A revolutionary study published in BJPsych Open has revealed compelling evidence that a ketogenic diet can have a major impact on mental and physical well-being in bipolar disorder patients. The study, conducted by Dr. Iain Campbell, PhD, Baszucki Metabolic Psychiatry Research Fellow at the University of Edinburgh, investigates how a metabolic-based intervention might represent an exciting new strategy for treating this serious mental illness.
The research is the first in Europe to use neuroimaging methods, namely magnetic resonance spectroscopy (MRS), to investigate changes in brain metabolism in people with bipolar disorder after a ketogenic diet. The imaging findings revealed decreases in excitatory neurotransmitters, which are normally increased in bipolar disorder. This indicates that the ketogenic diet can stabilize brain activity, possibly reducing mood swings and other symptoms of the condition.
The trial involved 27 participants diagnosed with bipolar disorder, 20 of whom successfully completed the 6-8 week program. A staggering 91% of these individuals maintained ketosis, the metabolic state where the body primarily burns fat for energy instead of carbohydrates. Those who provided consistent daily ketone and mental health assessments reported notable improvements in mood, energy levels, anxiety, and impulsivity.
Dr. Campbell, who personally adheres to a ketogenic diet himself in order to treat symptoms of bipolar disorder, discussed the importance of these results:
"We saw indicators of diminished excitotoxicity in the brain regions most implicated in bipolar disorder. These findings are consistent with the metabolic overdrive hypothesis that postulates energy dysregulation within the brain as central to the disorder. Treating the dysregulation by means of a ketogenic diet could be a game-changer in treatment-resistant patients.
Aside from the scientific evidence, personal accounts of study participants underscore the life-altering effect of a ketogenic diet.
"Quite literally, for the first time in years, I felt like my brain was finally fueled correctly," explained a participant.
Another participant called the diet "a lifeline, restoring my energy and sense of hope. I felt like I was finally healing my mind, not just coping with my bipolar symptoms."
One of the very vivid accounts described the impact of ketosis in terms of a relaxing mental atmosphere:
"Applying a ketogenic diet is akin to giving my mind a nice warm bath. The edginess disappears. I am more calm, more clear, and my brain function is restored again."
Aside from the psychological benefits of the study, the ketogenic diet was also seen to have beneficial effects on participants' physical health. Nineteen out of the 20 trial completers lost a total of 9.3 pounds (4.2 kg) on average and showed improvements in body mass index (BMI) and blood pressure.
These results are noteworthy in that numerous treatments for bipolar disorder, such as mood stabilizers and antipsychotic medications, have been linked to metabolic side effects of weight gain and risk of cardiovascular disease. In contributing to the reduction of such risks, a ketogenic diet may provide a double dividend for patients with bipolar disorder.
Although the ketogenic diet has previously been known largely for its utility in treating epilepsy that is treatment-resistant, it is a somewhat new area to explore in conditions of psychiatry such as in bipolar disorder. It has come to be known that metabolic imbalance is an underlying factor in causing psychiatric disorders as energy production deficiencies have been recognized to contribute towards neural excitability and mood disruption.
One of the important findings of the study is that people with bipolar disorder tend to have sodium levels higher than usual within their cells. Lithium, a standard mood stabilizer, acts partly by reducing these sodium levels. The ketogenic diet seems to do the same thing, offering a metabolic explanation for its beneficial effect on mood stabilization.
The ketogenic diet is a high-fat, low-carb diet that changes the body's main source of energy from glucose to ketones. As carbohydrate consumption is significantly decreased, the liver breaks down fats into ketones, which can be used as a substitute fuel by the brain and body.
First developed in the 1920s as a therapy for epilepsy, the ketogenic diet has been researched for its therapeutic applications in a variety of neurological and psychiatric disorders, including Alzheimer's disease, Parkinson's disease, and most recently, bipolar disorder.
There's a critical need for bigger replication studies and well-designed randomized clinical trials to follow up on these findings," added Dr. Campbell. "Our findings indicate that a ketogenic diet may be a useful adjunctive treatment for bipolar disorder, bringing new promise to patients who have difficulty with standard therapies.

Many people are now aware that microplastics have entered the food and drink we consume every day. Seafood, in particular, has been widely discussed, as studies have found plastic particles in nearly all samples of fish and shellfish tested.
Plastic production has been rising steadily since the 1960s, with around eight million metric tonnes entering the oceans each year. Over time, sunlight and wave action break this waste down into microplastics, tiny fragments measuring less than five millimetres. These particles persist in the environment and gradually move through the food chain.
Writing in The Conversation, environmental expert Catherine Rolph explains that while seafood has received most of the attention, it is far from the only source of exposure. Public awareness is growing, she notes, but microplastics are found in many everyday foods, often in higher amounts than people expect.
Chewing gum is one of the more surprising sources of microplastics. Most gum is made from a synthetic base containing plastics and rubber, along with added sweeteners and flavours. As the gum is chewed, microplastic particles are released. Research suggests that just one gram of gum can release hundreds of these particles.
Even gums labelled as natural appear to release similar amounts, which points to contamination during production or packaging. Studies also show that most microplastics are released within the first few minutes of chewing.
Salt may seem like a basic, natural ingredient, but studies show that microplastics are present in the vast majority of salt products tested worldwide. In fact, contamination has been found to be higher in some land-based salts, such as Himalayan salt, than in sea salt.
Experts believe much of this contamination occurs during processing and packaging. Plastic grinders can also add to the problem by releasing additional particles while grinding.
Microplastics have been detected in a wide range of fruits and vegetables. Very small plastic particles can enter plants through their roots, while larger fragments may settle on their surfaces.
Research has found that apples and carrots tend to contain higher levels compared to other produce, while leafy greens such as lettuce show lower contamination. Despite this, experts stress that the health benefits of fruits and vegetables remain far greater than the potential risks.
Hot drinks are another overlooked source of microplastic exposure. Tea leaves, coffee, milk, and disposable takeaway cups can all contribute to contamination. Heat increases the release of microplastics, which is why hot beverages often contain more particles than cold drinks. Using loose-leaf tea and reusable cups made from glass or metal can help reduce exposure.
While most seafood does contain microplastics, studies suggest the actual levels are often lower than people assume. Filter-feeding shellfish such as mussels have been found to contain relatively small amounts compared to some processed foods and drinks prepared using plastic materials.
Experts say completely avoiding microplastics is unlikely, but small changes can help reduce exposure. Storing food in glass containers, avoiding plastic packaging where possible, and using non-plastic grinders and utensils can make a difference.
Switching from bottled water to tap water may also lower intake, as studies suggest single-use plastic bottles release more microplastics than tap water.

As a harsh cold wave swept across North India, doctors noticed a quiet but worrying trend inside emergency rooms—more people were showing up dehydrated, even though temperatures were at their lowest. Health and Me spoke to Dr. Swadesh Kumar, Cluster Head – Emergency and Trauma Care & Casualty, Gurugram, to understand why winter dehydration is often missed and how it can turn dangerous if ignored.
Winter is usually associated with hot drinks, cozy layers and fewer reminders to sip water. According to Dr. Kumar, this mindset is exactly where the problem begins. “People assume that because they’re not sweating or feeling thirsty, their body doesn’t need as much water. That’s a misconception,” he explains.
During cold spells, thirst signals are naturally suppressed. At the same time, the body continues to lose fluids through dry air, indoor heating and even breathing. “The loss is gradual and silent, which makes winter dehydration harder to spot,” Dr. Kumar adds.
Hospitals across northern states reported a seasonal increase in dehydration-related complications during the cold wave. These weren’t always dramatic cases. Patients often came in with dizziness, fatigue, confusion or sudden changes in blood pressure.
“In many emergency visits, dehydration wasn’t suspected initially because there was no heat exposure or fever,” says Dr. Kumar. This delay allowed symptoms to worsen before treatment was started.
Low fluid intake doesn’t just cause weakness, it can aggravate underlying health problems. When the body is dehydrated, blood becomes thicker, increasing the risk of clot formation. This is particularly dangerous for older adults and people with heart disease.
Kidneys are also affected. Reduced hydration puts extra strain on them, sometimes leading to acute kidney injury. “We see patients with palpitations, fainting spells and extreme weakness, only to later realize dehydration is the root cause,” Dr. Kumar notes.
Winter illnesses further complicate the situation. Fever, rapid breathing and certain medications increase fluid loss. Yet many people intentionally avoid drinking water to reduce bathroom visits in the cold.
“This combination is especially risky for children and the elderly,” Dr. Kumar says. Children depend on caregivers for hydration reminders, while older adults naturally feel less thirsty. Both groups can slip into dehydration quickly during winter infections.
Room heaters and blowers dry out indoor air, leading to unnoticed moisture loss through the skin and breath. People spending long hours indoors often underestimate this effect.
Early signs like dry lips, headaches and muscle cramps are commonly ignored. By the time medical help is sought, dehydration may already have disrupted blood pressure or electrolyte balance.
Unlike summer dehydration, winter dehydration doesn’t come with intense thirst. Dark urine, reduced urination, constant tiredness and mild confusion are frequent clues but are often blamed on cold weather or poor sleep.
“In severe cases, dehydration can contribute to sudden falls, worsening chronic illnesses and emergency admissions,” Dr. Kumar warns.
Doctors advise treating hydration as a routine, not a response to thirst. Warm water, soups, stews and herbal drinks are practical winter options. Fruits with high water content also help, even when appetite is low.
“Monitor urine color, limit excess caffeine and be extra careful if you have a chronic condition,” Dr. Kumar advises.
The cold wave is a reminder that dehydration isn’t just a summer problem. Even in winter, the body needs adequate water to function, and ignoring that need can quietly turn into a medical emergency.

With 28 percent of adults in the UK now classified as obese and another 36 percent considered overweight, it is unsurprising that weight-loss injections have surged in popularity. Estimates suggest around 1.5 million people are currently using these jabs each month.
While the injections can lead to significant weight loss, experts warn that they come with notable risks and often fail to address the root causes of weight gain. Mike Wakeman, a researcher, pharmacist, and founder of Evera Nutrition, explained how these medications work and why they may fall short in the long term.
“These medicines mainly act by increasing two gut hormones, GLP-1 and GIP. These hormones reduce appetite, increase feelings of fullness, and slow stomach emptying,” he said. “The problem is that many people rely on medication alone.”
Wakeman pointed out that several underlying contributors to weight gain are frequently overlooked. “Stress, poor sleep, alcohol misuse, binge eating, and even certain medications or hormonal and medical conditions, such as an underactive thyroid, are often ignored when discussing weight issues,” he said. “If these factors are not addressed, they will still be present at the end of treatment and are likely to trigger weight regain.”
Recent research supports this concern. Studies have found that participants regained almost all of the weight they lost within a year of stopping weight-loss injections.
Side effects linked to weight-loss jabs are common and include nausea, vomiting, constipation, and acid reflux. More serious health issues have also been reported in some individuals. These include pancreatitis, gallbladder problems, and depression. Rapid weight loss can result in muscle loss, while hair thinning and vision problems have also been associated with the use of these injections.
According to specialists, growing scientific evidence suggests that certain natural ingredients may help support healthy weight loss when combined with proper diet and lifestyle changes, without the same side-effect profile seen with injections.
“The good news is that some natural ingredients can mimic the effects of GLP-1,” Mike said. “These include glucomannan, which is a type of fibre, along with resveratrol, hibiscus, green tea, berberine, curcumin, cinnamon, and mulberry.”
Explaining the science behind these ingredients, Wakeman broke down how each one may support weight management.
“Glucomannan is a natural fibre derived from the konjac root. It expands in the gut, helping you feel full, and may also increase GLP-1 levels,” he said, as per Mirror. “Resveratrol, found in foods such as grapes, has been shown to significantly reduce body weight, waist circumference, and BMI.”
“Hibiscus has been shown to reduce obesity, abdominal fat, and blood lipid levels,” he added. “Catechins like EGCG, found in green tea, have been linked to meaningful reductions in body weight, BMI, and waist circumference, particularly at higher doses and over longer periods, when combined with a healthy diet and exercise. They also help boost metabolism and fat burning.”
“Berberine is a plant compound that, according to a meta-analysis of 12 studies, reduces body weight, BMI, and waist circumference,” he said. “Curcumin, the active compound in turmeric, has also shown strong evidence. An umbrella meta-analysis covering 14 systematic reviews and 39 randomised controlled trials found that curcumin supplementation reduces body weight, BMI, and waist size, while also improving blood sugar and blood fat levels.”
“Cinnamon may help reduce weight by improving blood sugar control,” Wakeman continued. “A meta-analysis of 12 trials involving 734 people found that cinnamon intake lowered body weight, BMI, and waist circumference. Mulberry has also shown anti-obesity effects, including activating brown fat.”
Wakeman also noted that certain ingredients may work by slowing the breakdown of GLP-1 and GIP. “Some compounds may help inhibit Dipeptidyl Peptidase-4, or DPP-4,” he said. “DPP-4 is an enzyme that breaks down GLP-1 and GIP. When this enzyme is blocked, these hormones remain active for longer.”
Ingredients that may play a role in DPP-4 inhibition include curcumin, resveratrol, cinnamon, maritime pine bark extract, blackcurrant, mulberry, quercetin, and rosemary.
