Feasting and Fasting

As an ode to the gorging that tends to go on this time of year, I decided it is important to understand how the body responds in times of excess and scarcity. Every now and again we all tend to eat more than we need or wish we would have, and in response to this, we compensate by not eating for abnormally long periods of time, or over exercising. All foods eaten in excess can be stored as fat, and depending on our hormones and energy requirements, will be stored as fat.

Not surprising fat is the most readily of the macronutrients to be stored as fat, and takes 1/5 of the energy of carbs to be converted and stored as fat. Most of the dietary fat consumed is stored in the attractive adipose tissue in the body. Interestingly enough however, short and medium chain triglycerides such as coconut oil and butter are processed in the liver and used as a direct energy source rather than for storage.

When carbohydrates are consumed, they are first converted to glycogen and stored in the liver and muscles for our energy demands of normal bodily function. When carbs are eaten in excess insulin will direct the glucose to be stored in fat cells rather than in the muscles and liver.

Despite popular belief and practice, eating copious amounts of protein will not transform you into a muscle factory. Protein is first used to replenish our daily losses of protein, and can be used for energy when carb consumption is low (this is the basis of low carb diets). Beyond those needs however, protein, just like fat or protein eaten in excess can be stored as fat.

When we eat a meal the body uses all the nutrients consumed to replenish losses and then stores them for later use, as the body is in constant need for fuel, even during sleep. After about 4-5 hours the body has gone through most of the energy from the previous meal, and begins to go into a fasting state and begins to draw on the stores of energy. It will first use all excess carbs from the liver and the muscles, (this will last us up to 8 hours) then the body goes to excess fat and proteins to create energy. Fat breakdown almost doubles during fasting, and the body will begin to break down proteins in the muscles and the liver to get amino acids to make glucose for the nervous system and blood cells.

These dietary and systematic changes can inhibit our energy levels, appetite, metabolic rate, and mood amongst other things, which is why it is important to eat a consistent diet throughout the day and not starve in order to lose weight or to be able to feast at a Christmas party. Our bodies like consistency and you will function at a much higher level if you do not subject your body to constant changes of caloric supplies.

Men v. Women

I am going a little out of my depth this week, but I felt like a challenge. As part of my moving to Colorado, I have become more aware and respectful of the woman athlete since much of my training is done with one. We often talk about nutrition and what we eat in a given day or for a race, and it got me thinking about what I need to eat versus what she needs to eat, and how much and in what areas our nutritional needs vary.

It is no surprise that men generally weigh more than women, have more muscle mass, thus a higher basal metabolic rate, and therefore require more calories than women in a given day, but what are the differences beyond the calories? Do men need more of certain nutrients and less of others or just more of everything? Well, prior to puberty the nutritional demands of boys and girls are not all that different, but once women become child ready their specific needs begin to manifest. The main differences in nutrition highlighted here involve iron, calcium, and folate.

Since women have more ongoing cycles in their body then men, they are more prone to certain nutritional deficiencies, and with lower caloric needs in general, it can be difficult to overcome these deficiencies. Blood loss can lead to iron deficiencies which makes it harder for women to receive adequate amounts at certain times. Men need about 8mg per day while women need about 18mg (28 when pregs) per day, while men easily get this from their food, it is harder for women since they need less food in a given day. Iron is important for the formation of hemoglobin (maintains oxygen in the blood) and the production of energy. Low iron can increase fatigue, and decrease concentration and memory. Iron rich foods include spinach, chard, beans, fish, meat, and peas.

Calcium is also more important for women than men. Thanks to milk ads, we all now that calcium is important for strong bones and to prevent osteoporosis, but it is also important for blood pressure, muscle contraction, blood clotting, immune function, and the transmission of nerve impulses; wow right? It’s that important, and for women its more important than men. Some calcium rich foods include kale, spinach, brussel sprouts, nuts, seeds, and figs. If you’re a numbers guy or gal shoot for about 1000-1500mg/day.

Lastly, folate; folate is one of many of the B vitamins, B9 to be specific, and is very important for all women wanting to have kids, since it has been shown to reduce the chances of neurological birth defects, as well have an impact on the overall fetal development. Folate also plays a role in cell production and formation (hence pregnant women), DNA synthesis, bone strength, depression, and fatigue. Good sources of folate include spinach (shows up a lot huh?), broccoli, beets, and beans. Shoot for 400-600mg(women) a day.

Beyond the biological differences, nutritional demands can vary between men and women for other reasons, most notably, the obsession women generally have with their weight. I am not saying men do not share it, and for those of you that know me personally, know I am probably worse than most women, but women tend to exercise for weight loss while men tend to for muscle gain, which implies more. Insufficient caloric intake can have several negative effects that accompany weight loss. So please be sure you are eating enough if you are going to exercise. More on this next week.

Proteolytic Enzymes

I trust everyone had a nice Thanksgiving and got some good food and football in; I had a great time with my family at our ranch in TX, and besides the Dallas and Miami games, I had a great Thanksgiving. Now, on to the good stuff, to follow up on the importance of enzymes and hydrochloric acid for digestion and health, I am discussing a specific group of enzymes important for athletes; systemic or more commonly known, proteolytic enzymes.

So what are proteolytic enzymes; they are protein eating enzymes. Now your probably saying “wait a second, I thought enzymes are proteins so check it Jay!", and your right, but these specific types of enzymes eat dead proteins from our bodies, which has significant health benefits for us, and most notably, athletes; primarily, reducing inflammation. This works because inflammation after an injury causes accumulation of proteins and fluid in the extracellular space which causes swelling and pain. Next, the blood begins to clot which blocks circulation. This is where the enzymes earn their stripes, they dissolve these blood clots to allow oxygen to reach damaged tissue to promote healing of damaged tissue and eliminate inflammatory debris from the injury. Regular training sessions can also have the effect of acute inflammation which can lead to similar clotting, so do not mistake this therapy for only serious injuries; it can be effective no matter how your body is feeling. As we also know, despite the numerous health benefits that come with exercise, high volume and intensity training present the body with a significant amount of stress that can weaken our immune system and function. These enzymes have shown to help maintain normal immune function and reduce inflammation despite high training demands, which can improve recovery.

Proteolytic enzymes improve blood circulation by eating excess fibrin (a blood clotting protein) that can cause our blood to thicken, trap red blood cells, and cause the liver problems when cleansing the blood. This gives us cleaner blood that is less prone to clotting, and stronger white blood cells to improve our ability to fight off infection. These types of enzymes are also useful for immune support as they are responsible for killing parasites, bacteria, viruses, and fungus which are all protein based invaders.

Supplementation of these enzymes can aid all kinds of ailments including infections, food allergies, post surgical healing, arthritis, cancer, lupes, MS, and Crohns. In order to receive the full healing benefits from proteolytic enzymes they MUST be taken on an empty stomach so no digestive effects interfere with the passing of the enzymes through the stomach lining into the circulatory system where they can go to work. When choosing a supplement it is important to find a product that lists the enzymes contained and not a “proprietary blend” of enzymes; the most important proteolytic enzymes include pancreatin, trypsin, papain, peptizyme, and bromelain, so look for these in choosing a supplement.

Enzymes and Stomach Acid

The next two weeks we are going to get into the world of enzymes and learn their function and importance to our health. First I will explain and enzymes and then next week discuss enzymes’ role in athletics. Enzymes are functional proteins that act as catalysts to perform important functions in digestion, metabolism, and detoxification. There are thousands of enzymes, but they all fall into one of three groups; 1) digestive, to help break down food. The major digestive enzymes are protease, lipase, and amylase, used to digest protein, fats, and carbs. 2) Metabolic, necessary for body function, and, 3) plant based enzymes from raw food, to prepare and aid food in digestion. Without enzymes no reactions can take place in our body; vitamins, minerals, and hormones cannot function without enzymes.

There are thousands of enzymes in the body and each one of them can only perform one chemical reaction, but, enzymes can be used over and over again to perform that function. As previously stated, those major functions include digestion and the chemical reactions in our body such as detoxification, cell regeneration, immune support, metabolism for energy production, and synthesis of hormones and vitamins.

Digestive enzymes can be lost through sweat, waste, and ageing, so it is important to supplement enzymes as well as eat lots of raw foods if you can. Some of the major benefits to enzyme supplementation include:
• Improved digestion
• Strengthen our immune system
• Give our bodies more antioxidants
• Reduce injury and inflammation
• Aids in reproduction problems

Before running off to get digestive enzymes it is important to understand the role of hydrochloric acid in the stomach, and ensure you are producing adequate amounts in your stomach. If there is not enough stomach acid then proteins cannot be digested, digestive enzymes cannot be stimulated, and bile release will be inhibited causing problems for the gall bladder which stores bile. That’s right, if you do not have adequate stomach acid, you cannot use enzymes, and will not properly digest food. Symptoms of low stomach acid (hypochlorhydria) include constipation, halitosis, undigested food in stools, and acid reflux, so, ensure proper stomach acid prior to beginning enzyme supplementation.

Have a great Thanksgiving, and have some enzymes for your appetizer.

WATER

This week may be the most important post I will ever do because the subject matter is so vital to all body function, especially athletic function, and the number one answer to many problems that we suffer on a daily basis.

All actions in the body require a medium to occur and this medium is one of the most readily available as well as ignored substances in the planet; water. Our bodies our comprised of about 70% water in the form of blood, lymph (transports cells, bacteria, and fats), and other cellular fluid. Some of the major functions of water in the body include transport, lubrication, molecular structural support, regulating of body temperature, and maintaining blood volume. When we do not drink enough water our body is forced to prioritize what systems will get water. What this means is that the body will cut back on functions to preserve water for the brain, which is about 80% water, and cause us to experience fatigue, energy loss, constipation, lack of focus, cramps, weight gain, digestive problems, skin problems, joint pain, blood pressure imbalance, and premature ageing.

This leads to a question I am sure is entering your mind at this point; how much water should I drink and what kind of water should I drink? It is recommended to drink about 2.5 to 4 liters of water, which for my US readers is slightly over 10 to 16 Cups of water a day. For me, an easy way to get me going in the right direction is to have 32oz of water with ½ a lemon juice right when I wake up. Not only does this get me a large portion of water early on in the day, but the lemon helps my liver jumpstart its detoxification processes. It is important that the water is room temperature and that you use real lemons, not juice from the plastic lemons for sale at the grocery store.

When you train your gonna need a lot more water, and it is important to hydrate during training if you can. A 2% loss in body weight during exercise has the effect of a 20% decrease in performance, and for endurance athletes this can have a tremendous impact on results. It is important to drink before training, and drink 8 oz or so every 20 minutes if you can during a session. If your going for more than an hour be sure to add some electrolytes to the water.

With all the functions performed by water in the body, it is clear that high quality water is important to achieving optimal health. The best source of water is strangely highly debated and can be too expensive, or impractical to fully experience. Looking past the high priced filtered and from the source spring water, we are left with carbon filters (Pur/Brita), distilled, bottled, reverse osmosis, and tap water.

First the easy ones, the only thing worse than tap water is paying for filtered tap water in a convenient BPA laced bottle (Dasani, Aquafina, etc). Tap water contains many harmful chemicals such as fluoride, nitrates, lead, and the scariest to me, pharmaceuticals. Your carbon filters are a great choice and will get rid of 95% of these chemicals but not all of them, and not the pharmaceuticals. Your best value option is to get real spring water from a trusted source in your area. Many companies deliver and some grocery stores will sell the spring water in 5 gallon jugs at a very reasonable price. Distilled water is also a good choice, as this is the purest water you will find; it is completely void of all and any impurities or contaminants, but is also void of minerals.

Also, it is important to touch briefly on what does not count as water for our daily needs; coke, sports drinks, energy drinks, tea, coffee, and lemonade, while being made largely of water, do not count as water. Many of these act as diuretics, which actually have a dehydrating effect on our bodies, and the others are loaded with sugar which can also negatively affect hydration as well as many other systems in the body.

I know that it is not always practical to follow these guidelines, and please do not forgo water when you cannot find a good source. If all you can drink is bottled water just be sure to look at the bottle and see what kind of water you are drinking. Also if you must, drink tap water do, but this is a rare justification as it is pretty easy when traveling try and go to a grocery store and buy the gallon jugs of distilled water right when you get to your destination so you can have high quality water and do not have to make compromised decisions.

Drinking high quality water is crucial to our health and with proper planning and budgeting can be an easy way for everyone to improve health and vitality. Try implementing some of this education and see if it doesn’t make a difference.

Energy

First off, to the handful of family and friends that read these, I want to apologize for the absence; its not like I have been too busy, I just have not been into writing for the last couple of weeks. So, for those of you reading this week, thanks for stickin with me, and I will try to do better.
I was recently asked about low energy and sources other than caffeine to help get us going in the morning or through that tough period in the afternoon that seems to always come around 2 or 3 in the afternoon. Personally, I know that when I have to be sitting down all day it seems that I often get tired at the same time, and there are several reasons for this. So for the majority of people who do not have a job that allows them to constantly be moving, I will address a few possibilities for your fatigue with remedies.

First off, the obvious, you’ve been sitting on your butt for too long! Get up, and go for a walk around the office, do a couple of push ups at your desk, (I’ve seen it) or venture outside and take a walk, and get some vitamin D,…two dragons.
Second, your tired. I know this too is in the obvious category, but I am always amazed to hear that people sleep 4-5 hours a night and expect to be able to get through the day. That is not going to cut it, and if you take a little more interest in getting 6-8 hours it may have tremendous effects on your energy throughout the day.

Third, your diet is off. Besides poor diet choices which can often times translate to lethargy, when we go through long stretches without eating or do not eat enough, our bodies can produce excess insulin, which drains our energy because we do not have enough glucose in our bloodstream (low blood sugar). It may help you to eat a snack a couple of hours before or after lunch to get the body going a little bit, and your blood sugar stable.

Fourth, your dehydrated. Our bodies, much like the world are 2/3 water, and when there is not enough of this precious liquid it can cause, among other concerns, our blood to thicken which makes our heart work harder to move blood, and deprive us of the movement of many nutrients needed for energy through the body.

In conclusion, there are several reasons why you may get tired at work in the afternoon, many of which are diet related, and there are several non-caffeine answers to the problem. If none of these alternatives work for you and you feel like you “have to have coffee” have A cup, but do try and keep it minimal or, try an alternative good quality organic tea, a couple of squares of dark chocolate, yerba mate, or if you can get it, wheat grass.

Soreness, aches, and pains

Aches, pains, and soreness are part and parcel to training and exercise. Much of this is caused by bad technique, extending ourselves beyond what we can handle, as well as insufficient rest and recovery. Diet can be a tremendous factor in soreness as well as how long you deal with many of pains of training. Certain foods such as processed foods, high protein diets, high amounts of omega 6’s (soybean, cottonseed and corn oils), and sugary foods promote inflammation which in turn promotes pain in the body, while other foods are anti-inflammatory and can ease much of the discomfort often experienced during and after exercise. Some of the best foods to combat inflammation in the body include grapes, berries, pineapple, cherries, kiwi, celery, garlic, salmon, curry, turmeric (contains the popular healer curcumin), and ginger. Also high amounts of foods rich in vitamin C and E such as nuts, seeds, peppers, and broccoli are beneficial.

A few of these foods have been studied and shown to reduce muscle pain, swelling, and damage. Cherry juice has been studied by the British Journal of Sports Medicine to reduce muscle pain and damage, and ginger has been shown to reduce muscle soreness when taken after a workout by the University of GA. A note on the ginger, please do not think this means to down handfuls of the candied ginger, because that is not ok, this means fresh ginger added to smoothies, teas, or dressings.

Researching this topic I came across a few home remedies which I thought were interesting; one was to make a mixture of 1C ACV (apple cider vinegar) 1C honey and 8 cloves in the blender and then mix 2T of that mixture into 8oz of water or fresh juice. This was shown by the University of Edinburgh to reduce pain in those suffering from arthritis by 90%. Have not tried this one, but since I like all things honey, I will be shortly. Another interesting remedy I came across was to take a shower with intervals of 30 seconds of cold followed by 2 min of warm to open and close the capillaries in an effort to flush lactic acid from the body. Not sure about this one, especially since its starting to cool down out here in CO, but it does seem easy enough to give a shot, just may have to wait till April for me.

Last thing on soreness and injury I want to mention, is proper refueling after exercise. It is important to refuel the glycogen stores (the body’s fuel) immediately after exercise. This is best done with fruit or other simple carbs within a 30-60 minute window after training. If this is not done it can take up to 48 hours to replenish glycogen which could lead to reduced performance and injury in subsequent days. One of my go to post work out drinks is a smoothie with banana and celery for the great sources of potassium and sodium in those foods, since it is important to get electrolytes back in the system for recovery.

Have a great week

Tip of the week- Fall is great time of year everywhere...
