple 90 minute z21 ride after, I will eat a fiber forward, protein rich diet as appropriate. I will say no to the random extra carbs(donuts, pizza whatever). Ill eat something after work as i am changing into my ride clothes (probably a pop tart because they hit). After I ride ill have something with complex carbs and protein (today it will likely be a high fiber wrap with veggies and some chicken).
Basically, while we have static numbers for our protein and fat intake that is a ratio of our weight, carbs fluctuate according to what we are doing with them. and that is where we can make incremental changes that will bring a slight calorie deficit. emphasis on slight.
It’s funny when I began the season I thought to myself I’ll like to get to 165 lbs for cross season but didn’t go on a diet or anything. Just limited junk food.
Now I’m at 168 lbs and thinking how to hold at this weight, I don’t want to go below 165 lbs.
A topic not really covered in the podcast was body composition. Several years ago I wanted to get down to 155lbs (70.3 kg) from 165 lbs (74.8 kg). At my wife’s suggestion I decided to get a DEXA scan, which showed me at 8.4% body fat. I realized at that point that 155 was really out of reach for me, unless I lost some muscle mass. And, as I guy then my upper 50s, that didn’t seem like a great idea, so I adjusted my goals to just maintaining my weight.
Also, once you get a little older, the amount of grams of protein needed per day gets increased (according to some studies, at least, due to the increased difficulty for the body to absorb it) to 2.2 g per kg of desired weight, which thankfully translates to 1 g per pound, making the calculations much easier!!
I’d have to relisten but I’m fairly sure that it was discussed. He (Kyle) talked about how a person’s desired weight might be achievable (and I’m going from memory here) and a couple of examples he gave were big, dense bones and a large brain - relative to another person.
Does he mention anything about workout calories? Or is he simply talking about eating intuitively?
In my and I’m sure everyone else’s experience , there’s a difference between my total calories for the day on a 4 hour ride vs a 90 minute ride.(with or without intensity)
I listened to and then watched the podcast. I am not much wiser! Kyle is obviously hugely knowledgeable and a real enthusiast for his speciality but brevity is not his forte. It’s partly the fault of the medium which encourages open ended discussion and leaves questions forgotten and unanswered. Perhaps complex but hugely important topics like this should be scripted in some way, with headers, clear questions and answers, one flowing from the other as interviewer and interviewee do what they wanted to do here- to inform and educate a captive audience.
I kinda have to work to get the 1.1g fat per kg body weight after years of reaching for chicken breast, skim milk, egg whites with an eye to keep lipid numbers looking good. It’s not like I’m super low body fat at the moment anyway, so upping the fat seems like a good thing to try.
They did not mention workout calories or choosing a daily calorie allowance on which to lose weight. One has to fill in the blanks themselves there.
I typically use the Lose It! app and take their calorie recommendations for losing, for example, one pound per week. (There are, of course, a hundred of these kinds of apps.
For rides, I increase the daily calorie budget with 1/2 the kilojoules of the ride. I experimented with adding 100% of the KJs back to the daily budget and didn’t lose a pound.
Basically, one has to figure out how to run a calorie deficit by themselves. Dr. Kyle though has done like 5 of their podcasts so maybe things are elaborated upon in one of the others.
I suspect that is way too regimented and involves way too much counting for most people. I do recommend the free version of the Lose It app. It allows you track foods and calories and look at daily macros. One could use that with Dr. Kyle’s protein and fat targets.
