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.

Protein shakes have become a popular part of modern fitness routines. From gym-goers to busy professionals, many people rely on them for muscle building, weight management, or convenience. But during extreme summer heat, excessive or careless use of protein supplements may place extra stress on the kidneys, especially when hydration is poor.

Why Summer Changes The Equation:

In hot weather, the body loses more water through sweating. If fluid intake is not enough, dehydration can occur silently. At the same time, a high-protein intake increases the amount of waste products like urea that the kidneys must filter and remove. This means the kidneys may have to work harder during the summer months.

High-protein diets can also increase uric acid levels and lower urine pH, creating conditions that may promote uric acid kidney stones, particularly in dehydrated individuals. When combined with intense workouts and inadequate hydration, the risk can rise further during summer.

For healthy individuals, moderate protein intake is usually safe. However, problems can arise when people consume multiple protein shakes daily, combine them with high-protein diets, fat burners, intense exercise, or poor water intake. This combination can increase the risk of dehydration, kidney stones, and kidney strain.

Who Should Be More Careful?

People with pre-existing kidney disease (CKD), diabetes, high blood pressure, obesity, or a history of kidney stones should be particularly cautious with protein supplements. In individuals with underlying CKD, excessive protein intake may worsen proteinuria, increase acid accumulation in the body, trigger uremic symptoms, and accelerate deterioration of kidney function.

Many individuals assume that “more protein means better fitness,” but excessive intake does not necessarily translate into more muscle gain.

Young fitness enthusiasts are also increasingly using supplements without professional guidance. Some over-the-counter products may contain added creatine, stimulants, sugars, or unregulated ingredients that can further burden the kidneys if taken improperly.

Warning signs not to ignore:

Persistent fatigue, swelling, reduced urine output, dark-colored urine, muscle cramps, nausea, or flank pain may indicate dehydration or kidney stress. Ignoring these symptoms during high heat can worsen the situation.

How To Use Protein Safely In Summer?

The safest approach is balance. Protein shakes should supplement a healthy diet, not replace meals entirely. Staying adequately hydrated is crucial, especially before and after workouts. Choosing medically approved supplements, avoiding excessive intake, and consulting a doctor or dietitian before starting long-term supplementation can help prevent complications.

Protein shakes are not inherently harmful, but in peak summer heat, hydration and moderation matter just as much as fitness goals.

Amid a global increase in hypertension cases, a new study showed that a higher intake of soy foods and legumes may significantly reduce the risk of developing high blood pressure.

Researchers, including those from King’s College London and the University of Winchester, UK, found that people who regularly consumed foods such as lentils, chickpeas, beans, tofu, soy milk, and edamame were less likely to develop hypertension compared to those with lower intake levels.

The findings, based on a new pooled data analysis published in BMJ Nutrition Prevention & Health, add to growing evidence that plant-based proteins may play an important role in protecting heart health.

"These findings provide further evidence in support of dietary recommendations to the public to prioritize and integrate legumes and soy foods as healthy protein sources in the diet," the researchers said in the paper.

How Legumes And Soy Helped Reduce High BP

The study analyzed data from 12 prospective observational studies involving participants from the United States, Europe, and Asia.

The team also identified an “optimal range” for daily intake. The reduction in hypertension risk was significant among:

• Those taking around 170 grams of legumes per day — 30 per cent reduction .
• Soy foods showed the greatest benefit at 60–80 grams daily — 28–29 per cent reduction.

The analysis showed that:

• A high intake of legumes reduced the risk of high BP by 16 per cent
• Higher soy consumption led to a 19 per cent lower risk of hypertension.

Why These Foods May Help

According to the researchers, legumes and soy's blood pressure-lowering benefits may be because these common foods contain nutrients known to support cardiovascular health, including:

• Potassium
• Magnesium
• Dietary fiber

Soy foods additionally contain compounds called isoflavones, which may further contribute to blood pressure regulation.

The researcher has called for further large-scale cohorts to confirm the findings, as hypertension rates continue to rise worldwide.

“Current legume consumption across Europe and the UK remains below dietary recommendations,” the authors noted, adding that average intake is far lower than the recommended levels for cardiovascular health.

The experts noted that the study’s dose-response analysis offers practical dietary targets that could help shape future public health guidelines and clinical recommendations.

However, they also cautioned that more large-scale studies are needed to confirm the findings and better understand why soy’s benefits appeared to plateau beyond 80 grams per day.

Oily and spicy foods are often a highlight of summer parties, but they can also lead to digestive issues, especially in hot weather. During summer, the body’s metabolism tends to slow down slightly as it focuses more on maintaining temperature balance. Heavy, greasy foods like fried snacks or rich curries take longer to digest, putting extra strain on the digestive system. This can result in symptoms such as bloating, heaviness, and discomfort.

Spicy foods, while tasty, can further aggravate the problem. Ingredients like chili peppers increase heat in the body, which may already be elevated due to the hot weather. This excess heat can irritate the stomach lining, leading to acidity, heartburn, or even loose motions in sensitive individuals. People who already have conditions like gastritis or acid reflux are more likely to experience worsening symptoms after consuming spicy dishes.

Dehydration And Food hygiene

Another important factor is dehydration. In summer, the body loses more fluids through sweating. Oily and spicy foods do not provide hydration and may even increase the need for water. If fluid intake is not sufficient, digestion becomes slower and less efficient. This can lead to constipation or a feeling of fullness for a longer time.

Food hygiene at parties also plays a role. Oily foods are often prepared in bulk and kept out for long periods. In hot temperatures, this increases the risk of bacterial growth, which can cause food poisoning, stomach cramps, vomiting, or diarrhea.

Balance Your Plate

To avoid these issues, it is better to balance your plate. Including lighter options like fruits, salad, grilled items, and plenty of water can help maintain digestion. Limiting the intake of deep-fried and overly spicy foods, especially during peak heat hours, can prevent discomfort.

In conclusion, while oily and spicy foods add flavor and enjoyment to summer parties, overconsumption in hot weather can disrupt digestion and lead to multiple gastrointestinal problems. Making mindful food choices helps you enjoy the party without compromising your health.
