Very Low-Energy Diet Safe, Acceptable for Adolescents

Alternative to Weight Loss Drugs?

While weight loss drugs are transforming the obesity treatment and semaglutide is now approved for adolescents as young as age 12 years, “access to these medications is limited, and not all families want to commence on medication for their child›s obesity,” Dr. Gow said.

As an alternative, a very low-energy diet, with the interaction of a dietitian, can enable adolescents “to develop a healthier relationship with food, including encouraging the consumption of more fruits and vegetables in their diet, not only to assist in weight loss but for good health,” she said.
 

Very Low-Calorie Diet Concerns for Adolescents Addressed

Early studies suggested concerns of health effects from very low-calorie diets in adolescents, including potential cardiac effects; however, subsequent studies, including a systematic review published by Dr. Gow and her team, have shown that such results were likely the result of nutritional deficiencies in the diets, which can be overcome with careful food selection and dietary counseling.

Another key concern has been a potential effect on growth, but Dr. Gow noted that “in our short-term study we saw small increase in height (0.1 cm), and other more recent studies suggest that a short-term very low-energy diet does not impact growth.”

And in an earlier pilot study, the authors also found an association between the very low-calorie diet and an improvement in the quality of life for youth with type 2 diabetes.

A key caveat with the findings is that participants in the study all received supervision and monitoring from a trained dietitian, and Gow noted that that element is essential.

“We therefore do not recommend adolescents in the community undertake this type of diet without appropriate support,” she said.

“Close monitoring of adolescents by a health professional following a very low-energy diet is essential to ensure that the very low-energy diet is leading to holistic health benefits for the individual.”

Following the 4-week regimen, participants were randomized to transition to interventions of either continuous energy restriction or intermittent energy restriction over the 52 weeks, and further findings from the study will be presented at the obesity meeting in May.

The authors had no disclosures to report.
