A balanced diet is crucial for weight loss and overall well-being. Numerous studies emphasize the significance of dietary choices in managing weight and reducing the risk of cardiovascular diseases.
Low-Carbohydrate vs. Low-Fat Diets
A low-carbohydrate diet can reduce obesity and may improve dyslipidaemia compared with a low-fat diet.
Mediterranean Diet
The Mediterranean diet has been linked to numerous health benefits, including a lower risk of diabetes and improved metabolic syndrome status. A study published in the Canadian Medical Association Journal highlighted the positive effects of Mediterranean diets on metabolic syndrome. Research also indicates that a Mediterranean diet can reduce blood pressure and immune cell response after immune stimulation.
Protein Sources
Healthier protein sources, such as fish, poultry, and low-fat dairy, may reduce the risk of coronary heart disease when substituted for red meat. Lean seafood intake has been shown to reduce cardiovascular lipid risk factors in healthy subjects.
