I’m on a mission to show you that keto friendly recipes don’t have to be difficult, time consuming, or taste like "diet food". Studies show that TG/HDL ratios correlate with cardiovascular risk and cardiovascular mortality. This is because observational studies show a small cardiac benefit, but randomized, controlled trials (RCTs) show they can reduce LDL but may increase both cardiovascular events and risk of dying.8 Furthermore, mechanistic data suggest seed oils can increase oxidation and inflammation, although clinical trials haven’t shown this.9 See more in our evidence-based guide to vegetable oils. Although there isn’t universal agreement on ideal levels, studies suggest greater than 4 is high-risk, and clinical consensus is that less than 2 is a reasonable target, with lower being better (assuming HDL is above 40mg/dL (1.0 mmol/L)).20 Studies also show the ratio is correlated with insulin resistance in adults and children.21 You can follow your trend to make sure the ratio is not increasing, since in most circumstances lower is better. Therefore, it is unknown if the conclusions from studies of people following a low-fat diet or standard Western diet are applicable to those on a low-carb diet.
