A cardiologist has explained that losing just 5% of body weight in your 50s can significantly improve cardiovascular health, based on new research showing comparable heart-health indicators to those who maintained a healthy weight throughout adulthood.
Study Findings on Midlife Weight Loss
Researchers at University College London examined data from more than 6,000 individuals born in Britain in 1958, tracking their weight and wellbeing over several decades. Approximately one in four participants maintained a healthy weight for most of their adult lives, while around 6% shed at least 5% of their body weight by age 50 and kept it off until 55.
By age 62, this latter group displayed blood pressure, cholesterol, and inflammatory markers similar to those who had stayed at a healthy weight throughout adulthood. In contrast, individuals who gained weight into or within the obesity range experienced less favourable cardiovascular and metabolic health profiles.
Expert Advice on Sustainable Changes
Dr Francesco Lo Monaco, preventive cardiologist and founder of the National Heart Clinic, said the findings deliver an uplifting message for those seeking to improve their wellbeing in middle age. He stated: "Your 50s are not too late to make meaningful changes. You cannot rewrite your health history, but you can influence what happens next."
He added: "For someone who is overweight, even a modest, sustainable reduction can be a worthwhile goal to discuss with a healthcare professional. The important thing is to avoid extreme diets and focus on changes you can maintain."
Practical Tips for Weight Management
Dr Lo Monaco advised focusing on meal composition rather than simply eating less. He recommended building meals around protein sources like eggs, fish, beans, lentils, and plain yoghurt, alongside fibre-rich carbohydrates such as oats, wholegrains, and pulses. Swapping refined carbohydrates for beans or lentils, adding vegetables to meals, and choosing whole fruit over juice can help increase fullness and improve nutrition.
He also suggested reviewing small extras like sugary drinks, alcohol, regular snacks, and generous portions of oils, dressings, or sauces. Rather than overhauling everything at once, he advised identifying one or two habits contributing most to intake and addressing those first.
Preserving Muscle and Long-Term Health
Dr Lo Monaco cautioned against focusing solely on the scales: "Weight loss should not come at the expense of muscle. As we get older, maintaining strength becomes increasingly important, so combine appropriate dietary changes with regular activity and resistance exercises suited to your ability. Track progress over weeks rather than reacting to daily fluctuations and speak to your healthcare professional if you are unsure what a healthy target would be for you."
The researchers emphasised the study was observational, so it cannot prove weight loss directly caused the health differences, nor does it suggest everyone needs to lose weight. However, Dr Lo Monaco noted the findings are encouraging, suggesting midlife remains a chance to enhance wellbeing through modest, achievable changes.
