Question I’m Asking

What’s the best way to keep kids from losing their intrinsic motivation to exercise? How do we keep movement for movement’s sake?

  1. I know one way to get kids to keep exercising: allow poor children to participate in team sports. The pay to play system that has been in place for decades is certainly not helping.

  2. I believe I originally found this article in a weekly link love a while back, but the story has fascinated me ever since. It is called “ICELAND KNOWS HOW TO STOP TEEN SUBSTANCE ABUSE BUT THE REST OF THE WORLD ISN’T LISTENING”.

    Best part IMHO:
    State funding was increased for organised sport, music, art, dance and other clubs, to give kids alternative ways to feel part of a group, and to feel good, rather than through using alcohol and drugs, and kids from low-income families received help to take part. In Reykjavik, for instance, where more than a third of the country’s population lives, a Leisure Card gives families 35,000 krona (£250) per year per child to pay for recreational activities.

    Imagine if we could provide a leisure card to low income families in the US. It would not only get kids active, but it would stimulate the recreational economy wherever it is implemented.

    1. I loved that article. We all need to take note and apply it where we live.

  3. The killing of giant sequoias is so sad! Impressive but sad.

  4. If you’re chronically stressed, your dog could be too…that was really interesting. According to me, the best way is to keep kids from losing the motivation to exercise is allowing them to do the physical activity they like the most like a football game, basket ball or whatever. Physical activity is also an exercise. We can also lure them by saying, if you exercise, you are allowed to play 30 minutes more?. That’s what I do with my nephew.

  5. Getting kids to exercise is easy. Start them on a super expensive sport like gymnastics. They have no problem knocking themselves out for 20+ hours a week in the gym. And they think it’s fun!

    1. I love the structure and discipline of gymnastics. As someone who can afford to have my kid in a super expensive sport like gymnastics I’m shocked by the super expensive cost of gymnastics. My daughter is only 6 and made the competitive team when she was 5. The cost of practice, meets, travel, etc are mind blowing. And both the parents and the kids can be very clique-y, which wasn’t something I expected. This is definitely not something everyone can afford. At least for some, not without great sacrifice.

      1. Is gymnastics good for developing backs? They bend over backwards so far!

  6. Growing up, my world revolved around play. But because I lived in a remote location, I was never in organized sports. That didn’t stop my brother, sister, and I from probably spending 80% of our time outside playing, adventuring, etc. When I got into high school, I was scouted to join the cross country team because one of the coaches saw me running chasing one of the other kids one day. I had never competed before but ended up winning just about every competition that year. However, the more successful I was, the more the high expectations started to get to me. I felt like I had to win every race. The coaches were also very intense and I didn’t like the atmosphere and seriousness of the competition. Running went from a very innocent and pure love to what felt like the biggest chore and demand of my life. And while I made it to state finals, I ended up quitting. Because I had to stop listening to my intuition about how far/fast to run and had to listen solely to a coach, I pushed my body way further than I knew I should have and ended up with injuries that a had to push through. It eventually came full circle for me and I’m back in love with play and movement for the sake of being a human that loves to move outside and not because I need to look good on my coaches behalf and win every race. Maybe if we put more play and maybe if we get the adults playing more too, children can rediscover their innate instinctual love of moving and playing. Also- get those kids outside! Gotta get them reconnected to nature!

    1. Awesome story! Having an active childhood like that is one of the biggest blessings, Im glad you were able to fall in love with movement again.
      I definitely agree that parents need to move more as well. Having that as an example is so powerful. Im trying to raise my kids as much in contact with nature and movement as possible (though truth be told they dont need any encouragement :))

  7. to answer your question: I am a pediatric behaviorist, and in the field of behavior analysis, there is a belief that there is no such thing as “intrinsic” or “extrinsic” motivation. Only reinforcement, and those that influence reinforcement, including ourselves. If the majority of external stimuli regarding exercise (internal states, social pressures, cultural norms) do NOT support the reinforcement of exercise, it will not increase. If they do support it (good dietary health, sleep, etc affects internal states, time allotted and social expectations and positive views and modeling from important friends and family), you will see an increase in behavior. This goes for all behavior: you have to have both Internal reinforcement and external reinforcement to override.

  8. I lost enjoyment of exercise when I was 11 and my body developed early. I’m talking a full B cup on my still-scrawny body. I started getting harassed, mocked and targeted by the boys when I would play at recess. Easier to just sit and read a book.

    That was 30+ years ago. I’m guessing things haven’t changed much for little girls.

  9. I thought about your question, how to keep kids from losing their intrinsic desire for play. I’m almost 60, but I still have it. What’s different today that affects this? I believe a large part is that the adults aren’t playing to set the tone for the kids. My very busy father, who started his own real estate business during my childhood, regularly played ball games with us. My mother incorporated outdoor activities in everything we did, some play, maybe jump rope or hopscotch, and some quasi-work, hanging out clothes (yes, I think that’s fun and still do it today) and gardening. We also played card or board games very often, even though we were all busy in school and on sports teams. We lived an active lifestyle. And I, and many of my friends continue today, biking, walking, swimming and playing strategic games. I think we need to rebuild a culture of activity for our young people today! I can’t think of anything better to be addicted to!

    1. Right on Cynthia– don’t stop moving –and if you can find an activity you really enjoy, then stopping is not an option.

  10. I like this summary,
    “That maybe you should go low-carb if you’re going to eat a lot of meat and saturated fat. And that maybe you should go low-fat if you’re going to eat a lot of carbs. ”

  11. MDA:
    My total cholesterol is pretty high and my LDL over 100 (last test did not specify actual number) but I keep my crabs low or very low for a couple of reasons: Carbs make me bloated, give me acid reflux, and even though I run/walk/life and stand all day I never feel quite right if I indulge in crappy carbs like any wheat-based or sugary foods. I had a scan done recently and the doc said I have a moderate amount of calcification in my arteries! Well, I’m 69 years old and you’d expect some of that as you age– but I move and recreate (wife and I hike a lot) like a 20-year old. I attribute this to following most of the MDA lifestyle. I’m also a preacher that loves to sermonize and could do so for hours–but then I’m afraid many of the congregation would either fall asleep or skip church altogether!

  12. Good Morning Mark.

    The study didn’t mention the participants physical activity level. We they strictly sedentary people or participants with a minimal physical fitness regime.

  13. I believe the science is strong that LDL should be lowered as much as possible for heart health. This science argues against a heavy meat and saturated fat diet. To argue otherwise seems to be ignoring established data.

    1. Which data are you referring to?
      The studies that show at best a weak correlation between cholesterol levels and heart disease, often not even that? I would not consider such studies “established data” or scientific grounds for or against a certain food.

  14. I think it falls into my suspicion that Veganism is a Religion and not healthy lifestyle. I would bet $ they are behind the “study” as well as PETA. Vegans today hide behind erroneous studies like this to pretend it’s about health when in fact it is the “superior enlightenment “ they crave by not eating tasty tasty animals and such….I know this: I have had high cholesterol and triglycerides (hereditarily) my whole life. Paleo/Keto has improved all numb

  15. I find that I am at my best from both performance and health perspectives (best blood numbers, maintenance of ideal weight, etc.), when I eat low carb Mediterranean-style diet focusing on leafy and stalky vegetables,, nuts, oils, low-sugar vinegars, berries, lemons,, fish and eggs, while drinking lots of water and smaller amounts of green tea and even smaller amounts of wine enhanced by lots of exercise and good rest.

  16. Thank you for breaking down the meat/fat study in your Sunday with Sisson newsletter! I always appreciate how you do that – in ways that are easy to share with patients and clients. Thank you!

    And love the stressed dog post:). I have two siamese cats, and they are SUPER sensitive to my moods and get noticeably upset if I’m upset….and extra calm when I’m in a happy place.

  17. It does not really matter what “I” think other than….I think we need more studies that control the variables!

  18. In response to Sunday with Sisson June 9 2019

    LOL…way back in the 80’s, there was diet style that was claimed to have come from France, where the women could eat anything, including butter, but butter was only allowed with meat and vegetables (the none starchy kinds) and never with bread or starchy vegetables…
    and now some forty years later…there are testing this theory.

  19. Sounds like the anti meat in any form groups are trying to skew studies, no matter what the conclusions, to fit their preconceived notions

  20. I love your blog. Thank you. I am a 71 year old nurse. I have seen dozens of diets, WOE and scientific contradictions come and go over my lifetime. I made the decision many years ago to follow a moderation in all things lifestyle. I have no medical issues, at 5’3” I weigh 114 lb. I eat lower carb (150), lower saturated fats, moderate protein, fewer processed foods, no fast foods, cook at home, hike routinely and swim everyday. So far so good. If I want something to eat that is less than healthy I just eat it— once in a while. I ENJOY the foods I eat. I don’t understand why people continue to make a HEALTHIER lifestyle so hard or so objectionable..

  21. Over 100 years ago, published in 1907 (if I recall!) Dr. William Hay cured most conditions of the day by diet (and there were minimal processed foods, of course). That diet is still in use as the “Hay” diet, modified of course.

    Simply stated, at any one meal, you could eat carbs and protein together OR you could eat fats and protein together, but you CANNOT eat carbs and fats together. Every diet since still doesn’t get it or is an offshoot of the “Hay” diet.

    His conclusion not to eat fats and carbs together was based on the bodies ability to digest anything, but not at the same time…something like high acid needed to break down fats and the low acid needed for carbs, so the body compromises when required to both at the same time doing both inefficiently.

    Today the science suggests other reasons, like the body uses any available carbs and stores fat, when eaten together.

    So if you are Keto, and want an apple or berries, just eat it by itself, away from your meals.

    The worst dietary advice to me is to eat a balanced diet of 1/3 of each at the same meal…a recipe for disaster.

    1. This makes so much sense to me. And “variety at every meal” is promoted so heavily. Most what I’ve read online says to eat fruit with meals or with nuts/nut butter to slow down the blood glucose spike for “more steady energy”, which may be true, but I do seem to always have difficulty with eating fruit with any other foods.
      Thanks for sharing. 🙂

    2. Oh – I had been led to believe one should not eat protein and carbs together. Some carbs, e.g. sweet potato, require the consumption of fat in order for the betacarotene to be converted to Vitamin A.

  22. Dr. Udo Erasmus who has formulated Omega3-6-9 oil in the right ratio has said that the more omega 3 fats we consume the more saturated fat our bodies can tolerate. Many of us consume too many Omega 6 fats and low carbs in combination with the oils are essential to our good health. I personally add cod liver oil to the 3-6-9- oil and eat very lo carb because I am a type 2 diabetic.

  23. With regard to your email today about a study comparing red meat, white meat, and plant protein and saturated fat levels, you didn’t comment on the plant proteins.

    What about the plant based protein? Please give us the full picture…

  24. Re. the The American Journal of Clinical Nutrition’s study referenced in your Daily Apple email, my experience with a keto diet (at about 5 months in) was to see a substantial increase in total undifferentiated LDL (114 mg/dl). But, as noted in the article, the apoB number (a confirmatory proxy for LDL risk) was very good (73 mg/dl) with the small particle size LDL particles “good” at 185 nmol/L and the medium size LDL “very good” at 210 nmol/L. HDL was optimal at 6785 so reverse transport is probably just fine too.

    While this is just one case (me) it’s consistent with the journal article. When I transitioned to the keto diet, I found myself eating a lot more red meat than I had previously; I’m now experimenting with going back to more oily fish (wile salmon and sardines mainly) to see if that lowers the total LDL.

    Thanks for your email – there’s usually something of great interest. I like your Keto Reset book too.

  25. okay cholesterol is a funny topic. I personally have high app b and high small particle LDL ( 4 times the highest which triggered investigation… and Normal! arteries as I could never have carbs re migraines, so no insulin etc) So, it appears that instead eating animal fat being a problem, it is probably the eating of the simple carbs with the meats or eggs, that actually cause the damage to arteries. So,not the fat.
    Maybe check out the Noakes foundation they have a new program on way of eating and diabetes that addresses this. You will need to take their program ( gotta buy it) but o worth it.
    You will learn why we must cook our veggies, well, at least make the effort after learning about humans being carnivores ! best, carol

  26. Is the jury still out on the detriments of saturated fats?

  27. You don’t give the results for plant protein intake with high or low fat. Were these different re LDL to the meat results?

  28. Mark, can you please switch back to the old comments system? I used to be able to get emails when someone responded to a comment I posted, now if I ask a question in the comments and someone replies, I won’t see it unless I happen to go back to that article again. I’d really appreciate if this could be fixed.

  29. Hi Mark, could you send me a link to the study you discussed on cholesterol with white and red meats please.
    Regards Dave

  30. Hi Mark, could you send me a link to the study you discussed on cholesterol with white and red meats please.
    Also your comment section keeps saying duplicate comment, but this is an original post.
    Regards Dave

  31. Response weekly link love 32.

    Ahh, the cholesterol conundrum continues.

  32. The children aren’t losing their motivation for exercise, but for PE. That’s a huge difference.
    I always hated PE, did everything I could to get around it – and then spent the entire afternoon outside biking, horseriding etc. How about we don’t force kids into involuntary exercise that is (as many things in school are) paired with shaming, judgment, and grades while at the same time punishing them for the impulse to exercise the entire rest of the time they’re in school?

  33. WLL#33 should be available. The cholesterol/meat SFA study summary in Sunday with Sisson 9 June is awesome and I’d love to share the article with friends. Without copy/paste to my own website and share from there what can I do?

  34. Before judging this research further, I would want to know the diets of the animals…whether for meat or dairy. I think
    grass fed meat/dairy would have a vastly different fat profile and affect on our bodies than if it is grain/GMO fed.
    We are what we eat, but I think we are also what our meat eats….

  35. Mark I sincerely suggest you interview David Feldman. He has a lot to say on Cholesterol and Fat.

  36. This post showed very good understanding and it was well-thought out work. I’m obsessed with reading any article for help I can find. Thank you for sharing.
