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.

Knee replacement surgery has witnessed remarkable advancements over the past few years. Traditionally, total knee replacement was performed as a uniform procedure ("one procedure fits all"), where the entire knee joint was replaced regardless of the extent or location of damage.

However, with the evolution of modern orthopedics, the focus has shifted towards precision and personalized treatment. In this direction, an A La Carte or Modular approach towards patients who need knee Replacement has emerged, which customizes or personalizes the surgery according to the patient’s specific condition.

Understanding The “à la carte” Concept

The term “à la carte” refers to selecting individual items from a menu. In knee replacement surgery, it means replacing only the damaged portion of the joint instead of the entire knee.

The knee is anatomically divided into three compartments:

• Medial compartment (inner side)
• Lateral compartment (outer side)
• Patellofemoral compartment (front portion involving the kneecap)

In many patients suffering from osteoarthritis, the disease affects only one or two of these compartments—most commonly the medial compartment. In such cases, replacing the entire knee may not be necessary. Modular implants allow surgeons to selectively treat the affected area while preserving healthy bone and ligaments.

The à la carte technique helps preserve the natural structure of the knee while effectively treating only the damaged portion, resulting in better and more natural functional outcomes for patients.

However, this approach is not suitable for all patients. It is generally not recommended in inflammatory conditions such as rheumatoid arthritis.

How It Differs From Total Knee Replacement

In Total Knee Replacement (TKR), all three compartments of the knee are replaced, making it an effective solution for advanced and widespread arthritis.

In contrast, Modular Knee Replacement offers a more targeted approach:

• Replacement of a single compartment (Partial Knee Replacement)
• Replacement of two compartments (e.g., medial + patellofemoral)

This selective treatment helps maintain the knee’s natural structure and function.

Advantages Of The Modular Approach

For carefully selected patients, this technique offers several important benefits:

• More natural knee function: Preservation of ligaments and bone provides a more natural feel.
• Faster recovery: Less invasive surgery leads to quicker rehabilitation.
• Reduced pain and blood loss: Minimal surgical trauma results in less discomfort.
• Improved mobility: Patients often achieve a better range of motion.
• Enhanced lifestyle comfort: Activities like sitting cross-legged or squatting may be easier and can be done unrestricted compared to total knee replacement.

Who Is the Ideal Candidate?

Not every patient is suitable for this procedure. Proper patient selection is one of the most critical factors in ensuring the success of this procedure. Ideal candidates typically include people:

• Having arthritis limited to one or two compartments
• Having stable knee ligaments
• Who do not have a severe deformity in the knee

Long-Term Outcomes

When performed in the right patient, modular knee replacement delivers excellent long-term outcomes (90 to 95 per cent survivorship for 15 years). Its success largely depends on accurate patient selection and flawless surgical expertise.

In some cases, if arthritis progresses in the remaining compartments over time, conversion to total knee replacement can still be done. However, this is relatively uncommon when proper indications are followed.

Role Of Robotic Technology

Robotic-assisted surgery has further enhanced the precision of this technique. It enables:

• Millimeter-level accuracy
• Precise implant positioning
• Restoration of patient-specific knee alignment

Conclusion

Ala Carte or Modular Knee Replacement represents a significant shift toward personalized orthopaedic care. Instead of a "one-size-fits-all " approach, surgeons can now tailor treatment based on the patient’s anatomy and disease pattern.

For many patients, this means less invasive surgery, faster recovery, improved function, and a more natural-feeling knee. Individuals experiencing persistent knee pain are advised to consult an orthopaedic specialist early to determine the most appropriate treatment option.

Beyond lung cancers, air pollution fine particulate matter (PM2.5) is increasing mortality for breast as well as liver cancers, according to a global study led by the Union for International Cancer Control (UICC), including researchers from the Indian Council of Medical Research (ICMR).

The important study showed that long-term exposure to PM2.5 increases the overall risk of developing cancer and the chances of dying from it compared with those living in cleaner environments.

For every 10 micrograms per cubic meter (µg/m³) increase in PM2.5 exposure, the overall risk of cancers increases by more than 11 per cent. At the same time, the risk of death also increases by more than 12 per cent for every 10 µg/m³ increase in PM2.5 exposure.

The researchers argued that while other common risk factors like tobacco and alcohol are being targeted with notable progress, air pollution is silently eroding the gains being made.

“We have made huge strides in reducing deaths from cancer, but polluted air is silently undermining that progress. It is a risk people cannot opt out of, and one that disproportionately affects women, children, and people living in poverty,” Cary Adams, CEO, UICC.

“The cancer community continues to make progress in addressing other major risk factors, including tobacco use, alcohol consumption, and viral, bacterial, or parasitic infections such as HPV and HBV that cause cervical and liver cancers. It is increasingly clear that air pollution must also be recognized as a major and preventable factor that increases the risk of developing cancer and of dying from the disease,” added Dr Elisabete Weiderpass, Director, IARC.

Risks of PM2.5: Beyond Lung Cancer

The study, based on data from 42 meta-analyses and systematic reviews published between 2019 and 2024, showed significantly strong associations for liver, colorectal, and breast cancers.

As per recent data from the International Agency for Research on Cancer (IARC), PM₂.₅ exposure contributes to 434,000 lung cancers per year, accounting for more than a quarter of preventable lung cancers in women and nearly one in six in men.

In addition to lung cancer risk, the study noted that the rising levels of PM2.5 are associated with

• a 32 per cent higher incidence of liver cancer
• an 18 per cent increase in the odds of developing colorectal cancer.

• a 12 per cent higher overall risk of dying from cancer,
• a 20 per cent higher risk of death from breast cancer,
• a 14 per cent from liver cancer,
• a 12 per cent from lung cancer.

Who Is At A Higher Risk

According to the researchers, people living in low- and middle-income countries bear the greatest overall burden. These countries frequently lack the resources to reduce pollution at source or to provide timely access to cancer prevention, diagnosis, and treatment.

The challenge is compounded by the projected rise in global cancer cases, expected to increase from 20 million in 2022 to 35 million by 2050. People at risk include:

• Women and children, particularly in settings where solid fuels are used for cooking and heating.
• Women exposed to household air pollution face a 69 per cent higher risk of lung cancer, alongside increased risks of cervical cancer.
• Outdoor workers and communities living near industrial facilities are also at heightened risk, with exposure often concentrated in economically deprived areas.

What Actions Are Required?

The researchers underscored that the evidence presented in the report is already sufficient to justify decisive action to reduce exposure to polluted air. They called upon policymakers to make required changes across energy, transport, industry, and urban planning to reduce the risk of cancer from air pollution.

The study urged the need for properly implementing effective interventions that are well-established. These include:

• Stronger emissions standards and enforcing the WHO air quality Standards
• A transition to clean energy and clean cooking
• Improved urban design by investing more in green infrastructure
• Expanded air-quality monitoring in High-Risk Areas
• Update cancer control plans.

During the summer, it is important to stay hydrated, but for kidney patients, excessive intake of fluids is just as dangerous as not drinking enough. Most people are encouraged to drink extra fluids during hot weather; however, patients with chronic kidney disease (CKD) and those on dialysis must exercise greater control over their daily hydration and fluid intake because their bodies cannot effectively excrete excess fluids, leading to potential complications.

What is overhydration?

Dr Anupam Roy, Additional Director – Nephrology and Kidney Transplant at Aakash Healthcare Multi-Specialty Hospital, Dwarka, said, “Overhydration occurs when the body retains more fluid than it is able to eliminate. For kidney patients, overhydration typically leads to fluid overload as a result of excessive fluid accumulation in the body. Early signs of fluid overload may include swelling in the feet, ankles, and/or face. If not treated, fluid may continue to build up and cause the lungs to fill with fluid, resulting in shortness of breath and difficulty lying down. If left untreated, gaseous exchange in the lungs will be impaired, and the patient will require immediate medical treatment for pulmonary oedema (a life-threatening complication).”

What happens when you are overhydrated?

The effect of excess fluid on the heart and blood pressure is considered a significant concern. Excess fluid results in additional strain on the cardiovascular system, leading to high blood pressure. This extra workload may also increase the risk of serious complications (e.g., heart failure) for individuals who already have hypertension or heart disease. Dialysis patients are at particular risk of developing complications since they rely on regularly scheduled treatments to remove excess fluid. Excessive fluid consumption between dialysis sessions may complicate and increase the discomfort associated with removing excess fluid during dialysis.

How does overhydration affect kidney disease patients?

Overhydration may also cause an imbalance in electrolytes, such as sodium. Consuming a large amount of water without adequate intake of electrolytes could dilute sodium in the bloodstream, resulting in hyponatraemia. Symptoms of hyponatremia vary from mild (nausea and headaches) to severe (confusion, seizures, and, in extreme cases, coma). This condition can potentially be life-threatening for kidney disease patients, who often have difficulty maintaining an optimal balance of electrolytes.

Many people forget that they can obtain fluids from certain foods and drinks, such as soup, yogurt, watermelon, and tea or juice. In the summertime, people tend to consume these types of foods and drinks more often, which can cause them to exceed the recommended daily fluid intake. Many also believe that drinking extra water will flush toxins out of their system; however, when the kidneys are not functioning properly, excess fluids can be difficult to remove from the body.

How much water should kidney patients drink?

Dr Roy said that proper hydration for someone with kidney disease needs to be planned carefully. The amount of fluid a person can consume depends on their stage of kidney disease, urine output, and whether they are on dialysis. Some simple strategies can help maintain proper hydration: use small cups for drinks, consume fluids throughout the day rather than all at once, avoid foods high in salt (as these increase thirst), and track daily fluid intake.

The main reason for drinking fluids is to ensure the right amount is consumed; therefore, the most important aspect of hydration is maintaining balance. Maintaining this balance can help prevent complications and allow individuals to remain as healthy as possible. When kidney patients understand their hydration needs and receive proper guidance during the summer, they can avoid causing further harm by placing additional strain on their bodies.
