1. She Drinks Lemon Water

The A-lister has lemon water on a regular basis. Jana Beaudoin, NBC-HWC Certified Health & Nutrition Coach Anti-Aging & Longevity Center of Philadelphia says, "Lemon water is low in calories. Drinking it instead of higher calorie beverages could contribute to weight loss. Consuming lemon water may also help boost metabolism. Good hydration enhances the function of mitochondria that helps generate energy for the body. In fact, drinking water induces thermogenesis, a process in which calories are burned to produce heat. Lemon water may also serve as a morning laxative and improve digestion, which may help prevent the buildup of toxins and inflammation. Lemons are a good source of vitamin C, supportive for boosting immunity, cardiovascular health, and skin health."

2. She Loves Pilates

The 42-year-old is known for being active and told Cosmopolitan UK, "My preference is pilates always. I love pilates, it makes me feel great." Beaudoin explains, "Pilates is an effective low-impact workout which can help you tone muscles, build core strength and improve posture. Increased strength may boost metabolism. Incorporating Pilates with other forms of cardio and strength training in addition to eating a healthy diet may help you achieve your weight loss goals. Cardiovascular exercise should equate to 150 minutes a week in addition to 2 strength training sessions. Participating in Pilates 2-3 times a week in addition to a few sessions of cardio should support optimal fitness."

3. Intermittent Fasting

Beaudoin says, "IF is an eating pattern that involves regular, short-term fasts. If may reduce risk factors for health conditions such as diabetes and cardiovascular disease. It may also help lower cholesterol and blood sugar levels. It can help you lose weight, with time restricted eating, they're generally less calories consumed. Thus it is still important to consider the quality and quantity of calories consumed. Short term fasting may also increase fat burning."

4. Eats in Moderation

Hudson told People she doesn't deprive herself of anything and Beaudoin explains, "Eating everything in moderation can work for some, but not all. It really depends on your definition of moderation. It works because there is no deprivation. It is difficult to cut out groups of food for extended periods of time. Diets fail because they are not sustainable. Eating everything in moderation lightens up the rules, removing the feeling of restriction that can come from cutting out bread, pizza or dessert. However, for eating in moderation to work, you likely need your own rules. Such as eating a healthy diet rich in vegetables, fruits, lean protein, whole grains and healthy fats 80-90% of the time. This gives you some leeway to add in other foods you enjoy but that may have a higher caloric/sugar/fat intake. You make room for them in your week, but on a less frequent basis. Creating your own moderation type guidelines- Friday night pizza, dessert on Sunday, eating mindfully and slowly, ensuring 5-7 vegetables a day etc. This type of moderation encourages healthy eating habits."

5. She Has Support

The actress uses WW to help track what she eats and told People, "I have never been an extremist. I love food. And I love a good cocktail," she says. "For me, it's really about everything in moderation; I stay mindful of what I put in my body and remember that it's OK to enjoy yourself; WW emphasizes that living a healthy life doesn't mean feeling deprived." Beaudoin states apps like WW are, "Great for accountability and awareness. Supports mindful eating and a focus on nutrition for overall health." Dr. Jinan Banna, PhD, RD., a registered dietitian and professor of nutrition adds, "A program like WW is one tool to help you stay in shape. WW uses a points system that helps you to keep track of what you are eating. Rather than having to count calories, you can use an app to stay within your 'points' budget and receive a personalized food plan."
