John's smart goal is to lose around 8 pounds by starting to eat healthier foods. He plans to track his calorie and fat intake daily using a food journal. While grocery shopping with housemates, he looks for healthier options like low-fat and fat-free products. By the end of the semester, he hopes to have lost the desired weight through eating lighter meals throughout the day and switching to whole wheat products. So far, he has noticed a slight decrease in his waist size and plans to weigh himself at Thanksgiving to track his progress further.
