How much oil should I consume if I'm trying to lose weight?

With oil, even olive oil, the hidden calories can add up fast, sabotaging your weight loss. Since all oil is 120 calories per tablespoon, it is a substance you want to use in minimal amounts. When you do choose to use oil on your salad or in your cooking, use only a teaspoon per person. It is part of the process of gradually reducing calories from low-nutrient foods and replacing them with calories that have a higher nutrient value.
