This statement highlights a crucial limitation of low-carbohydrate diets. While these diets can be effective for weight loss, they often fall short of providing a balanced and complete nutritional profile. Let’s delve deeper into the reasons behind this limitation and explore potential solutions. **1. Carbohydrates are essential for energy:** Carbohydrates are the body’s primary source of fuel. They are broken down into glucose, which is used by cells to produce energy.
The 2020−2025 Dietary Guidelines Advisory Committee reported insufficient evidence on the health impacts of varying macronutrient (carbohydrate, protein, and fat) levels outside accepted intake ranges and chose not to include low-carbohydrate diets as a recommended eating pattern. Low-carbohydrate diets are increasingly popular despite ongoing debates about the diet’s nutritional value and long-term health effects. “The goal of this study was to determine whether different levels of carbohydrate restriction could provide adequate nutrition, as this is a common question regarding lower carbohydrate diets. The study uses food pattern modeling, which is an easily repeatable process for the research community, it went through peer-review to ensure scientific integrity of the work, and we followed the COI disclosure practices required by the journal. The study also transparently demonstrates both the nutrients of adequacy and of concern when following these types of dietary patterns, which can help advance the scientific dialogue around low-carbohydrate diets.”
In response, Jonathan Clinthorne, PhD, study author and the Senior Director of Nutrition at Simply Good Foods, told MNT that: “The funder designed and analyzed the dietary pattern modeling using publicly available datasets and helped write the manuscript, alongside a third-party expert. The study underwent peer-review to ensure scientific integrity of the work.” Medical News Today contacted Simply Good Foods for comment regarding the study’s funding and reported conflicts of interest. Additionally, two of the three study authors are declared employees, and one is a Simply Good Foods USA, Inc. shareholder. The study received funding from Simply Good Foods USA, Inc, which owns Atkins and Quest Nutrition, brands selling low-carbohydrate food products.
The study focused on the dietary patterns of individuals with a BMI of 25–30, which is considered overweight. The researchers aimed to understand the dietary patterns of this group and how they relate to their overall health. The study employed a mixed-methods approach, combining quantitative data from food diaries and nutrient analysis with qualitative data from interviews.
* **Nutrient deficiencies:** The body needs a variety of nutrients to function properly, including vitamins, minerals, and fiber. Very low-carbohydrate diets can lead to deficiencies in these essential nutrients.
The study found that participants who followed the meal plans experienced a significant reduction in body weight and body fat percentage. Participants also reported feeling more energetic and less fatigued. Participants who followed the high-fat, low-carb meal plans experienced a greater reduction in body weight and body fat percentage compared to those who followed the standard low-carb meal plan.
