Possibility of Low-Carbohydrate High-Fat Diet in the Elderly

A study from the University of Alabama at Birmingham found that obese older people with a BMI over 30 had an ultra-low carb diet for eight weeks and improved body composition and metabolic health.

Older obese people are at particularly high risk of developing cardiometabolic disorders such as type 2 diabetes and cardiovascular disease. Not only total body fat mass, but also fat accumulation in specific sites such as the abdominal cavity and skeletal muscle contributes to an increased risk of developing these diseases.

Amy Goss and his colleagues found that an obese elderly person (34 men and women aged 60-75 years old, BMI30-40) consumed eight weeks of ultra-low-carb, high-fat foods without energy limitation and accumulated fat. We investigated the possibility of maintaining lean body mass while reducing the amount, and consequently contributing to the improvement of factors related to cardiometabolic disorders such as insulin sensitivity and blood lipids.

“After 8 weeks of intervention, the group that ate an ultra-low-carb diet had more weight and body fat loss than the control group, even though it recommended a weight-maintaining diet “Dr. Goth says.

Eggs played an important role in the ultra-low-carb diet. Dr. Goss’s team told the group to eat at least three eggs a day.

“Our intervention included eggs, but we cannot conclude that the outcome of this study was due to egg intake. However, the results show that whole eggs are a part of a healthy diet in the elderly. It seems that it can be taken as a part without adversely affecting blood cholesterol,” said Dr. Goss.

The differences in body fat changes between the two groups were mainly due to a decrease in abdominal fat and skeletal muscle fat.

“This study found an improvement in blood lipids that reduced the risk of cardiovascular disease. In addition, there was also an improvement in insulin sensitivity in the ultra-low-carbohydrate diet group that reduced the risk of type 2 diabetes.” The ultra-low-carb diet showed improvements in body composition, body fat distribution, and metabolic health.”

Effect of ultra-low carbohydrate diet on diabetes
An ultra-low-carb diet is an option for treating a variety of conditions, including type 2 diabetes, obesity, and nonalcoholic fatty liver disease, according to Goss.

“This study extends the implications of previous studies and shows that an ultra-low carb diet is a safe and potentially treatment option for older people in their 70s with obesity,” Dr. Goss. Says “This is the first study to show that older people reduce “metabolically harmful” body fat while maintaining skeletal muscle mass during weight loss with an ultra-low carbohydrate diet. ”

Although there is a lot of evidence about the effectiveness of ultra-low carb diets in the younger population, this study found that health was particularly high at risk of other diseases, while maintaining skeletal muscle to prevent age-related decline in function. One of the first studies to examine whether this diet could help improve obesity-related factors in older people aged 65 and older, a group in need of treatment to improve illness, adds Dr. Goss. .

Is the egg good or bad?
“Eggs have a history of being wetted in nutrition guidelines published by the American Heart Association in 1968,” says Dr. Goss. “The guidelines recommended that the weekly egg intake should not exceed 3 eggs.”

Dr. Goss said this concern was due to cholesterol and saturated fat in eggs. A new study subsequently found that dietary cholesterol had a negligible effect on blood cholesterol levels, and this recommendation was gradually relaxed. And finally this month, the Dietary Guidelines Advisory Committee published recommendations that recommend increasing egg intake throughout life, including the first meal of a pregnant, lactating, or infant.

“The Dietary Guidelines Advisory Committee has historically shown that eggs are an important source of protein, choline, vitamin B12, selenium, vitamin D, and many other essential nutrients, and are important for maintaining growth and muscle mass. It was recognized for the first time,” says Dr. Goth.
