Burn Fat With Brown Fat

Sounds intriguing doesn't it to burn fat with brown fat.

What is brown fat?

Brown fat in contrast to white fat has a higher number of mitochondria, which makes it brown. Its primary function is to maintain and generate body heat. It especially helps infants, which have a larger amount of brown fat than adults, to stay warm. It has been recently found that brown fat resembles skeletal muscle rather than white fat. It is also in skeletal muscle that brown fat can be found in adults, especially in the neck and chest areas.

To produce energy, brown fat burns white fat for fuel. That is why there is much interest in medical research to understand how to make more brown fat and activate it to help us burn white fat, which is partly responsible for obesity, heart disease and cancers.

Hormone That Links Exercise To Health Benefits

New research led by a group at Dana-Farber Cancer Institute, has found a chemical messenger that links exercise to health benefits throughout our bodies. They call this hormone Irisin. Irisin is located in the outer membrane of muscle cells and signals the activation of the metabolic regulator PGC1-alpha. Their research has found that prolonged exercise increases the levels of irisin and activates PGC1-alpha. The result of increased irisin levels is better control of blood sugar and insulin levels and a small amount of weight loss.

They also have found that increased levels of irisin also switches on genes that convert the bad white fat into good brown fat. The one thing that irisin does not do is make muscles stronger, however, Only exercise can give you that result.

Conclusion

We now know how to make more brown fat with exercise and increased levels of irisin. However, switching on the brown fat to burn white fat is still difficult. Cold temperatures switch on brown fat. That may be why I find it easier to control my weight in the winter months. I always seems to gain a little in the summer months, even though I'm more active. But, I doubt that many of us are willing to sit in a freezer for an hour everyday to switch on our brown fat to start burning white fat. So, the search is still on to learn an easy method to switch on our brown fat. For now, exercise is still the best way to burn that bad white fat in our bodies.

What is Fatty Liver Disease?

Fatty liver disease involves the accumulation of fat, especially triglycerides, in liver cells. If excessive use of alcohol is not a factor, then this disease is called nonalcoholic fatty liver disease or NAFLD. Generally, you may have NAFLD if the amount of fat in your liver is more than 5 to 10 percent of your liver's total weight.

Fatty liver is the initial phase of NAFLD and typically does not involve liver inflammation or liver scarring. Patients can have fatty liver for many years or even decades without serious medical implications. However, if left untreated, fatty liver can develop into a more serious phase of this disease.

Some patients with NAFLD develop the second phase of this disease known as nonalcoholic steatohepatitis of NASH. NASH is the accumulation of fat in liver cells along with liver inflammation. Again, if left untreated, this phase can cause liver scarring. Eventually, it can lead to irreversible scarring known as cirrhosis of the liver. When this occurs, your liver can no longer function properly and can develop into liver failure, liver cancer or liver related death.

However, if you undergo yearly physicals, your doctor can detect NAFLD in its early stages. Patients typically experience no symptoms in the early stages of this disease, and may be surprised to learn that they have NAFLD. But if patients do experience symptoms, they may have a dull ache just below their ribcage on their right side. Other symptoms that they may have are:




  • Nausea


  • Weight loss


  • Fatigue


  • And an enlarged liver.



Research indicates that a change in diet and exercise routine can reverse this disease in its early stages.




Losing weight is will also help stop and reverse fat accumulation in your liver. However, the weight loss must be gradual. Sudden and rapid weight loss can actually make NAFLD worse by causing liver inflammation. Patients should target a weight loss goal of just 1 or 2 pounds a week.



Guidelines for improving your liver health include:




  • Not abusing alcohol


  • Not abusing medications and drugs


  • Not eating food high in saturated fats


  • Not eating foods high in sugar content


  • Staying away from highly processed foods like bleached flour, white bread and white rice


  • You should exercise regularly and stay physically active


  • Don't smoke


  • Eat whole grains and brown rice


  • And get adequate amounts of choline in your diet to help prevent fat accumulation



Stay fit and trim, stay physically active and eat properly, and follow your doctor's instructions for insulin resistance and diabetes, and you will not have to worry about fatty liver disease.

Why You Should Lose Belly Fat

Why should you lose belly fat?

It is actually visceral fat that is the health concern. Visceral fat is the fat layer that lies under the layer of abdominal muscle. This fatty tissue surrounds our organs, and is the cause of giving us that "beer belly" physique. Research has shown that excessive viseral fat can lead to some
serios health concerns.

Below we will explore

  • Why Visceral Fat Is Dangerous To Health

  • The Proper Diet To Lose Stomach Fat

  • Proper Exercises To Lose Stomach Fat

Why Visceral Fat Is Dangerous To Your Health

Visceral fat cells are more than just stored energy. They can produce hormones that can negatively affect your health.

These fat cells can contribute to the development of breast cancer by producing estrogen. Visceral fat cells can also help develop type 2 diabetes by producing insulin resistant hormones. Research has also shown that an excess of visceral fat around your waist is associated with
and increase risk of

  • Diabetes

  • Breast Cancer

  • Gallbladder Problems

  • High Blood Pressure

  • Heart Disease

  • And Colorectal Cancer

How do you know if your waist is too large?

Measure your bare waist just above your hip bone with a soft tape measure. Don't hold in your stomach or hold your breath as you measure yourself.

You should find ways to lose belly fat if your waist is larger than 40 inches for men, and 35 inches for women. If your waist size is too large according to these guidelines, you need to lose belly fat to reduce your risk of developing some of the diseases listed above.

Happily, visceral fat responds well to a good exercise routine and diet plan. A good exercise routine and diet plan becomes even more important as we age when our physical activity and metabolism slows.

The Proper Diet To Lose Belly Fat

Basically, centering your diet around whole and minimally processed grains, fresh vegetables and fruits, legumes, nuts and seeds will help your achieve your goal to lose belly fat.

More importantly, you should stay away from these foods:

  • Enriched Flours

  • Bleached Flours

  • Foods with added sugars

  • High Fructose corn syrup

  • Junk foods and snacks

  • And hydrogenated oils

An added way to help yourself lose stomach fat is to use these tips to speed up your metabolism:

  • Frequently drink cold liquids

  • Keep yourself hydrated

  • Eat 5 or 6 small meals throughout the day rather than eating just 1 or 2 large meals

  • Eat more lean protein rich foods

  • Drink green tea or black coffee without added fat or sugar

  • And use hot peppers with your meals

Proper Exercises To Lose Belly Fat

Use full body, multi-joint exercises to lose belly fat. Ab specific exercises like situps and crunches do tone muscle, but don't burn fat. Full body exercises on the other hand burn stomach fat by increasing your metabolism and fat burning hormone production. Full body workouts accomplish this by working many large muscles groups and your cardiovascular system all at the same time.

A few examples of full body exercises are:

When doing an aerobic exercise, use an Interval Training technique rather than a constant speed and intensity technique. Interval Training involves rotating between a slow speed and intensity and a high speed and intensity cycle. For example, rotating between walking at 4 miles per hour for a minute and a half, then running at 6 or 8 miles per hour for a minute is one possible cycle. You can repeat this cycle for an excellent 20 minute Interval Training workout. Research has shown that Interval Training actually burns more calories and gets you into good physical shape faster than a constant speed aerobic routine.

In summary, losing stomach fat involves switching to a healthy diet plan and a good exercise routine. Otherwise, you run the risk of developing some serious medical problems that can be avoided with some simple lifestyle changes.

Eating Nuts Reduces Total Cholesterol and LDL

In a recent press release, a new study shows that eating a third of a cup of nuts a day can reduce total cholesterol by 5.1 percent and LDL levels by 7.4 percent. Also, the ratio of LDL to HDL cholesterol was improved by 8.3 percent, and caused a decrease in triglyceride levels by 10.2 percent.

The results were reported by researchers at the Loma Linda University School of Public Health in California after analyzing data on 583 men and women who had participated in 25 nut consumption trials.

Even though most nuts will produce the same beneficial results, the best evidence for the beneficial effect came from the studies of walnuts and almonds.

Exercise Doesn't Lead To Weight Loss



In the article "Why Doesn't Exercise Lead To Weight Loss?", which is a summary of a report in the British Journal of Sports Medicine titled "Beneficial Effects Of Exercise: Shifting The Focus From Body Weight To Other Markers Of Health", it is shown that exercise has many health benefits, but does not usually lead to weight loss.

The main reason is that most people do not change their eating habits. The formula is simple. If you eat more calories than you use for energy, you will gain weight. If you eat as many calories as you use for energy, your weight will remain the same. To lose weight, you have to take in less calories than you use for energy.


30-minutes of running only uses about 300 calories (Calorie Chart). This can easily be replaced with one Gatorade.


However, exercise can burn away fat, but must be in combination of a proper diet. Believe it or not, a low intensity exercise will burn a higher percentage of fat calories than a high intensity exercise. According to the report, heart rates between 105 and 134 beats per minute represents the fat-burning zone. Some of the Benefits To Exercise are:


  • Decrease in blood pressure
  • Decrease in your resting heart rate
  • Decrease in the "bad" cholesterol and an increase in the "good" cholesterol
  • Increase in your body's ability to deliver nutrients to your tissues
  • An increase in your body's ability to remove toxic waste from your tissues
  • And an increase in longevity and overall health
