Lopez has, in the past, cut sugar and carbs from her diet. In general, she eats foods that improve her performance, her skin, everything—like lean proteins and leafy greens. "She needs really good fuel for all the things that she's doing," her trainer Tracy Anderson told People a few years back. "It's all organic and it's all very well thought out, with the balance of very high-quality proteins and a lot of nutrient-dense food … Everything is fresh."

2. She Ditched Caffeine

"I haven’t had caffeine in years," she told People. “Health and nutrition experts agree that consuming more than 600 mg of caffeine a day (equivalent of four to seven cups of coffee) is too much,” says the Cleveland Clinic. “If you’re sensitive to caffeine, even moderate amounts can cause insomnia (trouble sleeping), rapid heart rate, anxiety and feelings of restlessness.”

3. She Works Out Hard

“Though her workouts constantly change to keep her body and mind engaged, a recent day saw the star doing five compound sets: supported lunges with dumbbells into weighted rope crunches; single dumbbell sumo squats into hanging leg raises; weighted leg presses into calf raises; seated leg extensions into weighted lying leg curls; and weighted hip thrusts into calf raises,” reports Us Weekly.

4. She Makes Health a Top Priority

Health “became the number one thing that we, in a way, took for granted for so long," Lopez told PEOPLE. "Not being able to see my mom and dad as much as we wanted, we didn't spend the holidays together — different things like that where you realize health is the number one most important thing in our lives, so it became a huge priority." As a result, she filmed a PSA promoting the WELL Health-Safety Rating, a label that companies can use to broadcast they take the health and safety of their employees seriously.

5. She Urges Caution During the Return to Work

"We have an excitement to get back to work safely and I've been adamant during my shoots that we follow protocols including testing and face masks and social distancing," she explained to People. "But as we continue to move forward, I want to have a comfort level and a peace of mind as we enter back into a more normal routine, which hopefully will be sooner rather than later." She sang at a pro-vaccine concert. “I want to contribute in every way that I can to help getting everybody back to work and back to a more normal state of life again," she says.
