The best advise I can give you is to consult your family doctor. Be sure to tell him or her that you are on high-fat, low-carbohydrate diet and not on a high-fat only diet.
It is well known that consuming foods that are high in fat can seriously impair our blood biochemistry. When this conclusion is automatically transferred to a low-carb dieting, it’s a misconception. Clinical data shows that the high-fat, high-carb diets —not high-fat, low-carb diets — made blood tests numbers worse.
A few cases in point:
* Researchers from Veterans Affairs Medical Center, University of Texas, concluded, “Compared with the low-carbohydrate diet, the high-carbohydrate diet caused a 27.5-percent increase in plasma triglycerides and a similar increase in LDL (”bad cholesterol”) levels; it also reduced levels of HDL (”good cholesterol”) by 11 percent..”
* In the article “Treatment of Obesity With Low-Carbohydrate Diets,” Drs.Rabast et al. wrote: “Concentrations of plasma triglycerides and cholesterol turned to normal during [low-carbohydrate] therapy. There were no side effects.”
* “Serum triglycerides decreased more after the high fat diet (52 mg/dl) than after high protein diet (67 mg/dl).” (Ibid.) * Out of my About.com weight-loss community members, 39 low-carb dieters mentioned cholesterol changes along with their weight loss. Two of them have had their numbers worsen and 37 had their numbers improve. Six reported that their blood pressure also decreased.
Atkins dieters also reported improvements in their cholesterol levels:
