Common mistakes people make with GLP 1 weight loss medications

27. February, 2026

The use of GLP 1 medications such as Ozempic and Mounjaro has increased significantly over the past year. However, experts warn that many people make the same mistakes, which can slow their progress. Here are the most common pitfalls and how to avoid them.

Seeing the medication as a quick fix

GLP 1 drugs are not designed to deliver instant results. They mimic a natural hormone that regulates appetite, slows digestion, and helps you feel full for longer. Weight loss happens gradually, and the body needs time to adjust to new hunger signals.

Expecting rapid results before a specific event

Some people begin treatment ahead of a wedding or another important occasion hoping for fast changes. Experts emphasize that steady, gradual weight loss is healthier and more sustainable over time.

Sticking to old eating routines

When appetite changes, many continue eating at the same times out of habit. According to weight loss specialist Alistair Murray, this is an opportunity to pause and ask whether you are eating out of physical hunger or routine.

Not taking advantage of reduced hunger

A decrease in hunger can be a turning point. It may be the right moment to rethink meal composition, moving from carbohydrate heavy breakfasts to smaller, more protein focused options that still provide satisfaction.

Failing to prioritize protein

Proper nutrition remains essential during weight loss. Health professionals recommend aiming for around 1.2 grams of protein per kilogram of body weight per day. If overall intake is reduced, each meal should be as nutrient dense as possible.

Overlooking the importance of fibre

Appetite suppression can result in lower fibre intake. Fibre plays a key role in digestion and overall health, making it an important part of a balanced approach while using GLP 1 medication.

Not drinking enough water

GLP 1 medications slow the rate at which food and fluids leave the stomach. This can make it harder to consume enough liquids throughout the day. Mild dehydration may worsen side effects such as nausea, headaches, constipation, and fatigue.

Skipping regular meals

Even with reduced appetite, maintaining a consistent eating pattern is recommended. Skipping meals during the day can lead to increased cravings and overeating later on.

Undereating during the day and overeating at night

Some people eat very little earlier in the day and compensate in the evening. This pattern can increase snacking and make it more difficult to establish stable, long term habits.

Focusing only on the number on the scale

The scale is only one measure of progress. Sleep quality, energy levels, and physical strength are also important indicators. Healthy weight loss should not result in extreme fatigue, muscle loss, or poor sleep.

Neglecting essential nutrients

It is possible to lose weight while still depriving the body of key nutrients. Unhealthy weight loss may increase the risk of issues such as hair loss, skin problems, and heart disease.

Assuming side effects will last forever

Common side effects of GLP 1 medications include nausea, vomiting, diarrhea, and reduced appetite. Dizziness, increased heart rate, infections, headaches, and indigestion can also occur. Experts note that side effects are often most noticeable at the beginning and tend to settle as the body adapts.

Not consulting a healthcare provider if symptoms worsen

Although many side effects are temporary, worsening symptoms should be discussed with a healthcare professional. Treatment with weight loss medication should be supervised to ensure safety and effectiveness.

Severe side effects linked to metformin taken by millions worldwide

Severe side effects linked to metformin taken by millions worldwide

Taking daily medication can feel routine, especially when it helps keep a chronic condition under control.

For many people living with type 2 diabetes, treatment becomes part of normal life, something rarely questioned once it begins.

Metformin is one of the most widely prescribed diabetes drugs in the world, used by an estimated 120 million people.

It is recommended as a first-line treatment by health authorities such as the NHS and supported by organisations including Diabetes UK.

The medication lowers blood sugar by improving how the body responds to insulin and reducing glucose production in the liver.

It is also sometimes prescribed during pregnancy for gestational diabetes and for women with polycystic ovary syndrome.

Common side effects

Although considered safe and effective, metformin often affects the digestive system. Frequently reported reactions include nausea, diarrhoea, stomach pain, reduced appetite and a metallic taste in the mouth. Health guidance recommends taking it with meals to reduce these symptoms.

Long-term use, particularly at higher doses, has been linked to vitamin B12 deficiency.

According to the NHS, low B12 levels can lead to extreme tiredness, tingling sensations, mouth ulcers and pale skin. Routine blood tests can help detect this early.

Rare but serious risks

Severe complications are uncommon but require urgent medical attention. These include lactic acidosis, a rare condition involving breathing difficulties, weakness and feeling unusually cold. Liver problems and severe allergic reactions may also occur.

Metformin is not suitable for everyone, particularly people with significant kidney or liver disease or heavy alcohol use.

Patients are advised to consult healthcare professionals before making any changes to treatment.

New study: Exercise has a significant positive effect for breast cancer patients undergoing chemotherapy

A major new research review shows that women with breast cancer experience improved quality of life if they engage in physical activity during chemotherapy.

The study has been published in the journal The Lancet Healthy Longevity.

The analysis is based on 21 scientific trials involving more than 3,000 women.

In these studies, patients who exercised during treatment were compared with patients who received standard care only.

Across the studies, the physically active women reported feeling better both physically and mentally.

Many forms of exercise

The researchers examined various types of exercise, including walking, cycling, strength training, and combinations of different activities.

No single type of exercise proved to be superior. The effect was positive regardless of the form of training, as long as it was structured and tailored to the individual.

The study differs from previous research by focusing on women undergoing chemotherapy, rather than on those who had already completed treatment.

Part of a broader approach

Chemotherapy can cause fatigue, muscle weakness, and psychological strain.

As a result, there is now greater focus on how patients feel during treatment, not only on survival.

According to researchers from the Sylvester Comprehensive Cancer Center at the University of Miami, the findings indicate that exercise can form part of the overall support provided to patients.

They conclude that physical activity under professional guidance can serve as a supplement to medical treatment and help strengthen quality of life during a difficult period.

Studies suggest possible link between tattoos and cancer

Studies suggest possible link between tattoos and cancer

Several scientific studies point to a possible connection between tattoo ink and an increased risk of certain types of cancer.

However, the findings are not conclusive, and researchers emphasize that a direct causal relationship has not yet been proven.

Studies indicate increased risk of lymphoma

A study published in 2024 in The Lancet showed that individuals with tattoos had a 21 percent higher risk of developing lymphoma, which affects the lymphatic system, a central part of the immune system.

Danish twin study shows significant difference

A Danish study involving nearly 2,700 twins, published in January 2025 in BMC Public Health, found that tattooed individuals had a 62 percent higher risk of skin cancer and nearly three times the risk of lymphoma when they had large tattoos.

Research remains inconclusive

Although several studies identify an association, they have not proven that tattoos directly cause cancer.

The findings demonstrate statistical correlations, but not documented cause and effect.

One study shows lower risk of melanoma

A study from December 2025 published in the Journal of the National Cancer Institute found that individuals with three or more large tattoos had a 74 percent lower risk of melanoma compared with individuals without tattoos.

Ink particles travel through the body

When ink is injected into the skin, microscopic particles can over time be transported through the lymphatic system and accumulate in the lymph nodes, where they may build up and create hidden inflammation.

The immune system reacts to the ink

The body perceives tattoo ink as foreign material and activates the immune system in an attempt to remove it, which may result in prolonged immune activation.

Animal studies show long-term inflammation

A study published in November 2025 in PNAS showed that tattoo ink in mice accumulated in specific immune cells within the lymph nodes.

The cells died and triggered a prolonged inflammatory response.

Ink may affect vaccine effectiveness

In the same mouse experiment, tattoo ink at the vaccination site altered the immune response to vaccines against COVID-19 and influenza.

Certain colors contain problematic substances

Black ink may contain polycyclic aromatic hydrocarbons, which are associated with an increased cancer risk, while red ink may contain azo dyes that can break down into potentially carcinogenic compounds when exposed to UV light.

Heavy metals may be present

Some types of tattoo ink may contain lead, cadmium, and mercury, as well as solvents and additives such as formaldehyde and phenol, which are associated with toxicity and allergic reactions.

Chronic impact on the body

The accumulation of ink and metals may trigger chronic immune activation, oxidative stress, and abnormal growth of lymphocytes, all of which are known risk factors for cancer.

Size may matter

While the Lancet study did not find a link between tattoo size and risk, the Danish study showed that tattoos larger than a palm were associated with nearly triple the risk of lymphoma compared with individuals without tattoos.

Laser removal is not the solution

Laser treatment fragments ink particles and may increase the spread of potentially carcinogenic substances to the lymph nodes.

The study in The Lancet showed that individuals who had undergone laser tattoo removal had a two-and-a-half-times higher risk of lymphoma.

Prevention and awareness are important

Experts recommend maintaining a healthy lifestyle with a balanced diet, smoking cessation, regular exercise, limited alcohol consumption, and effective sun protection.

Individuals with tattoos should use sunscreen with at least SPF 30, undergo regular skin examinations, and seek medical attention if they notice swollen lymph nodes or lumps in the body.

Price war in weight-loss market: Novo Nordisk slashes prices

The Danish pharmaceutical company is under pressure from its American competitor Eli Lilly.

In particular, Lilly’s drug Zepbound has strengthened the rival’s position, the Financial Times reports. The price of Zepbound exceeds $1,000 per month.

At the same time, Novo has faced negative reactions to new trial results for CagriSema, a new treatment for obesity.

According to the Financial Times, the trials showed a lower average weight loss compared with similar treatments from Eli Lilly.

Several analysts believe this could make it more difficult for Novo to compete.

CagriSema has not yet been approved in the United States. A regulatory decision is expected later this year, according to the newspaper.

Price to be reduced

Amid the competition, Novo has decided to cut the price of Wegovy in the United States by 50 percent starting in January 2027. The price of the diabetes drug Ozempic will be reduced by 35 percent.

The new wholesale price of Wegovy will be $675 per month. This applies to both injections and tablets.

According to the newspaper, the aim is both to strengthen Novo’s position against Eli Lilly and to provide more patients with access to the medication through Medicare, the U.S. health program for older adults.

New trials in China

At the same time, Novo is working on new products. The company has published results from a study in China of a new weight-loss drug.

Participants lost an average of nearly 20 percent of their body weight over 24 weeks, the Financial Times writes.

An analyst cited by the newspaper says the results appear promising, but that the development is still at an early stage.

Overall, the developments show that Novo is both adjusting prices and investing in new medicines in order to maintain its position in the United States.

Results from 159,000 participants suggest this diet may reduce the risk of cognitive decline

Results from 159,000 participants suggest this diet may reduce the risk of cognitive decline

In an analysis published in JAMA Neurology on February 23, 2026, and reported by Powers Health, researchers examined the link between diet and brain aging.

The study is based on data from three large U.S. longitudinal studies involving more than 159,000 nurses and health professionals.

Participants’ dietary habits were assessed according to six different healthy dietary patterns.

The results were then compared with their self-assessments of memory and mental abilities in old age.

The Importance of diet

An 11 to 24 percent lower risk of cognitive decline was observed among individuals who followed several of the healthy dietary patterns examined.

The strongest association was found with the DASH diet, which was developed to lower blood pressure.

Those who adhered most closely to this diet had a 41 percent lower risk of cognitive decline compared with those who adhered to it the least.

The effect was particularly evident among individuals aged 45 to 54.

According to the research team, led by Kjetil Bjornevik from the Harvard T.H. Chan School of Public Health, higher intake of vegetables, fish, and moderate wine consumption was associated with better brain function.

In contrast, red and processed meat, fried potatoes, and sugary drinks were linked to poorer outcomes.

Heart and brain

According to dietitian Stephanie Schiff from Northwell Health, the explanation may be that healthy blood pressure protects blood vessels, including those supplying the brain.

High blood pressure can damage blood vessels and reduce oxygen supply to the brain, which over time may affect memory and thinking.

The study therefore suggests that healthy eating habits in midlife may be an important part of maintaining brain health in old age.

New analysis: Six out of ten women may be overweight in 2050

According to an analysis published in the journal Circulation, many American women could face serious health problems in the coming decades.

High blood pressure is expected to rise most among Hispanic women, while obesity may increase most among Asian women.

Black women are projected to continue having the highest rates of high blood pressure, obesity, and diabetes in 2050. Around 40 percent of Black girls may be overweight by that time.

Social factors such as poverty, low levels of education, and living in rural areas influence the risk of disease.

Problems begin early

The trend does not affect adults alone. Nearly 32 percent of girls aged 2 to 19 may be overweight in 2050.

Lack of physical activity and unhealthy diets are cited as key causes.

At the same time, more than 25 percent of women may have diabetes in 2050, compared with around 15 percent today.

More than 60 percent may be overweight, and nearly 60 percent may have high blood pressure.

Prevention is important

Cardiovascular disease is already the leading cause of death among women in the United States.

One in three women dies from these diseases, and more than 62 million women live with some form of cardiovascular disease. The annual costs amount to at least 200 billion dollars.

According to the American Heart Association, up to 80 percent of cardiovascular diseases and strokes can be prevented through healthier habits such as improved diets, increased physical activity, and smoking cessation.

Overall, the analysis shows that a large proportion of American women could develop cardiovascular disease within the next 25 years if the trend continues.

A similar development may also be seen in other countries.

Study explores connection between caffeinated drinks and dementia

Study explores connection between caffeinated drinks and dementia

How many cups of coffee a day could lower your dementia risk? Harvard researchers point to a specific number

That first cup of coffee often feels like fuel for the brain. It sharpens focus, lifts mood and helps you power through the morning. But growing evidence suggests it may also influence how your brain ages.

A large study from Harvard University has examined whether daily caffeine intake is linked to dementia risk.

Decades of data

Researchers analyzed health information from more than 130,000 men and women enrolled in the Nurses’ Health Study and the Health Professionals Follow-up Study.

Participants were tracked for up to 43 years, and more than 11,000 developed dementia during that period. The results were published in JAMA.

The data showed that people who regularly consumed two to three cups of caffeinated coffee per day had a 15 to 20 percent lower risk of developing dementia compared with those who rarely drank coffee or tea.

Similar results were seen among those who drank one to two cups of caffeinated tea daily. Decaffeinated coffee was not associated with reduced risk.

Not a magic cure

Because the research is observational, it cannot prove that coffee directly prevents dementia. Other lifestyle habits may contribute to the difference.

Scientists suggest that caffeine and polyphenols, natural antioxidants found in coffee and tea, may help reduce inflammation and support metabolic health, both linked to brain aging. However, excessive caffeine can raise blood pressure, another known dementia risk factor.

Experts emphasize moderation and a healthy lifestyle, including exercise, balanced nutrition and adequate sleep, as the most reliable ways to support long-term brain health.

Doctor outlines physical symptoms associated with dementia

Doctor outlines physical symptoms associated with dementia

Dementia is most commonly associated with memory loss and language difficulties. However, the condition can also manifest through a range of physical changes that are not always immediately linked to cognitive decline. A US geriatrician highlights several signs that may signal the disease.

Balance and walking may be affected

Difficulty walking steadily or maintaining balance can be an early warning sign. According to Dr Stephanie Nothelle, a geriatrician and associate professor at Johns Hopkins School of Medicine in Baltimore, smooth and coordinated movement requires significant cognitive control. Changes in this ability, particularly alongside other symptoms, may indicate dementia.

Physical symptoms often appear later

Many of the more noticeable physical changes tend to occur in the later stages of dementia. Nevertheless, certain mobility issues can emerge earlier in the progression of the disease.

Swallowing difficulties can develop

Dementia may impair essential motor functions involved in swallowing. This can cause food or liquids to go down the wrong way during meals.

Risk of food entering the lungs

When food passes into the airways instead of the oesophagus, it can become lodged in the lungs. This may lead to serious health complications.

Pneumonia is more common in later stages

If bacteria from food enter the lungs, it can result in aspiration pneumonia. For this reason, pneumonia is relatively frequent among people in the advanced stages of dementia.

Loss of bladder control

As the condition progresses, control over bodily functions can weaken. Incontinence can therefore become a symptom of dementia.

Nerve degeneration affects bladder function

Dr Nothelle explains that incontinence occurs because the nerves responsible for controlling the bladder gradually deteriorate as dementia advances.

Shuffling gait in Lewy body dementia

In dementia with Lewy bodies, cognitive symptoms typically appear before physical ones. Once physical changes develop, posture may worsen and walking can become slower and more shuffling.

Protein deposits in the brain

Lewy body dementia develops when clusters of proteins accumulate in nerve cells in the brain. According to Dementia UK, this type accounts for around 10 to 15 percent of dementia diagnoses, and possibly up to 20 percent.

Rigidity and freezing episodes

Common signs of Lewy body dementia include slowed movement, difficulty walking, shuffling steps, stiffness, and episodes where a person suddenly freezes mid movement.

Changes in smell and taste

Alterations in the senses of smell and taste are also associated particularly with Lewy body dementia.

Increased drooling

The condition may lead to greater saliva production, making a person more prone to drooling.

Disrupted sleep cycle

Dementia can interfere with the brain’s ability to distinguish between day and night, disrupting the natural sleep wake cycle.

Restless nights and more daytime sleep

According to the Alzheimer’s Society, people with dementia may struggle to fall asleep, wake frequently during the night, and sleep more during the day due to physical changes occurring in the brain.

Health experts warn against excessive bubble tea intake

Health experts warn against excessive bubble tea intake

It is colourful, sweet and almost impossible to scroll past on social media without craving one. For many young people, it has become part of everyday life.

But health experts are increasingly questioning whether this trendy favourite deserves its innocent reputation.

Hidden health concerns

Bubble tea, created in Taiwan in the 1980s, typically blends tea, milk, sugar and tapioca pearls made from cassava starch. Recent investigations have raised concerns about what may be hiding in the cup.

Consumer Reports detected elevated lead levels in some bubble tea products in the United States. Cassava plants can absorb heavy metals from soil, which may end up in tapioca ingredients.

Doctors also warn that the chewy pearls can create digestive issues. Because they are dense and slow to break down, they have been linked to delayed stomach emptying and, in rare cases, intestinal blockages. Pediatricians further caution that the pearls pose a choking risk, even for adults.

Sugar and long term impact

A single serving can contain 20 to 50 grams of sugar, rivaling or exceeding many soft drinks. Studies in Taiwan have associated frequent consumption among children with higher rates of tooth decay.

High sugar intake increases the risk of obesity, type 2 diabetes and fatty liver disease.

In 2023, doctors in Taiwan treated a young woman who developed hundreds of kidney stones after regularly replacing water with bubble tea, an extreme but cautionary case.

Emerging research in China has also suggested links between frequent consumption and symptoms of anxiety and low wellbeing.

Experts stress that bubble tea is best treated as an occasional indulgence rather than a daily habit.
