Low‐carbohydrate (L‐C) diets are very popular, albeit controversial, for human weight loss. Diets rich in saturated fat (SF) are associated with increases in plasma triglycerides and cholesterol. Diets rich in polyunsaturated fat (PUFA) are associated with reductions in plasma triglycerides and cholesterol. In this study, healthy volunteers agreed to consume a SF‐rich red meat based L‐C diet (n=6) or a PUFA‐rich poultry/fish/shellfish (PFS) based L‐C diet (n=7) as part of a regimen for weight loss. Changes in dietary nutritional content, body weight, and plasma lipids were evaluated for this 28 day study. Both diets were associated with significant weight loss and a very low fiber intake. PUFA and cholesterol intake was significantly higher for consumers of PFS. No significant changes in plasma triglycerides or cholesterol were observed. Significant weight loss was associated with both L‐C diets, and a PFS diet could also be associated with higher PUFA intake, and a surprisingly high cholesterol intake. Standardization of cholesterol intake by PFS consumers may be beneficial for future studies of the L‐C diet.
