Kennedy’s claims about the keto diet and mental health are part of a broader trend of people promoting fad diets as cures for serious health conditions, says Marci Evans, a registered dietitian and eating disorder specialist. “It’s predicated on this idea that our physical health and our mental health are simply a matter of the choices that we make around food,” she says.
Evans says that while diet can play a role in mental health, it’s just one piece of the puzzle. “We have to look at the entire context of people’s lives, their genetics, their lived experiences, their exposures to various forms of trauma,” she says.
“It’s a really complex picture, and it’s not going to be solved by any single diet,” Evans adds.
Palmer agrees. “I think it’s overly simplistic to say, ‘Oh, it’s all about what you eat,’” he says. “I think that’s dangerous.”
The bottom line is that while some preliminary research suggests that the ketogenic diet may have some benefit for certain psychiatric conditions, calling it a cure is premature and misleading. More rigorous scientific studies are needed to fully understand the potential benefits and risks of such dietary interventions.
In the meantime, individuals seeking to improve their mental health should consult with qualified healthcare professionals who can provide evidence-based recommendations tailored to their specific needs and circumstances.
As for Kennedy’s claim, the science simply isn’t there yet to support such bold statements. And until it is, it’s important to approach any dietary intervention with caution and skepticism, remembering that science is a process of careful investigation and verification, not a platform for sweeping declarations.
In the realm of mental health and nutrition, as in all areas of science, patience, critical thinking, and a commitment to rigorous research are essential.
