I just wonder how anybody can figure out if the low carb diet works well for him or just masks the symptoms. Well being is probably a good indicator. But what else, any specific tests ? BTW I just remember 1-2 years ago I tried for a while eat only saturated fats (no fish oils, flax, etc). When I had my cholesterol checked it was high (250) but the LDL/HDL ratio and triglycerides were perfect. When I eat mixed fats my cholesterol gets below 200 but the ratios are worse. So the question which situation is better ?
