Ione Firth’s Clean Eating Tips from Registered Dietitians

As a health journalist, Ione Firth has interviewed dozens of registered dietitians over the years. But it wasn’t until she faced her own health plateau—low energy, weight gain, and stress—that she truly absorbed their advice. “I had all the information,” she says. “But I wasn’t living it.”

So she went back to her notebooks, reread interviews, and began following the very wisdom she’d once published for others. “Every dietitian I spoke with emphasized simplicity, not perfection,” she recalls. “That surprised me.”

Instead of crash diets, they talked about real food. Instead of restriction, they focused on balance. Ione started small: one home-cooked meal a day, more water, fewer ultra-processed snacks. She swapped morning pastries for whole-grain toast and eggs. At lunch, she chose colorful salads with protein. Dinners became an opportunity to try new vegetables and flavors.

She also learned to listen to her body. “One dietitian told me, ‘Hunger isn’t the enemy. It’s information.’ That changed everything for me,” Ione says. She stopped labeling food as good or bad and focused on how it made her feel.

As weeks passed, her energy returned. Her mood lifted. And food stopped being a source of stress—it became a way to care for herself. “The experts weren’t preaching restriction,” she smiles. “They were teaching nourishment.”
