London, Dec 28, 2017: In a bid to cut down obesity, men and women living in Britain are being urged to reduce their intake of calories to just 1,600 a day, according to new health guidelines.

The suggestions from Public Health England (PHE) — a government agency for preventing ill health — include 400 calories for breakfast, 600 for lunch and 600 for dinner and this does not include drinks, the Daily Mail reported. For those who follow this, 200 calories in form of snacks can be taken.

The new amount is below the current recommended daily intake of 2,000 calories for women and 2,500 for men.

The new calorie guidelines — the One You nutrition campaign — will be rolled out by PHE in March, and adults will be told to remember the “400-600-600” rule.

Officials are also in talks with coffee shop chains and supermarkets to promote healthy breakfast and lunch options within the limit.

“We can no longer hide behind the charade that having a takeaway or eating out is merely a treat. Adults consume 200 to 300 excess calories each day and this calorie creep is contributing to weight gain and other serious health conditions,” a PHE spokesman was quoted telling the Daily Mail.

“This is why we’re working with high street chains to offer healthier options through our reduction programmes and new One You nutritional campaign,” the spokesman added.

Obesity rates for British men and women are at 27% — the highest in any country in western Europe.

An average adult is overeating by 300 calories a day, and this so-called “calorie-creep” is leading to a steady weight gain, officials said.

The guidelines “is a panic measure to get the public to understand they are eating too much”, Tam Fry, of the National Obesity Forum, was quoted as telling the Daily Mail.

“Portion sizes are getting bigger and bigger and people are mindlessly eating them just because they are there. The idea is sound because we are eating too much, but my feeling is the thresholds are too low,” Fry added.

However, the guidelines are merely a “rule of thumb” rather than strict limits, the government agency said.

Experts, on the other hand, have criticised the move. The calorie guidelines are “not based on evidence and are essentially a lie designed to manipulate people into eating less”, said Christopher Snowdon from the Institute of Economic Affairs think-tank. (IANS)

Obese? Blame it on Fat Cells’ Expansion

You have heard about obesity or accumulation of fat but do you know that nutrition is not the only factor driving obesity in our kids?

According to researchers, the mechanics of ‘cellular expansion’ plays a pivotal role in fat production.

To understand how obesity develops, a team from Tel Aviv University in Israel used state-of-the-art technology to analyse the accumulation of fat in the body at the cellular level.

“We wanted to find out why a sedentary lifestyle results in obesity, other than making time to eat more hamburgers,” said professor Amit Gefen from Tel Aviv University’s department of biomedical engineering.

“We found that fat cells exposed to sustained, chronic pressure – such as what happens to the buttocks when you are sitting down – experienced accelerated growth of lipid droplets, which are molecules that carry fats,” Gefen added.

Contrary to muscle and bone tissue, which get mechanically weaker with disuse, fat depots in fat cells expanded when they experienced sustained loading by as much as 50 percent. This was a substantial discovery.

The researchers discovered that, once it accumulated lipid droplets, the structure of a cell and its mechanics changed dramatically.

Using a cutting-edge atomic force microscope and other microscopy technologies, they were able to observe the material composition of the transforming fat cell, which became stiffer as it expanded.

This stiffness alters the environment of surrounding cells by physically deforming them, pushing them to change their own shape and composition.

“When they gain mass and change their composition, expanding cells deform neighbouring cells, forcing them to differentiate and expand,” he explained.

This proves that you are not just what you eat. You are also what you feel – and what you are feeling is the pressure of increased weight and the sustained loading in the tissues of the buttocks of the couch potato.

If you can learn to control the mechanical environment of cells, you can then determine how to modulate the fat cells to produce less fat, Natan Shaked from Tel Aviv University noted.

The team is now creating a platform to develop new therapies and technologies to prevent or even reverse fat gain, said the research published in the Biophysical Journal. (Bollywood Country)
