Losing weight is often seen as an entrance for better health, but new research suggests that for individuals with heart disease, significant weight ups and downs – whether benefits or disadvantages – can cause serious risk. A groundbreaking study by Anglia Ruskin University (ARU) published in BMJ Journal Heart highlights how changes in extreme weight, which affects mortality in thick individuals with heart conditions.
Amazing conclusion
The study analyzed data from 8,297 UK participants enrolled in the UK Biobank Studies over a period of 14 years. Researchers tracked their weight changes and got dangerous results:
- Participants who received more than 10 kg increased the risk of heart death threefold and almost double the death rate compared to stable weight people.
- Surprisingly, people who lose more than 10 kg, also faced 54% more risk of death for any reason.
- High BMI, smoking and previous alcohol consumption were linked to the increasing possibility of significant weight gain, especially among young individuals.
Why does weighing ups and downs matters?
While it is recommended to lose weight for obese people, this study suggested that rapid or extreme changes in body weight can be harmful, especially for individuals diagnosed in advance. Researchers believe that heavy weight loss can lead to muscle deficiency, nutritional deficiency or metabolic stress, which can negatively affect heart health.

Professor Barbara Pierceonak, a co-author of the study, insisted, “maintaining a stable weight, even within a thick range, seems important to reduce the risk of mortality in heart patients.”
The rate of obesity is growing at a dangerous rate and in England alone, the percentage of obese individuals has almost doubled by 15% in 1993, to 29% in 2022, with more than 35 people considered to be overweight or obese. This growing epidemic estimates that NHS £ 6.5 billion annually, adding tension to public health systems, while globally, obesity is expected to affect more than half of all adults by 2050.
