My mom (60) was eating 6-700 cal a day! trying to diet..now she's eating verywell at 1300 cal still loosing 1lb a week.. can she loose faster somehow?

Often times - faster: isn't better. Eat healthfully. Try to eat at least 5 servings of vegetables & 4 of fruit per day. Increase nutritional fiber. Avoid refined sugar & junk carbohydrates. Avoid alcohol, sweetened juices, soda & caffeinated beverages. Aim for 7.5 to 8 hrs of sleep / night. Hydrate w at least 64 oz of water / day. Calories burned must > calories consumed. Do both cardio & weight training.
