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.

Link Between Metabolism and 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.

What Is a Ketogenic Diet?

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.

Fruits and vegetables are widely recommended to improve health and reduce the risk of cancer and other diseases. However, a new study claimed that eating a very healthy diet—packed with fruits, vegetables, and whole grains—can raise the risk of lung cancer.

Shockingly, the study showed that the risk of lung cancer with a healthy diet may be higher in younger non-smokers.

The research from the University of Southern California, presented at the annual meeting of the American Association for Cancer Research, found that patients under 50 diagnosed with lung cancer often had better-than-average diets.

The experts zeroed in on the culprit—pesticide exposure from conventionally grown produce.

"Our research shows that younger non-smokers who eat a higher quantity of healthy foods than the general population are more likely to develop lung cancer," said lead investigator Jorge Nieva, a medical oncologist and lung cancer specialist with USC.

"These counter-intuitive findings raise important questions about an unknown environmental risk factor for lung cancer related to otherwise beneficial food that needs to be addressed," Nieva added.

Pesticides In Healthy Foods — A Hidden Risk

According to the researchers, the reason may lie in environmental exposure, particularly pesticides used in agriculture. Nieva noted that commercially produced (non-organic) fruits, vegetables, and whole grains are more likely to carry higher levels of pesticide residue compared to dairy, meat, and many processed foods.

He also pointed out that agricultural workers who are regularly exposed to pesticides tend to have higher rates of lung cancer, which supports the possibility of a connection.

The study also found that young women who do not smoke are diagnosed with lung cancer more often than men in the same age group. Women in the study also tended to consume more fruits, vegetables, and whole grains than men.

What Is Lung Cancer?

Lung Cancer is one of the most common and serious types of cancer. It is also the leading cause of cancer-related deaths worldwide, with approximately 2.5 million new cases and 1.8 million deaths reported in 2022.

Traditionally, lung cancer occurs in older people. However, non-smokers age 50 and younger, particularly women, are now experiencing increasing rates of lung cancer and are more likely than men to develop the disease.

In many cases, there are no symptoms; however, one must look out for these:

• a persistent cough
• coughing up blood
• persistent breathlessness
• unexplained tiredness and weight loss
• an ache or pain when breathing or coughing.

Why More Research Needed

Nieva emphasized that more research is needed to confirm any link between pesticide exposure and lung cancer in younger people, especially women.

In this study, researchers did not directly measure pesticide levels in the foods participants ate. Instead, they estimated exposure using existing data on average pesticide levels in food categories such as fruits, vegetables, and grains.

Black coffee or an espresso shot is not everyone’s cup of tea, but for those who are already in love with it, giving it up can be difficult. This drink is a favourite among weight watchers, fitness enthusiasts, and especially people with type 2 diabetes. Diabetics, in particular, are often recommended black coffee because it contains almost zero calories per cup. Not only does it boost stamina, but it also works well to aid weight loss and manage blood sugar levels. Experts say that drinking three to five cups of black coffee a day can help boost levels of polyphenols, and these findings were published in the International Journal of Molecular Sciences.

Is coffee beneficial for diabetics?

For this, researchers compiled data from 149 publications and examined the effects of coffee on metabolic processes and the consequent development of type 2 diabetes. Researchers focused on five hydroxycinnamic acids in coffee and analysed the effects of polyphenols on the pancreas, small intestine, muscle, liver, and tissues. The analysis also showed that black coffee can help regulate blood sugar levels, have an anti-inflammatory effect, enhance insulin sensitivity, and improve glucose metabolism.

The study results were similar for both caffeinated and decaffeinated coffee, indicating that the benefits were derived from compounds other than caffeine. This was associated with a 20–30 per cent lower risk of type 2 diabetes in regular coffee drinkers. Researchers stated that further studies are required, but the benefits of drinking black coffee are evident.

What are the benefits of drinking coffee?

Bioactive compounds such as hydroxycinnamic acid derivatives and chlorogenic acid are found in coffee, and they have the potential to help prevent and manage type 2 diabetes. Researchers also found that coffee can be an integral part of a healthy lifestyle. However, experts expressed concern about the real-life applications of these findings.

The impact of coffee on type 2 diabetes risk

Black coffee essentially consists of coffee beans and hot water. One cup contains approximately three calories, making it ideal for weight loss purposes. Coffee beans contain about 200 compounds, most of which are beneficial for health. When consumed together in the form of black coffee, these compounds may have a combined beneficial effect. Therefore, these anti-inflammatory, weight loss-friendly, and blood sugar-related benefits make it a healthy choice for people with diabetes.

How should a diabetic drink black coffee for blood sugar management?

Dr Rajiv Kovil, Head of Diabetology and weight loss expert at Zandra Healthcare, said: “Black coffee can help people with diabetes if used in the right way. It has almost no calories, no sugar, and a very low glycaemic impact due to its low glycaemic index, so it does not spike blood sugar. It also contains natural compounds such as caffeine and antioxidants that may slightly improve insulin sensitivity and metabolism. In practice, we often see better sugar control when patients replace sugary drinks with plain black coffee. However, it is not a treatment or a magic solution. Too much coffee can disturb sleep, increase stress hormones, and actually worsen sugar control. The key is moderation — one to two cups a day, without sugar or cream. Think of black coffee as a supportive habit, not a replacement for medicines, diet, or exercise. Good diabetes care still depends on a structured, scientific approach, with coffee playing only a small but helpful role.”

Not eating junk food is a common reassurance many people offer when discussing their eating habits, often with a sense of confidence that their lifestyle is on the healthier side. Salads, fruit juices, brown bread, and low-fat snacks usually replace what is typically labelled as ‘unhealthy’.

However, despite these conscious choices, an increasing number of youngsters are being diagnosed with fatty liver disease. This raises an important question: if junk food isn’t the problem, then what is?

The answer often lies in what goes unnoticed. Hidden sugars, quietly present in foods marketed as healthy, are becoming a major but overlooked contributor.

What is NAFLD?

Fatty liver disease, or non-alcoholic fatty liver disease (NAFLD), is a condition in which excess fat builds up in the liver in people who consume little to no alcohol. Often referred to as a silent disease, it may not show clear symptoms in its early stages, but when it does, signs include persistent fatigue, mild discomfort in the upper right abdomen, unexplained weight gain, and abnormal liver function tests.

It is largely influenced by metabolic factors such as high sugar intake, obesity, insulin resistance, sedentary lifestyle, and diets rich in refined carbohydrates and processed foods. What makes this risk more concerning is the subtle presence of hidden sugars in everyday healthy foods.

How Hidden Sugars In Healthy Diets Are Driving Fatty Liver

What may appear as a balanced and “healthy” diet can often conceal hidden sugars that, over time, contribute significantly to the risk of fatty liver disease. It is important to know that:

• Healthy packaged foods aren’t always healthy: Breakfast cereals, granola bars, flavored yogurt, and protein snacks often carry added sugars that go unnoticed.
• Fruit juices can be misleading: Packaged juices often have high sugar content without fiber, making them harder for the liver to process.
• Low fat doesn’t mean low risk: Many low-fat or diet products add sugar to improve taste, quietly increasing overall intake.
• Small intake of sugar multiple times a day: Tea, coffee, biscuits, and quick snacks may seem harmless individually, but together create a high daily sugar load.
• Natural sugars: Honey, jaggery, and brown sugar are often overused under the assumption that they are safer, but they affect the liver in similar ways.
• Inactive lifestyle makes it worse: Without enough physical activity, excess sugar is more likely to get stored as fat in the liver over time.

How Can It Be Diagnosed And Treated?

NAFLD is often detected through tests like HbA1c, CMP (comprehensive metabolic panel), and liver function tests. Imaging methods such as ultrasound and elastography help assess fat buildup and liver stiffness.

The condition usually has no clear symptoms in its early stages and is often linked to excess sugar intake. Treatment mainly focuses on reducing hidden sugars, improving diet, and increasing physical activity. In severe cases, bariatric surgery may be considered. Managing weight and blood sugar is essential to prevent further liver and heart complications.

How To Manage Sugar For Fatty Liver?

People can opt for healthy choices by:

• Reducing packaged healthy foods, as they often contain added sugars
• Limiting packed fruit juices and sweetened drinks that increase the sugar load
• Checking food labels to identify hidden sugars in everyday items
• Prefer home-cooked meals to control ingredients and sugar intake
• Stay physically active to help the body use sugar efficiently

Fatty liver is no longer limited to those who consume junk food or alcohol excessively. It develops quietly but can be managed with the right awareness and habits.

Controlling sugar intake is key to protecting both liver and overall health in the long run. It is increasingly becoming a silent condition among individuals who believe they are making the right dietary choices. Understanding food labels, limiting processed foods, and being mindful of hidden sugars are essential steps toward prevention.
