Just 150 minutes of exercise a week could reverse Prediabetes
On the other hand, Prediabetes usually does not cause any symptoms, and only a blood test can confirm the same. The good news is that in most cases, Prediabetes is highly reversible, through the right lifestyle changes, diet control and most importantly, exercise. Yes, new research says that just 150 minutes of exercise per week can significantly reverse prediabetes... Let's see how..
The study
New research published in Cardiovascular Diabetology – Endocrinology Reports brings encouraging news: just 150 minutes of exercise per week can significantly reverse prediabetes and restore normal blood sugar levels.
What is Prediabetes level
Prediabetes is a condition where blood sugar levels are higher than normal but not high enough to be diabetes. It is usually identified by:
Fasting blood glucose between 100 and 125 mg/dL
Glycated hemoglobin (HbA1c) between 5.7% and 6.4%
Oral glucose tolerance test results between 140 and 199 mg/dL after a glucose load
If left unchecked, prediabetes often progresses to type 2 diabetes rather quickly, a chronic (and mostly irreversible) disease that can cause heart disease, kidney failure, nerve damage, and other serious complications.
The Study
The recent study analyzed data from Colombian adults enrolled in a cardiovascular risk program between 2019 and 2023. Participants began with a median HbA1c of 5.9%, indicating borderline blood sugar control. Researchers found that those who engaged in more than 150 minutes of physical activity per week were four times more likely to reverse prediabetes, and return to normal glucose levels compared to less active individuals.
This finding highlights that even a moderate amount of exercise—just over two hours a week—can make a huge difference in preventing diabetes.
How does it help
Exercise improves the body's ability to use insulin effectively, which helps control blood sugar levels. It also:
Increases glucose uptake by muscles
Enhances insulin sensitivity
Helps reduce body weight and body fat
Lowers blood pressure and cholesterol levels
Reduces inflammation and stress hormones
Which exercises should one do
A review of 24 studies involving nearly 2,000 prediabetic patients, found that combining moderate-intensity aerobic exercise with low-to-moderate resistance training, offers the best results for sugar control and weight loss.
Aerobic (or cardio) exercises include brisk walking, jogging, cycling, swimming, or dancing, while resistance training involves weight lifting or bodyweight exercises like squats and push-ups.
How much exercise do you need
The study confirms that 150 minutes per week of moderate physical activity is a practical and achievable target. This can be broken down into:
30 minutes a day, 5 days a week, or
Shorter sessions spread throughout the week
Additional benefits
Exercise also helps reduce other risk factors associated with diabetes, such as:
Lowering total cholesterol and LDL ('bad' cholesterol)
Reducing body mass index (BMI) and body weight
Improving blood pressure control
Enhancing cardiovascular fitness and muscle strength
Who Benefits the Most
The benefits of exercise are especially significant for:
Older adults (over 60 years), who showed greater improvements in fasting blood glucose
Those with higher body mass index and HbA1c levels
People who combine exercise with healthy diet and weight management

150 Mins Of Exercise A Week Could Reverse Pre-Diabetes Study Claims
A new study featured in Cardiovascular Diabetology – Endocrinology Reports offers promising insights: engaging in just 150 minutes of weekly exercise can greatly improve blood sugar levels and even reverse prediabetes. The research, which examined data from Colombian adults involved in a cardiovascular risk program from 2019 to 2023, revealed that participants initially had a median HbA1c of 5.9%, a marker of borderline glucose control. Notably, those who exercised for more than 150 minutes each week were found to be four times more likely to restore normal blood sugar levels and reverse their prediabetic condition compared to those who were less physically active. Engaging in at least 150 minutes of moderate-intensity exercise per week can significantly help reverse pre-diabetes and improve heart health. Keep reading as we discuss how exercise can benefit your heart health and reverse pre-diabetes. 10 ways 150 minutes of exercise a week could reverse pre-diabetes 1. Improves insulin sensitivity Exercise makes muscle cells more receptive to insulin, meaning glucose can be absorbed from the bloodstream more efficiently. Over time, this can restore healthy blood sugar regulation and reduce insulin resistance, the key driver of pre-diabetes. 2. Lowers blood glucose levels naturally Physical activity helps lower blood sugar both during and after workouts by prompting muscles to use glucose as fuel. Regular sessions can maintain this effect long-term, keeping blood sugar within a healthy range. 3. Reduces visceral fat Excess fat around the abdomen is linked to insulin resistance and inflammation. Exercise helps burn visceral fat, decreasing inflammation and improving metabolic function, which are vital for reversing pre-diabetes. 4. Boosts weight loss and maintenance Even modest weight loss (5–7% of body weight) through consistent exercise can significantly reduce the risk of type 2 diabetes. Exercise supports fat loss while preserving lean muscle, aiding long-term weight management. 5. Enhances muscle mass and glucose uptake More muscle means greater glucose storage capacity. Resistance training as part of your 150-minute routine builds lean mass that actively absorbs blood sugar, reducing strain on insulin production. 6. Lowers inflammation levels Chronic low-grade inflammation contributes to insulin resistance. Regular workouts reduce pro-inflammatory markers and improve immune function, helping reset the body's metabolic balance. 7. Regulates blood pressure and lipid levels Many with pre-diabetes also have high blood pressure or abnormal cholesterol. Exercise improves cardiovascular markers, lowering triglycerides and LDL (bad cholesterol), while increasing HDL (good cholesterol). 8. Improves sleep quality and stress management Poor sleep and high stress elevate cortisol, which can spike blood sugar levels. Exercise promotes better sleep patterns and helps manage stress hormones, supporting metabolic recovery and regulation. 9. Builds healthy habits and routine Dedicating 150 minutes a week to exercise often sparks broader lifestyle changes, such as improved diet, hydration, and mindfulness, all of which support reversal of pre-diabetes and improved heart health. 10. Reduces risk of progression to type 2 diabetes According to studies, lifestyle interventions like regular exercise reduce the risk of progressing from pre-diabetes to type 2 diabetes by over 50%. This weekly commitment becomes a powerful long-term investment in metabolic health. Committing just 150 minutes a week to exercise can be life-changing for someone with pre-diabetes. It not only helps reverse early metabolic dysfunctions but also enhances heart health, reduces stress, and strengthens the entire body. The best part? It's sustainable, cost-free, and adaptable to any lifestyle, making it one of the most effective tools for reclaiming health naturally.

Just 150 minutes of exercise a week could reverse Prediabetes
Prediabetes is a condition where blood sugar levels are higher than normal, but not high enough to be diagnosed as type 2 diabetes (yet). For most people, it is a warning sign that without lifestyle changes, you are at increased risk of developing type 2 diabetes, heart disease, and stroke. On the other hand, Prediabetes usually does not cause any symptoms, and only a blood test can confirm the same. The good news is that in most cases, Prediabetes is highly reversible, through the right lifestyle changes, diet control and most importantly, exercise.

This CT scan belongs to ‘a 73 year old woman in whom doctors discovered a 30 year old calcified fetus' aka stone baby
Have you heard of the rare medical phenomenon known as a lithopedion, where a fetus dies in the womb and becomes calcified over time? On June 25, X account Non Aesthetic Things, which has 4.8 million followers on the platform, shared a 'CT scan of a calcified fetus' and said that it had been present for approximately 30 years. Also read | Rare disease: Causes, signs and symptoms, treatment, who should get tested Ever heard of a calcified fetus? This is what it could look like. (X/ Non Aesthetic Things) Non Aesthetic Things' tweet alongside the CT scan read, 'This CT scan belongs to a 73-year-old woman in whom doctors discovered a 30-year-old calcified fetus.' The presence of a calcified fetus for 30 years is a rare and fascinating phenomenon that can provide valuable insights for medical professionals. Unsurprisingly, social media reactions to the rare medical case was a mix of shock, fascination, and curiosity. Social media reacts to 'stone baby' Reacting to Non Aesthetic Things tweet, an X user asked, 'Really?? Fake?? Is it possible for a 73-year-old woman, who has never had a medical service, including a CT scan, to realise she had a calcified fetus in her? Impossible!!!' Someone also tweeted, 'How did she carry that fetus for so long… didn't she feel discomfort?' Another person responded with: 'Context: CT scan shows the moment doctors found a 'stone baby' inside the womb of a 73-year-old woman from Algeria. The stone baby, also known as a lithopedion, is created when a pregnancy forms in the abdomen rather than in the uterus. When the pregnancy fails, the body lacks a mechanism to naturally expel it. Consequently, the body undergoes a process of calcification, essentially turning the fetus into a 'stone,' utilising the immune process designed to protect against any foreign objects detected in a person's system.' Is this even possible? Interestingly, back in 2013, ABC News reported that an 82-year-old Colombian woman was stunned when she went to the doctor for pelvic pain and was told the pain was caused by a 40-year-old 'stone' fetus. Dr Kim Garcsi of University Hospitals Case Medical Center in Cleveland, was quoted as saying the 'condition was so rare it has only been recorded approximately 300 times in medical literature'. Dr Garcsi explained that lithopedion is created when a pregnancy forms in the abdomen rather than in the uterus. When the pregnancy ultimately fails, usually because the fetus does not have enough blood supply, there is no way for the body to expel the fetus. As a result, the body turns the fetus to stone, using the same immune process that protects the body from any foreign object detected in a person's system. Dr Garcsi said it may seem odd, but that the process is used constantly in the body to stay healthy.
