You’ve waved goodbye to cookies, chips, and everything else that comes in a shiny wrapper, but the scale refuses to budge. It can be disheartening when cutting out processed foods doesn’t translate into immediate weight loss.

While eliminating junk food is an essential first step, weight loss often requires more nuanced adjustments. Studies, including a 2019 publication in Cell Metabolism, reveal that processed foods can lead to increased calorie consumption — about 500 extra calories daily compared to whole, unprocessed diets. While cutting out junk food is a commendable step, achieving sustainable weight loss requires a holistic approach.

But sometimes, ditching junk food isn’t enough. Here are five key reasons why your weight loss journey may be stalling, and how you can get back on track.

1. Your Sleep Schedule Is Sabotaging Your Goals

The connection between sleep and weight is often overlooked but crucial. Both too much sleep (over 9 hours) and too little (under 5 hours) can disrupt your body’s production of appetite-regulating hormones, such as leptin and ghrelin. This hormonal imbalance can increase cravings and overeating, particularly for high-calorie foods.

Additionally, poor sleep can leave you feeling fatigued, making it harder to stick to exercise routines.

How to Fix It: Aim for 7–8 hours of quality sleep per night. Establish a consistent bedtime routine and minimize screen time before bed to improve sleep hygiene.

2. Liquid Calories Are Sneaking Into Your Diet

You may have switched to a "healthier" drink lineup, but beverages like fruit juices, sugary coffee drinks, and wine can contain hidden calories that derail progress. Even organic fruit juices, often marketed as healthful, are loaded with sugar and lack the fiber found in whole fruits.

How to Fix It: Stick to water, unsweetened tea, black coffee, or sparkling water. To manage hunger, drink two cups of water 30 minutes before meals—a strategy backed by research in the Journal of Natural Science, Biology and Medicine. Treat calorie-laden drinks as occasional indulgences rather than daily staples.

3. Meal Timing Is Working Against You

When and how often you eat can significantly influence weight loss. Skipping meals can lead to overeating later, while constant grazing throughout the day can result in unnoticed calorie overload.

Studies show that front-loading your calories, with a substantial breakfast and lighter evening meals, promotes greater weight loss. Research published in the journal Obesity found that individuals consuming larger breakfasts lost twice the weight compared to those who favored bigger dinners.

How to Fix It: Stick to eating every 3.5 to 4 hours during a 10–12-hour daytime window. This approach stabilizes blood sugar and encourages fat reserves to be used for energy between meals.

4. You’re Overcompensating for Exercise

Exercise is a cornerstone of weight loss, but it’s easy to overestimate the calories burned and indulge in post-workout treats. That post-spin class protein shake or granola bar may negate your calorie deficit if not balanced within your daily intake.

How to Fix It: Plan snacks strategically. If your workout falls within two hours of a meal, skip the extra snack and refuel during your regular meal. If you need a snack, opt for small, protein-rich options like Greek yogurt or a handful of nuts.

5. Water Intake Is Falling Short

Water plays an underrated role in weight loss. Staying hydrated helps control hunger and reduces the temptation to reach for sugary drinks. Dehydration, on the other hand, can be mistaken for hunger, leading to unnecessary snacking.

How to Fix It: Drink 2–6 cups of water daily to satisfy thirst without adding calories. Carry a reusable water bottle as a visual reminder to stay hydrated throughout the day.

What Other Factors Can Hinder Weight Loss

Sitting for long hours, whether at a desk or on the couch, can slow your metabolism and disconnect your body’s natural hunger cues. Incorporating even short bursts of activity, like three 10-minute walks daily, can reignite your metabolism.

Stress often leads to comfort eating, favoring calorie-dense, nutrient-poor foods. Mindfulness practices, such as meditation or journaling, can help address the emotional triggers behind overeating.

Medical conditions, genetics, or hormonal imbalances can also impede weight loss. If your efforts yield no results, consult a healthcare professional for tests or guidance tailored to your needs.

Weight loss isn’t linear, and small, consistent adjustments are more effective than drastic overhauls. By identifying and tackling these hidden barriers, you can set yourself up for lasting success on your health journey.

She came to the hospital because of a cough that would not go away. The cough was eventually found to be nothing serious. But her CT scan revealed something unexpected — a 12 mm nodule in the outer part of her right lung.

She had never smoked. She felt completely well.

Yet that tiny shadow raised a big question: was it an old tuberculosis scar, a harmless growth, or an early lung cancer?

A CT scan can show us that a nodule is there. It cannot always tell us what it is.

This is an increasingly familiar situation. As CT scans have become more widely used, particularly after the COVID-19 pandemic, doctors are finding small lung nodules in people being scanned for entirely different reasons. Most turn out to be benign. Some, however, need closer assessment.

India has another challenge. Tuberculosis and its scars are common, and a lung shadow can sometimes be attributed to TB without tissue confirmation. While treating tuberculosis promptly is important, assuming that every suspicious nodule is TB can occasionally delay the diagnosis of something else, including cancer.

The answer, when appropriate, is to obtain a tissue sample.

Traditionally, a small nodule deep in the lung could be difficult to reach. A needle biopsy through the chest can be effective but carries a risk of a collapsed lung. Conventional bronchoscopy is excellent for the larger airways but becomes more challenging as the target gets smaller and farther towards the edge of the lung. Surgery may sometimes be necessary.

Newer techniques are changing the picture.

Navigation bronchoscopy uses the patient's CT scan to create a three-dimensional map of the airways and guide a thin catheter towards the nodule. Cone Beam CT adds real-time three-dimensional imaging during the procedure, allowing the doctor to check where the instruments are in relation to the lesion before taking the biopsy.

In simple terms, navigation helps us find the way; Cone Beam CT helps us confirm we are there.

The tissue can then be examined immediately where appropriate, helping determine whether the sample is adequate and whether additional material is needed for advanced testing.

Importantly, not every nodule needs a biopsy. Many are best managed through carefully planned follow-up scans. The decision depends on the nodule's size and appearance, previous scans, and the patient's overall risk.

For patients, the message is reassuring: a lung nodule does not mean cancer. But it should not be ignored either.

Keep previous scans. Ask what the likely possibilities are. Understand why your doctor recommends surveillance or biopsy — and make sure the follow-up happens.

Today, advanced bronchoscopy is helping doctors turn a worrying shadow into something much more useful: an answer.

Dry cough and breathing difficulty aren’t always caused by asthma, COPD, or infections. They can also be signs of interstitial lung disease (ILD), a group of lung conditions that can cause inflammation and scarring and, in some cases, progressive loss of lung function.

ILD can go unnoticed in its early stages because its symptoms are often mistaken for more common respiratory conditions. By the time a patient undergoes a CT scan and reaches an ILD clinic, significant lung scarring may have already developed — and some of that damage may be irreversible.

Millions May Be Living With ILD Worldwide

A Global Burden of Disease Study 2023 analysis, published in December 2025, estimated that 4.58 million people were living with ILD and pulmonary sarcoidosis worldwide in 2023, with 112,650 deaths attributed to the conditions that year.

“The true global burden of ILD is higher than currently reported, particularly in underserved populations and low- and middle-income countries,” Prof. Marlies Wijsenbeek-Lourens, Pulmonologist and Head of the Center for Interstitial Lung Diseases and Sarcoidosis at Erasmus University Medical Center, Netherlands, told HealthandMe.

The global expert said most available epidemiological data come from Europe, North America, Japan, South Korea and Australia, where access to specialist care, multidisciplinary diagnosis and high-resolution CT imaging is generally more available.

“As a result, large parts of Africa, South America, South and Southeast Asia remain underrepresented in current estimates. In these regions, more limited access to diagnostic facilities, fewer ILD specialists and under-recognition of disease undoubtedly result in substantial underdiagnosis.”

Even in high-income countries, she added, some patients with ILD likely remain undiagnosed because symptoms such as breathlessness and cough are often attributed to more common conditions.

What Is Interstitial Lung Disease?

ILD is not a single disease but a group of more than 200 lung conditions. The disease affects the interstitium, the tissue surrounding and supporting the lungs’ air sacs, or alveoli. In ILD, this tissue can become inflamed and/or scarred.

As scarring progresses, the lungs can become stiffer, making it harder for them to expand and reducing the efficiency of oxygen transfer. As the disease progresses, the lung shrinks, making it difficult for the patient to breathe.

According to Prof. Marlies, there is a rise in ILD diagnoses due to several factors, such as:

• Better awareness
• More HRCT scans
• Better diagnosis
• Ageing populations
• Autoimmune disease
• Environmental and occupational exposure.

When Should Doctors Suspect ILD?

Some forms of ILD can be treated more effectively when identified early, before permanent lung damage occurs.

“Unfortunately, many patients still reach an ILD specialist late. Breathlessness and cough may initially be treated as asthma, infection or sometimes even tuberculosis. By the time a CT scan is done and the patient reaches an ILD clinic, significant scarring may already have developed,” Dr Asmita Mehta, Professor and Head, Department of Respiratory Medicine at Amrita Institute of Medical Sciences, Kochi, told HealthandMe.

“A dry cough and gradually progressive breathlessness lasting for more than three months, particularly breathlessness while walking or climbing stairs, should raise suspicion of ILD rather than simply being attributed to asthma, infection or ageing,” she added.

Doctors should think of ILD especially when these symptoms do not improve with usual treatment, when fine crackling sounds are heard in the lungs, or when oxygen levels fall during walking.

It is also important to ask about joint pain, skin changes, dry eyes or mouth, and exposure to birds, mould, biomass smoke or occupational dust. Sometimes the clue to ILD is outside the lungs, the expert said.

ILD And COVID-19

Pre-existing ILD was associated with worse outcomes during COVID-19. Now, six years later, some patients who had severe COVID-19 also continue to show persistent lung abnormalities.

“The reassuring part is that not every abnormal CT after COVID means progressive lung fibrosis. In many patients, the lung changes gradually improve or remain stable. Some patients who had very severe COVID, prolonged ICU admission, or required ventilation may be left with persistent scarring and may need longer follow-up,” Dr Asmita said.

What Does ILD Look Like In India?

Common ILD diagnoses seen in India include connective tissue disease-associated ILD (CTD-ILD), hypersensitivity pneumonitis (HP), idiopathic pulmonary fibrosis (IPF), sarcoidosis and idiopathic nonspecific interstitial pneumonia (NSIP).

Dr Asmita said that, apart from idiopathic pulmonary fibrosis, ILD related to autoimmune diseases and environmental exposures is also commonly seen in India. These exposures can include birds, mould, biomass smoke and certain occupations.

Epidemiological reviews estimate the overall prevalence of ILD in India to range between 49.0 and 98.1 per 100,000 people, with an annual crude incidence rate of 10.1 to 20.2 per 100,000 population.

India is also building a larger national evidence base through the ICMR-led Indian Network of Pulmonary Fibrosis (INPF) registry.

Biggest Challenges For ILD Patients In India

• Delayed diagnosis: Symptoms can be mistaken for asthma, infections, or tuberculosis.
• Limited specialist access: ILD specialists and advanced diagnostic facilities are concentrated in larger centres.
• High treatment costs: Medicines, investigations, oxygen, and pulmonary rehabilitation can be expensive.
• Limited transplant access: Lung transplantation remains available only to a limited number of eligible patients.
• Low awareness: Many patients and families are unfamiliar with ILD and its long-term nature.

“We therefore need not only earlier diagnosis, but better awareness, affordable treatment, wider access to ILD specialists and stronger advanced-care and transplant programs,” Dr Asmita said.

Humans and most mammals have two sex chromosomes, X and Y. Females typically have two X chromosomes (XX), while males typically have one X and one Y chromosome (XY). As men age, many of their cells gradually lose the Y chromosome, due to a common genetic change.

Research has shown that cancer incidence and mortality rate are more among men than women. A new study may offer clues as to why.

Researchers from the University of Arizona found that loss of the Y chromosome in men’s tissues could create conditions that allow cancer to develop.

The research, published in JCI Insights, found that Y chromosome loss creates a pre-neoplastic field effect — a hidden zone of genetic vulnerability in normal-appearing tissue that may provide fertile ground for cancer development.

What Did The Study Find?

Previous studies have linked loss of the Y chromosome in blood cells to an increased risk of disease. The new study systematically profiled Y chromosome loss across normal, precancerous and cancerous tissues from 11 major human organs.

“We were able to show that the loss of the Y chromosome is found in normal-appearing tissues adjacent to a tumor,” said physician-scientist Dr. Dan Theodorescu of the University of Arizona Cancer Center.

“That finding is what makes this discovery so exciting. It suggests we may be looking at one of the earliest signposts of cancer forming.”

The team analyzed 1,000 tissue samples from 405 men, using an automated fluorescent imaging system to examine more than 4.3 million individual cell nuclei and measure the ratio of Y to X chromosomes.

In one part of the study, researchers created detailed maps of bladder tissue removed during cancer surgery.

The maps showed that Y chromosome loss increased as tissue progressed from normal tissue to early abnormal cells and then to cancer.

Y chromosome loss in normal-appearing tissue was highest in samples from colon, rectal, esophageal, pancreatic and lung cancers.

“We are now thinking of this as a gradient, similar to a hillside that slowly gets steeper,” Theodorescu said. “The closer the tissue is to a cancer, the more Y chromosome loss we see. That gradient could one day help doctors suspect trouble in biopsies that miss a smaller cancer.”

Theodorescu’s previous research examined how loss of the Y chromosome in cancer cells can help them evade the immune system. This may help explain why Y chromosome loss has been associated with higher mortality from certain carcinomas.

What Does The Y Chromosome Do?

The Y chromosome spans more than 59 million DNA base pairs and accounts for almost 2% of the DNA in human cells. It contains roughly 70 to 200 genes involved in protein production.

The chromosome contains genes that play important roles in male sex development and fertility, including sperm production.

Beyond reproduction, research suggests that the Y chromosome can influence immune and inflammatory responses in men, potentially affecting susceptibility to certain diseases.

Cancer Risk In Men

Globally, cancer is diagnosed more often in men than in women, with men having roughly a 25% higher incidence rate. Men also account for a greater share of cancer deaths worldwide.

Some of the most common cancers affecting men include prostate, lung, colorectal and skin cancers. Early detection and appropriate screening can improve the chances of successful treatment for several types of cancer.
