D’souza doesn’t count calories—instead, she fasts from 11pm until 3pm the next day. “Can intermittent fasting improve your health? Losing weight and being physically active help lower your risk of obesity-related diseases, such as diabetes, sleep apnea and some types of cancer,” says Manpreet Mundi, MD. “For these diseases, intermittent fasting seems to be about as beneficial as any other type of diet that reduces overall calories.”

2. She Exercises On An Empty Stomach

D’souza prefers working out while she is still in a fasting state. “I like working out on an empty stomach,” D’Souza says. “That means morning for me - morning as in around 11.30am is my morning. I don't really have a meal as such, that I eat after a workout.” “There’s some research to support the idea that working out in a fasted state can burn more fat [than exercising in a fed state],” says Douglas Paddon-Jones, a muscle physiology researcher and a professor of aging and health at the University of Texas Medical Branch.

3. She Loves Cycling

Cycling is D’souza’s favorite form of exercise. “One of the major benefits of cycling is that it’s low-impact,” says Jaclyn Kubiak, PT, DPT. “It’s been shown that cycling reduces anxiety and depression,” says Dr. Kubiak. “Mainly, because you can make it fun. You get the added benefit of being outdoors or you can go do it with friends.”

4. She Snacks On Almonds

D’souza says almonds are her favorite “healthy munchies”. “Almonds are rich in nutrients that help protect the heart, including unsaturated fatty acids, phytosterols, magnesium, vitamin E, copper and manganese,” says registered nutritionist Nicola Shubrook. “Two research studies in 2012 and 2014 found that including almonds in your diet may reduce the risk of heart disease, specifically in overweight individuals. Further research has shown that almond consumption helps to reduce LDL cholesterol which may, in turn, help to reduce the risk of heart disease.”

5. She Loves Lemon Water

D’souza enjoys warm water with lemon while she’s fasting. “Like all produce, lemons contain phytonutrients, which protect your body against disease,” says Cleveland Clinic. “These phytonutrients have powerful antioxidant properties, which prevent cell damage from oxidation, the same mechanism that causes rust. Juice half a lemon into your water and you’ll add a mere 6 calories to your diet. Plus you’ll get more than a sixth of your daily vitamin C, which is needed to protect us from cell damage and repair injury.”
