What is it?
Metabolic Typing is a way to create an individual nutritional plan based on a person’s genetic makeup and their rate of metabolism. By answering a questionnaire on how one feels after eating certain foods, and gathering information about a client’s ancestry, a nutritionist can determine which metabolic type their client is, and better develop a nutrition plan for that client.
The Fast Oxidizer
The best form of exercise for a fast oxidizer who is at a healthy or low body weight would be high intensity and short duration activities. If overweight, including more aerobic activities would be of benefit until a healthy weight is reached.
Fast oxidizers need to eat a full breakfast and they need to eat frequently.
Fast oxidizers have a higher rate of metabolism then people from the other categories. This means that their bodies can convert the food they consume into energy at a faster rate then a slow or mixed oxidizer.
People who are fast oxidizers tend have stronger appetites, and they feel their best when consuming a diet high in protein and healthy fats. Vegetables are the best source of carbohydrates, and starches and refined grains can be eaten in moderation. Fast oxidizers can be hyper, impatient, and competitive, and they often suffer from hypoglycemia. (low blood sugar) Generally they have overactive adrenal and thyroid glands. By consuming more proteins and fats, a fast oxidizer will feel better, have balanced blood glucose levels, and have more energy.
The Slow Oxidizer
The best form of exercise for people in this group tends to be longer in duration and lower in intensity.
Slow oxidizers need to eat a light breakfast that contains some protein and need to eat three meals a day. Skipping meals is not recommended.
Slow oxidizers have a slower metabolism because their bodies take longer to convert the food they eat into the energy their bodies need. Generally, they feel and perform at their best when consuming higher amounts of vegetables and lower levels of proteins and fats. Slow oxidizers generally do not do well on the keto diet as the excess protien and fat bogs them down. Studies show that 80% of adults tested fall into this category along with many vegetarians.
Slow oxidizers generally have smaller appetites and low, steady energy levels. They will often feel depressed and lethargic and tend to have higher blood sugar levels. They can suffer from hypothyroidism. If slow oxidizers begin craving sweets, it is usually because they have been eating a higher amount of starchy carbohydrates.
As with their food, variety with exercise is important for this group. Changing up their routine keeps them feeling their best. They can perform both high and low intensity exercise.
Mixed oxidizers can eat almost anything if they maintain a good nutrient balance. They tend to have less issues with maintaining a healthy body weight and they don’t have many cravings. When people of this metabolic type eat a diet that sways to far to either the fast or slow metabolic types, they will feel sluggish and generally “not well.” Eating a large variety of foods is important to maintaining balance for mixed oxidizers.
Becoming more mindful of how the foods you eat affect you and finding a balance that works for your body is important and will vary in each individual. There can be shifts in your nutritional balance due to emotional or physical stress leading to fatigue, digestive and emotional issues. Paying close attention to your body during these times and ensuring you are eating the best foods for your metabolic type is extremely important in staying healthy.
