Cape Town, South Africa (Enmaeya News) — High-protein diets can cause nutritional deficiencies if carbohydrates are cut. Carnivore-style eating may lead to bad breath, constipation, and headaches. Diets high in red or processed meats can raise LDL cholesterol and increase heart disease risk. People with kidney problems may face further damage.

Experts recommend balanced protein from fish, beans, nuts, lean poultry, or soy, and advise consulting a doctor before major changes.

Weekend binge drinking can raise blood pressure even if weekday consumption is low, according to research in the African Journal of Biological Sciences. Heavy drinking strains the liver, weakens immunity, disrupts sleep, and may cause dependency. It can also slow muscle recovery, undermining fitness goals.

Extreme exercise can strain the heart, especially after endurance events like marathons. Studies show temporary heart injury after races, with long-term risks including scarring or thickened heart walls.

High-intensity workouts may trigger arrhythmias or sudden cardiac arrest in those with undetected heart conditions. The American Heart Association recommends 150 minutes of moderate activity weekly and medical screening for anyone at risk.
