Since vinegar has been shown to further extend the time food stays in the stomach, taking it with meals could worsen gastroparesis .
Results from one human study indicate that apple cider vinegar has some pretty impressive effects on weight and body fat.
In this 12-week study, 144 obese Japanese adults consumed either 1 tablespoons (15 ml) of vinegar, 2 tablespoons (30 ml) of vinegar or a placebo drink every day.
They were told to restrict their alcohol intake, but otherwise continue their usual diet and activity throughout the study.
Those who consumed 1 tablespoon (15 ml) of vinegar per day had the following averages:
- Weight loss: 2.6 lbs (1.2 kg).
- Decrease in body fat percentage: 0.7%.
- Decrease in waist circumference: 0.5 in (1.4 cm).
- Decrease in triglycerides: 26%.
