Ask the Nutritionist

Ask the

Q: Why do I eat so much when I am tired?

A: A hormone in your gut called ghrelin is responsible. It actually causes us to eat more because food appears more desirable. In a brain imaging study subjects receiving an infusion of the hormone responded more strongly to pictures of food. Ghrelin increases when we are sleep deprived making food more appealing.

Q: Are there specific foods that can lower my cholesterol?

A: Yes. Some foods do help lower cholesterol and blood pressure. Pistachios and other nuts are rich in monounsaturated fat, fiber and phytosterols. They are also full of potassium. These nutrients help lower cholesterol and blood pressure. Omega 3’s are also protective. Salmon is the best source of omega 3 fatty acids so eat Wild Alaskan Salmon. Consumer groups are currently encouraging us to buy it despite the higher price in order to protect the supply. If you don’t like fish, supplement your diet with capsules of fish oil to lower blood pressure and protect the heart.

Q: I don’t eat that much and I can’t lose weight?

A: We often lose perspective about how much we eat and exercise. You may eat more than you think. Increase your current exercise program to boost your metabolism but also journal to determine your actual intake.
