I rolled my eyes when I heard that ChatGPT makes meal plans.
As a registered dietitian who carefully crafts meal plans based on a client’s needs, I thought there was no way artificial intelligence could do the same thing. But to be open-minded, I decided to give the ChatGPT meal plan feature a chance — on myself.
I had a baby seven months ago, and I’m diligently working on losing the last 15 pounds of baby weight. Anyone who has successfully lost weight knows that it’s not for the faint of heart. Weight loss takes dedication and consistency over weeks, months or years.

Doing so takes time, energy and dedication (as well as regular exercise and getting good sleep). So if AI can help with this process, I’m willing to try.

Developed by Open AI and launched in late 2022, ChatGPT is an artificial intelligence chatbot. Maybe you’ve asked ChatGPT to write something for you, like an essay, a blog post or even a heartfelt card without thinking about where the information comes from.
To find out how exactly it works, I spoke with Andrew Beam, Ph.D., assistant professor in the department of epidemiology at Harvard T.H. Chan School of Public Health who studies machine-learning models.
Beam explains that ChatGPT has digested all of the data on the internet and uses it to respond to prompts. “What it’s trained to do is predict the next word. It’s regurgitating words that it’s seen before,” he adds.
That may sound like a recipe (pun intended) for inaccurate information, but Beam says that’s not always the case. Some of his research shows that ChatGPT can predict enough to pass medical licensing exams. “In very controlled situations, it’s very accurate, but we also know that it just makes stuff up,” says Beam.
He provides a hypothetical anecdote: If he were to…
