It’s long been popular advice for people looking to lose weight to avoid late night snacking. It’s no wonder, with a host of research showing that late night eating is linked to greater body weight and increased risk of obesity.

But until now, few studies have actually investigated precisely why late night eating is linked to greater body weight. This is what a recent US study set out to uncover. They found that eating four hours later than normal actually changed many of the physiological and molecular mechanisms that favour weight gain.

This work adds to other recently published work which has found that eating earlier in the day is more beneficial for both appetite and body weight control.

Late eating

To conduct their study, the researchers had 16 participants follow two different meal schedules, each for a period of six days total.

The first protocol had participants eat their meals early in the day with the last meal consumed approximately six hours and 40 minutes before bedtime. The second protocol had participants eat all of their daily meals approximately four hours later. This meant they skipped breakfast and instead had lunch, dinner and an evening meal. Their last meal was consumed only two and a half hours before sleep.

The study was conducted in a controlled lab, which ensured the participants in each group consumed an identical diet, and that all of their meals were evenly spaced with around four hours between them.

To understand how late eating affected the body, the researchers specifically looked at three different measures which are associated with weight gain:

  1. The influence of appetite,
  2. The impact of eating time on energy expenditure (calories burned), and
  3. Molecular changes from fat tissue.

Appetite was measured using two techniques. The first technique was having participants rate their feelings of hunger throughout the day. The second technique was by collecting blood samples to look at the levels of appetite-regulating hormones in participants’ blood – such as leptin (which helps us feel full) and ghrelin (which makes us feel hungry). These hormones were assessed hourly over a 24 hour period during the third and sixth day of each trial.

To assess the effect of meal timing on daily energy expenditure, a technique called “indirect calorimetry” was used. This measures both the amount of oxygen a person uses alongside the amount of carbon dioxide they produce. This helps researchers estimate how many calories a person’s body uses throughout a normal day.

To examine how late night eating affects the way the body stores fat on a molecular level, the researchers performed a biopsy on fat tissue taken from the abdomen. Only half of the participants agreed to this.

The team found that compared to an early eating pattern, late eating not only increased subjective feelings of hunger the following day, it also increased the ratio of “hunger” hormones in the blood – despite participants eating an identical diet in both protocols. Late eating also caused a decrease in the number of calories burned the following day. In the participants who did the fat tissue biopsy, late eating was also shown to cause molecular changes that promote fat storage.

Together, these results indicate that late eating leads to a number of physiological and molecular changes that, over time, could lead to weight gain.

Potential for weight gain

While we don’t fully understand all of the mechanisms underlying why late night eating promotes weight gain, this study shows us that it’s probably the result of many factors working together.

One theory for why eating late causes weight gain could be due to our circadian rhythm. The human body has a natural circadian rhythm, which is controlled by the brain to influence the normal ebb and flow of hormones. It’s particularly responsive to daylight and food intake.

Time of eating is intrinsically linked to the circadian rhythm in humans, as we normally sleep when it’s dark out and eat when it’s daylight. When we eat late, this could challenge the natural circadian rhythm, causing disruptions to the body’s hunger signals and the way it uses calories and stores fat. However, this link has only been shown in studies on animals thus far.

Given the new study was only conducted on a limited number of participants and over a very short time frame, more research will be needed to further understand whether these changes are only temporary, and what affect long-term late night eating can have on these weight gain mechanisms. But we do know from other studies that people who tend to eat late in the evening also tend to gain weight more easily.

Other large-scale studies looking at the relationship between disturbances in meal timing on energy balance (such as skipping breakfast, late night eating and shift work) have found these patterns of eating were linked to higher body weight and greater risk of metabolic disorders (such as high blood pressure or type 2 diabetes).

This study adds to a growing body of evidence showing just how important meal timing can be when it comes to body weight. Based on what this and other studies have shown, people who are watching their weight may want to ditch the late night snacks and favour of eating most of their meals earlier in the day.The Conversation

The situation surrounding his death is not clear, but sources told the newspaper that the corpse is expected to be flown to Nigeria in the coming days.
 
 
A former Senate President, David Mark has lost his first son, Tunde Mark.
 
A report by Daily Sun, quoted a family source who said that Tunde died in the early hours of Friday in London, the United Kingdom.
 
Tunde is said to have suffered from cancer and died at the age of 51 years.
 
The situation surrounding his death is not clear, but sources told the newspaper that the corpse is expected to be flown to Nigeria in the coming days.
 
Before his death, Tunde was an alumnus of Yaba Military School, Lagos, and the prestigious Fernden Prep School, Haslemere, Surrey.
 
He obtained a B.Sc degree from Kings College, London. Later he proceeded to study Biological Sciences at the Graduate School of Arts & Sciences, Harvard, and Cambridge, Massachusetts.
 
He left behind a wife and a child.

Anambra State Governor, Professor Chukwuma Soludo, has announced payments by families burying their loved ones, before they can paste posters of the deceased.

A letter by the Managing Director/Chief Executive Officer (CEO) of Anambra State Signage and Advertisement Agency, Mr Tony Odili Ujubuon͂u, communicating this to community leaders was sighted by DAILY POST.

The letter stated a tax of N100,000 for display of burial banners across the state, and varying amounts for posters and other sizes of banners.

The letter to the national chairman of Anambra State Association of Town Unions (ASATU) read: “The tariff below serves as a guide to what is payable; sizes, description, amount and duration of the taxes are: 4 X 6FT N5,000 for 2 weeks; 8 X 10FT N20,000 for 2 weeks; above 10FT square are N100,000 monthly; and N5000 for posters for 2 weeks.

“Note that directional signs leading to the venue which can come in 1x 2ft size will not be charged. It is also important to bear in mind that after the duration of this period, any such board that is left standing will attract a penalty in the sum of the amount initially paid. This penalty is paid weekly.

“The Agency, in fulfillment of its statutory obligation, is not unmindful of the menace associated with non-commercial adverts that have literally occupied our out-of-home space. These adverts come in the form of obituary, religious, wedding and sundry flex, banners and posters.”

The agency said the reason for this was to curb the level at which people deface the environment, which has become a threat to the aesthetics of communities.

It said it will work with the town union to collect payment and also enforce it, adding that Soludo has the resolve of making Anambra a liveable city.”

The agency said communities, villages, hamlets, kindreds, churches and town unions would be alerted of the latest development.

Addressing the national chairman of ASATU in the letter, Ujubuonu said: “We have written to you because we have always regarded you as progress partners in the development of Anambra State.”

While promising to prioritise projects in Southeast, Atiku took a swipe at the All Progressives Congress(APC)-led administration for segregating some parts of the country with the paucity of projects.

 
 
The presidential candidate of the Peoples Democratic Party (PDP) Atiku Abubakar has pledged to support Igbos produce the next president of Nigeria after him, according to a report by TheNation.
 
The politicians also vowed to prioritise developmental projects in Southeast and other regions when elected, saying that any project in any State is a favour to Nigeria.
 
Atiku, who was addressing Southeast PDP stakeholders in Enugu on Tuesday, said: “I am the stepping stone for Igbos to become President of Nigeria”.
 
The PDP candidate, who maintained that he would win the 2023 presidential polls, said his great relationship with the Igbos would continue until they assume the presidency after his tenure.
 
“I’ve had close relationship with the Igbos and this influenced my choices of Senator Ben Obi and Mr. Peter Obi as my running mates in my two previous outings as presidential candidate. Again, I have chosen another great Igbo here (Dr. Ifeanyi Okowa) for the third time as my running mate.
 
“I have three Igbo children and I am saying this for the very first time in public. So, my relationship with Ndigbo did not start today,” Atiku said.
 
While promising to prioritise projects in Southeast, Atiku took a swipe at the All Progressives Congress(APC)-led administration for segregating some parts of the country with the paucity of projects.
 
“The second Niger bridge in Onitsha is not a favour to the Southeast, rather it is or should be seen as a favour to Nigeria. This is because it is not only the people of the Southeast that use the bridge,” Atiku said.
 
He also expressed concern over the ongoing sit-at-home in the region which he said had dealt a big blow to the economy of the region and the country at large, calling on elders in the region to speak out against it.
 
He said his administration would pay close attention to tackling insecurity, economic and other challenges bedeviling the country.

It will be disingenuous to dismiss as useless and evil, all the consequences of the British invasion of our land.

Coffee – one bean with many possibilities. A big choice is how to brew it: espresso, filter, plunger, percolator, instant and more. Each method has unique equipment, timing, temperature, pressure, and coffee grind and water needs.

Our choices of brewing method can be cultural, social or practical. But how much do they really impact what’s in your cup?

Which is the strongest brew?

It depends. If we focus on caffeine concentration, on a milligram per millilitre (mg/ml) basis espresso methods are typically the most concentrated, able to deliver up to 4.2 mg/ml. This is about three times higher than other methods like Moka pot (a type of boiling percolator) and cold brewing at about 1.25 mg/ml. Drip and plunger methods (including French and Aero-press) are about half that again.

Espresso methods extract the most caffeine for a few reasons. Using the finest grind means there is more contact between the coffee and water. Espresso also uses pressure, pushing more compounds out into the water. While other methods brew for longer, this doesn’t impact caffeine. This is because caffeine is water soluble and easy to extract, so it’s released early in brewing.

But these comparisons are made based on typical extraction situations, not typical consumption situations.

So, while espresso gives you the most concentrated product, this is delivered in a smaller volume (just 18–30ml), compared to much larger volumes for most other methods. These volumes of course vary depending on the maker, but a recent Italian study defined a typical final serve of filter, percolator and cold brews as 120ml.



Based on this maths, cold brew actually comes out as the highest dose of caffeine per serve with almost 150mg – even higher than the 42–122mg totals found in finished espresso. Although cold brew uses cold water, and a larger grind size, it is brewed with a high coffee to water ratio, with extra beans needed in the brew. Of course, “standard serves” are a concept not a reality – you can multiply serves and supersize any coffee beverage!

With the rising price of coffee, you might also be interested in extraction efficiency – how much caffeine you get for each gram of coffee input.

Interestingly, most methods are actually pretty similar. Espresso methods vary but give an average of 10.5 milligrams per gram (mg/g), compared to 9.7–10.2mg/g for most other methods. The only outlier is the French press, with just 6.9mg/g of caffeine.

‘Strength’ is more than just caffeine

Caffeine content only explains a small part of the strength of coffee. Thousands of compounds are extracted, contributing to aroma, flavour and function. Each has their own pattern of extraction, and they can interact with each other to inhibit or enhance effects.

The oils responsible for the crema – the rich brown ‘foam’ on top of the brew – are also extracted more easily with high temperatures, pressures, and fine grinds (another potential win for espresso and Moka). These methods also give higher levels of dissolved solids, meaning a less watery consistency – but, again, this all depends on how the final product is served and diluted.

To further complicate matters – the receptors that detect caffeine and the other bitter compounds are highly variable between individuals due to genetics and training from our usual exposures. This means the same coffee samples could invoke diverse perceptions of their bitterness and strength in different people.

There are also differences in how sensitive we are to the stimulant effects of caffeine. So what we are looking for in a cup, and getting from it, is dependent on our own unique biology.

Is there a healthier brew?

Depending on the headline or the day, coffee might be presented as a healthy choice, or an unhealthy one. This is partly explained by our optimism bias (of course we want coffee to be good for us!) but may also be due to the difficulty of studying products like coffee, where it is difficult to capture the complexity of brewing methods and other variables.

Some studies have suggested that coffee’s health impacts are brew type specific. For example, filter coffee has been linked to more positive cardiovascular outcomes in the elderly.

This link might be a coincidence, based on other habits that coexist, but there is some evidence that filter coffee is healthier because more diterpenes (a chemical found in coffee which might be linked to raising levels of bad cholesterol) are left in the coffee and the filter, meaning less make it to the cup.

The bottom line?

Each brewing method has its own features and inputs. This gives each one a unique profile of flavour, texture, appearance and bioactive compounds. While the complexity is real and interesting, ultimately, how to brew is a personal choice.

Different information and situations will drive different choices in different people and on different days. Not every food and drink choice needs to be optimised!The Conversation

 Presidential candidates

Kingsley Wali, the Convener of Unity House Foundation (UHF), an advocacy group, has slammed Nigeria's presidential candidates.

The man slammed the presidential candidates of the 2023 polls who were present at the 2022 Annual Conference of the Nigerian Bar Association (NBA), for turning the venue of the event into a campaign ground, in contravention of the electoral law.

Wali, a Port Harcourt-based businessman, said it was extremely appalling and nauseating to see people who are seeking to lead the country openly campaigning in such a gathering watched by the whole world, when the electoral umpire had not blown the whistle for the commencement of electioneering campaigns.

The UHF Convener spoke to SaharaReporters on Friday, while reacting to the conduct of the presidential candidates at the NBA event on Tuesday, adding "a man who is lawless is unlikely to offer quality service to the people."

He said, "If you don't have regard for the laws of the land, I don't know how to expect that you are going to obey the law or you are not going to circumvent the law or even suppress the law of the land when you become President, Governor or whatever."

Wali, who disclosed his group was working towards embarking on a crusade for violence-free campaigns ahead of the 2023 general election, said that the Independent National Electoral Commission (INEC) has not lifted the ban on campaign based on the electoral law, until September 28, 2022.

He said, "Let me start by saying that the Unity House Foundation which I am a member of, will from the second week of September, embark on a campaign for a violence-free electioneering in both the campaigns and the election proper. We intend to engage the public and the political class on the need to be civil, the need to focus on what the issues are and the need for them to be law-abiding too.

"But I won't fail at this point to mention that I'm a bit disappointed with the fact those who intend to lead Nigeria have started their campaign by breaking the laws of the land. A man who is lawless is unlikely to offer quality service to the people. If you don't have regard for the laws of the land, I don't know how to expect that you are going to obey the law or you are not going to circumvent the law or even suppress the law of the land when you become President, Governor or whatever."

He maintained that those who are jostling to lead the country beyond 2023, Atiku Abubakar of the Peoples Democratic Party; Bola Tinubu of the All Progressives Congress and the Labour Party’s Peter Obi, had all started badly by disobeying the laws of the country.

"INEC has not lifted the ban on campaign based on the electoral law. The ban on campaign will be lifted on the 28th of September. But those who are pretending to be leaders or those who want to get into power to lead Nigeria have started very badly by disobeying the laws of the land. I was very disgusted when I saw politicians openly violating the electoral law by campaigning for votes at the Nigerian Bar Association (NBA) Annual General Conference.

"It was as disgusting, as irritating and as despicable as you can imagine, that some people who are going to be the number-one defender of the laws of the land if elected President are violating the laws of the land by openly campaigning for votes very much against the law that is governing the electoral process," he added.

Speaking further, he said, “It is an indication of the kind of characters that want to lead the country. If you cannot obey the laws of the land, how do I believe that you can hold the laws of this country in trust for the Nigerian people. So, these are the kinds of things that scare me.

"If you cannot obey the laws of the land and you say you want to be a president and you started by flouting the laws and guidelines for the electoral process, why should I trust you with power? And it wasn't something that was done in some inconsequential gathering, but such a platform where the international community was watching and you saw people recklessly campaigning for votes when the ban on campaigns has not been lifted.”



 

It was gathered that hard times fell on the deceased who was a car seller before his demise. It is reported that he was in debts and couldn’t cope leading him to take the action of ending it all.

In a video circulating on social media, Afolabi can be seen appealing to his relatives to forgive him for his actions stating that he didn’t want to stress or involve them in his huge debt cr#sis

However, a di§turbing picture indicates that he ended it all by from a rope attached to a fan in his living room. The deceased is survived by a wife and a daughter.

 
 

The woman in the picture allegedly contacted these two men to eliminate her husband and take his Range Rover Jeep to her brother in Anambra, as instructed by the supposed wife of the victim.

Unfortunately, they were arrested by policemen in Ogun state on their way to deliver the Range Rover, after butchering the man, they thought he was dead, but luck on his side, he survived.

 
 

 

The couple, who are left with their eight-year-old daughter, Esther, said life had been difficult for them after the tragedy.

Chukwudi Micheal and Bolani Micheal, a Lagos couple has cried out for help.

The couple who lost four of their children to a midnight fire, have now sought the help of Nigerians.

PUNCH Metro had reported that the fire gutted the couple’s two-room apartment on Tapa Road, Oke-Oko, Isawo, in the Ikorodu area of Lagos State, on June 26.

Four children: Jeremiah, 12; Prayer, 18; Trust in God, 14; and Ebube, 10, died in the inferno.

The couple, who are left with their eight-year-old daughter, Esther, said life had been difficult for them after the tragedy.

The father of the children, Chukwudi, said the family had been struggling as their property and business were destroyed in the fire.

He said, “The fire incident not only claimed the lives of our children, but also took our means of livelihood. We do not know how to move on from here.

“God has been our support but we need Nigerians to help us get back on our feet. The sudden incident left us with no room to prepare. While nursing the heartache of losing our boys, we have to find our footings.”

His wife, Bolani, stated that the family was in distress.

She said, “We don’t know where to begin because we don’t have a place to stay and we are currently living with our pastor. Thank God for some good Samaritans who gave us clothes and some items to manage. We can’t always live with our pastor; we just pray that God will bring us back on our feet again.”
