I can't speak the for Maria and Jim I'm waiting on her blog post as much as everyone else, I do believe she's more deeply into the Keto end of the spectrum but that's a subjective eval and I'm very curious.
But I was the one that gave Larry the "hey did you get chubby too" email; and then recommended a book I had been handed only 3 weeks earlier. The Book is "Primal Endurance"; it's worth a read if nothing more than to broaden you scope of ideas. I went with the audio version and the first chapter of "lists" about killed me but I soldiered on and I've been through it twice.
I'm going to do the same thing I do every time I talk about books..... Read the book if you think you want to try this; reading it will tell give you the "is this for me yes or no answer." You can't do cliffs notes, or ratz notes, You shouldn't dabble in this stuff based on just summaries from the rest of us. Once you have read the book or the same articles then we have a basis to discuss and compare notes. I also hate doing these things in a vacuum, in our case we have me (I'll try anything guy with stupid will power), My wife (the scientific proof person), and Larry (the how the heck can that work engineer / think it to death guy) Pretty good combo to give it a go and compare notes.
When you distill it down: Primal Endurance is based on Primal-BluePrint which is found over at
http://www.marksdailyapple.com. Primal-BluePrint over simplified is Paleo with the Dairy added back in. Building on that, Primal Endurance is BluePrint adjusted for Endurance athletes. OR even shorter Primal Endurance is a more realistic maintainable version of Paleo with enough good carbs for Endurance Athletics to succeed.
The book is preachy and they are of course trying to sell you on stuff and their life-aids to make it easier to do. You have to relax and just roll with that crap. For Larry his religious beliefs are basically in direct conflict with the books "spin," that doesn't make the approach wrong it just means you have focus on the core material as with all these sorts of things and push past the perspectives that really don't matter. I don't really care why my personal body doesn't handle sugar and grains well; I've been able to test that and verify it; I know it to be valid for me and therefore this diet aligns for me personally. Was I built that way? did I evolve that way? Sorry doesn't matter, don't care, too busy, 5 kids, 14 bikes, no time.
Consider this the disclaimer: if Larry can set aside the preachy part of the book to get at the core material, most people should be able to; and if you need to vent about that part email me and Larry and we'll listen and challenge you to adapt and move past. I have never had to like someone to learn from them.
So.... The carbs in the diet come from the best sources, so you are basically dropping Grains and Grain derivatives, Sugars, and things in the Potato and Rice families. So for me the killers I had to say good by to are French Fries, Ice Cream, Beer and Breads... The rest of it Pasta, Rice, sugar I really don't miss. The wife has been working hard to create alternatives and we are doing well example: we have an awesome hamburger bun alternatives figured out. We have a pinterest board of recipes if people are interested in recipes that have been tested and will be made again. The good news is I can drink Mead this summer which frankly is better than beer; and Whisky might have been on the menu in Vegas last week.. .... Six days no riding; in Las Vegas; I gained 0.8 lbs and I was on the diet without a problem and ummmm drinking a little bit at the nightly meetings.
Ok back to the summary over simplification (read the book).
Transition to the diet occurs at 50g-100g per day that lasts two weeks.
Weight loss can continue at 50g-100g per day based on individual needs
Maintenance happens at 125g-150g per day
If you get rid of Sugar and Grain, 150g of carbs per day is a lot of food even with super foods. However, the first 2 weeks SUCKS ROCKS; if you metabolism is very use to PROCESSED sugar and REFINED grains (not the good stuff Lee and the Vegans eat, but the crap the rest of us eat too much of) you are going to suffer even with the good carbs going in (The book would call you Metabolically compromised, I would call you Americanized) ... You can eat some strawberries and you'll feel better but it's going to be short periods of time. You don't like to suffer? Sorry perhaps go elsewhere. The wife and I got through the worst of it by taking some things from race strategy; we upped our amino acid intake to 12 hour race levels; you can get them from a lot of places we just used Hammer Nutritions race Amino Formula based on past good results on 120+ mile rides; that and we supplemented with extra L-Carnitine as it has helped me burn fast easier in the past, dose with breakfast, lunch and with dinner. With the amino level jacked up our Brains didn't push us to crave the sugars near as much (brain goes, ok body "I have what I need; don't care if you are starving," brains too stupid to know there is a fridge full of food and starving isn't going to happen); ((insert bunch of reading about the central governor theory here)). If we missed the dose you could see it in the other person's mood. After two weeks that wasn't needed (yeah it was a crutch big time should not be needed but, after our big house move in October we where seriously in a bad diet place). If our cravings for sweets did drive us nuts we could eat a piece of unsweetened dark bakers chocolate; and that would solve the problem every time, but you can only go to that bitter bank so often.
After two weeks all the suffrage was gone and we both felt better by far than before we started. If I recall correctly Larry stopped bitching about headaches around day 12; he had the advantage of starting later so I could console him that it was going to turn for the good and to hang in there, but I'll throw him under the bus he wasn't thrilled with the experience at all
.
There a lot of details around all this; but basically just like Atkins, of old, there is a 2 week restrictive period to get the body switched over. What you do after that initial two weeks depends on what your goals are. You will eat far healthier than Atkins and you will eat a lot of good carbs unless you twist the message of the diet (people do that; don't be that person, you probably know someone who did Atkins and tried to live perpetually on bacon; that sort of diet is coming to and "end" one way or another). I could post pictures of out meals but that's so weird but, you'd think we eat pretty good and tasty foods if I did.
For the athletic side of the equation, the transition to this approach is a lot of LONG SLOW mileage and requires getting back into the heart rate monitors (read the book, after that listen to the podcast (warning podcast has good episodes and then preachy crap ones; skip the preachy ones and get to the ones where they interview successful people)). The general guide is to train for 8-16 weeks at 180-age bpm on your heart rate (This is a reliable threshold, erring on the low side on purpose). This is really hard to do; it took me weeks and weeks of riding very carefully to get stay in those low ranges my ego as it relates to "watts" was not happy.
This BPM ensures that you burn fat during the workout and that you burn fat AFTER the workout. If you get out of your aerobic range then you dip into glycogen and that lowers the training affect. When I started this 125 watts would putt me on the nut and I could only keep my HR low enough at low cadence below 85 sometime as low at 70 rpm.... After 10 weeks; I can cruise along at 150 watts and 128bpms at 95 rpm. It was a slow process. Sometimes I had to go way slower than I wanted to. Gradually my aerobic base started to build and I could go longer and faster while staying out of my glycogen burning mode. The massive amounts of going slow was supplemented with an occasional go fast ride but never more than 1 per week. All my rides are on strava for people that want to go look at them; I have 4 more weeks of going slow. The results thus far tell me I'm going to see it through.
So I'm getting way to far into the weeds here are the results. 2 days after returning from 4 days in Las Vegas on business (both the wife and I went for work)
1) 6 days no riding.
2) I gained < 1 lb
3) Wife gained nothing.
4) Wife FTP tested today at 161watts (she was 120 end of February start of diet)
5) I FTP tested today at 210watts (I was 180 end of February start of diet)
6) I've lost 2 lbs per week I am 172lbs started around 208lbs, targeting 160lb.
7) We don't state the wife's weight loss but she's less than high school weight (carried 4 kids to term) she needs a new wardrobe, she was thin by U.S. standards before; now she's athletic fit and lean muscle.
8) I've done a few outdoor rides now. I do drink more water; but no fuel. I've ridden with a friend on DF that puts out 280watts in his sleep. I went out and was able to make him very unhappy on a 2 hour ride where I cruz-ed at the front at my 150 aerobic watts while he hammer out 200; and then I got to crush him going up hill when going 350 was trivial for the duration of the climb for me. I might have sold a V20 in that process as well. I'm stronger than last year and I'm still in my base phase. That part is very encouraging.
As for Larry..... well Calvins was a B-Tapper, he'll be humble but I have the data files, he went into the event with fatigue; and some life stress. you saw the results; the diet didn't hurt him; and yeah he used carbs for fuel; and that doesn't violate the plan or the approach; it's accepted as necessary for ultra endurance. He just didn't' need carbs to fuel the entire effort.
This not meant to be the facts; it's just a summary of how confused my brain has it when I cite it back via keyboard; read the book; pick a study; or whatever. If you go with the P.E. approach you are welcome to PM me for support and to ask the "did this happen to you" questions. I'm happy to answer those but I'm not sure the open forums is a comfortable place for that for a lot of people (unless you are an assusie).
Back to Hardy's question:
1) Run around on fat for a long as possible without feeling like crap (adapted diet),
2) Increase the speeds you can get from Fat and a Lower heart rated (adapted training).
3) When it's time to drop the hammer due to 1 and 2 you have more Glycogen left to really blast the effort (use fat + glycogen)
4) If it's race day; grab those easy access carbs use them like weapon; use them smart; and you won't need nearly the volume of anyone else.
Like any crappy scientific study with have a sample size of 3 people that are having good results. If we lump in Jim and Maria that's 5.
((I'll stop now as it will take 5 re-reads over two days to fixes all the typos that are probably lurking in this one))
