Restrictive Diet


A restrictive diet often involves eliminating or significantly reducing certain food groups or quantities. Here's what experts say:

  1. Kelsey Pontius, RD, cautions against overly restrictive behaviors, highlighting how they may lead to nutritional deficiencies. Instead, she suggests incremental changes in diet and understanding the reasons behind restrictive eating behaviors to build a healthier approach to food 1.

  2. Peter Attia, M.D., distinguishes between different forms of dietary restrictions, noting that while restrictive diets like keto and carnivore can lead to weight loss, they aren't necessarily healthy if they don't provide essential nutrients. He emphasizes the importance of balancing dietary restrictions with nutritional needs to avoid health issues like nutrient deficiencies 2 3.
