Just a few days into the new year is a good time to look back at the New Year's resolution, for health, diet and fitness! A 75-ditness challenge may not be the first thing that comes to your mind. However, this has gained a massive traction on TikTok. It is called the "75 Hard" challenge, where participants also document their progress. The challenge includes strict rules to comply with. These include: adhering to a healthy diet with no cheat meals or alcohol, completing two 45-minute workouts daily (one outdoors), drinking over three liters of water, and reading 10 pages of a non-fiction book each day.

While this might seem like a straightforward regime, experts suggest that for some, a more relaxed version may help them better.

What the participants feel?

As reported in BBC, Devamsha Gunput, 29, who successfully completed the 75 Hard challenge while juggling a full-time job as a digital consultant in Edinburgh described it as a "tough but transformative journey". One of the biggest challenges she faced was setting boundaries with her South Asian family to maintain her strict diet.

Living in Edinburgh’s dark, wet, and cold weather made outdoor workouts particularly difficult. Despite these hurdles, Devamsha noticed lasting benefits, including more consistent exercise habits, improved reading routines, and a better relationship with food.

The origin of this challenge

The challenge was originally created in 2019 by author and podcaster Andy Frisella to foster mental toughness. While not a certified personal trainer or doctor, Frisella designed the program based on his personal experiences, emphasizing discipline rather than weight loss or specific physical outcomes.

Initial challenges

For Sophie Deakins, 27, who completed the challenge while managing a cinema in London, 75 Hard was a way to address her struggles with consistency and discipline. She eliminated sweets, opting instead for natural sugars from fruit and honey, and tracked her diet and water intake meticulously.

Sophie found the first few weeks challenging as she adjusted to new habits, particularly when socializing, as it often revolved around dining out and drinking. By being open about her goals, she was able to navigate these situations without succumbing to temptation.

Post-challenge, Sophie continued some habits, like avoiding unnecessary coffee shop purchases and limiting eating out, which not only improved her health but also saved her money. Most importantly, she experienced a significant mindset shift, overcoming self-doubt and excuses about time.

Balancing the Pros and Cons

While many find 75 Hard rewarding, it’s not suitable for everyone. Strength and conditioning expert and gym coaches advise considering the significant time commitment required for the workouts, reading, and other tasks. They suggest adopting simpler elements like daily movement and drinking more water without feeling overwhelmed.

Motivation is another concern. The pressure to transform one’s life at the start of the year can be counterproductive. Experts recommend setting achievable goals that add joy and value to daily life rather than creating stress.

What does not work out?

The 75 Hard challenge has not been clinically studied, nor has it been made after considering an average person's ability to cope with such changes so quickly. It is personally designed by Frisella, whose strength may not match others. This is what is making its long-term benefits unclear. Healthcare providers, doctors, and other experts point out that a more basic routine, such as regular exercise and a balanced diet, might achieve similar results without the extreme demands.

Ultimately, while 75 Hard can help build discipline and mental toughness, it’s essential to tailor health and fitness goals to your needs. For reliable guidance, the NHS Live Well website offers comprehensive advice on diet, exercise, and mental well-being.

Cortisol is one of the body's most powerful hormones, which is essential for survival, yet capable of quietly undermining health when chronically elevated. The line between beneficial training stress and harmful overload is thinner than most athletes realize, and the body's early warning signals are easy to dismiss.

Understanding how cortisol responds to exercise and when that response tips from adaptive to destructive is foundational to training smarter, recovering better, and protecting long-term health.

Why Cortisol Matters

Cortisol is a vital, life-sustaining hormone essential for survival and adaptation. During physical exertion, it ensures the immediate mobilization of energy by triggering the breakdown of stored carbohydrates and fats (gluconeogenesis and lipolysis) to fuel working muscles. Additionally, it maintains vascular integrity and acts as a powerful anti-inflammatory agent, safely modulating the immune system to protect the body against extreme inflammation caused by exercise-induced tissue damage.

When Exercise Becomes Stress

Exercise is naturally an acute stressor, but it transitions into a harmful chronic stress when training loads exceed the body's ability to recover. High-intensity, prolonged aerobic exercise or extreme high-volume resistance training, combined with inadequate rest, sleep disruption, and external stressors, keeps the hypothalamic-pituitary-adrenal (HPA) axis constantly activated. When the natural 24-hour cycle of cortisol is disrupted and if the body does not get a long enough period of low cortisol exposure, exercise transitions from a positive adaptation (eustress) into destructive physiological strain.

Beyond Stress: How Excess Cortisol Reshapes the Body

The physical remodeling that chronic cortisol causes is profound and operates at the molecular level. Protein degradation occurs through activation of the ubiquitin–proteasome system. Cortisol further suppresses anabolic pathways by inhibiting mTOR signaling and reducing insulin-like growth factor 1 activity, leading to a sustained decrease in protein synthesis.

Visceral fat cells, the deep abdominal fat surrounding internal organs, have more cortisol receptors than fat cells elsewhere in the body. When cortisol levels remain elevated, these receptors essentially attract and store more fat in the midsection.

While Ozempic or Wegovy offer weight loss benefits, a significant caveat is the risk of regaining the kilos. This is not only a waste of money and effort but may also affect overall health.

About 70 per cent of people who stop these drugs eventually regain much of the weight they lost, often within 18 months.

Now, US researchers have developed a new minimally invasive procedure that resets the gut, and in early trials, has shown potential to help people maintain weight loss after stopping these popular drugs, which contain semaglutide — a GLP-1 receptor agonist — as the main ingredient.

Presenting the research at the Digestive Disease Week (DDW) 2026, the team noted that the procedure works by renewing the lining of the upper small intestine. It potentially “resets” metabolism and helps preserve the benefits of weight loss.

The technique is called duodenal mucosal resurfacing. In a clinical trial, people who underwent the procedure regained far less weight compared to others after discontinuing the medication.

"Finding a treatment that allows patients to stop these medications without weight regain or loss of metabolic benefit is a huge unmet need," said lead author Shelby Sullivan, director of the Endoscopic Bariatric and Metabolic Program at Dartmouth Health Weight Center and professor of medicine.

"These findings indicate that this minimally invasive procedure may provide lasting weight-loss maintenance."

How The Procedure Works

Duodenal mucosal resurfacing is an investigational endoscopic treatment that uses controlled heat to remove damaged tissue from the inner lining of the duodenum, the first section of the small intestine just below the stomach.

This process, which ablates the unhealthy mucosal layer, encourages the growth of new, healthier tissue.

The treatment targets the small intestine, where many of the hormones affected by GLP-1 drugs are produced. Over time, diets high in fat and sugar can alter the lining of the duodenum, changing how the body processes food and regulates hormones. These changes can contribute to insulin resistance and metabolic disease.

By restoring a healthier mucosal layer, the procedure aims to reset the body's response to food, helping to stabilize metabolism at a lower body weight after stopping medications like Ozempic.

How Was The Study Conducted?

The findings are based on an early group of participants with six months of follow-up data. Among 45 people in this cohort, 29 received the resurfacing treatment while 16 underwent a sham procedure.

All participants had previously lost at least 15 per cent of their body weight using tirzepatide before stopping the drug. On average, patients lost about 40 pounds while on GLP-1 therapy. Six months after discontinuing the medication, those in the control group regained significantly more weight. Participants who received the sham procedure regained about 40 per cent more weight than those who underwent the actual treatment.

In addition, patients who had more extensive resurfacing regained only about 7 pounds and kept more than 80 per cent of their weight loss.

By comparison, the control group regained roughly twice as much. The gap between the two groups continued to widen from one to six months after the procedure, suggesting the benefits may persist and even strengthen over time.

"What's particularly encouraging is that the benefit appears to increase over time rather than fade, and that it behaves like a drug in terms of dose response," Dr. Sullivan said. "That gives us confidence that we're targeting the right biology."

No serious complications were reported from either the device or the procedure. Recovery is relatively quick, with most patients returning to normal activities within about a day.

At a time when most people follow a sedentary lifestyle, exercise is nothing short of medicine. However, for someone who is lazy, workouts can take a good deal of effort — but what if we told you that there are some simple exercises that will not take much of your time and can be done easily while lying flat on your back? According to experts, without having to lift a finger, you can get in shape.

Best workouts to do in bed

Researchers at Teikyo University in Tokyo, Japan, found that people can improve their agility, balance, and flexibility by engaging in a simple exercise programme that involves three exercises. These exercises engage the leg muscles and core in an easy and safe position. Writing in the journal PLOS One, the study authors compared the routine to Pilates, and experts said that it can help prevent falls and support early rehabilitation.

Adults are recommended to do two and a half hours of exercise each week, but about a third of people do not meet this target. In this study, 39 healthy men and women in their 20s, with optimal flexibility, balance, speed, and strength, were involved. They were all tested before and after a two-week regimen of lying down and working out. The exercises they were asked to perform were:

1. Tense the abs for five seconds while pressing them with the fingers—repeat three times
2. Lifting the hips off the ground to form a bridge pose, keeping the feet flat on the ground—hold for five seconds and repeat 10 times
3. Bending one leg at the knee and holding the ankle at 90 degrees, clenching and unclenching the toes; ensure that the heel slides along the floor towards and away from the body—repeat three times with each leg

Fifteen days later, participants showed significant improvement in standing balance, flexibility, and agility. However, they did not show improvement in raw muscle strength, jumping ability, or grip strength tests. Scientists said that these improvements were likely due to better muscle control rather than increased muscle mass. They also noted that no prior research has shown an exercise programme that is short and performed in a supine position to be effective in this way. However, this routine, which showed improvements in flexibility, agility, balance, and stability, shows promise. It could also be helpful for rehabilitation in older adults.

What is exercise snacking?

Exercise snacking refers to an approach created for people who struggle to find time for long gym sessions. Instead of spending hours at the gym, people can perform small bursts of exercise throughout the day. These sessions are an effective way to stay active without needing to block out time specifically for fitness. They can be spread across the day, with mini workouts lasting five to 10 minutes and repeated multiple times. The benefits are significant when practised consistently, especially for those with desk jobs or those suffering from diabetes, hypertension, high cholesterol, or even depression.
