Is your weak butt giving you back pain?

Sitting all day leads to glute inhibition and quadricep dominance. When we sit all day, the glutes are seldom called upon to perform their primary purpose, which is hip extension (pulling the leg behind you). So we end up with tight, overactive hip flexors, and weak, overstretched glutes. When the glutes no longer work appropriately, the hamstrings and lower back muscles must compensate and work double-duty.

Weak glutes/tight hip flexors also lead to shortened hip extension movement, which leads to a compensatory over-arching of the lower back (increased lordosis). This leads to compression on the facet joints and intervertebral disks.

When the pelvis stays tilted forward (the increased lordosis, above), the abdominal muscles become overstretched and weakened, and the lower back muscles shorten and tighten. So you are left with overactive and abused hip flexors and lower back muscles, and glutes and abdominals that are not working.   

If you wanted to create a recipe for low back pain and dysfunction, the list of ingredients would be:

  • tight/overactive hip flexors and quadriceps
  • weak/inhibited glutes and hamstrings
  • weak abs and tight lower back
  • anterior tilt of the pelvis (hyperlordosis of the lumbar spine)

My Comments on the Paleo Diet

Comments on the Paleo Diet

(See my comments in blue.)


The Paleo diet should be high in fat, moderate in animal protein and low to
moderate in carbohydrates. Calorie counting is not encouraged, neither is portion
control.


I would be careful with an eating plan that states that portion control is not
encouraged.


Eat unlimited amounts of saturated fats like coconut oil and butter or clarified
butter. Beef tallow, lard and duck fat are also good, but only if they come from
healthy and well-treated animals. Beef or lamb tallow is a better choice than lamb
or duck fat. Olive, avocado and macadamia oil are also good fats to use in salads
and to drizzle over food, but not for cooking.


Eat generous amounts of animal protein. This includes red meat, poultry, pork,
eggs, organs (liver, kidney, heart…), wild caught fish and shellfish. Don’t be
scared to eat the fatty cuts and all meals with proteins should contain fat as well.
Learn to cook with bones in the form of stocks and broths.


It's true that saturated fat is only harmful to the arteries in the absence of
adequate HDL, adequate omega-3 intake, and lack of inflammatory
response in the system. Not too many people have all three of those
under control, so be careful about eating too much saturated fat if you are
a "normal" person. Remember the Atkins Diet argument? Same thing
here.


Eat good amounts of fresh or frozen vegetables either cooked or raw and served
with fat. Starchy vegetables like sweet potatoes and yams are also great as a
source of non-toxic carbohydrates.


Eat low to moderate amounts of fruits and nuts. Try to eat mostly fruits low in
sugar and high in antioxidants like berries as well as nuts high in omega-3, low in
omega-6 and low in total polyunsaturated fat like macadamia nuts.


Amen to all this.


Consider cutting off fruits and nuts altogether if you have an autoimmune
disease, digestive problem, or are trying to lose weight faster.

Nuts are common allergens for many people, and some people do not do
well with fructose, so I don't have a problem with the above if you fit the
described demographic.


Preferably choose pasture-raised and grass-fed meat coming from local,
environmentally-conscious farms. If not possible, choose lean cuts of meat and
supplement your fat with coconut oil, butter or clarified butter. Also preferably
choose organic, local and/or seasonal fruits and vegetables.


Good stuff, except you probably don't need to add more saturated fat to
your animal protein. Instead, spice it up with spices like rosemary,
oregano, cinnamon, turmeric, black pepper, cloves, garlic powder and
paprika -- these antioxidants reduce the triglyceride response from fatty
foods.


Cut out all cereal grains and legumes from your diet. This includes, but is not
limited to, wheat, rye, barley, oats, corn, brown rice, soy, peanuts, kidney beans,
pinto beans, navy beans and black eyed peas.


This is the kind of thing that makes "diets" unsustainable. Eating fewer
grains and more vegetables is a fine principle, but trying to cut out all
grains is very, very difficult, not to mention unnecessary. Additionally, one
will be hard-pressed to present a reasonable argument for legumes being
a problem.


Cut out all vegetable, hydrogenated and partly-hydrogenated oils including, but
not limited to, margarines, soybean oil, corn oil, crisco, peanut oil, canola oil,
safflower oil and sunflower oil. Olive oil and avocado oil are fine, but don’t cook
with them, use them in salad dressings and to drizzle over prepared food.


Correct.


Eliminate sugar, soft drinks, all packaged products and juices (including fruit
juices). As a rule of thumb, if it’s in a box, don’t eat it. At the grocery store, visit
only the meat, fish and produce sections.


Sound advice.


Eliminate dairy products other than butter and maybe heavy cream. You don’t
need dairy, but if you can’t live without, consider raw, full-fat and/or fermented
dairy.


Ah, the dairy argument. Given the available science, one can make a
reasonable argument both for and against, so I don't really have a strong
stand one way or the other. If you tolerate dairy well, go ahead, but use
hormone-free product from organic farms. If dairy gives you inflammatory
response, gastric upset, or mucus over-production, either skip it, or try an
alternative like sheep's milk or goat milk, or try dairy from European cows
– they are typically from a different genetic strain, and some folks with
lactose intolerance to milk from western genes can consume European
milk with no problems.

Glycemic Index

by Nashville personal trainer Dan DeFigio

Glycemic value is a measure of how fast the carbohydrates of a particular food enter the bloodstream. The value assigned to a particular food is an average blood sugar response of various subjects tested. Foods with a higher GI rating enter the bloodstream more quickly. As a general rule for fat control, avoid eating too many high glycemic carbs. Extra insulin is turned into bodyfat.

ATTENTION DIABETICS:
Glucose response to a particular food is highly individual. Combinations of different foods can produce unexpected results. Also, the way food is prepared can have an effect on the GI. Therefore, you should always monitor your own blood glucose levels after eating particular foods to determine if they have a high or low GI for you.

Gluten-Free Diet

Gluten Allergy - (Celiac Sprue disease)

by Nashville personal trainer Dan DeFigio

Gluten is a mixture of two proteins, gliadin and glutenin. When mixed with water, it becomes sticky and so forms the familiar texture of dough made from wheat and rye flour. When gluten comes into contact with the lining of the small intestine, a reaction occurs, where the immune system mistakenly attacks the lining of the bowel as if it was a 'foreign' organism.

The small intestine has 'villi', which are tiny finger-like projections, visible under the microscope. They provide a large surface area, over which we absorb nutrients, such as vitamins, folic acid, iron and calcium. In coeliac disease these villi are attacked by the immune system and are eventually destroyed. This results in food going down the gut without nutrients being absorbed (malabsorption), leading to vitamin and mineral deficiencies, anemia, and osteoporosis.

Gluten is found in wheat, barley, and rye. That means a gluten-free diet cannot include bread, biscuits, cakes and pastries, pasta, common breakfast cereals, and many manufactured soups and sauces. Gluten is also hidden in some foods such as chips and similar snacks, as well as chips in restaurants. Stay away from “modified food starch” too.

Cooking oil (or mixed vegetable oil) can contain wheat-germ oil, so use sunflower or olive oil instead. Malt vinegar, soy sauce, mustard and mayonnaise contain gluten. Beer and whisky are made from grain containing gluten, but other alcoholic drinks, such as wine or cider are gluten-free. Most specialists now consider all distilled forms of alcohol safe to drink, provided no colorings or other additives have been added, as they might include gluten ingredients. Wine, sherry, port, cider, rum, tequila, bourbon and vermouth are all probably safe. Liqueurs and pre-mixed drinks should be examined carefully for gluten-derived ingredients.

Special care must be taken when checking ingredients lists as gluten may come in forms such as vegetable proteins and starch, modified food starch (when derived from wheat instead of maize), maltodextrin, malt flavoring, and glucose syrup. Many common ingredients contain wheat or barley derivatives.

Some medicines contain gluten, so you must check with your pharmacist.

The suitability of oats in the gluten-free diet is still somewhat controversial. Some research suggests that oats in themselves are gluten free, but that they are virtually always contaminated by other grains during distribution or processing (most oats are milled and stored in the same mills as wheat and are probably contaminated with gluten). However, recent research indicated that a protein naturally found in oats (avenin) possessed peptide sequences closely resembling wheat gluten and caused mucosal inflammation in significant numbers of coeliac disease sufferers. Some examination results show that oats are very dangerous to certain celiacs, while not very harmful to others. Given such conflicting results, excluding oats is the only risk-free choice for coeliac disease sufferers.

Hidden Gluten
Here's a list of places you might not expect to find gluten:

  • Sausages contain breadcrumbs (the bread is one of the ways in which the texture of the sausage is obtained, without including an unacceptably high proportion of fat), except the most high class variety of butcher's sausage, and even in this case it's quite likely.
  • Burgers, grillsteaks and similar products generally also include bread or other wheat products in the mixture.
  • Crab sticks and prawnies seem to be made entirely of fish, but if you check the label and you will find wheat flour or modified starch listed in the ingredients.
  • Some drinks contain gluten as a thickener, to provide 'body'.
  • Wheat flour may be a hidden ingredient in ice cream, ketchup, mayonnaise and instant coffee.
  • You often find gluten in low fat versions of products, to make them seem less watery (for example, yoghurt, soft cheese or mayonnaise).
  • Pre-packed grated cheese is coated in flour or modified starch to stop it from sticking together in the packet - this includes the cheese sold with jacket potatoes in takeaways, unless they grate their own (but most don't).
  • Obviously, anything coated in batter or breadcrumbs contains gluten in the coating. This makes almost every fish product out of bounds for the gluten intolerant, as the ones that aren't coated are usually packaged in a sauce thickened with flour.
  • Monosodium glutamate, known to Chinese cooks as 'taste powder' or 've-tsin' is manufactured with gluten. This ingredient is very frequently included in factory-prepared goods, but may not be listed on the label - or merely described as a 'flavor enhancer' or 'natural flavoring'.
  • Soy sauce is almost always made by fermenting soy beans and wheat together, so contains gluten.
  • Although wheat germ does not itself contain gluten, because of the process of separation employed in manufacture, it is likely that a small amount of gluten will be present in wheat germ sold in the stores.
  • Malt and malt extract are derived from wheat, and can be a hidden source of gluten. This is sometimes listed as maltase or malto-dextrin.
  • Any alcoholic drink made from grain -- beer or whisky, for example, contains gluten.
  • Even medicines may contain gluten, used as a thickener or a binder.

Gluten-free food

Of course, many foods do not contain gluten, including all fruits and vegetables, rice, maize, sweet corn, nuts, potatoes, red meat, chicken, fish, eggs, and dairy products (although a lot of patients with gluten allergies also react poorly to dairy, so if a gluten-free diet does not improve your symptoms, we should look at a dairy-free diet too).

Several grains and starch sources are considered acceptable for a gluten-free diet. The most frequently used are maize (corn), potatoes, rice, and tapioca (derived from cassava). Other grains and starch sources generally considered suitable for gluten-free diets include amaranth, arrowroot, millet, montina, lupine, quinoa, sorghum (jowar), sweet potato, taro, teff, and yam. Various types of bean, soybean, and nut flours are sometimes used in gluten-free products to add protein and dietary fiber. In spite of its name, buckwheat is not related to wheat; pure buckwheat is considered acceptable for a gluten-free diet, although many commercial buckwheat products are actually mixtures of wheat and buckwheat flours, and thus not acceptable.
