I have actually read some of the links on the crossfit guide. I was looking into it before I tore my ACL.

My understanding is that humans were hunters and gathers for thousands of years. They ate many plants and included a large amounts of roots, tubers and even gains in their diet. Carbs are the bodies main fuel source and I would suggest it is for a reason. They are the most plentiful biomolecule on the planet. Fruits and vegetables are mostly carbohydrates, so why keep to fruits and vegetables above gains? It’s usually due to the density between the two. Fruit has more water to go with the calories so you feel more full and hence eat less.
Grind with a wheel of with your teeth? Most people live longer than 25 these days, you need something softer to keep your jaw from wearing down. The degree of processing could be argued well. The point is you don’t want to significantly change the components and nutrients in foods. Some processing, such as baking, increases the amount of usable sugars and nutrients available in grains.
In the last few thousand years many cultures have evolved to the point where they maintain their ability to process milk through life. We can evolve.
My conclusion? Those people who are trying to lose weight, gain muscle and are willing to change their diet to match are the ones who are serious and dedicated. They watch their calories and train hard. It’s true a certain amount of protein is needed to build muscle mass, but I have read it’s much less than the 1g per kg most suggest. Yes, protein is converted into carbs as needed, but the reverse is not true. My point there is that overeating protein isn’t bad for you, but not eating enough can make it hard to build muscle. However; I would think they could eat a balanced low calorie, sufficient protein diet and get similar results.

Fruits and veggies are kept above grains (in Paleo and Primal) more because of the density of all the other nutrients. You get a ton more vitamins and minerals and fiber from 100 calories of fruits and veggies than you do from 100 calories of corn and wheat.
ReplyDeleteTo a point, but vitamins and minerals are not always useful. If I remember my biology correctly many of the critical vitamins and minerals are water soluble and so are just flushed from the body if your eat too much; they don’t hurt you they just don’t help either.
ReplyDeleteRight – but you’ll have to eat a whole lot more to get your 100% of your recommended intake from grains than you would if you ate a variety of vegetables and some fruit.
ReplyDeleteYou need to eat a certain amount of calories every day anyway. So I pull my nutrients from 400 calories worth of fruit or 1500 calories worth of grains? I’m still going to have to eat more than just the fruit every day to stay alive.
ReplyDeleteRight, but I’d rather fill up my remaining calories with protein, and an increased protein intake requires a slightly increased fat intake (rabbit starvation…). So.. vitamin dense veggies! :)
ReplyDeletePersonal choice in the end.
I was saying earlier, most people vastly overestimate their protein needs. If that’s where you want to get your calories from that’s great, but now everyone does. That’s why I argue balance and not cutting anything out. The easier a diet is the more likely you will stick with it long term.
ReplyDeleteLewis and Clark had the same issue eating Elk once they reached the west coast, they would eat 6 lbs a day and were always hungry.
If the rest of the world ate meat with the same consumption as Americans, we would need four earths to maintain that level of consumption.
ReplyDeleteOr one fourth the population…
ReplyDeleteIf the rest of the world ate food with the same consumption as Americans, we’d need twelve earths to hold all the fatties.

ReplyDeleteYou must have missed the email I sent earlier saying people have a lot of success with a wide variety of diets, not just the low-carb stuff. ;)
ReplyDeleteProbably, I’m working on this **** game. My attention is really on that. But yeah, take in less calories (beer counts), eat sufficient protein and nutrients, lift more and get 8-9 hours a sleep a night. If you do not get enough sleep you will eat more (lack of sleep causes hunger) and not build muscle.
ReplyDeleteSee? Dave and I can agree on all kinds of stuff. :)
ReplyDeleteWow, I just read the blog link. This guy is thinking backwards. I kept expecting him to decry vaccinations and modern medicine.
ReplyDeletePlants dude! Natural remedies will cure your cancer and let you live to be 9000!
People evolve, we cook meat and drink milk from other species. We adapted to do this. Can preservatives and man-made chemicals be bad for you? Yes. Are they all? No.
"Nature=good, man=bad"? Such ignorance.
