There was an article printed recently in a special diet and health issue of Scientific American that covered the subject of calorie restriction and its effects on aging. It was significant to note that this article was originally done 10 years ago, yet the subject still remains new today.

Chances are, you may not have heard of the calorie restriction concept. It is based on research done with rats, fruit flies, fish and other types of creatures. The investigation started in the 1930s have shown that a reduced calorie diet can slow the signs of aging. The test subjects lived up to 20% longer and were healthier in old age than their counterparts.

Most of the diseases affiliated with aging such as cancer, diabetes, cataracts and hypertension were significantly delayed in the low calorie rats. The benefits included:

Lower body temperature

Later sexual maturation

Lower weight

Less abdominal fat
What About Humans?

Since the article 10 years ago was published, the calorie restriction field (CR) has become quite famous. In fact, there is now an organization of individuals dedicated to the CR way of life. One of the findings from the experimental investigation is that a CR diet may slow free radical production. Free radicals are what increases the .

Obviously, just reducing your caloric intake isn’t what CR is all about. It’s not a matter of limiting your fat, protein or carbohydrates. Supplementation alone with vitamins or antioxidants doesn’t work either. You’ll need to reduce the calories you consume, not the nutrients. Get knowledgeable about CR first. The link at the end of this article will give you some resources if you are curious in exploring further.

For most of us, maintaining a as a means of anti aging is not an choice we would consider. In CR, a regular meal of 1200 calories would be reduced to 940. Without the proper knowledge and guidance, one could easily become malnourished.

A Word of Warning

This article is only meant to inform about the advances made on the subject of anti aging and nutrition. In the same issue of Scientific America, there was an article on how scientists disagree on whether some amount of fat is beneficial in the elderly and another article on teenagers that starve themselves to death. The best advice is still to maintain a healthy diet and exercise regularly. The link at the end of this article will give you some healthy alternatives in the .

Into The Future…

Because of the investigation done on CR in animals, scientists are now working on an calorie restriction mimetic (in pill form) that would allow humans to get the benefits of a CR diet without feeling hungry. Isn’t technology grand?

Calorie Restriction With Optimal Nutrition (CRON) – Life Extension?

It has been know for nearly 80 years that restricting leads to an extension of life among most animal species. Many have speculated that the same principles may apply to humans as well, although it is a difficult theory to prove scientifically due to the extreme time frame required to conduct the experiment (in excess of 120 years!) Nevertheless, it is an intriguing theory which could provide many additional, healthy years to one’s lifespan.

Calorie Restriction requires that 20% – 30% less calories are consumed below the normal level eaten. For example if 2500 calories are required to maintain a healthy weight, then around 1800 calories would constitute a restricted dietary lifestyle. The other component is to ensure that sufficient required vitamins and mineral nutrients are also included in the daily diet. Naturally this requires the elimination of all junk food in favor of healthful vegetables (mostly raw), minimal lean protein sources, nuts, seeds and oils.

To begin this type of diet, one must proceed slowly. Although weight loss is not the goal here, typically the pounds will come off… be sure to limit to no more than 1 – 2 pounds per week. This is because the body releases stored toxins in the body fat as it is reduced, and losing too rapidly can provide a toxic overload to the body.

Once you have followed a health eating pattern for a minimum of two weeks, you will no longer crave the sugars, fried foods and fast foods which make up the typical Standard American Diet (SAD). The most important part of this eating style are the biochemical alterations which immediately occur in the body. Lipid profiles alter toward lower cholesterol ratios (HDL-C to Total Cholesterol and Triglycerides to HDL-C), which are the real indicators of cardiovascular health.

Blood pressure will decline to normal levels and your basal body temperature will typically fall to a level 1 – 2.5 degrees below the ‘normal’ of 98.6. It is of note that the normal temperature reading is an average established over many years which is an example of the inflammation levels of the average person. Excess inflammation in the body results in higher body temperature. After several weeks of restriction, you will find your morning basal body temperature drop. This is a good indicator that you have already reduced your core temperature and that restriction is having a positive effect.

It is essential to monitor everything that you eat. You cannot follow this lifestyle without knowing the calorie and nutritional content of every item you consume. The best tool to use for monitoring is the free CRON-O-METER (spaz.ca/cronometer/). Enter all foods (and it is important to weigh the foods at first) in this handy tool as you eat. It will provide you with the calorie content as well as the nutritional breakdown. Mix your food choices to get the proper mix of nutrients. You will quickly find that there is no room for any food types which provide little or no nutritional value.

Weight Loss Truths – Calorie Restriction is the Key to Weight Loss Success

Monday, September 20th, 2010 at 3:58 am

All successful weight loss programs rely on one common denominator; calorie restriction.

What is calorie restriction? is an effort to reduce the amount of calories one consumes in order for the body to achieve a negative energy balance. This is simply a person reducing food consumption to the point that they are burning more energy than they are consuming. The body is then forced to use stored fuel (muscle tissue, glycogen and body fat) in order to survive. The burning of these stored fuels is cause of the weight loss phenomenon.

How does a person achieve this negative energy balance through calorie restriction? First a person must have an idea on what a calorie is. A calorie is a measure of heat. Food is the fuel our body needs to generate heat. If the body is not getting enough fuel from food consumption then the fuel must be found elsewhere. That fuel is found in our body fat.

The best analogy for this process is gasoline and an automobile. Cars run on gasoline. Without gasoline, a car is useless. We drive our car and fill up with gasoline when we are getting low on fuel.

What would happen if we put 18 gallons on gas in our car if we only burned 16 gallons? We would have extra gas left over. That extra gas has to go somewhere so it goes into storage for when we only have 14 gallons available but we need 16 gallons.

What would happen if we never tapped into our gas reserves? The surplus would keep growing and growing causing a need for larger storage tanks.

The human body works in the exact same way. The surplus fuel (food) is turned into stored energy (body fat) and the only way to reduce how much fuel is stored in reserve is to limit new consumption of fuel (food). This is the only way that the human body can body fat. A caloric deficit must be established so stored energy (body fat) can be burned to keep us alive.

How is a calorie deficit achieved? The simplest answer is to eat a fewer number of calories then it takes to fuel your basal metabolic rate. The BMR (basal metabolic rate) is the measure of energy a person needs to subsist. People can figure out their BMR by using any of the numerous BMR calculators that can be found online.

Once the BMR is calculated a person can then have a goal to shot for. If the BMR is 2500 calories a day, they a person should shoot to try to eat fewer the 2500 calories a day for a consistent period of time.

How can a person effectively create a caloric deficit? Part 2 of this article will address this issue.

Oprah’s Calorie Restriction Diet – Why Oprah Recommends This Diet For Anti-Aging & Weight Loss

More and more research studies have concluded that a restricted in one’s diet slows the ageing process and its accompanying symptoms. In fact, it may lead to a long life and can be a hopeful health scheme. Oprah had even made this a topic on her show to share the advocacy on calorie restriction. means slow metabolism, which means slower aging.

Research on this subject started more than 60 years ago. Experimented on mice and rats, calorie restriction showed a slower ageing process. One hypothesis accounted for a decreased level of the thyroid hormone triiodothyronine (T3). A decreased level of this hormone slows down metabolism and the ageing of tissues.

A more recent study conducted by Rejuvenation Research in the second quarter of 2008 revealed that a calorie-restricted diet has an identical biological impression in humans, thereby making the proceed in a slow motion.

The next step of their research is to determine whether the slowed- ageing effect of calorie restriction can also slow down age-related tissue deterioration. Other health benefits of having restriction in calories in one’s diet include:

1. Reduction on risks of cancer

2. Reduction on risks of Type 2 Diabetes and may even decrease the need for medication

3. Reduction on risks of heart diseases

4. Alleviation on symptoms of Alzheimer’s disease

5. Weight loss

6. Elimination of low-level inflammation caused by oxidation damage

SIRT1, a protein that influences various functions such as metabolism and ageing, activates protein-like alpha-secretase that in turn suppresses beta-amyloid buildup.

Several diabetic patients who shifted from a low-fat diet to a low-carbohydrate diet for seven quarters manifested improvement in their hemoglobin A1C, the marker for blood sugar level in diabetes.

A warning has been given though to people who lose weight due to restricted calorie diet. Should they stop having restrictions on their diet, chances of gaining weight are inevitable.

Calorie Restriction For Anti Aging

Sunday, September 19th, 2010 at 2:42 pm

From an evolutionary point of view, skipping a meal here and there would be beneficial to the human body. After all the human body was designed to go for days without eating anything. In today’s society we have constant access to food and we are taking in calories all day long. is also known as the anti aging diet; it is based on the theory that by eating far less calories we will be able to slow down the .

A 2006 article in the Journal of American Medical Association suggested that by periodically restricting our caloric intake to as little as 890 calories a day, or fasting, resulted in a decrease in insulin levels and body temperatures, another two biomarkers of longevity. Restricting calories helps to eliminate the free radicals by burning off more calories than you take in thus reducing the amount of fat stored in the human body.

During a research study conducted in 1934, Clive McCay and Mary Crowell used calorie restriction diets to determine the effects on the . They noticed that when laboratory rats were fed all the needed nutrients but the calories in their diets were drastically cut, the rats lived up to twice as long as the rats that was not on this specialized diet. These results have proven consistent over all animals tested.

Tests on the higher primates are currently underway, but due to their long lifespan results do not yet exist. Certain tests are also being conducted on human volunteers and again, due to the long lifespan of our species, these test are sill underway.

The anti aging diet requires that the person restrict their diet on a large degree. Eating a diet that is full of fruits, vegetables, fish, and chicken is one way to start. Avoiding processed foods and certain fats has been shown to improve a persons’ overall health. A specialized diet is required for the . It’s not just cutting back on a meal here and there. This brings up the possible danger of not getting the necessary nutrients a person needs to live in a healthy manner.

Common Vitamins and over the counter products can help with aging such as Vitamin B, Vitamin C, Vitamin D, Vitamin E, and Antioxidants.

Up to one-third of older people can no longer absorb Vitamin B from their food. All of the different Vitamin Bs taken together as B-Complex work together as a team to perform vital biological processes, such as energy production and efficient metabolic function. Vitamin B boost energy levels and help fight fatigue.

Vitamin C is nature’s protective nutrient, essential for defending the body against pollution and infection and enhances the bodies’ immune system. Take 1,000 to 5,000 mg daily.

Vitamin D is manufactured in the skin following direct exposure to sunlight. Many studies show that Vitamin D production decreases in older people and in those who are housebound. Vitamin D is needed by the body to absorb calcium, which makes your bones stronger and helps prevent factures.

Vitamin E supplies Oxygen to the heart and the other muscles in the body. Accelerates wound healing and aids in the functioning of the immune system.

Substances called Antioxidants can neutralize free radical by pairing up or binding with the free radical elections thus inhibiting them from damaging cells in the human body. Natural Antioxidants are abundant in fruits and vegetables such as, apples, blueberries, broccoli, cherries, cranberries, Grapes, spinach, and Spirulina a blue-green algae.

Always consult your doctor before using this information.
