Biofeedback can help you lose weight, if you use biofeedback for 10 minutes to reduce tension, every time before you eat a meal or eat a snack. Biofeedback is learned relaxation, and by relaxing before you eat, you are less likely to over-eat for emotional or stress-related triggers. There are many biofeedback relaxation machines and biofeedback relaxation Apps on the market. If you over-eat from stress, learned relaxation may help you eat less. Pick up a copy of Herbert Benson’s The Relaxation Response, and do it for a week, before every meal.
