dietary changes are not resulting in weight loss. He shares with you that he has stocked
his fridge and pantry with only low-fat and fat-free foods. Explain to him why these types

(or salt) can be used to improve the taste. Additionally, the lack of fat or simply the knowledge

end result is often the consumption of more calories than if you had just ingested the regular
product initially.
