Low-Carb Diet Is Healthy Even Without Fat Loss

Studies have shown that a low-carb, high-fat diet improves health. But it wasn’t clear if this is caused directly by the diet or caused instead by the fat loss that is a common result of the diet. In a new 3-year study, researchers controlled for fat loss and many of the same health benefits were still seen.

The researchers did this by providing prepared meals. They had to make sure that the subjects were getting enough calories so as to lose no weight. This meant increasing fat intake, sometimes by extraordinary amounts. Despite this including an increased in saturated fat, there was no increase of saturated fat in the bloodstream. This is yet more evidence against the scapegoating of saturated fat. The diets also would have been high in cholesterol and, unsurprisingly, all the health markers for cholesterol were positive.

On the other hand, there are confounding factors. Subjects were given prepared meals. This would naturally decrease the consumption of processed foods. To really understand what was going on, we would have to look at the precise ingredients.  For example, did these prepared meals have less industrial vegetable oils that are known to cause all kinds of health problems, including affecting metabolic syndrome?

The fact that there was greater amount of saturated fat in the diet indicates that the kind of fat one eats does matter. So, simply replacing sources of PUFAs with healthy fats, including saturated fats, will lead to massive improvements, whether it is caused by what is being eliminated or by what is being added in. Still, from what we know about the harm caused by excess starches and sugar, it’s hard to conclude that this study merely showed the positive effects of changes in the amounts and kinds of fats.

Whatever the cause, it is well-established at this point that a low-carb, high-fat diet is healthy. This is true, whether or not there is fat loss. Yet considering fat loss is a definitely health benefit typical of this diet, it demonstrates how the advantages are multiple. If you need to lose weight, it’s the best diet around. But if you don’t need to lose weight, it’s still great. There is no way for you not to come out ahead.
