Past studies have demonstrated that mice that were withdrawn from a high fat diet, similar to what many people do when dieting and restricting calories, have been shown to cause stress levels to increase.
A recent study showed that dieting mice had higher levels of the stress hormone corticosterone and showed symptoms of depression in stressful situations. In addition, the mice had altered DNA after dieting, with changes in the genes that control appetite and stress remaining even after they were fed back to their pre-diet weights. Previously restricted mice showed unusually high levels of hormones that regulate appetite when given access to a high fat diet, leading to stress-induced binge eating.
Take home message: Make sure to include a healthy source of dietary fat with each of your meals and snacks during the day. Healthy sources include: olive oil, peanut oil, canola oil, avocados, unsalted nuts and seeds, vegetable oils (safflower, corn, sunflower, soy, and cottonseed oils), fatty cold-water fish (salmon, mackerel, and herring), flaxseeds, flax oil, walnuts, and high-quality omega-3 supplements.
