Food Insecurity and Yo-Yo Diets May Raise Risk of Heart Disease Later in Life

One study presented at the American Physiological Society annual meeting set out to find the impact of weight-loss diets and involuntary reductions in food intake caused by food insecurities. This is the first of its kind to focus on long-term implications.


For the study, 16 rats were divided into two groups. One group received an average amount of food, while the other group experienced three cycles of a restricted diet. At the end of the study, an ultrasound was used to assess the rats’ cardiac and renal functioning, and blood tests were done to determine insulin sensitivity.

Study contributor Aline M. A. de Souza said, “We found that animals going through several cycles of weight loss and body weight recovery had reduced heart and kidney function at the end. They also had more insulin resistance, which can be a cause for diabetes. Even though the animals look to be healthy after ‘recovery’ from the diet, their heart and metabolism are not healthy.”

More research is needed to determine the biological mechanisms behind the findings and discover if the heart disease risk patterns found in rats are the same as in people. Researchers believe that changes in gene expression in response to caloric restrictions may change biological pathways that regulate blood pressure and insulin metabolism, a measure of how the body processes sugar.

Reduce Risk

It is vital that those who use yo-yo diets or who have food insecurities know about the risk of cardiovascular problems. Having the knowledge of a heightened risk could help many get testing done to catch a heart problem in the early stages.

Heart Rescue is an effective, doctor-formulated way to help support and promote cardiovascular health. This unique formula includes a variety of ingredients, including omega-3 fatty acids, CoQ10, magnesium, and hawthorn extract. These heart superstars can help reduce the risk of heart disease, strengthen the heart muscle, maintain healthy cholesterol levels, and support circulation.

Sarah began her interest in nutritional healing at an early age. After going through health problems and becoming frustrated with the conventional ways doctors wanted to treat her illness (which were not working), she took it upon herself to find alternative treatments. This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe. They enjoy their food, and take the time to relax and enjoy many of life’s little moments. These are life lessons she is glad to have brought back home with her.
