Dr. Michael Ruscio: Hi, this is Dr. Ruscio. And let’s examine this question. The short answer is that compared to an unhealthy diet, like a Standard America Diet that has a lot of processed foods and added sugars, any diet can be healthy and can be beneficial for weight loss.
However, if we were to compare different types of healthy diets, then we could find which one of the healthy diets is the best for weight loss. And this is what a recent study did. Again, they found that any diet can help toward weight loss. But a lower-carbohydrate diet is the best for weight loss.
And this is fairly definitive when we look at the type of study that this is. This is what’s known as a systematic review with meta-analysis. Essentially, it looks at other studies and aggregates and summarizes all the results. So in this particular study, there were 53 studies that were examined, looking at over 68,000 patients.
And when all this data was weighed, looking at high-carb diets, low-carb diets—or we could say high-carb, low-fat, which is one type of diet, versus low-carb, high-fat, another type of diet—when we look at these different types of diets or interventions, it has been shown that although all diets can work, the best diet for weight loss, the weight loss diet that works the best tends to be a lower-carbohydrate diet.
So if you’re struggling with weight loss, there can be multiple things that can contribute to weight loss, not just diet. But from a dietary perspective, the diet that seems to work the best for weight loss is a low-carb diet, although if you’re shifting from an unhealthy diet, any diet can work.
So this is Dr. Ruscio. And I hope this information helps you get healthy and get back to your life. Thanks!
