Kate Hudson invited many celebrity guests to the annual Halloween party she held at her Brentwood, California, residence.

Hudson works out three to four times a day. As she doesn’t have a lot of time, she believes in effective workouts. She insists on doing exercises that target the whole body, like aerobic fitness—this includes cardio exercises, strengthening exercises, weighted exercises, and muscle toning.

She also occasionally goes to a spin class for an intense 45- to 60-minute cardio workout, and on other days she’ll head to a dance studio to do two to three hours of advanced jazz-modern, which is a combination of cardio, strengthening, and toning.

In her book Pretty Happy: Healthy Ways to Love Your Body, Hudson says that she follows an alkaline diet. The alkaline diet includes foods like tofu, nuts, and most fruits and vegetables, and 60% to 80% of her calories come from such sources. She has also limited her meat consumption as it has a high acidic effect on the body.
