have a part in impacting the health advantages for dieting. Experts point out that this may play a role in identifying those having a higher chance of taking advantage of a restricted calorie diet.
The lowering of calorie intake as they maintain levels of vital nutrients is associated with the blocking of conditions like obesity, hypertension and type 2 diabetes, along with higher life expectancy.
A University of Edinburgh research team led the study that assessed the effects of a lower calorie diet on the health of both mice together with humans.
The 6-week study consisted of 96 mice whose calorie consumption every day was 30% lower than normal along with 85 mice who had a normal diet.
The team discovered that the lower calorie diet reduced blood sugar by 22% in young males but just 16% in young females.
The effects on body fat stood out even more according to researchers where males decreased fat mass by almost 70% but females had no reduction in fat at all.
Researchers observed that young female mice resisted fat loss as a result, of contrast to males, they restricted the breakdown of body fat, utilized lower energy and had elevated fat production in post meals.
In comparison, when dieting was initiated in older ages, there was an absence of significant variations in fat loss between the genders. Female mice saw a reduction in about half of their body fat, with a similar rate to males.
In a smaller human weight loss study conducted with the participation of 42 overweight or obese males and females verified the same age- and sex-based differences take place in humans as well.
Across 4 weeks, males below the age of 45 lost over 16% of their body fat, as females in the same age group lost just 8%, half as much as the males.
No differences were observed by researchers in fat loss between males and females over the age of 45, with both genders losing roughly 10% of their body fat.
Researchers also indicated that the human study was not initially formed to evaluate the influence of age and sex on dieting however the researchers had the ability to analyze the data from past occasions to address this. A wider human study looking into the impact of age and sex will be required to verify these findings, according to experts.
Professor Alexandra Johnstone of the Rowett Institute says “This is an interesting collaborative study, where the Rowett Institute team were able to contribute the human studies data, to explore this novel hypothesis. We also look forward to future research together, to follow up on this paper, to further support studies on woman’s health.”
