Why Exercise on Empty Stomach May be Better for Your Health

This is the first study to show that feeding prior to acute exercise affects post-exercise adipose tissue gene expression

If you have been wondering whether it is better to eat or fast before a workout, researchers now have an answer. A new study has found that exercise on empty stomach is better for your health in the long term.

The study analysed effects of eating versus fasting on gene expression in adipose (fat) tissue in response to exercise.

After eating, adipose tissue “is busy responding to the meal and a bout of exercise at this time will not stimulate the same (beneficial) changes in adipose tissue”, explained corresponding author of the study Dylan Thompson from University of Bath in Britain.

“This means that exercise in a fasted state might provoke more favourable changes in adipose tissue, and this could be beneficial for health in the long term,” Thompson added.

“We propose that feeding is likely to blunt long-term adipose tissue adaptation to regular exercise,” the researchers noted in the study published in the American Journal of Physiology — Endocrinology and Metabolism.

The study participants were a group of overweight males who walked for 60 minutes at 60 per cent maximum oxygen consumption on an empty stomach and, on another occasion, two hours after consuming a high-calorie carbohydrate-rich breakfast.

The research team took multiple blood samples after eating or fasting and after exercising.

The researchers also collected fat tissue samples immediately before and one hour after walking.

Gene expression in the adipose tissue differed significantly in the two trials.

The expression of two genes, PDK4 and HSL, increased when the men fasted and exercised and decreased when they ate before exercising.

The rise in PDK4 likely indicates that stored fat was used to fuel metabolism during exercise instead of carbohydrates from the recent meal.

HSL typically increases when adipose tissue uses stored energy to support increased activity, such as during exercise, Thompson said.

These results reinforce the view that “adipose tissue often faces competing challenges,” Thompson wrote.

“This is the first study to show that feeding prior to acute exercise affects post-exercise adipose tissue gene expression,” the study said. (Bollywood Country)

The Risk of FGM Hangs Above British Schoolgirls During Holiday Break

Ending FGM requires multiple entry points (and) enabling families and communities to be proactive in ending the practice of FGM is ultimately the most effective channel

As many families prepare to holiday abroad during the festive season, British charities on Monday warned that girls taken overseas could be at risk of female genital mutilation(FGM)

Known as FGM, female genital mutilation is a ritual that usually involves the partial or total removal of the external genitalia, including the clitoris. Some girls bleed to death or die from infections.

Cutting affects an estimated 200 million girls worldwide and is a rite of passage in many societies, often with the aim of promoting chastity, with the highest prevalence in Africa and parts of the Middle East.

An estimated 137,000 women and girls in England and Wales have undergone FGM. Many cases go unnoticed because they had happened at a young age and abroad, campaigners say. Campaigners say teachers should look out for warning signs, such as when a child is taken abroad for a long time to a country where there is a high prevalence of female genital mutilation.

“The best way of preventing the practice is by working with girls and their families … and training professionals like teachers and social workers to spot girls at risk of FGM,” said Leethen Bartholomew, head of Britain’s National FGM Center.

Some warning signs that a girl might have been cut include difficulty walking or sitting down, spending a long time in the toilet or becoming withdrawn, said the Center, run by children’s charity Barnardo’s and the Local Government Association.

FGM has been a criminal offense in Britain since 1985. Legislation in 2003 made it illegal for British citizens to carry out or procure female genital mutilation abroad, even in countries where it is legal.

In 2015, it became mandatory for health professionals, social workers and teachers in Britain to report known cases of FGM to police.

The practice mostly affects immigrant communities from various countries including Somalia, Sierra Leone, Eritrea, Sudan, Nigeria and Egypt.

British-based charity Forward, which supports FGM survivors from African communities, said though teachers have a crucial role to play, they should not stigmatize certain communities.

“While teachers need to be alert at all times about safeguarding children in their care, we also need to ensure that some communities are not unduly targeted and stigmatized,” said Naana Otoo-Oyortey, executive director of FORWARD.

“Ending FGM requires multiple entry points (and) enabling families and communities to be proactive in ending the practice of female genital mutilation is ultimately the most effective channel,” she said in emailed comments to the Thomson Reuters Foundation.
