Human Growth Hormone Secretion

Synthesis and secretion of HGH is controlled by many factors such as exercise, nutrition, sleep, stress and sometimes even by growth hormone itself. The control, however, are wielded by two hypo-thalamic hormones (Growth hormone-releasing hormone or GHRH and Somatostatin or SS) and one hormone present in the stomach (Ghrelin).

Functions of HGH

Human growth hormone contributes in the building up of the human body. HGH has two different types of effects on the human tissues and the human system as a whole direct and indirect. The direct effects are the upshot of the growth hormone binding its receptor to the target cells. Indirect effects are stimulated by an insulin-like growth factor-I (IGF-I), a hormone secreted by the liver and other tissues in response to growth hormone action. In fact, most of the growth promoting effects of HGH are the consequence of IGF-I acting on the target cells.

Thus, it is apparent that HGH or Somatotropin plays a vital role in major physiological processes, including growth and metabolism.

HGH & Growth

The major role of growth hormone in effecting body growth is to stimulate the liver and various other tissues to secrete IGF-I. IGF-I. This, in-turn, it provokes proliferation of Chondrocytes (cartilage cells), resulting in bone growth.

HGH & Metabolism

Human growth hormone has been found to have important effects on protein, lipid and carbohydrate metabolism. These effects in some are direct, others indirect and a few showing mixed effects.

Although height growth is an all-too-manifest effect of HGH on the human system, it has several other specific and essentially functions. These functions range from protein synthesis to building muscle mass, calcium retention to mineralization of bones, stimulating the immune system to maintaining fuel homeostasis, etc.

This is all about real human growth hormone. Biosynthetic human growth hormone, also known as recombinant human growth hormone and abbreviated as rHGH was first used for remedial use in the U.S. in 1985. Since then, the biosynthetic variety of HGH has nearly sidelined the pituitary-prompted human growth hormone, especially in therapeutic use.

But theres also a lot of pressure on dinner. Its the last meal of the day and if you are lacking important nutrients in your diet that day, you have an opportunity to make up those nutrients in your evening meal. But you dont want your meal too heavy or you might not sleep well. Conversely, eating too little will not only likely leave you lacking in nutrients, but could also leave you ravenous for breakfast 12 hours later.

So how do you make sure dinner is a balanced, nutrient-packed meal? Plan, and plan some more. Although we are more likely to spent time preparing dinner versus other daily meals, its also a meal that can easily get derailed. You plan to grill chicken breasts and vegetables, but then belatedly remember your son has a baseball game or its open house at school. So its chicken nuggets all around.

Planning keeps you in synch with your schedule. If you plan a weeks worth of meals, you can think about the various obstacles you might find that week in actually bringing your plans to fruition. You can plan a quick pasta salad on open house night, and healthy, veggie-packed sandwiches on baseball night. This keeps you out of the fast food lane.

What are some other tips for planning healthy dinners?

*Dont cook separate meals for picky children. If you know that your salmon and sauted spinach will also result in you making mini hot dogs and fries for the kids, you might rethink it, not having the time or energy to make two completely separate meals. Then you suffer, and they do as well. Its important to expose your children to a variety of foods, so make the salmon and spinach. Be sure to offer applesauce, whole wheat bread and some fruit. Then everyone gets a healthy meal and your children just might surprise you by actually eating some of the adult meal.

*On weeknights, stay away from involved meals. Think of things that can be prepared in less than 45 minutes, though its ideal to keep your meal prep to 30 minutes whenever possible.

*Do as much prep as you can ahead of time. If youre planning grilled chicken and vegetables for dinner, say, then you can clean and slice your vegetables in the morning before you head out for the day. Marinate the chicken. In the evening, all thats left is tossing a quick bag salad and grilling your meat and vegetables. This saves on clean-up time as well.

*If you must eat out, apply the golden rules for restaurant eating: Stay away from white or heavy sauces, order oil and vinegar to dress your salad, and eat only half the entre, pack the rest and enjoy it for lunch the next day.

Male pattern baldness is often genetic and/or related to too much dihydrotestosterone (DHT) in the follicles of the scalp. This is a specific type of testosterone that is only found in hair follicles. For years, saw palmetto oil has been used to treat prostate problems, and it has been found to have some beneficial effect in blocking the DHT that causes most male hair loss.

A good multivitiman containing B5, folic acid, silica and biotin will help maintain hair health, but be sure to regulate your dosages carefully. Taking in excess of 30mg of zinc daily can cause a copper deficiency, often linked to hair loss. Before supplementing copper, restrict your intake of zinc, as copper can become toxic.

Traditional asian medicine links hair loss to kidney malfunction and often prescribes a kidney tonic to correct male hair loss. Another ancient remedy is aromatherapy and the use of essential oils. A combination of rosemary, thyme, lavender and cedarwood was studied in Scotland and the results were encouraging. The essential oils were mixed with a carrier oil, either almond or grapeseed oil, warmed and then rubbed into the scalp. The treatment was continued with a warm head wrap. Used for several months, the tonic helped over 40% of the studys participants regrow hair.

Perhaps the easiest natural treatment for male hair loss is a change of diet. Increasing foods rich in iron and silica seems to help strengthen the existing hair and encourage new growth. Consider adding foods rich in silica like potato and cucumber skins, peppers and sprouts.

In todays overly medicated society, many are hesitant to try another prescription drug. You have a choice not to. Many of the natural hair loss treatments are pleasant and more often than not, have no side effects. You may be pleasantly surprised at the results.

I had planned to do a detailed review of the Landice L7 Executive treadmill today, but Mrs. Sensei has laid down the law and I only have a few minutes to post a review on this fine July 4th holiday — the DOJO itself is empty and all of the other senseis are off work and at home enjoying their families. Look for the full review tomorrow, but for today enjoy a quick rundown of the differences between the numerous models of Landice treadmills out on the market.

If you’vee spent time looking at Landice treadmills then you’ve probably noticed they have a large number of units available and the differences between them aren’t always as obvious as they should be. Here is a guide to comparing the different models, full commercial and light commercial.

At each level (L7, L8 and L9), the only difference between a Pro Sports Trainer, a Cardio Trainer and an Executive trainer is going to be the console. The Landice Pro Sports Trainer Treadmill has the lowest end, basic display, and the Landice Executive treadmills have the highest end (really spiffy, if you ask me) displays. The difference in the consoles is very obvious upon viewing.

The differences of each Landice treadmill level (L7, L8 and L9) is going to be the size of the rollers and the length of the deck. The higher the number, the heaver and larger the rollers and the longer the treadmill deck.

The LTD versus the Club style is an easy one as well. LTD means the unit is light commercial and Club means the unit is full commercial — meaning it is rated to run for a higher number of hours per week (full commercial usually means 100+ hours of use per week). The LTDs come in 110v and the Clubs in 220v or 110v. If you’re using a Landice Club treadmill in your home, make sure to request 110v or you may not be able to run it properly.

And there you go, the mystery of the Landice treadmills is solved!

The fact is, your body can only process about 350 calories every 90 minutes. Eat more than that, and you’re most likely overloading your digestive system. If your body cannot use all the “fuel” you provide it at any given time, it will use what it can (and only what it can), and then store the rest as body fat. It assumes, through thousands of years of experience, that there will be “lean” times when it will need those fat reserves for fuel. But in this modern age, we, thankfully, seldom face those lean times.

Because of this, if we are to keep our weight from spiraling out of control, we must, by CHOICE limit our quantities of food, as well as the KINDS of food.

So, how do we use this information in losing weight? Simple. Eat light, but eat often. There are many benefits to this strategy. First, you are only providing your body what it needs, when it needs it. Second, you are able to better maintain a consistent blood sugar level, and so you’re not left feeling tired all day.

And by making certain wise and healthful choices, you will find the 350 calorie limit CAN be quite filling. Make poor choices, however, and you’ll be left feeling unsatisfied. So be sure to choose healthful fruits & vegetables and limit your intake of breads & cereals (these calories will add up fast). Also, when including meat in the diet, choose ONLY healthful, low-fat fish & fowl.

This one simple tip, if practiced FAITHFULLY, will help you achieve your weight loss goals.

Vitamins come in two distinct types, those soluble in fats and those soluble in water. Of the major vitamins, A, D, E and K are the ones soluble in fats and Vitamins B and Care water soluble. The water soluble vitamins are not stored by the body and so these need to be topped up regularly.

On the whole, if you have a normal well balanced diet this should provide your body with the vitamins it needs, but if your diet is not fully balanced then you may need to supplement the vitamins you receive in your diet. This shows that vitamin supplements can be useful. Some of the following may suggest if you may need help with your vitamin intake.

Vitamin B12 is found in meats so this is something vegetarians need to look out for. Vitamin C and B can be lacking in elderly people. People working on night shifts could have a lack of vitamin D as your body produces this during sunlight hours. Overworked people, people under pressure and people suffering from stress could be lacking in vitamin B and C. People on diets can also have a lack of these 2 vitamins. Vitamin B can be lacking in heavy drinkers and vitamin C deficiency can be a problem area for heavy smokers as well as heavy drinkers.

The usual way to get vitamins into your body is orally. Some vitamins can be taken by injection such as vitamin B12 but it is important that this is only carried out by a fully qualified medical practitioner. By taking vitamins orally they have to pass through your digestive system and the strong acids in your stomach can destroy much of the usefulness of the vitamins so you have to ensure you take the recommended dose, not more or less, but the recommended dose.

I hope I havent spoilt your views on vitamins but you must remember that even though you may have a healthy and well balanced diet, the natural processes of your body can destroy some of the value of the vitamins you absorb. If you want to help preserve their effectiveness than eating fresh foods and only cooking foods lightly will help increase the usefulness of the vitamins.

Vitamin supplements can be used to help boost any vitamin deficiencies you may have and extra vitamins are most easily obtained, (and used), in tablet form. Vitamin tablets can either be multi vitamins or single vitamin types. The decision as to what you take is up to you, unless of course you have been advised to take a vitamin supplement by your doctor. Vitamin C is often taken in the winter and the time leading up to it. This has been shown to help keep the common cold at bay.

You must only take vitamins to help supplement a well balanced diet and do not go overboard, so take vitamin supplements in moderation. Take only as much as you need and no more, and if your diet is as good as it should be, then you may not need any vitamin supplements. You must remember that they are, as the name suggests, supplements and they are not designed to replace a well balanced diet. Be sensible and use vitamin supplements carefully.

How true? Ask yourself and do a goggle search (or a PUB Med or any advanced search of scientific articles) about how many times you see a study–any study–on a particular fruit or vegetable that comes out proving some health improvement. Not a group, but a particular fruit or vegetable. And proof of health, not disease (this is an important distinction).

We are talking about real science here not just made up stuff from some science nut or health nut. And we are talking about real fruits and vegetables like a particular apple or broccoli as opposed to a group of fruits or vegetables. In other words we are talking about something very concrete and not at all abstract–this is where real scientific study comes in very handy: such study is not abstract or it is not science. And, importantly, if I can prove it and you cannot, it is not scientifically provable. Period.

How many? Which vegetable? Which fruit?

There are plenty of promoters of eating fresh fruits and vegetables and many of them provide solid credentials like the Harvard, Tufts, Eat 5 a day, and so on (for a really good goggle search try vegetables and health or fruits and health).

For example, the Harvard site cites the latest dietary guidelines that, “call for five to thirteen servings of fruits and vegetables a day, depending on one’s caloric intake. For a person who needs 2,000 calories a day to maintain weight and health, this translates into nine servings, or 4 cups per day.” The citation for this is The USDA, the U.S. Department of Agriculture. It is a helpful abstraction but not a particular guide to particular fruits and vegetables and how they can promote your health.

But most of what these prestigious institutions promote is air–no scientific studies demonstrating the health effects of a single fruit or vegetable could be found on the Harvard site, not one. True, it’s nice air, but air nevertheless.

Now we are not talking about the genuine research on fruits and vegetables like this one listed in Pub Med, “Electron beam and gamma irradiation effectively reduce Listeria monocytogenes populations on chopped romaine lettuce”, (J Food Prot. 2006 Mar;69(3):570-4, for those who need to know) . This kind of research is not after the health promoting effects of eating, in this case, romaine lettuce. And it does not pretend to be anything other than what it is.

Of course sites promoting the health benefits of eating of fruits and vegetables could be hiding the scientific studies and don’t want to bother their visitors with all those numbers and scientific names for turnips or plums. Or farmers who grow the really good stuff and how to buy them.

I remember a study concerning folate and green leafy vegetables and some kids on an island in the South Pacific. The study, a genuine scientific study, had to be halted because the scientists found that the children in the study could not get enough folate for their diets from the fresh vegetables because the vegetables themselves were deficient. So the study stopped because, ethically, depriving the children’s diet of this essential ingredient could hurt them–especially when the science proved the children would be deficient on a natural diet. So much for the health promoting benefits of this entire group of vegetables–and I have not seen another study to refute this single isolated, particular controlled scientific study on green leafy vegetable and exactly how they promote health in humans.

So how do you know if the fruits or vegetables you eat can really promote better health? Simple answer is you don’t. But then again, if you stopped eating fruits and vegetables what would happen? Could be all those diseases they write about in Pub Med and cited by the Tufts nutritionists and become the cover story about our fat nation for Time Magazine: eat your fruits and veggies and stay healthy or until we know, for sure, something different.

Male Hair Loss Treatment: Prescription Hair Loss Medication

Male hair loss is generally regarded as natural, and not a disease. Nevertheless, many men choose to pursue the use of prescription medications as a hair loss treatment. The most popular of these prescription hair loss medications is Propecia. Propecia is the brand name of finasteride, a chemical that partially blocks the effects of male hormones that are thought to contribute to male hair loss.

While Propecia has shown some effectiveness as a hair loss treatment, it is not a natural solution to male hair loss. It requires a physicians visit for a prescription, and has sexual side effects in some users. Its effects wear off immediately upon discontinuing use, resulting in further hair loss. A one month supply of Propecia costs approximately $70-$100, making it one of the more expensive hair loss treatments on the market.

By contrast, Procerin for male hair loss is available without a prescription. It is a natural hair loss product, with no dangerous chemicals or side effects. Procerin is a safe alternative to prescription hair loss treatments. Procerin is the only all-natural hair loss solution backed by our 90-Day Guarantee.

For example you will have to consider price at least somewhat when you are looking for new and better body building equipment. You only have so much money to spend on your body building equipment and unfortunately, you cannot spend what you do not have. Even credit cards only go up so high right? Therefore, start looking for body building equipment within your budget range and you will be much better off.

It is a good idea to go into each store with a clear idea of how much money you have to spend on your body building equipment. This way you can just ask the person helping you to show you only the body building equipment that is in this price range. This will keep you from feeling bad about the great body building equipment that you cannot buy and the body building equipment that you can buy will look that much better to you as a result.

You also need to have a clear picture of what your goals are. When you are shopping in the body building equipment store ask the workers what they feel might be the best choice for what you want to achieve. They should have a good idea of what body building equipment is best for what part of the body etc.

There are many different kinds of body building equipment, there are free weights, and there are machines that are all connected as one piece. Which of these types of body building equipment should you choose for your body building needs? If your main goal is just to bulk up then you will want to choose free weights because these will be more for this type of goal. On the other hand, you will get more exercise options with a machine as your main piece of body building equipment. In addition, free weights as your main kind of body building equipment can grow to be quite the pain in the butt, as you have to take bits on and off all of the time. Ultimately, it is up to you, whichever kind of body building equipment you are most comfortable with is your best option.

Your BMI = [(yourWeight)/(your Height x your Height)] x 705

If you weight 143 lbs and are 64 in tall, then

your BMI = [(143) / (64 x 64)] x 705 = 26.2. Based on the chart below a BMI of 26.2 is overweight.

underweight, BMI = 18.5
normal weight BMI = 18.5 – 24.9
overweight BMI = 25 – 29.9
slight obesity BMI = 30 – 34.9
obese BMI = 35 – 39.9
excess obese = BMI = greater than 40

If we consider the normal BMI number to be 21.5 then you can compute approximately how much weight you should lose using the same BMI formula but by changing things around in the formula,
(your ideal Weight) = [(normal BMI / 705) x (your Height x your Height)]

For the example above if you have a BMI = 26.2 and the normal BMI number = 21.5, then,

(your ideal Weight) = [(21.5/705) x (64 x 64)] = 124.91

you should weight 124.91 lbs. That means you need to lose (143 -124.9) lbs = 18.1 lbs.

Try to get your BMI below 25. Under this number, you can expect to have good heath if you are eating the right kinds of food and exercising regularly. If your BMI is greater than 28, you are more likely to have cardiovascular diseases, diabetes, and many other diseases related to a toxic colon.

Keep track of your waistline. Your waistline, if you are a man, should be less than 35 “. For women it should be less than 30″. As your waistline get larger you become more susceptible to diseases. Of course, waistlines are going to vary because people have different shapes. But you know if your waistline to big for your shape.

Now you should know how much weight you need to lose. Beside your waistline, you should also measure bust/chest, hips, and thighs.. This gives you an indication how your body is changing. As you lose fat you may not lose weight for a while. Your body will become toned as you exercise. The weight scale does not always tell you that your body is changing and losing weight.
