It is probably true that everyone knows a person that is either obese, diabetic or pre-diabetic. That is a very sad statement of the health or our nation and the world. The epidemic of obese and diabetic people has exploded in the last 40 years even though many have done their best to “do their best” by exercising and eating according to the Standard American Diet recommendations of low-fat high carbohydrate. Check out this video: BBC Panorama: “Diabetes: The Hidden Killer” (2016). People are working hard on their diet and exercise, but they are not succeeding. Why? Denise Minger has an excellent book on the subject: “Death By Food Pyramid: How Shoddy Science, Sketchy Politics and Shady Special Interests Have Ruined our Health,” (2014).
I started taking a closer look at my own health and fitness back in 2013 after reading Prof. Tim Noakes website “Real Meal Revolution”. Prof. Noakes is a well known expert in running and exercise science and nutrition having written the well known books: “The Lore of Running,” and “Waterlogged.” Both of which I highly recommend. There is one caveat, though, as Prof. Noakes will tell you to ignore the high-carbohydrate nutrition information in the Lore of Running, as he now is convinced, and the science is supporting, low carbohydrate diets for weight loss, health, and even endurance sports performance. (see the books by Volek and Phinney: “The Art and Science of Low Carbohydrate Living” and “The Art and Science of Low Carb Performance”). More references are listed on our nutrition page. In August of 2013 I eased into a low carbohydrate lifestyle and since 2015 have been eating a very low carbohydrate, moderate protein, optimal diet consisting of less than 30 grams of carbohydrates per day, protein to support lean body mass, and good fats to satiety. The key is to eat no added sugars or high sugar foods, no grains and no vegetable oils, avoiding processed foods as much as possible.
What has been the result? To keep it simple… weight loss without hours of cardio. More importantly my annual physicals show lower heart rate, lower blood pressure, lower blood glucose, and a much healthier liver. Healthy, Happy, and Medication-Free. In fact, LCHF was the standard of care for obesity and high blood sugar before insulin was discovered.
So if you struggle with weight, study the Low Carbohydrate “way of eating” in the references listed and on the web. Then try it out for yourself. It is not a sacrifice diet, since calories are not the focus, and thus it is easy to make into your normal lifestyle. What can be easier than eating eggs, meats and leafy vegetables.
Here is an easy to read online ebook: “Ultimate Diabetes Control On Low Carb High Fat (LCHF) Diet” to get you started on LCHF. More later.
More reasons to focus on building lean body mass, not losing weight and fat per se. The health benefits of maintaining and improving your muscle mass are many… watch this video and see what I mean:

You may be aware that I have been on a Low-Carb, High Fat (LCHF) eating plan since last September and although I have not been very public with my results, I feel that this is the best way-of-eating for me. What is LCHF? It is where you get most of your calories from fats and the least from carbs. Typically your total calories are from 75% fats and saturated fats, 15% protein and 10% carbs. On this plan I have maintained my weight at the lower end (about 144 lb.) of the last 15-years range (140 -160) without spending all my time running or riding. In fact, I took the fall and winter off from training, only doing small workouts and some weights. Those of you that ride with me on Tuesday night know that I am not as strong climbing, but my overall average speeds are not bad for not training, and I have good endurance. Since I am now training for the Army 10-mile run race in October, I have been even more interested in how well I can perform on a LCHF diet.
I recently read a book on this subject — “The Art and Science of Low Carbohydrate Performance” by Volek and Phinney, two doctors who have evaluated the performance of LCHF athletes. In this book they discuss that once an athlete becomes keto-adapted, that is where their primary source of energy comes from fat, their endurance levels will increase dramatically. We have about 2 hours of stored carbohydrate that can be used for energy in our bodies, but even the leanest person has more than twice that amount stored in fat. But that fat is not available unless you are keto-adapted.
I came across a blog post from Sami Inkinen, an elite triathlete that sparked my interest. It is an experiment of 1, but quite controlled and he has very interesting results. He has measured the type and amount of energy used during controlled tests using the same equipment 3 time while going from a high carb diet to a LCHF diet. On the first test, he was eating a high-carb diet and guess what…. he has about 2 hours of carbs available and even though he had done hours of training in his “fat burning zone” he could not exceed 200 calories per hour from fat-burning at race efforts. Hence he would run out of energy once his carb stores were gone. A year later he did a second test on a moderate-carb/moderate-fat diet and his fat-burning numbers increased significantly, to 400 calories per hour at the same race effort. Finally, he performed a third test on a LCHF diet with the same parameters and increased his fat burning ability to 600- 750 calories per hour. The chart says it all. At 300W his bonk-time went from 2 hours to 5 hours! Interested? I am. I would love to see what happens with elite athletes such as marathoners and pro-cyclist if they were to go low-carb. I’ll let you know how my “experiment of 1” goes…
The USDA “Food Pyramid” has been around for 21 years, based on the dietary recommendations of the late 1950’s and official recommendations from the USDA in 1977. But data shows that the population of the world is the most obese that it has ever been. Seems that the low fat diet plan is not working (see the chart below), doesn’t it? Have you ever wondered why our grandparents ate all the bad stuff but weren’t obese? I did. As it turns out, there is a lot of new research that says they were right and that the low-fat, low cholesterol, and no saturated fat diet is actually causing the obesity epidemic along with several other modern problems.
My grandmother was a great cook, not a five-star restaurant chef, but she made foods that we all enjoyed and were better than you can find in any restaurant these days. Why? Because she used what she had, all natural foods including fish and game meats that my grandfather hunted, cooked in butter and lard. Lard? Yep. She made the best fried (in-lard) fish with corn-meal batter that I have ever had. Hands down! When her freezer got too full of fish, she would have a fish-fry and invite all the family and friends.
One of my favorite memories of her is the Thanksgiving dinners, where she would make each person’s favorite dish. All at the same time and all excellent. Sometimes for 11+ family members who came for the dinner. You would have thought that our family would be all overweight and in bad health from all that tasty, high-fat food. But that was not the case. My best description of my family’s diet philosophy was “everything is ok, just in moderation.” It was high in everything, low in nothing and all made from scratch. We hadn’t yet heard of the food pyramid. As it turns out, there is now a lot of good scientific research to say that the food pyramid is upside down. In this and later blog posts, I’ll explain.
I’ve been a follower of Dr. Tim Noake’s (University of Cape Town professor of exercise and sports physiology) books and writings for a couple of years now. Dr. Noakes is the author of several books that challenge the general notions and commercialized hype that rules the sports world. See the “Lore of Running” and “Waterlogged” which I have discussed before. His research into human performance and physiology is very well respected. He has debunked several widely-accepted ideas including the idea that you must drink to excess (promoted by the sports-drink industry) to be able to perform well in endurance events.
His latest research push is into the impact and efficacy of the low-fat dietary recommendations that were introduced in 1977 which promoted the following (from www.health.gov/dietaryguidelines): Increase carbohydrate intake to 55 to 60 percent of calories while decreasing dietary fat intake to no more than 30 percent of calories, with a reduction in intake of saturated fat, and recommended approximately equivalent distributions among saturated, polyunsaturated, and monounsaturated fats to meet the 30 percent target. They also recommended to decrease cholesterol intake to 300 mg per day, sugar intake to 15 percent of calories, and to decrease salt intake to 3 g per day.
In 1992 the USDA published the now famous “Food Pyramid” seen to the left. These recommendations have been adopted around the world and the words “low-fat” are on everything in the grocery store from cookies to yogurt to salad dressings. The result was the demonizing of several common foods including butter, lard, eggs, and full-fat dairy products. The push was towards grains, legumes, fruits and vegetables. Butter and lard were replaced with margarine (read: trans-fat), vegetable oils and polyunsaturated fats. Eggs and bacon were out. Lean turkey was in. Much of our food supply became wheat and corn-based because grains were subsidized by the USDA and therefore cheap and plentiful. Even the livestock are fed corn. Every product on the store shelf became labeled as low-fat and grain-based. Try to buy a non-low fat yogurt in your grocery store, there are one or two containers among the 100’s of low fat yogurts (which all have added sugar, by the way). Most low-fat products have added sugar to make them palatable, often in the form of the very cheap but very bad High Fructose Corn Syrup (HFCS).
Dr. Noakes became interested in the low fat vs low-carbohydrate diet issue when his own weight and pre-diabetic condition became a problem. Although he has run more than 70 marathons, as he aged he was unable to control his weight. In this article he explains his justification for moving to a Low-Carbohydrate High Fat (LCHF) diet. He is carbohydrate-resistant which makes him unable to tolerate high carbohydrate diet. It is ironice that LCHF was the recommended method of losing weight (called “Banting” after William Banting) from the 1860’s to 1959, when it was replaced by the Low-Fat High Carbohydrate (LFHC), so called “Heart Healthy” diet (due to Ancel Keys’ flawed analysis that led to the claim that cholesterol causes heart disease).
So how have the low-fat, low cholesterol, high carbohydrate recommendations worked out? A very compelling article summarizes the correlation and reasons why the “Low Fat War” was a mistake. The correlation is uncanny, but that is not proof. Recent scientific studies have shown that the Low-Fat guidelines are indeed wrong. In addition, many health problems that are epidemic these days are being attributed to the HCLF lifestyle.
I have never had a big problem with weight, but have always been annoyed that my weight would fluctuate 10 lbs (a lot on my small frame) when I stepped back from intensive training. The other issue is that no matter how many miles I would ride or run, I never seemed to lose that last bit of fat around my middle. In mid-September I decided to try reducing carbs in my diet and to keep track of the results. Studies have shown that weight can be easily maintained on 100-150 g/day and reduced on 50-100 g/day without restricting calories drastically. Going less than 50 g/day will make losing weight easy. Check out authoritynutrition.com‘s articles for good advice on this subject. In the US, many individuals get 40% of their calories from sugar, and eat more than 600 g/day of carbs. No wonder we are an obese society. Studies have shown low-carb diets are better at reducing fat than low-fat diets.
Initially I just lowered the overall carb total, then after a couple of weeks I went to less than 150g/day. Initially, I was craving carbs, but then when I realized that I was having more motivation, less 10:00 AM sugar lows and cravings for cinnamon raisin bread I decided to get down to under 100 g/day of carbs. I have eliminated almost all breads, potatoes, pastas and other grain-based foods. Added sugar, honey and other forms of sugar are totally out. After a couple of weeks, the carb cravings went away and I actually was less hungry. Although this is not a scientific result, I have lost 5-6 lbs (~4% of starting weight) while eating more meats, eggs, cheese and generally higher fat foods. This is while at the same time not riding or running significantly since the end of September (my usual fall hiatus from training). In past years my weight would have been 7 to 8 lbs. higher during this time of year. So this year I am essentially 11-14 lbs lighter than last year when I took time off. I think that is very significant!
In future posts, I will talk about what my research into the literature on the LCHF lifestyle has found including the health benefits. I will cover sugar, grains, eating fat to lose fat and why a “calorie is not a calorie” among other topics. I think you will find it interesting and eye-opening. It has been for me.
The general public consensus is that we lose muscle mass (size and strength, too) as we age. But there are notable exceptions to the rule — athletes who have performed exceptionally well into their 70’s and even 80’s. See the World master’s rankings. For example, in the 2012 10K rankings list there are 38 runners age 60 to 85 that ran the 10K in less than 40 minutes, including the US runner, Nolan Shaheed (35:26 10K, 60-65 age group) who has age group records at several distances.
Well known triathlete coach Joe Friel just posted in his blog an article about maintaining muscle mass and the notion that we are destined to lose muscle. He reviews the latest studies that actually show little or no muscle mass loss is due to aging. What, you say? There are athletes that maintain muscle mass well into their 70’s, the key is that they work at it. See the photo from coach Joe Friel’s blog at the right. The middle muscle scan photo is a stark reminder that we are too sedentary in our lives. From sitting at our desks for 8-10 hours all day then watching TV for 3-4 hours at night. How many of us do 1-2 hours of strenuous activity each day, or even 30 minutes as recommended? Less than 3% of the US population according to some studies I have seen.
There’s a second aging/sedentary lifestyle issue here, not only does a sedentary lifestyle cause you to lose muscle mass, it also causes the loss of nerve control of the muscles. Older, sedentary people have less nerve connections to their muscles, thus can’t recruit the muscles they have.
Just another brick in the wall of information that says that we must keep moving, keep exercising, keep the intensity up, and just don’t sit around. Guess I’ve been right to keep that big commercial walk-behind mower for the last 20 years. I’ve always joked that it was my exercise program — 2-3 hours a week of walking at 3 MPH in tight circles.
Just Keep moving!
Questions for all the cyclists out there as the season winds down:
- How has your cycling year been?
- Did you have a great year?
- Did you meet your goals?
- What would you change?
I, like everyone sets goals for my cycling in the early season. Usually I get excited in January about the upcoming season and the thought of getting back out on the roads, racing and riding with the local groups as the weather improves. It also comes from the fact that I have rolled my workout intensity back in the fall and in January I’m looking to get back into serious workout mode again.
This year has been very good for me and I have ridden some very strong rides, Battenkill, Trooper Brinkerhoff races, the Harlem Valley Rail Ride and finally the latest 50-miler: the “Bike for Cancer Care” group ride in Kingston NY last Sunday. It is a group ride with no timing and not a race, but the course is good with what I would call moderate climbs, only one is categorized (cat-4, but short).
I started out with no warm-up and just sat in with the second group of riders that were working fairly well together and pace-lining on Hurley Mountain Rd., waiting for my cold leg muscles to warm up and my attitude to improve. Somewhere near the left turn at the south end onto Tongore Rd., I started feeling better and stronger, so decided to work at it a bit, instead of just riding. Time to check the ol’ legs out and see if they were ready. Who knows, maybe they are actually working? After the turn on Mill Dam Road the course gets more hilly and the pack broke up. Another rider (Bill) and I, broke away on the climb and descent to Rosendale. We eventually rode together, trading pulls with each other for the rest of the ride (about 40 miles), averaging in the low 20’s for most of the rest of the ride. Eventually we picked up two more riders that were dropped from the lead group and finished strong, averaging 20 MPH for the entire ride. A nice effort and really a surprise for me, since I was not motivated and had no plan to ride that hard at the start.
The net of this long discussion is that this year’s training has been quite good and the results show it, even though I have ridden less total miles this year than last year at this time. About 500 miles less and riding 3-4 days a week. I’m also stronger than at this time last year. How did I do it? Through focused, high intensity training for strength and speed, with longer rides for endurance. This is the training that the Big Ring Riding group has been doing all season with excellent results. We have done all types of intervals: high-intensity, short, long, sprint, tempo, threshold, VO2Max, hills and more hills. In addition, we also worked on pace-lines, criteriums, and time-trials, just for the fun of it.
Here’s my offer to cyclists in the area. There are a couple more weeks of Big Ring Riding evening training sessions left this season and I am opening up the rest of the season for free to anyone who wants to try it out, no strings attached. Come out and train with us on Monday and Wednesday nights at 5:30 pm starting tomorrow, 9/18. Sessions last 1 to 1-1/2 hours, typically. Send me a message on our contact page or via FB to reserve your spot and get the details.
According to the article in the Sept issue of Health magazine, “After a killer workout, hitting the gym again is probably the last thing on your mind. But… doing light exercise two days after a tough session is as effective as a massage for relieving aches.”
We all know that the soreness we feel is due to the tiny muscle tears that occur when we stress muscles to build muscle strength. Some light exercise a day or two after an intense one will increase your blood flow, promote healing and enable the muscles to move more easily.
The article calls out these mini workouts “to combat achiness”:
- Take a Walk – a 20 minute stroll at moderate pace around the neighborhood or on a treadmill.
- Hit the Pool – Swimming a few easy laps will warm up the body and boost circulation. And best of all – it’s super low impact so won’t jar your joints.
- Work Out Your Core – Balance, or core focused moves, like single leg squats or side planks improve blood flow, up overall fitness and still give whining muscles a break.
And when all else fails, I hear a day at the spa is a scientifically proven cure-all!
I have been leading group rides for two years now, a task that is sometimes referred to as “herding cats.” I really enjoy getting out there with the group, working those legs, talking about whatever comes to mind, dodging deer, cicadas and squirrels; and even sometimes, working really hard at keeping up with a very strong group.
Last Sunday’s Big Ring Riding sponsored group ride was set up for 48+ miles with some good hills in the middle. The weather was to be nice, so it looked like it would be a good day. I usually ride from my house to Rhinebeck for the start, stopping for a cappuccino and pastry on the way down, and last Sunday was to be no different. However, I got up feeling tired and disinterested, thought about skipping the ride down and driving (not the capp and pastry, though) but decided to get out the door on time and take it easy on the flattest route to Rhinebeck. A good group of seven riders showed up and we talked while getting ready to go.
Off we went west towards Rhinecliff, my legs still feeling fatigued and burning while going up the hill out of Rhinebeck. I settled in and let the more motivated riders lead. Once getting to Rhinecliff I signaled an unplanned right turn and took the group down to the Hudson River at the boat launch. Most of the riders had never been there or didn’t even know that there is a nice spot to take a break during a long ride, have a snack at the picnic tables or just enjoy the view of the lighthouse at the mouth of the Rondout. A big empty oil barge was rumbling south so we talked for a few minutes, marveled at the Great Blue Heron on the bank to the north, then headed back up the hill to the planned route.
Heading south is the rolling hills of Morton road which got the group moving and pushing the ups and downs. The pace picked up as we headed onto South Mill Rd. but another excursion opportunity came to me and we headed for another unplanned right turn down Wyndclyffe Court to take a look at the now falling down, but still architecturally phenomenal Wyndclyffe mansion. If you’ve never seen it, it is a huge brick house built in the 1850’s in the Norman style (according to wikipedia). The house has been abandoned since 1950’s and since the 1980’s has been crumbling, losing one tower and lots of brick. Per Bob Yasinac, the house was “built for Elizabeth Schermerhorn Jones, a relative by marriage to the wealthy Astor Family, and it is rumored she is the source of the old adage: keeping up with the Joneses.” Sad to see these glorious mansions crumble into the woods.
So back to the ride we went and headed south, back to Rte. 9 and then right onto Old Post Rd. and guess what, another excursion into Staatsburg for a ride by the Mills Mansion down to the river again. Staatsburgh is another of the Hudson River mansions, but this one is a NYS historical site and is very well maintained. I’ve spent a lot of time there with the Red Hook HS cross-country team running and watching the team compete every fall. The grounds are open and free, go through the mansion on one of the paid tours to see how the people lived in the gilded age.
Next we headed back up to the planned route and up the hill, across route 9 and onto the meat of the ride. By then my legs were into it, and my head was too. So off we went for a lot of climbing and a very nice 16+ mph average over the route with a great group. We stopped to look at the great vistas of the Millbrook Winery at the top of Ernest Rd., had a couple of very nice dirt roads, climbed the east side of Salisbury Turnpike and flew down the west side. Successful day of riding, I think!
My training rides are hard work, head down, focusing and pushing those pedals for the entire workout plan. The group rides are much different for me, much less focused on performance. It’s all about the group and the route. Although we do ride hard on these rides, I hope to make them fun for every rider, not just the strongest.
Sometimes it seems that all I need is to just take it easy and look around a bit to get my motivation back. We ride in an area that has great roads and is full of the hidden gems like Wyndclyffe that we go by all the time without seeing. Look around guys, there is more to riding than average pace and climb stats!
I have been a continual cramping machine since I started running in high school and continuing ever since. Mostly, it is the “charlie horse” cramp that occurs when stretching or sitting in a chair, but I also cramp on the long rides, usually after 50 to 60 miles of hard effort. The cramps will affect my calves, hamstrings, quadriceps and the abductor/adductor muscles. Generally any muscle used to spin those pedals on those long, hard efforts. I like everyone else always thought it was caused by low electrolytes in my system due to the long effort. In attempts or prevent cramping, I have swallowed electrolyte pills at regular intervals, drank lots of water, drank less water, drank electrolyte drinks, and tried many different things in an effort to prevent cramping, all unsuccessfully. So I’ve been reading up on the subject.
I found an article where Joe Uhan summarizes the state of the science concerning the true cause of cramping, see his blog entry “Cramping My Style.” Here is what I learned: Surprise…. the notion that salt, or the lack of salt causes cramping is based on a 100-year old scientifically-flawed study of British miners. As it turns out, there are no scientifically sound studies that link low electrolyte (or salt) levels to exercise-induced muscle cramping. One study (Schwellnus, Drew et al. 2011), found that no difference in hydration or blood sodium concentrations between crampers and non-crampers. So what is the cause? Nobody knows for sure, but one new theory is that it is a neuromuscular mechanism to shut down the muscles to protect the body from harm that might result from continuing to perform at a high level. This is part of the “Central Governor” theory proposed by Dr. Tim Noakes (Science of Sport) in his books the “Lore of Running” and “Waterlogged.”
Oddly enough, it has been found that tasting salt (or pickle juice) can stop cramping very quickly, too fast for the salt too have been absorbed into the blood stream. Hence the theory that it is the brain and the nervous system that controls the cramping response, not the electrolyte or water balance. Essentially fooling the brain into allowing you to continue cramp free.
Whatever you think, Joe Uhan’s blog shed some interesting light on the subject and even gives a list of things that we can do to reduce the occurrence of muscle cramps and to manage them when you get them. Most of the recommendations are not about training your muscles or taking supplements, they are training your brain to allow you to continue. Good advice to consider.
The Big Ring Riding group did 26 miles of paceline work last night!
How strong and confident are you when in the peloton? Practicing these skills with others on a regular basis will make you better able to stay in the peloton no matter how strong your legs are.
We worked on pulling, drafting in high winds, signalling, staying on the wheel of the rider ahead, what to do when you are on the back and getting dropped, and other skills.
Active.com has a nice list of paceline skills here.
How good are your skills?
