• Meghan Trainor revealed that her fiancé sparked her new interest in health and fitness.
• She said that he "saved" her, and taught her how to cook healthy meals.
• Cooking together could benefit your relationship by helping you communicate and indirectly increasing your libido.

Whether it's your family, friends, or partner, having someone to hold you accountable could help you reach your health and fitness goals — and singer Meghan Trainor knows this all too well.

In December, the 24-year-old said her fiancé Daryl Sabara "changed her life" by helping her learn to enjoy exercise. Now, Trainor says her beau has also taught her how to eat healthy — and enjoy it — too. 

"He saved my life in every single way, and he taught me how to eat healthy, and we work out together," Trainor told "Entertainment Tonight." 

Trainor used to struggle with exercise before meeting Sabara, especially after her two vocal cord surgeries. His support helped her make changes to her daily routine. Although the duo doesn't plan on tying the knot too soon, their health is at the forefront of their minds if they plan to eventually have kids, People reports. 

"That's why I’m working on my body," Trainor said. "I want to be as healthy as I possibly can be for one day when we want to have kids."

Eating healthy and exercising regularly are known to be good ideas for your health, but your relationship could benefit from both too. Cooking as a couple is especially great for forming a strong, long-lasting bond with your partner. According to researchers at Stony Brook University, couples who reported being "intensely in love" after a more than a decade of marriage found that physical affection and sharing novel experiences  — including cooking — were the keys to their success.

The Knot also reports that time spent cooking together can improve communication and serve as an intimate bonding experience. Not to mention, healthy eating could potentially boost your libido. It's important to note, however, that making weight loss into a competition could mess with your relationship by making you both feel threatened, Reader's Digest reports. 

For Trainor and Sabara it seems that having similar health priorities is working for them and they might just motivate you to start cooking healthy meals with your partner.
