What they did

The report interviewed nutritionists about meal plans suggested by chatbots. Marle Alvarenga argues that good technology starts a conversation rather than replacing the appointment.

How it went

The risks cited are dietary monotony, "miracle" ingredients and a worse relationship with food. The account gives no numbers.

Good to know

For professionals: use AI to vary recipes and shopping lists, and do the calculations and clinical adjustments yourself.

The prompt

I'm a nutritionist. Based on this plan I've already prescribed [summary], suggest [n] recipe variations with the same food groups and portions, using affordable ingredients from [region]. Do not change the quantities.

Replace what is in [brackets]. Prompt written by us from the account, not a literal copy of the source. Do not paste other people’s personal data (privacy laws such as LGPD and GDPR apply).

Summary in our own words. Results as stated in the original account; we have not tested or audited them. Read the source ↗ Found a mistake?
