Scoring your metabolic typing test
When you have finished the test, add up the number of A, B and C answers you have circled A____B____C____
If your number of C answers is 5 or more higher than your number of A or B answers, you are a fast oxidizer.
*If your number of A answers is 5 or more higher than your number of B or C answers, you are a slow oxidizer.
*If your number of B answers is 5 or more higher than your number of A or C answers, or if neither A, B, nor C’s are 5 or more higher than the other two, you are a balanced oxidizer.
If you are still not certain, you can try these two other drastic tests.
1. Niacin test: Take 50 milligrams of niacin on an empty stomach. If you experience an immediate flush, you are most likely a fast oxidizer. If you feel a moderate flushing effect, you are a balanced oxidizer. If you experience a significantly delayed flushing or nothing at all, you are a slow oxidizer.
2. Vitamin C test: Take 8 grams of vitamin C in equally divided doses over 8 hours. The fast oxidizer will respond by feeling acidic and uncomfortable, and may even experience other symptoms such as diarrhoea, nausea or increased intestinal gas. A true balanced oxidizer may find that his or her stomach feels less acidic. A slow oxidizer will have no response at all.
Fast oxidizers
You require foods with higher percentages of protein and fat than carbohydrates. Make sure there is protein in everything you eat including snacks. Your ideal macronutrient ratio is 20 percent carbs, 50 percent protein, 30 percent fat.
Proteins
All proteins are not created equal. The ones that are best for you are high-purine proteins, which are commonly found in fattier meats. This is not to say that you should cut out chicken or fish, but you need the heavier proteins most because they help slow down your rate of oxidation.
Choose from this list of proteins when deciding on a meal or snack:
High Purine: organ meats (pâté, liver, etc.), herring, mussels, sardines, anchovies
Moderate Purine: beef, bacon, dark meat chicken, duck, lamb, spareribs, dark meat turkey, veal, wild game, salmon, shellfish (lobster, shrimp, crab), oysters, scallops, octopus, squid, dark tuna
Low Purine: cottage cheese, milk, yogurt, eggs, cheese, white meat chicken, turkey, fish
Carbohydrates
Your metabolism thrives when your carb intake is limited, but there are different kinds of carbs. Some aren’t as bad as others. Avoid simple carbs, which convert to sugar quickly in the bloodstream. The carbs you can incorporate into your diet are the complex kind found mostly in nonstarchy vegetables. You can choose from these ideal carbs when deciding on a meal or snack.
Low-Starch vegetables: asparagus, cauliflower, celery, mushrooms, spinach
Fruits: avocado, olives, apples and pears (in limited quantity and never without protein on the side)
Grains: sprouted grain bread only (Ezekiel bread is a well-known brand that is available at supermarkets and health–food stores)
Legumes, tempeh, tofu
Fats
To best support your metabolism, you should be getting roughly 30 percent of your daily caloric intake from natural oils and fats. Choose these ideal fats when deciding on meal or snack preparation.
Nuts/Seeds (listed in order of protein content): waltnuts, pumpkin seeds, peanuts, sunflower seeds, sesame seeds, almonds, cashews, Brazil nuts, filberts, pecans, chestnuts, pistachios, coconut, macadamias
Fat/Oils: butter, cream, almond oil, peanut oil, coconut oil, sesame oil, flaxseed oil, sunflower oil, waltnut oil
Along with knowing the foods that are ideal for you, it is important to know the foods that are worst for you. You don’t always have to eat off the ideal foods list, but the following foods will sabotage your weight-loss efforts.
1. Don’t ever eat a meal that is predominantly carbohydrates.
2. Don’t drink alcohol. It causes an increase in blood sugar and fat storage, and it will lead to a sugar crash as well as an increased appetite for carbs. If you choose to have a drink, avoid sugary cocktails, beer, and wine. Stick to clear alcohols like vodka or rum with calorie-free mixers like diet or club soda, and you can always just do what I do and drink it all straight.
3. Don’t eat carbohydrates that are high on the glycemic load index. The next chapter will tell you everything you need to know about the GLI. For now all you need to know is to stay away from high-GLI foods. It is important for all metabolic types to watch their high-GLI intake, but it is especially crucial for you. If you should happen to eat high-GLI foods, make sure to combine them with a protein in order to slow down the production and release of blood sugar.
4. Don’t drink too much caffeine. It is true that caffeine can be used as a fat burner and a performance enhancer when exercising. This is only effective, however, when the caffeine is taken in pill form in conjunction with aspirin. In the forms of coffee, tea, and soda, caffeine gives you short-term energy but does so by getting your adrenal glands to dump adrenaline into your blood like it’s going out of style. As a result, when the caffeine leaves your system, your adrenal glands will be depleted for a while, which leaves you feeling weak and tired from substandard blood-adrenaline levels. Caffeine also speeds the rate of oxidation, which is the exact opposite of what you want your nutrients to do. Avoid caffeinated beverages whenever possible and keep your overall caffeine consumption to a minimum.
5. Don’t overcook your meat. Avoid overcooked animal products, since heat destroys essential amino acids and valuable enzymes.
You will have less physical ailments and feel energized if you eat the foods that contain the ideal macronutrient ratios for your metabolic type. However, these foods are all very high in calories. You must remember to keep within your caloric allowance in order to lose weight.
Slow Oxidizers
In order to best serve your metabolism and feel energized both physically and mentally, you require foods with a higher percentage of carbohydrates. Your ideal macronutrient ratio is 60 percent carbs, 25 percent protein, and 15 pertcent fat.
Proteins
The best proteins for slow oxidizers are low-purine proteins, which are found in leaner meats. It’s not that you can never have steak again, but high-purine, high-fat proteins slow down the rate at which you convert nutrients into energy, which is what you’re already doing too slowly, so the less the better. In general, you want to stick to this list.
Low Purine: white meat chicken, turkey breast, lean pork, catfish, cod, flounder, perch, sole, trout, white meat tuna, swordfish, low-fat cheese, low-fat cottage cheese, skim milk, low-fat yogurt, egg whites
Carbohydrates
Although your metabolic type is better than the others at processing carbs, you still have to pick and choose carefully. You want to avoid simple carbs, which convert into sugar very quickly in the bloodstream, and choose complex carbs instead. Follow this list of ideal carbohydrates when deciding on a meal or snack.
Vegetables—Low Starch: asparagus, cauliflower, celery, mushrooms, spinach, broccoli, brussels sprouts, cabbage, collard greens, cucumbers, garlic, kale, leafy greens, onions, peppers, scallions, sprouts, tomatoes, watercress
Vegetables—Moderate: Starch beets, eggplant, jicama, okra, yellow squash, zucchini
Fruits: apples, berries, cherries, citrus fruits, peaches, pears, apricots, plums, tropical fruits, olives
Grains: barley, brown rice, buckwheat, corn, couscous, kasha, millet, oat, quinoa, rye, spelt
Legumes tempeh, tofu (eat sparingly as they are high in purines) beans, peas (should be eaten fresh, never dried)
Fats
You should be on a low-fat diet to keep your metabolism working smoothly. This does not mean no fat — fat is still an essential part of any healthy diet. You should allow 15 percent of your caloric intake to come from fat. You can go over that percentage if you like, but eating foods that are too high in fat content can make you feel lethargic, anxious, and irritable. Choose from this list of fats when cooking a meal or having a snack.
Nuts/Seeds: raw and unsalted only—be very sparing
Fats/Oils: vegetable or nut oils such as almond, coconut, flaxseed, olive, peanut, sunflower, walnut
It’s not enough to know the foods that are ideal for you—you also have to learn which foods are worst for you. If you find yourself straying from the list of suggestions, remind yourself of these guidelines.
1. Don’t eat foods that are fatty or that contain high-purine proteins, such as organ meats and fish such as herring and sardines. Limit your intake of fats and oils, as they will slow down your ability to convert food into energy even further. Avoid red meat or dark white meats, and stay away from high-fat dairy, nut butters, and avocados.
2. Don’t drink alcohol. This is less of a concern for you than for fast oxidizers, but at the end of the day alcohol still increases your blood sugar and inhibits fat metabolism.
3. Don’t drink too much caffeine. This too is less of a concern for you than it is for fast oxidizers, but caffeine gives you energy by acting on your adrenal glands, causing them to over-produce and flood your system with adrenaline. When the caffeine’s effect has worn off, your adrenals are exhausted and you are left with lower-than-normal levels of adrenaline in your system, which makes you feel tired and sluggish.
4. Don’t exceed one serving per meal of simple or starchy carbs like potato, pasta, or rice, and always eat them with a lean protein to help stabilize your blood sugar.
Remember to consume your ideal foods in accordance with your caloric allowance; otherwise, you will not lose weight.
Balanced Oxidizers
If you are a balanced oxidizer, your diet is the easiest to follow, since you require an equal percentage of carbs, fats, and proteins. You feel at your best on a diet that incorporates a wide range of foods. Your ideal macronutrient ratio is 40 percent carbs, 30 percent protein, and 30 percent fat.
Proteins
You operate best when you are getting 30 percent of your total calories from protein. Be careful to mix the kinds of protein you eat so that you consume high-fat and high-purine proteins with low-fat and low-purine proteins. Choose from this list of proteins when deciding on a meal or snack.
High Purine: organ meats (pâté, liver, etc.), herring, mussels, sardines, anchovies
Moderate Purine: beef, bacon, dark meat chicken, duck, lamb, spareribs, dark meat turkey, veal, wild game, salmon, shellfish (lobster, shrimp, crab), oysters, scallops, octopus, squid, dark tuna, eggs, regular-fat cheeses
Low Purine: white meat chicken, turkey breast, lean pork, catfish, cod, flounder, perch, sole, trout, white tuna, swordfish, low-fat cheese, low-fat cottage cheese, skim milk, low-fat yogurt, egg whites
Carbohydrates
With regard to carbs, the real significant difference between balanced, fast, and slow oxidizers is not the types of carbs allowed but the quantity. You should get 40 percent of your nutrients from carbs, but like everyone you should avoid simple carbs and foods that are rated high on the glycemic load index, which we get into in the next chapter. Refined sugars like those found in cookies, sweets, and soda and processed grains like white bread or white rice should be shunned whenever possible, especially on a weight-loss regimen. You do best with a mix of fruits and vegetables from both the fast and slow oxidizers’ carb lists.
Vegetables—Low Starch: asparagus, cauliflower, celery, mushrooms, spinach, broccoli, brussels sprouts, cabbage, collard greens, cucumbers, garlic, kale, leafy greens, onions, peppers, scallions, sprouts, tomatoes, watercress
Vegetables—Moderate: starch beets, eggplant, jicama, okra, yellow squash, zucchini
Fruits: apples, berries, cherries, citrus fruits, peaches, pears, apricots, plums, tropical fruits
Grains: barley, brown rice, buckwheat, corn, couscous, kasha, millet, oat, quinoa, rice, rye, spelt
Legumes/Lentils: (all fresh, nothing dried), tempeh, tofu, beans, peas
Fats
In order to best support your metabolism, you need to be getting roughly 30 percent of your calories from natural oils and fats. Don’t eat excessive amounts of fat, but don’t specifically restrict your fat intake. You can choose from fats on both the fast and slow oxidizers’ lists of permissible fats.
Nuts/Seeds: (listed in order of protein content) walnuts, pumpkin seeds, peanuts, sunflower seeds, sesame seeds, almonds, cashews, Brazil nuts, filberts, pecans, chestnuts, pistachios, coconut, macadamias
Fats/Oils: butter, cream, almond oil, peanut oil, coconut oil, sesame oil, flaxseed oil, sunflower oil, walnut oil
Eat the foods that are ideal for you. Also remember these guidelines of what not to do.
1. Don’t eat meals made up of just one macronutrient. Make sure you adhere to your ideal ratio of 40 percent carbs, 30 percent protein, and 30 percent fat.
2. Don’t drink alcohol. It depletes glycogen storage in the liver, which causes an increase in blood sugar and fat storage. In addition, you will most likely experience a sugar crash, which leads to a heightened appetite for carbs and the nutrients you need to metabolize them. If you do have a drink, choose wisely and avoid sugary cocktails, beer, and wine. Opt instead for clear alcohols such as vodka or rum with calorie-free mixers, like club soda diet, light fruit juices or diet Snapple. And there’s always straight or on the rocks as well.
3. Don’t eat foods that are high on the glycemic load index. (Again, see the next chapter for a full understanding of glycemic load.) If you should happen to eat high-GLI foods, make sure you accompany them with protein in order to show down the rate of oxidation and stabilize blood sugar and energy levels.
4. Don’t drink too much caffeine. Caffeine is only effective as a fat burner or performance enhancer when taken in pill form and combined with aspirin. In the forms of coffee, tea, or soda, caffeine gives you short-term energy but does that by signaling to your adrenal glands to dump all of their store out into your blood. When the caffeine wears off, your adrenal glands are so depleted they have to take a break, which means that you feel tired and weak.
5. Don’t overcook your meat. Avoid overcooked animal products, since heat destroys essential amino acids and valuable enzymes.
