High Intensity Cardio Workout – The Best Bet For Weight Loss

When is the last time someone told you that a low intensity cardio workout was the best way of achieving maximum weight loss in the shortest time possible? I hear it from clients everyday. Its about 5 minutes later I go into this little routine in one form or another.
Now lets see why the leading sports conditioning trainers and fat loss coaches in the world recommend a quicker approach to leaning out your midsection.
Could you really have been steered wrong all this time? Everything you've read over the last ten years has said that when you want to lose weight fast that slow and low intensity cardio workouts are the rule.
If you dare to buck the trend and do that new high intensity interval training all you will do is burn of carbs and not experience fat loss. Right? Wrong!
If you have come this far I know I have you interested in the possibility that there must be a better approach. There is. High Intensity Interval Training may be the next big thing. I can promise you that if you keep reading you will never look at a treadmill the same way again!
First, what is "normal" slow, static, weight loss orientated cardio workout defined as? A low intensity cardio workout is when you exercise at 60-65% of your max heart rate.
Your max heart rate can be most easily figured out by subtracting your age from 220. For a person that is 35 the equation would look like this. 220-35= 185 max heart rate. Take the 60-65% fat burning recommendation and you would be shooting for a sustained heart rate of 120 beats per minute.
If that is a low intensity workout, then what is high intensity cardio workout?
High intensity cardio is defined as exercise that gets your heart rate into the 75% and up range. This can be done in a sustained fashion but not for very long and that is where the interval training part comes in.
Intervals of high intensity combined with a downshift in gears to rest for 30 seconds to a minute before ramping it back up. You go fast then slower to catch your breath a little.
So how exactly does H.I.I.T. burn more fat then the slow and low method? Again, another great question! Let me explain.
Low intensity cardio training burns about 50% fat for energy while a high intensity workout burns about 40% fat for energy. So the low intensity method is best right? Just wait.
Lets take the average walker doing cardio on the treadmill for 30 minutes. Once they have finished they have racked up a calorie burn of 160 calories. If 50% of those calories are fueled by fat then they have burned 80 fat calories
Then over on treadmill number two, you have a mixed martial arts fighter doing wind sprints in the high intensity cardio style. He is doing one minute high and 30 seconds at a jog or a walk. He keeps this up for 20 minutes, is drenched in sweat and breathing like a freight train. In those 20 minutes of HIIT he has burned 350 calories.
If you take the lower fat burning percentage of 40%, what do you have? What you have is 140 fat calories burned and in less time then the low intensity person. As a matter of fact, our HIIT person is in the showers as we speak while the slow cardio workout person is getting bored out of their mind looking for something to read on the treadmill.
The bottom line is that you almost doubled your fat burning with the high intensity cardio workout, and less time to boot.
Now you can see that in the long run you actually burn more fat calories in total with HIIT then the regular style while you are doing it. What about the rest of the day?
The fact of the matter is that slow-low cardio workout only helps weight loss while you do it. Once you get off the treadmill that's all you get as far as weight loss goes after a couple of minutes rest.
Here is the clincher on HIIT. It burns calories long after you stop! It sounds too good to be true but even after you stop your interval training your body will continue to rev its metabolism for up to 24 hours depending on how intensely you did your intervals. This is a great thing for weight loss wouldn't you say?
The fact of the matter is that even after you hit the showers and are sitting on the couch, HIIT is still working towards your weight loss goals for you. Now that's efficient. Less time spent working and longer lasting effects.
Small changes like this to your workout make all the difference when you really want to lose that weight fast. I hope that helps you out!

Natural Testosterone: The Biggest “Secret” to Keeping it Up
What's the biggest secret for a man to know in order for him to keep his testosterone up to maximum levels? We've no-doubt seen dozens of articles recommending laundry lists of foods to consume for this purpose as well as those to eschew. We've been told that good habits (like engaging in intense bodybuilding workouts) can increase this vital hormone while bad habits such as excessive alcohol consumption can diminish it. They tell us to eat broccoli and oysters and avoid eating licorice and soy. Well, we were first instructed to eat soy, but now in some corners this advice is being retracted. We were told to cut dietary fat back in the 80s and now it's recommended we don't dump too much of it because it's one of the building blocks of testosterone.
"Make sure to eat cruciferous veggies and down twelve ounces of monounsaturated fat each week and you'll be a raging bull." Are you confused? Is this all there is to it? Of course not.
The consistent intake of particular foods and the avoidance of certain others can help put the testosterone equation in our favor, but only if a more important factor is first addressed. In fact, this important determinant is so vital to male hormone health that if you've unwittingly neglected it, you could possibly double your testosterone level by simply reversing the situation. What could I be referring to? It's that ubiquitous signifier of and Achilles' heel of male middle age. It is abdominal fat; the oversized gut.
Just a few pounds of abdominal fat can cut your testosterone levels in half (1). That's not good. Considering that a healthy testosterone level is needed for everything from energy and assertiveness to a healthy heart and normal sexual functioning, it seems a lousy tradeoff for one to allow his "mojo" to be soaked up by an expanding waistline. I should know; I've allowed it to happen to me in the past. And the return of virility and vitality after shedding my nearly 40-inch mid-section surpasses any fleeting pleasure I'd gotten while inadvertently forgoing my ability to look down and see my feet.
In order to understand how abdominal fat can hinder one's testosterone production, you must have a basic understanding of the �loop feedback' mechanism by which natural testosterone is regulated in the male body. Testosterone is produced by the leydig cells in the testes, but only after a signal has been sent there by the hypothalamus in the brain. That signal is sent via intermediary hormones called LH (luteinizing hormone) and FSH (follicle stimulating hormone). The LH and FSH are sent when the hypothalamus gets a reading that testosterone levels are getting too low. Of course, the hypothalamus reduces its LH and FSH release when testosterone levels reach the upper level limit. This loop feedback system serves the purpose of keeping the body in hormonal homeostasis.
This all seems simple enough until an antagonist is thrown in the mix. That antagonist is the female hormone; estrogen. Yes, men's bodies are designed to require some estrogen. However, we guys aren't supposed to have a whole lot of this stuff and it just so happens that we get it from the conversion of some of our own testosterone (2). That's right � the simple elimination of a molecule here and there from the molecular structure of testosterone and � Surprise� you've got the female stuff. It's okay when the ratio between �test' and �estro' is large. Things go downhill as the ratio shrinks.
So what do we mean by "downhill"? Well, consider this; when the hypothalamus takes its reading to find out whether testosterone is sufficiently high and thus reduce its output of LH and FSH, it can't always distinguish between estrogen and testosterone in the receptor sites (3). That means I could have a subpar testosterone level yet my hypothalamus might read it as being sufficient or even high due to estrogen that's occupying the receptor sites in my body. So my libido and overall health could be in dyer need of a testosterone boost, but the signal that would make things happen is being smothered by estrogen. That's not a pretty sight. (no pun)
And what can cause these high estrogen levels? You guessed it; body fat. A hormone called aromatase is what does the conversion and this stuff increases as body fat levels go up. In addition, testosterone levels tend to be knocked down even further by high insulin levels which are a side-effect of the particular type of fat that accumulates in the abdominal region.(4)
So here's a typical list of things to do that can increase your natural testosterone production:
�Eat cruciferous vegetables
�Avoid excessive alcohol consumption
�Consume fish oils
�Take a zinc supplement
�Engage in intense exercise (strength training)
�Increase flavenoid intake
Just remember; these steps will probably be extraneous at best if you've allowed an "estrogen factory" to begin forming between your ribcage and hips. The biggest key to higher testosterone is to lose the gut. When your waistline is slim, these other steps will have a more powerful and "potent" effect.

Weight Loss and Appetite Control with Hormone Balancing Therapy
Your endocrine system is comprised of several glands which direct activities within the body by releasing chemical messengers, called hormones, into the bloodstream. The target cells for each hormone require the presence of that specific hormone in order to carry out their own functions.
Overweight individuals may have one or both of the following conditions:
1. Endocrine Gland Dysfunction - The glands themselves aren’t functioning right, perhaps necessary coenzymes aren’t being supplied or tissue has been damaged from inflammation. This causes your endocrine glands to secrete too much or too little of certain hormones.
2. Target Cell Hyper or Hyposensitivivity - The lines of communication in your endocrine system aren’t functioning right. Tissues and organs which are supposed to respond to your hormones are either responding too well or not well at all. This sends confusing signals to your endocrine glands that now think they need to stop sending hormones out or else send out a lot more.

Either of these conditions results in levels of hormones that are out of balance, and can be the original cause of weight gain or the unfortunate result of excess weight. In either case, the logical step toward optimal health is to assist our bodies in regaining a balanced, normally-functioning endocrine system.
When most of us think of “correcting hormonal imbalances†we think of HRT- Hormone Replacement Therapy in postmenopausal women. Yet the hormones used in HRT make up only a small percentage of the more than fifty hormones which regulate our mood, our metabolism, our sexual function, our growth and development, and other functions.
Research into the hormones involved in obesity is actively underway, but there is currently no HRT for the hormone imbalances that are causing weight gain, water retention, and difficult weight loss in your body. Yet, the absence of this treatment option may not be as disheartening as it seems.
HRT for obesity could likely prove to be a very imperfect solution to these hormonal issues. Crucial lessons can be learned from postmenopausal HRT which has been fraught with difficulties, being largely ineffective or causing highly undesirable side effects, and in some women even promoting the development of certain cancers.
Research and clinical experience is showing that we cannot apply one general hormonal treatment to all people and expect it to work for each of them. In response to these difficulties, the current trend in HRT is to treat women with individualized, or “bio-identicalâ€, hormones based on an analysis of the specific hormonal imbalances in their system.
However, the specific imbalances in each person changes over the course of treatment requiring frequent re-evaluation of the situation and alteration of the HRT concentrations and dosages. Therefore, the effectiveness of even individualized HRT is questionable in light of the expense, as well as physical and mental stress, involved with the treatment.
The complications of postmenopausal HRT reveal the unlikelihood of truly successful “obesity HRTâ€. Allowing doctors to prescribe large doses of hormones or even treating ourselves with phytohormones may be largely ineffective, dangerous, or both, and is obviously not the best option.
The absolute best option is for our bodies to regain their own regulatory control of hormone production and to rebalance their own cellular sensitivity to levels of circulating hormones. Ideally, weight loss should be achieved by safely and naturally assisting our body in regaining a state of optimal health.
A well-balanced diet, regular exercise and adequate stress control are weight loss basics that have a huge healthy impact on your endocrine system. Other natural approaches include iodine supplementation if you suspect subclinical hypothyroidism or adrenal gland or licorice supplementation if you suspect low-functioning adrenals. Both endocrine conditions are commonly associated with obesity.
Another natural, useful approach is homeopathy. This healing modality is gaining popularity because of its gentle, restorative capabilities. The following list contains official homeopathic hormones and glandulars. These ingredients should be included in homeopathic weight control and appetite control products that are designed to correct endocrine dysregulation and hormonal imbalance.
Thyroidinum (Thyroid): Indicated for excessive obesity. Thyroidinum provides a general regulation of carbohydrate, protein, and fat metabolism through its influence over the organs of nutrition, growth, and development. Effective relief for metabolic disorders, muscular weakness, and sugar cravings.
ACTH (Adrenocorticotropin Hormone): Indicated for appetite irregularities, excessive mental and physical sluggishness in the morning, hypothyroidism, and excessive thirst, increased excretion of calcium and phosphorous, muscular weakness, and swelling and edema of the extremities.
Cortisone: Indicated for fat and water retention, tendency to hypothyroidism, and rhythmic disorders of several glands: pituitary, adrenal, pancreas. For individuals with a tendency to obesity with retention of water, dry skin and mucous membranes, acne of the face, shoulders, and back, diminished sexual desire, and/or restless legs.
Hypothalamus: Indicated for the oversensitive individual with depression linked to stress or physical issues. This remedy is effective in issues of thyroid malfunction, water retention, and obesity. Also indicated for disturbances of the appetite and circulatory malfunction.
Adrenalinum (Adrenaline): For relief of increased appetite, apathy and lack of ambition, loss of strength, general marked anemia, and belching after meals.
Pituitarum (Pituitary Gland): Stimulates muscular activity, regulates reabsorption of water at the kidneys, treats atrophy of the breasts, and alleviates gallbladder inflammation [often linked with obesity]. Effective in the relief of back and neck ache, night time anxiety, difficult mental concentration and obsessive thoughts.
