Low-carbohydrate diets were associated with a significantly higher risk of all-cause mortality.
These findings support the hypothesis that the short-term benefits of low-carbohydrate diets for weight loss are potentially irrelevant.
Given the facts that low-carbohydrate diets are likely unsafe and that calorie restriction has been demonstrated to be effective in weight loss regardless of nutritional composition,  it would be prudent not to recommend low-carbohydrate diets for the time being. Further detailed studies to evaluate the effect of protein source are urgently needed.
Interestingly, this was a similar mortality risk to the onestudy in my last post, 31% increased risk here, 33% in Harvard’s analysis of the large Nurses’ Health Study and Health Professional Follow‐Up Study cohorts:
The risk of all-cause mortality among those with high low-carbohydrate score was significantly elevated: the pooled RR (95% CI) was 1.31 (1.07–1.59).
There’s something about eating a lot of animal food that just isn’t good. I’ve said for years now that how we raise animals for food is contributing to chronic disease in humans. It’s more than saturated fat and cholesterol, although they play a part. Animals are higher up on our food chain. Being so, they bioaccumulate POPs (Persistent Organic Pollutants) which have been linked to a range of metabolic disorders. Since POPs are often hydrophobic or lipid soluble, there are higher levels in an animal’s body fat, including our own.
If you’re eating a high-fat diet and that fat is coming from cheese, eggs, bacon, butter, and other animal sources, you’re being exposed to more environmental pollutants than if you are eating either a low-fat diet or a plant-based diet.
