Saturated fat intake increases LDL cholesterol primarily by increasing larger, less atherogenic LDL particles, whereas high-carbohydrate diets increase smaller, dense, pro-atherogenic LDL particles.

Don't just look at your total LDL cholesterol number. If you eat high-carb, your LDL particles might be small and dense (higher risk). If you eat saturated fat, your LDL particles might be larger (lower risk). Particle size is a better marker of risk than total cholesterol.
