Ephedra Plus Caffeine Ultimate Weight Loss Combination

Chinese ephedra (ma huang) comes from the dry herbaceous stems of a primitive family of plants known as ephedracae. Three species of ephedra are grown in China and recognized in the pharmacopoeia of the People's Republic Republic of China and the Chinese material Medica. This herb is one of the oldest and most widely used Chinese herbs. Ma Huang has been used for thousands of years in traditional Chinese medicine as a primary component of multi herb formulas that are prescribed to treat bronchial asthma, cold and flu, coughing, and wheezing, fever, chills, lack of perspiration, headache, and nasal congestion. It has, therefore, been no secret to the Chinese that there are a diversity of significant benefits to be derived from the other approximately 99% of ephedra plant that does not contain ephedrine alkaloids.

Thanks to modern science and proprietary nutraceutical know how, Hi Tech has now mastered the specifics of these beneficial ephedra constituents, which have been isolated, extracted, and standardized to create Hi-Tech's Thermo-Z brand of ephedra extract for its remarkable benefits in weight loss dietary supplements.

Ephedra + Caffeine: The Holy Grail of Weight Loss

The weight loss benefits of ephedra have been known for centuries. In fact, studies show that ephedra + caffeine can more than double the rate of weight loss compared to a placebo. Recent developments in the field of weight management have demonstrated the efficacy of using pharmacological agents, both instead of and in addition to, diet and exercises. Specifically, many studies have focused on the effects of increasing sympathetic nervous system stimulation in order to increase basal metabolic rates, thereby providing a long term therapeutic option for thermo genesis. Because low metabolic rate is a characteristic of being overweight, and sympathetic activity has been shown to increase this metabolic rate, a role for sympathetic stimulation in the field of weight loss has a well established physiological rationale. Unfortunately, however, the economic advantages of synthesizing and marketing these treatments have rapidly overshadowed the need for adequate research to assess their efficacy and safety.

Most of the early investigations on the use of ephedra, caffeine, and aspirin (ECA) combinations concentrated on the effects of ephedra and caffeine stimulate weight loss by increasing the sympathetic nervous system. Both ephedra and caffeine stimulate weight loss by increasing the sympathetic tone of various resting tissue beds, notably fat. It has been shown that both ephedra and caffeine (lesser degree) are capable of mimicking a sympathetic response when given alone. However, when given in combination, there is a synergistic increase in the level of thermogenesis, such that the stimulated levels are greater than the added sum of the separate effects of caffeine and ephedra given alone. The exact mechanisms of this enhanced action are still being researched.

Why Metabolism is Important

Read through any diet success story and you will see the true secret to that person's success. At some point, the person always integrated exercise into their plan. The same holds true the other way around. How many times have you heard someone say that they work out all the time, but just can't seem to lose those last ten or fifteen pounds?

The truth is, in order to achieve lifelong results, nutrition and fitness need to go hand in hand to optimize your metabolism.

What is Metabolism? Metabolism is the process your body uses to break down the food that you eat, convert it to energy, or store it. Your metabolism is based on several cues that you give your body by the way that you eat and the energy you use in your daily routines.

To achieve lifelong fitness, you need to raise your activity level to start burning more calories, while feeding your body the right amount of food to sustain itself. That means eating enough throughout the day to let your body know that there will be plenty of food around to sustain a higher caloric burn. Once your body acclimates to both of those signals, your metabolism will start to change. You will be burning more calories by increasing your activity level, but you will also increase the amount of calories you burn when you are not working out - while you work, watch television, and even when you're sleeping.

Understanding your metabolism is the reason that low calorie diets don't work. When you feed your metabolism your body burns more calories. A great example of this is on a weight loss network tv show that the people who won't follow their eating plan and kept eating less calories actually gain weight. Your body will burn fat as your main source of energy if you eat 5 small meals during the day balanced with the proper calorie range.

One thing to keep in mind is that the faster your metabolism gets and the more fat you burn the more you need to eat. This concept is one of the hardest for people to understand which is evidence why 60% of Americans are overweight or obese. Without increasing your calories as your metabolism increases you burn away your new muscle tissue for energy which keeps you staying at the same results no matter how hard you workout.

A Fit Body Burns Calories and Loses Weight- Pretty Simple

A common strategy for people trying to lose weight is to focus on calories, so they make calorie burning the biggest aim of all their workouts, with the added goal of being in the "fat burning zone". See our new page on The 7 Steps to New Year's Weight Loss. People often do very long and repetitive cardio sessions — walking or jogging for an hour or more at a relatively low, even level of intensity. But this isn't necessarily the most efficient way to burn off unwanted fat, and it's certainly not the most effective way to achieve and maintain a strong, lean body over time.

To do that, you need to boost your metabolism, which regulates your body's ability to become (and stay) lean. And shifting your metabolism depends on improving your fitness and supporting your goal with good nutrition, which is 70% of your ability to get the results you want.

When your body turns food and oxygen into energy — something it does throughout the day, virtually all day — it burns calories. That process takes place in your cells' mitochondria, which need oxygen to burn those calories efficiently. So the more oxygen your body is capable of processing per minute (a function of your VO2 max — more on that in a moment), the more calories it can grind through on a given day.

In other words, being fit helps your body run more like a finely tuned machine — one that's naturally inclined to eliminate excess weight.

"People who have a higher level of fitness burn more calories even while at rest and asleep," Hyman says. Exact numbers are difficult to nail down because each person's resting metabolic rate is unique (based on muscle mass, age, genetics and even climate). Still, some experts estimate that fit, muscular adults can burn an extra hundred calories or more per day — while at rest.

It's important to note that in the course of their daily activities and workouts, fit adults can and do burn a couple thousand more calories daily than unfit, more sedentary ones.

And here's the beauty of it: Fit people are naturally more inclined toward activity and tend to exert themselves at higher levels. That's because exercise and activities of all kinds become easier as your fitness improves, and even intense levels of exertion become more comfortable. All of which makes calorie-burning activities a much more appealing proposition, thus further increasing active inclinations.

This is what's known as a "benevolent circle" (as opposed to a vicious one) — and the more fit you become, the more you can take advantage of its fat-burning effects.

Cardio Threshold Training - Medium Intensity Days

The Plan: The threshold workout or medium intensity workout is the #1 workout that most cardio athletes and enthusiasts miss in their programs. The goal of the threshold workouts is to work at the max at which your aerobic metabolism produces energy. Because you have another energy source called your anaerobic metabolism, you have the ability to train harder or faster than a proper threshold workout. Most people thinking that they need to be killing themselves to be getting a good workout never slow down enough to train their body effectively.

Your aerobic metabolism is the way your body burns fat and carbs as energy with the use of oxygen. The only way to optimally perform in cardio or endurance races, as well as, achieve your weight loss goals is to train your aerobic metabolism to be as fast as it can. The perfect workout for weight loss, 5k training, and running a marathon.

After effective threshold workouts, the biggest difference you will instantly feel is how much faster you perform at lower heart rates. Your heart rate profile will change as you progress and improve. This is why it is so important for a cardio expert to be monitoring your progress and making adjustments. You now have the ability to run faster for the same distances and times that were once a struggle.
