Certain widely adopted health practices, while seemingly beneficial, can actually be detrimental if taken too far, warns Dr. Mitch Ghen, chief medical officer at Access Medical Labs.

He identified five common "healthy" habits that may carry unintended negative consequences, emphasizing that moderation and individual needs are crucial for true well-being.

Eliminating Carbohydrates

While reducing carbohydrate intake can aid in weight management and blood sugar control, complete elimination is not advisable, Ghen explained. Carbohydrates are a primary source of energy and are found in nutrient-rich foods like fruits, vegetables, and whole grains. A diet that entirely omits carbs may lead to nutritional deficiencies. The Mediterranean diet, often cited as a benchmark for health and associated with reduced risk of dementia, diabetes, and cancer, does not restrict carbohydrates.

Over-supplementing

Taking a multitude of supplements daily does not automatically equate to better health. Ghen cautioned that supplements can interfere with each other's absorption. For instance, calcium, magnesium, zinc, and iron compete for the same absorption pathways. Moreover, combining certain supplements can amplify their effects to dangerous levels. For example, ginkgo biloba and omega-3 fatty acids can excessively thin the blood, especially for individuals already on blood-thinning medication. Ghen advises consulting a doctor to assess individual biochemistry, kidney, and liver function before starting any supplement regimen. He noted that up to 20% of drug-induced liver injuries are linked to supplements, and some compounds can accumulate to hazardous levels in the kidneys.

Excessive Exercise

While regular exercise is beneficial, chronic and excessive physical exertion can increase oxidative stress and inflammation, potentially negating some of its health advantages. Ghen noted that the glorification of endurance sports has not always been accompanied by an examination of their long-term effects on longevity. Signs of overtraining can include a decline in performance, a need for longer recovery periods, persistent fatigue, depression, or mood swings. Individuals may also experience an increased susceptibility to injuries and illnesses.

Consuming Only Egg Whites

Opting for egg whites exclusively to limit calories while maintaining protein intake overlooks the nutritional value of the yolk. Ghen stated that the yolk contains most of the egg's nutrients. While egg whites provide protein, an exclusive egg-white diet could lead to deficiencies in choline and fat-soluble vitamins A, D, E, and K, and may also hinder biotin absorption. Choline is vital for cell structure, brain functions such as memory and mood regulation, and muscle control. Insufficient choline levels can contribute to liver problems, muscle damage, and cognitive and mood disturbances.

Juice Detoxes

Ghen expressed disapproval of the term "detox," asserting that the body possesses its own natural detoxification systems. He recommends supporting these natural processes through proper nutrition, adequate sleep, physical activity, and maintaining healthy liver and kidney function, rather than relying on juice fasts. Hydration aids waste elimination through urine, while dietary fiber from fruits and vegetables promotes healthy digestion. Physical activity enhances circulation of the blood and lymphatic systems, and sleep is crucial for the brain's glymphatic system, which clears waste products during rest.
