This study compared two popular diet approaches for weight loss: a very-low-carbohydrate, high-fat diet (similar to keto) versus a high-carbohydrate, low-fat diet. Researchers followed 88 adults with abdominal obesity for 24 weeks, ensuring both groups ate the same number of calories - just with different ratios of carbs and fats.
The good news is that both diets were equally effective for weight loss, with participants losing about 11-22 pounds on average. Both approaches also similarly improved blood pressure, inflammation markers, blood sugar, and insulin levels - all important factors for metabolic health and longevity.
However, the diets affected cholesterol differently. The low-carb diet was better at lowering triglycerides (blood fats) and raising HDL ("good") cholesterol. But the high-carb diet was more effective at lowering LDL ("bad") cholesterol. Notably, about 1 in 4 people on the low-carb diet actually saw their LDL cholesterol increase significantly, which could be concerning for heart health.
This research suggests that while both dietary approaches can support weight loss and metabolic improvements, individual responses vary - especially for cholesterol. In clinical practice, this reinforces the importance of regular lipid monitoring when following any weight loss diet, particularly low-carb approaches, to ensure the metabolic changes are beneficial for your long-term cardiovascular health.
