| Low carbohydrate | 72.7 | 1.3 | 73.0 | 1.3 | 73.2 | 1.4 | |
| Overall | 73.8 | 0.9 | 73.6 | 0.9 | 73.5 | 1.0 | |
| TC (mg/dL) | Low fat | 197.5 | 5.2 | 180.4 | 5.7 | 191.0 | 8.0 |

| HDL (mg/dL) | Low fat | 51.2 | 2.1 | 47.7 | 2.2 | 49.1 | 3.0 |

| LDL (mg/dL) | Low fat | 126.5 | 4.7 | 118.0 | 5.1 | 126.9 | 7.3 |
| Low carbohydrate | 119.4 | 4.9 | 110.9 | 5.3 | 123.2 | 7.1 | |
| Overalla | 123.0 | 3.4 | 114.5 | 3.7 | 125.1 | 5.1 | |
Overall estimates of means are averages across the two diets. Estimates for TC and LDL assume a quadratic trend in time. All other estimates assume a linear trend in time.
