CONSEQUENCES OF LOW CARBOHYDRATE
HIGH PROTEIN DIETS

By Karen M. Gauci-Manno M.P.H., R.D., L.D.
Dietitian/Nutritionist

   Stop before you put diesel fuel into an unleaded tank. Most of us wouldn’t put diesel fuel in an unleaded tank, but we are putting our bodies through a lot of unwanted health risks. Maybe we don’t know all of the health risks involved when we go on a low-carbohydrate, high-protein diet, but we know our cars aren’t going to drive well with improper fuel. So why take the risks if you don’t have to? Along with these health risks, we all know how hard it is to eat most meals without the best part, carbohydrates. Don’t take the best part out; enjoy your carbs and avoid the risks. Below are reasons why we shouldn’t go on high-protein, low-carbohydrate diets.Clipboard

Risk #1 GOUT

Gout is caused by excessive uric acid in the blood that deposits urates of sodium in and around the joints which cause inflammation (gouty arthritis). The inflamed joints that are affected may be any joints but gout usually begins in the knees or feet. A diet high in purines (protein foods) are broken down to uric acid in the body. Examples of foods high in purines are; meat, poultry, seafood, eggs, and liver.

Risk #2 KIDNEY STONES

High-protein diets will draw calcium from the bones and form calcium oxalate stones. Along with calcium oxalate stones you can also form uric acid oxalate stones due to high-protein diets. Most of these stones are formed in the kidneys, as kidney stones.

Risk #3 OSTEOPOROSIS

As explained above, if there is calcium loss over time you can eventually develop osteoporosis from excessive protein intake.

Risk # 4 FATIGUE

The body’s main source of energy is from carbohydrates. If the body doesn’t have the carbohydrates available, then the body uses protein for energy. This is called ketosis. Ketosis results from the incomplete metabolism of fatty acids, generally from carbohydrate deficiency, and is commonly observed in high fat protein diets. Eventually you are eliminating your body’s main fuel line and replacing it with an alternate fuel line. For example, would you expect to win a basketball game if you were to play the game with your 2nd string instead of your 1st string? In all probability not, so don’t settle for fatigue.

Risk #5 DEHYDRATION

Most high-protein diets stress to drink more fluids due to the increased fluid loss. Most Americans don’t get the fluid intake that is recommended, or they consume mostly caffeinated beverages as their main source of fluid intake. Caffeine is a diuretic and will promote dehydration, along with high-protein diets. When the body is slightly dehydrated you feel tired (fatigue) and or “just not right”. Avoid high-protein diets and add more water each day and you should feel much better. If you are active and work out you should drink two cups two hours prior to your workout and five to ten ounces every 15 to 20 minutes during your activity to prevent dehydration on a regular balanced diet.

Risk #6 BAD BREATH

When you consume a high-protein, low-carbohydrate diet and the body goes into ketosis, your breath will give you away. Most breath mints won’t cover the bad breath and don’t forget, you can’t have a breath mint due to the carbs. So don’t go around smelling like a cross between nail polish and over ripe pineapple.

Risk # 7 POOR ATHLETIC PERFORMANCE

Athletic performance will be hindered without adequate consumption of complex carbohydrates. When your body is neglected with energy (low-carbohydrate/high-protein diet), your performance will be insufficient. Prior to any athletic competition, most athletes’ carbohydrate load for strength, endurance, and speed. Also remember, as discussed earlier, dehydration will promote fatigue which in part will lead to poor athletic performance. Rule of thumb: drink at least two cups two hours before your workout and five to ten ounces every 15 to 20 minutes during your activity.

Risk #8 CANCER

The National Cancer Institute and the American Cancer Society recommend, based on scientific research, a diet high in fiber and low in fat to lower cancer rates. Risk of many cancers is likely to increase when most of your complex carbohydrates (plant-based diet) are eliminated from the diet (i.e. fruits, vegetables, beans, lentils, and whole grains).

Risk #9 HEART DISEASE

Studies have shown that a diet high in animal protein, cholesterol, and saturated fat and low in fiber and carbohydrates have been linked with heart disease. Animal protein, cholesterol and saturated fat will raise serum cholesterol, especially LDL (low-density lipoproteins) or bad cholesterol. A plant-based diet has helped lower the bad cholesterol (LDL). In addition, a diet high in meat will increase homocysteine levels and iron stores in the body, as evidence has shown may increase the risk of heart disease.

Risk #10 HYPERTENSION

Key minerals such as potassium, magnesium and calcium work together with sodium as intercellular and extracellular fluids. A diet high in these three minerals have been shown to lower blood pressure. A diet high in complex carbohydrates and fiber contain potassium, magnesium, and calcium, which include fruits, vegetables, whole grains, and nonfat dairy products. Blood pressure will likely increase with age on a typical high-protein, low-carbohydrate diet.

Risk #11 LONG TERM WEIGHT CONTROL

We all want to lose weight, but keeping it off for the long run is difficult. Low-carbohydrate, high-protein diets are limited in the amount of foods that we can consume at one time. Next, we start to feel deprived and bored and then we are more likely to have cravings and or binge later on foods that are high in sugar and fat. Variety is the spice of life; have a little of everything, and keep the weight off for life and don’t short-change yourself. The best bet for permanent weight loss and control, as well as good health, is to increase the amount of fruits, vegetables, whole grains, beans, and non-fat dairy products along with eliminating high caloric dense foods such as cookies, fries, desserts, candy, chips, etc. Research has shown, the majority of people who succeed in long-term weight loss have consumed a low-fat, high-fiber diet along with regular exercise.
