Leftovers may be throwing off your sense of how much you’ve actually eaten and how much you need to exercise, particularly as portion sizes—and therefore leftover portions—increase, according to a new study.

The brain has no nociceptors – the nerves that detect damage or threat of damage to our body and signal this to the spinal cord and brain. This has led to the belief that the brain feels no pain. A belief that has entered popular culture.

In the 2001 movie Hannibal, there is a gut-twisting scene in which the eponymous Hannibal Lecter cuts out part of the brain of an FBI agent who is fully awake, though drugged, and seated at a dinner table.

Worldwide obesity has tripled since 1975, with 1.9 billion adults considered overweight. The condition now kills more people across the globe than underweight and malnutrition.

One of the NHS’s biggest cost burdens, a staggering 70% of UK adults are expected to have overweight or obesity by 2034. Obesity is a problem of energy balance.

Nine in ten young women experience the cramping or stabbing of period pain just before their monthly bleed or as it starts.

Period pain (also called dysmenorrhoea) can be divided into two main types – primary or secondary dysmenorrhoea – depending on whether there’s an underlying problem.

Last week I had a shocking cold. Blocked nose, sore throat, and feeling poorly. This made me think about the countless vitamins and supplements on the market that promise to ease symptoms of a cold, help you recover faster, and reduce your chance of getting another cold. When it comes to the common cold (also called upper respiratory tract infections) there is no magic cure (I wish) but some supplements may deliver very minor improvements. Here is what the latest research evidence says.

Increasing the amount of exercise is one way to use the energy stored in fat cells, or to ‘burn’ fat. Many of us may be considering “burning some fat” so we feel better in our bathing suits out on the beach or at the pool. What does that actually mean, though?

The number of studies that have found a link between a disease and a specific gut microbiome composition seems to be ever increasing. Until recently, though, almost all these studies have looked at single diseases in isolation. But most people tend to have more than one health complaint at a time – “comorbidities”, in medical parlance.

Alcohol producers and retailers have long argued that their goal is a world where everyone drinks responsibly and heavy drinking is a thing of the past. As a result, the alcohol industry claims to be part of the solution to the UK’s drink problem rather than part of the problem. In our latest research, published in Addiction, we examine the credibility of this claim.

Members of a small women’s rights group, Liverpool ReSisters, have declared that “women don’t have penises”. They seem to be very confident of this point, having gone as far as to paste stickers claiming as much onto the genital areas of some of the statues that make up Anthony Gormley’s artwork Another Place on Crosby Beach near Liverpool. It’s an attention-grabbing stunt. But are they right? Well, it depends on what they mean by “women”.

It is highly unlikely that a butterfly or moth remembers being a caterpillar. However, it may well remember some experiences it learned as a caterpillar.

That fact in itself is especially amazing because inside the pupa (or chrysalis), the caterpillar actually turns to liquid as it transforms into a butterfly or moth (the adult stage).

Timing our meals can fend off diseases caused by bad genes or bad diet. Everything in our body is programmed to run on a 24-hour or circadian time table that repeats every day. Nearly a dozen different genes work together to produce this 24-hour circadian cycle. These clocks are present in all of our organs, tissues and even in every cell. These internal clocks tell us when to sleep, eat, be physically active and fight diseases. As long as this internal timing system work well and we obey them, we stay healthy.

We are still in love with vitamins a century after they were discovered, with half the US and UK population taking a supplement. Vitamin D – the sunshine vitamin – is the favourite and is believed to have the most proven benefits. Governments, including the UK government, have said that the evidence for vitamin D’s health benefits is so overwhelming that every adult should take it as a supplement for at least six months of the year.

A solid white mass found in a broken jar in an Ancient Egyptian tomb has turned out to be the world’s oldest example of solid cheese. Probably made mostly from sheep or goats milk, the cheese was found several years ago by archaeologists in the ancient tomb of Ptahmes, who was a high-ranking Egyptian official. The substance was identified after the archaeology team carried out biomolecular identification of its proteins.

Many parts of the country have seen episodic crises due to synthetic marijuana, the largest occurring in Mississippi, where 721 adverse events were logged between April 2-3, 2015. Even with outbreaks aside, synthetic cannabinoids are 30 times more likely to harm you than regular marijuana.

People with low muscle strength don’t typically live as long as their stronger peers, according to a new study. After adjusting for sociodemographic factors, chronic health conditions, and smoking history, researchers found that people with low muscle strength are 50 percent more likely to die earlier.

In general, women have greater absolute body fat percentages than men. Typically, women carry more fat around the legs, hip and buttocks, as well as the chest and upper arms. Women have more subcutaneous fat – the fat you can pinch under your skin – while men typically have more visceral fat, which is stored in and around the abdominal organs.

When those first fat drops of summer rain fall to the hot, dry ground, have you ever noticed a distinctive odor? I have childhood memories of family members who were farmers describing how they could always “smell rain” right before a storm. Of course rain itself...

Can you imagine a future where the question “Did you bring a copy of your test results?” becomes entirely unnecessary? That could happen, but the methods that most health care providers use to exchange health care information are little different than they were 5,000 years ago, when physicians caring for the same patient exchanged scrolls of papyrus and clay tablets.

Time-restricted eating (also called time-restricted feeding) is a new dietary concept that involves reducing the time between the first and last calorie consumed each day. There is strong evidence to support the health benefits of time-restricted eating (TRE) in animals, and recent small studies by our research group and others suggest possible benefits for humans, too.

Many older people find they’re not able to move as freely as they did when they were younger. They describe their movements as feeling stiff or restricted. In particular, feeling stiff when getting out of bed first thing in the morning or after sitting for a long period. The feeling does eventually ease with movement as the muscles “warm up”, but it can be troublesome. There are a few reasons this happens.
