Being a mutable fire sign, Sagittarians are all about trying new things and expanding their expertise. What better way to connect with your inner adventurer than exploring new foods? "Experiment with different healthy foods to increase your diet variety and make healthy eating fun and delicious so that this resolution becomes habit," Tamburello said. "Aim to try one new healthy food per week for diet diversity. Each week try a new lean protein, veggie, fruit, or whole grain. Try new healthy snacks, too!"
