Keto diet's rapid weight loss comes with hidden health dangers
The ketogenic, or keto, diet has stayed popular for years due to its links with weight loss and muscle growth. Many turn to it for quick results, but health experts warn of potential risks, especially for those with heart conditions. While some benefits exist, the long-term impact remains uncertain. The keto diet works by cutting carbohydrates drastically and replacing them with fats and proteins. This forces the liver to produce ketone bodies, an alternative fuel source made from fat. Foods like soda, sweets, and white bread are avoided—but so are healthier options like fruit, milk, and whole grains.
Short-term effects can include weight loss, lower blood sugar, and reduced triglycerides. However, side effects like nausea, fatigue, and constipation often appear. Dr. Tang notes that ketones can also form naturally through better sleep or intermittent fasting, without extreme dietary changes. For heart patients, the risks are more serious. The diet may raise LDL cholesterol, worsen liver health, and increase dehydration or kidney failure. It could even trigger diabetic coma in vulnerable individuals. Meanwhile, doctors still recommend balanced diets with complex carbs, lean proteins, and unsaturated fats for better heart health.
The keto diet delivers quick results for some, but its long-term safety is still unknown. Heart patients face higher risks, including organ strain and metabolic complications. For now, traditional dietary advice—with controlled portions and whole foods—remains the safer choice for most.
