Why Zinc Is So Important
Here is an article which I wrote a few years ago and which still applies to general health:
Zinc is a vital mineral which is found in every tissue in the body due to its involvement in cell division. In the world of fitness and bodybuilding, zinc has a number of roles, including maintenance of normal hormonal levels, proper endocrine function, body composition, energy levels, optimal physical performance and protein synthesis. Thus it is crucial to maintain normal levels of zinc in the body when training or prepping for a competition.
Zinc is highly concentrated in meat, dairy and some seafood. This is why vegetarians most commonly suffer from zinc deficiency. So how can you tell if you suffer from a zinc deficiency? Common symptoms include an altered sense of taste which leads to cravings for sweets and salty foods. Other symptoms of zinc deficiency include low energy, infertility, low libido, memory problems, poor immunity and diarrhea.
A relatively easy way to test yourself to see if you are deficient in zinc is to do a taste test. Take 1 to 2 teaspoons of zinc sulfate (you can get this at health food stores) and add to a cup of water. If it tastes just like water, you are very zinc deficient. If you experience a slightly metallic taste, you are moderately zinc deficient. If it is strongly metallic and unpleasant, you most likely have normal zinc levels. Please bear in mind that this test is never as accurate as a blood test, but at least it will give you an idea of what your levels are.
For those of you who want to know the specific health benefits of zinc, here is a list of benefits.
Enhances Strength and Athletic Performance:
Zinc plays a major role in anabolic hormone production which makes it a key player in optimizing athletic performance and strength. When zinc levels in the body are normal, more growth hormone and insulin-like growth factor-1 is released, which result in enhanced muscle growth and performance. Researchers have also noted that zinc enhances the conversion rate of androstenedione to testosterone, which improve strength gains during the recovery phase.
Enhances Reproductive Health and Fertility in Both Men and Women:
The cells of the male prostate require an extremely high concentration of zinc for proper function. To give you an idea of how much zinc is necessary in the prostate, male prostate tissue requires ten times more zinc than other cells in the body for normal function. There is a correlation between low zinc levels in men and increased risk of developing prostate cancer and infertility. There is also evidence to support the link between low zinc levels and low libido. Another implication with low zinc levels is its importance in maintaining optimal testosterone levels. Men with low zinc also tend to have low testosterone, which puts them at greater risk of andropausal symptoms.
In women, proper levels of zinc are essential for egg maturation and ovulation. Zinc also optimizes utilization of estrogen and progesterone and regulates their levels. During pregnancy, zinc plays a vital role in ensuring proper cell division in the growing fetus and helps to prevent premature delivery.
Essential For Taste, Smell and Appetite:
Zinc activates areas in the brain that process information from taste buds in the mouth and olfactory cells in the nasal passages. In addition, levels of zinc in the plasma influence taste preference and appetite. Many programs which treat anorexics use zinc to revive taste and appetite.
Makes Skin, Hair and Nails Healthy:
Zinc accelerates skin cell renewal which is why it is commonly used in diaper rash creams, acne treatments and creams which are used to treat dermatitis. It has strong anti-inflammatory properties and has a soothing effect on rashes, burns and blisters. Some shampoos contain zinc to help prevent dandruff. What you may not know is that zinc is important for healthy hair and that low zinc levels can cause hair loss, dull and thin hair, and loss of pigmentation.
Essential For Vision:
Zinc is found in high concentrations in the retina, but this level declines with advancing age, precipitating age-related macular degeneration which is characterized by a partial or complete loss of vision. Zinc also has a protective effect against the development of cataracts and night blindness.
Supports Cardiovascular Health:
Zinc is vital to normal cardiovascular function. When levels of zinc are low, the endothelial layer in blood vessels becomes inflamed and accumulates cholesterol deposits, both of which increase one’s risk of heart disease. Low levels of zinc can amplify the negative cardiovascular effects of diets which are high in fat and cholesterol, whereas adequate levels of zinc will inhibit the progression of heart disease.
Increases Insulin Sensitivity:
The presence of zinc is essential for normal function of most hormones, including insulin. Zinc binds to insulin and aids in storage in the pancreas as well as release of insulin in the presence of serum glucose. In addition, zinc is found in the enzymes which enable insulin to bind to cells so that glucose can be utilized for fuel, a process better known as insulin sensitivity. Why is this important? If zinc levels are low, enzyme levels drop, insulin sercretion drops and glucose remains in the bloodstream, a process which can lead to diabetes if it is chronic.
Improves Mood:
Dopamine, a chemical in the brain which boosts mood and energy, is partially regulated by zinc, so zinc once again plays an important role in the body. There is also evidence to support the theory that the presence of zinc boosts serotonin levels in the brain.
Supports Immune Function:
Zinc supports T cell function and is thus strongly tied with combating inflammation. T cells are responsible for mounting an immune response to invaders such as bacteria or viruses.
Has Potent Antioxidant Effect:
Zinc can remove toxins from the body and prevent accumulation of harmful compounds in tissues. This mechanism has a protective effect against the development of cancers, especially in the prostate, ovaries, pancreas, breast and colon. In addition, zinc prevents the buildup of heavy metals in the brain such as aluminum, which has been closely linked with Alzheimer’s disease.
If you suspect that you are deficient in zinc, you can supplement daily with 20 to 30 milligrams.

Work Out Like You Mean It!
Are you one of those people who has had an active gym membership for a while, but just can’t motivate yourself to avail yourself of the services which your gym offers? Perhaps you are new to a gym environment, and though you are interested in transforming your body and your lifestyle, you are intimidated by all the weights and machines. If that’s the case, a knowledgeable certified fitness trainer with whom you have a good rapport will familiarize you with the equipment and how to use it, while also motivating you to show up and move towards your fitness goals.
If you already know how to navigate around a gym, but just can’t seem to lock down a consistent regimen, the best motivation is to establish a specific fitness goal and develop a strategy to reach it. If you then pursue that goal with intention, you’ve already won half the battle. Hitting the gym with no real plan of attack is like trying to drive a race car when you haven’t even learned to drive yet. I firmly believe in the power of specificity, structure and accountability, because all of those elements provide a blueprint for you to follow.
Here is a step by step guide to developing a successful fitness overhaul.
1. Convince yourself that you WILL reach your fitness goals.
2. Print out images of people who have the kind of body you want and put them on your fridge or another prominent place you will see daily.
3. Give yourself a deadline.
4. Make your goals REASONABLE. Don’t put down, “I will lose 60 pounds in 30 days”, but pick a more reasonable goal, like losing 3 pounds per week.
5. Develop a workout schedule and stick to it.
6. If you don’t have a clue what to do while at the gym, hire a personal trainer.
7. Take progress pictures every week to monitor your progress.
8. Follow a specific meal plan to keep you on track.
9. If you have a setback, pick up where you left off. We are all human and have “off” days.
10. Don’t be intimidated by seasoned gym members. Most people are willing to help you if you have a question about how to operate machines.
11. Learn gym etiquette. The pace of a gym is rapid, especially during peak hours, so you need to be aware of concepts like “working in” (people will ask you if they can take turns with you on a machine or station). Don’t sit on benches unless you are actually exercising on them. Wipe down equipment if you sweat on it.
Now get off your computer and get serious about your goals!

Don’t Bust Your Diet This Holiday Season!
Here is a repost of an article I wrote last November. It’s that time of the year again for holiday foods, so beware!
It seems that I will continue to uphold my yearly tradition of making my incredible (and incredibly UNclean) fudge for the holidays, as well as my signature turkey stuffing. Since the holidays come only once a year, it seems reasonable to indulge a bit, right? Well, if you’re a fitness fanatic and you have competitions coming up like several of my friends do, you can’t exactly throw caution to the wind and consume whatever you want. However, you CAN still indulge in small amounts of rich foods which are not considered clean as long as your other foods are healthy and clean. This means that your abs don’t have to hibernate during the holidays!
There are a few tricks to minimize the amount of bad foods which you may be tempted to devour. You can consume a small amount of lean protein right before you have a carb cheat. This will slow down digestion so that the carbs aren’t stored as readily. Another trick is to drink at least eight ounces of water before you indulge in a decadent treat. This will help to fill you up so you consume less food afterward. When you are aware that you will be at a function in which tempting foods will be around, make sure your meals beforehand are kept clean and that you you eat every 2-1/2 to 3 hours to ensure that you won’t be ravenous come party time.
A newer tactic which can often work wonders for some people is to practice an intermittent fast the day before in which you consume a small number of calories, say 400-500, then go to town on turkey day, consuming your maintenance calories then. This seems to work better if you ramp up the week before with a series of intermittent fasts in which you consume your food (maintenance calories +10-20% on training days, then drop to -20% of maintenance on rest days) within a 4 to 8 hour window, then fasting the rest of the time. If you do this, crank up your protein intake so that it is at least 1 gram per pound of body weight. I personally love this diet approach and my body responds well to it, plus I can enjoy all the goodies on Thanksgiving without remorse.
There are food choices which are cleaner than others during the holidays. Though common holiday foods are rather calorie dense, here are a few food items which are lower in calories and fat:
- Roast turkey breast
- Green beans without butter
- Mashed potatoes made with whipped butter and Greek yogurt instead of milk and regular butter
- Pumpkin Pie
I know some of you are assuming that my cats join in with holiday feasts, but I always put them in my bedroom and lock the door. There are several reasons why I keep my felines away from the holiday table:
1. People food can often be hazardous for animals
2. My cats will run underfoot and probably trip people
3. My cats will suddenly forget the rule about not jumping onto tables and will create an unsanitary environment for guests
4. My cats will turn into pesky little beggars
Some of you may also be wondering what I am planning on cooking and eating, so here is my Thanksgiving menu:
- 16-18 pound turkey
- my secret stuffing recipe which has lots of goodies in it, but is relatively low in fat and calories compared to other exotic stuffing recipes
- mashed potatoes made with light butter and sour cream
- green bean casserole
- my homemade fudge
- whole cranberry sauce
- turkey gravy
- wine
- store-bought pumpkin pie
Obviously there are some items on my menu that fall outside of my “clean food guidelines”, but since the holidays only come once a year, I have no qualms about it. This is the time during which we should count our blessings and spend quality time with the people we love without getting anxious about what we are eating. However, this does not mean you have free license to go nuts on bad foods for the next month! If you end up indulging in other foods, don’t beat yourself up. Instead, enjoy the feast and resume healthy eating the next day.
Happy holidays!
Click Coffee and Protein Review
Please check out my review of Click’s All-In-One Coffee and Protein Drink Mix review! I’m not kidding when I say this product is DELICIOUS! It also mixes well, and provides 16 grams of protein in a mere 120 calories.
This all-in-one coffee and protein drink mix is a delicious beverage!
IMPORTANT NOTE: I mixed the cold version in a blender bottle with a wire mixing ball. If you decide to microwave such a container, it is CRITICAL that you REMOVE the metal ball and vent or take the top off!!!
A better option is to pour the mixed cold beverage into a microwave-safe container and then heat it up.
BRAVO!
Proper Breathing Mechanics During Weight Training (Repost)
Now that I have been weight training for over 25 years, I have an intuitive sense of proper breathing mechanics when I lift weights, as many seasoned gym beasts can also attest to. However, those of you who are not as experienced or comfortable around a weight room might not know how to breathe properly.
The basic concept is that you will EXHALE on the exertion phase and INHALE on the relaxation phase of the exercise.
Let’s use the wide grip lat pulldown exercise as an example (which incidentally should be performed so that you bring the bar to your upper chest and NOT behind your back). You will exhale as you pull the bar down, then inhale when you return the bar to the starting position.
Most exercises can be performed using this basic technique, but if you are lifting very heavy weights, or even lifting heavy boxes, you can employ a breathing technique called the Valsalva Maneuver, in which you inhale deeply, then hold your breath while lifting the weight. This increases intra-abdominal pressure and thug confers support to the back. However, if you have high blood pressure, this movement can cause your blood pressure to skyrocket. Other relatively common symptoms which can occur during the Valsalva Maneuver are dizziness and fainting. As an alternative, you can simply contract your abdominals, keeping them tight, and continue to breathe normally during the movement.
The Social Media T and A Show
Social media is pretty much here to stay, as evidenced by the worldwide participation which has emerged. Truth be told, it can be fantastic way to build a brand and to advertise products and services. However, social media has also provided very easy access to smut and porn of all degrees (I’m guessing at the extent here, since I have no idea how far that river extends). My belief is that as long as no one is getting hurt or bullied, all is fair and that the more salacious profiles should be able to do their thing. Seriously, if that’s your thing, then rock on.
However, this post is about the so-called “above board” profiles whose admins are young fitness women and men desperate to increase their following by whatever means they can. Here’s my contention: if you are truly a FITNESS person, the occasional selfie which features your ample bosom or buttocks seems reasonable, but if you are littering your Snapchat or Instagram account with images of your big fake twins (either pectoral or down south) and proclaiming that you are just trying to spread the love, you’re not fooling anyone. Guys are surely sending their “love”, and certainly not in a proper or flattering way. Why would you even take pride in growing numbers of followers if you know that you are only building an online spank bank for creeps?
I understand that some men are so creepy that they’ll get off on images of models in bras from a 1954 Sears catalog, but if you are posting pics of yourself bending over bare-assed, you are truly asking for attention from the least savory members of society. And if that’s the case, shame on you. The only value you have when you consistently post scandalous images of your barely-clothed body is as a hot piece of ass, and certainly not someone with any authority or intellectual merit, even if you hold three doctorates and have won a bunch of academic awards.
I’m not saying you can’t be sexy, but there is a lot to be said for leaving something to the imagination. If you are revealing any part of yourself which might only otherwise be revealed behind closed doors to the object of your lust, you’d better think twice about what kind of riff-raff such an image will attract.
A good filter to use when you are thinking of posting an image on social media is to ask yourself, “Would I be okay with my dad/mom/daughter/son/brother/sister/grandpa/grandma seeing this image?” Try not to rationalize the response, but really pay attention to what the image conveys, as well as what kind of audience it will draw in. Another good filter is to ask yourself, “Will I be proud or embarrassed about this image in 5/10/1/20/25/30 years?”
In summary, if you are a fitness person with a social media profile which features a constant display of body parts and crevices which should only be seen by your lover, and which are not in any way related to the porn industry, you might as well switch industries. That is, unless you want to be recognized for something other than your lady humps or your baby-maker!
Ibuprofen Has Its Merits
Over the years, numerous medical studies have explored the idea that ibuprofen interferes with muscle growth, with conflicting conclusions. I know that there are some weightlifters who will take ibuprofen on a daily basis to combat numerous pain issues so that they can lift more comfortably, but this is something I would NEVER recommend. As a physician I am well aware of ibuprofen’s remarkable ability to shut down acute inflammation, but I am also aware of the risks of taking high dose ibuprofen over an extended period of time. I think it is also important to bear in mind that 1) there are different types of inflammation found in the body, and 2) some inflammation is actually necessary for optimal muscle growth.
The reason why I broach this subject is that I also know people who lift who stubbornly refuse to take ibuprofen under ANY circumstances, stating that it isn’t worth the impaired muscle growth. These people could be in agony from a muscle strain, bursitis, arthritis flare-up, tennis elbow or any number of conditions which arise from localized inflammation, yet will refuse to take anything. I will see them at the gym, struggling to move the weight that they are accustomed to lifting, only to cut their lifting regimen short or sharply reduce the weight lifted. Some of these people are so intent on pushing through the pain that they often make things WORSE and have to stop training completely until their injuries subside. Now that is just stupid. It makes far more sense to tackle the acute inflammation systemically with ibuprofen and rest the area for a few days so that one can return to full capacity, rather than risk even greater injury which essentially forces one to stop training.
I have recently dealt with a mild ankle sprain which I aggressively treated with ice, elevation, compression and high-dose ibuprofen for four days. Instead of being stubborn and refusing to take anything, I took 600-800 milligrams of ibuprofen twice a day with food, and also avoided any activities which required me to push off from my feet. I also refrained from doing any high impact moves which would aggravate my ankle. Was I concerned about adversely affecting my body’s ability to build muscle? Certainly not. Healing was my primary concern. Besides, there would have been no way that I could have trained the way I normally do while dealing with such outright pain, so it made sense to shut down the inflammatory process which was causing all the discomfort in the first place by taking the dreaded ibuprofen. I was smart about how I took it, and I did not take it for an extended period of time. Thankfully, it was a successful therapeutic treatment and I am glad I did it.
With all this said, I am still very cautious about prescribing high dose ibuprofen. The effects on the gastrointestinal tract are significant, so it is imperative to eat when taking this medication. I also caution people against taking too many doses throughout the day. A very real example occurred with a friend who was apparently taking high doses of ibuprofen (600-800 mg 4 times per day) without food for severe daily headaches. This practice resulted in a peptic ulcer which bled enough to cause her to pass out twice, landing her in the emergency room.
For those of you on the other side of the coin who have a habit of taking ibuprofen chronically, even if you are only taking 200 or 400 mg at a time, I highly recommend that you discontinue such chronic use. It is best to reserve ibuprofen for acute flare-ups.
