The body utilizes fat as a fuel source in this nutrition system.  When excessive carbohydrates are consumed the body utilizes this as a fuel source through releasing insulin to transport the carbohydrates to the muscles to burn.  When your intake is mostly protein, fiber and fats then your body will begin to use more fats for energy.  There are four phases in this system, it begins with few carbohydrates to transition your body over and slowly adds them back as you progress.

Dr. Robert Atkins created the Atkins system.  If you would like more information, check out

Schwarzbein Principle

This is a five step road to optimum health and healing.  The first step is nutritional, including eating healthy foods, balancing meals,  drinking adequate amounts of water, and incorporating snacks into your day.  Step two deals with stress reduction and getting a sufficient amount of sleep.  In step three the individual identifies toxic chemicals like drugs and refined sugar and begins to avoid them.  A balanced exercise program for the individual begins in step four.  And, step five focuses on stabilizing hormones in the body.

This program was created by Dr. Schwarzbein.  Check out more information at


This is based on our ancestors that were hunter gatherers, before the advent of agriculture.  Their primary intake was protein which included high quality grass fed meat.  There were some vegetables, fruits and nuts as well as regional foods based on the climate.

In a nut shell, you would take in more protein, less carbohydrates, and some healthy fats.  The food would be fresh so you would have a lower sodium or salt intake which would help to balance out the body.

Paleo, as it’s been termed, was developed by Dr. Loren Cordain.  For more information check out

South Beach

The metabolism can be healed through this three step process.  The first step is to restrict the carbohydrate intake and help detoxify the body.  In step two, a variety of healthy foods are introduced and the body begins to balance itself.  The third step involves the act of maintaining health for life.

Sometimes you eat certain foods due to cravings, this nutritional system helps relieve those cravings and condition the body.

South Beach was developed by the cardiologist, Dr. Agatston.  For more information check out

Food Combining

The body uses different processes to break down different kinds of foods.  If the combination of food that the body ingests is too diverse, some of the nutrients will not be digested.

It’s beneficial to eat protein with vegetables solely.  Carbohydrates are best with fats and vegetables.  Fruit should be consumed by itself.  This is a general guideline, there are exceptions.


The Zone

People should adhere to a 40-30-30 ratio or 40% carbohydrates, 30% protein, and 30% fats.  Once in this zone, blood sugar levels can be maintained and cellular inflammation, which is the cause of disease, can be regulated.

The fats ingested should be good quality fats, some examples include fats that contain omega-6 and omega-3 fatty acids.

The Zone was developed by Dr. Barry Sears.  For more information check out

Metabolic Typing

The dominance in your metabolism can either be attributed to the sympathetic or parasympathetic part of  your autonomic nervous system or whether you oxidize or burn energy fast or slow.  Once aware of this dominance, food can be consumed that benefits the individuals specific metabolism.

Fast oxidizers and parasympathetic dominant people should eat a diet that is higher in protein.  Slow oxidizers and sympathetic dominant people should eat a diet that is higher in carbohydrates.

PH Balancing

The body consists of two substances: acids and alkaloids.  Each organ maintains a specific balance of acids and alkaloids for optimal health.  It’s when these substances are out of balance that the body is susceptible to illness and disease.

Many people tend to have more acidic tendencies within their bodies.  To help the body achieve a good PH balance it’s advantageous to drink water with a high PH balance or add Himalayan salt to water.  Other foods that are alkaline include; watermelon, honey, apple cider vinegar, and lemon.  Moderate exercise can also help the body.
