True or False: You can lose weight if you eat grapefruit or drink/use vinegar?

FALSE: This myth is considered ‘food folklore’--wishful thinking for many of us who have heard this faux promise for years. Unfortunately no food can "burn fat" nor "burn off the calories in a food". If you lose weight because you eat grapefruit, it's because you substitute this low calorie food for one in your diet that is likely much higher in calories and fat. Same for vinegar. It may get used in place of a much higher fat salad dressing for example.
