Jennifer Aniston used to be told she needed to lose 30 pounds for her career. She developed a disciplined diet and exercise regimen focused on low glycemic carbohydrates, lean proteins, healthy fats, and low-fat dairy. Her routine includes yoga 4-5 times per week, 30-45 minutes on an elliptical or treadmill, and weight lifting. While her lifestyle may not be feasible for most, focusing on mindset over calories and developing a personalized plan can help achieve weight loss goals.
