1. Keto Diet

Khanna adapted the keto diet before a filming project. “Yes I have taken to the Keto diet for an upcoming project and I must say that I have never felt better,” she says. “I have never felt more energetic and focused. However it's important to do it in the right way because it can all go wrong very easily. It's important to have a dietitian to guide you once you take it. I have been under great guidance and I have been preparing for something very important. So let's see how it fares. One day at a time and I wish to see some miraculous changes very soon."

2. Fresh Fruit

Khanna loves fresh fruit, especially cherries and mango which she calls her weakness. "Vitamin C is good for immunity," says Maya Vadiveloo, an assistant professor in the department of nutrition and food sciences at the University of Rhode Island. "It's an antioxidant so it can help with oxidative stress in the body. The primary benefit, in addition to being a really good source of vitamin C, is that (mangoes) are a decent source of vitamin A, folate and are pretty high in fiber, which is beneficial for colon cancer prevention, heart disease and weight control."

3. Tea First Thing

Khanna starts the day with a delicious cup of black tea. “Black tea packs a punch when it comes to heart health. Theaflavins help to lower blood cholesterol,” says UCLA Health. “And flavonoids — the same antioxidants found in red wine, dark chocolate and nuts —reduce the risk of heart disease by 8%. Studies show that with every cup of tea you drink daily, you can lower your blood pressure, the risk of major cardiovascular events (such as heart attack and stroke) and the threat of death from heart disease.”

4. She’s a Dancer

Khanna is a talented dancer. “When you begin moving, you immediately release the brain chemicals dopamine, adrenaline, and endorphins, causing a powerful and lasting effect I call ‘energized optimism,’” says Kelly McGonigal, PhD, a leading health psychologist who studies the mind-body connection, and author of The Joy of Movement.

5. She’s a Coffee Person

Khanna calls herself a “coffee person”. “There aren’t a lot of downsides to drinking moderate amounts of coffee — and in fact, it can have positive effects on your health,” says Devon Peart, MHSc, BASc, RD. “Coffee contains about a thousand different botanical compounds.”
