When diet and exercise aren’t enough: Why seeing a GP for weight loss makes a difference
Maintaining a healthy weight is one of the most important steps an individual can take to support their long-term health. However, weight loss is not always as simple as eating less and moving more. While diet and exercise are essential foundations, they may not be sufficient for everyone. In this article, a consultant GP explains why speaking with a GP can be the key to unlocking solutions for many patients struggling with weight.
Why a healthy weight matters
Carrying excess weight significantly increases the risk of developing a range of serious health conditions. These include type 2 diabetes, high blood pressure, heart disease, certain cancers, and sleep apnoea. Beyond physical health, there’s a strong link between being overweight and mental health concerns, such as low self-esteem, depression, and anxiety. Often, these issues can form a cycle—poor mental health can make it more difficult to maintain healthy habits, and struggling with weight can worsen mood and motivation.
Maintaining a healthy weight isn't only about appearance; it’s about quality of life, long-term well-being, and reducing the risk of preventable disease.
Why diet and exercise might not be enough
For many, losing weight through lifestyle changes alone – such as exercise and diet – proves to be extremely difficult. Biological, psychological, and environmental factors all play a role in body weight regulation. Hormones, genetics, past weight-loss attempts, and even medications can make it harder to lose weight and keep it off. These are important to consider, especially as they are out of the patient’s control.
It’s common for patients to feel disheartened after months of calorie counting, meal prepping, and gym sessions with little to show for it. Unfortunately, the body often responds to weight loss by slowing metabolism and increasing hunger signals, making further weight loss even more challenging. This is not a failure of willpower, but it is the body doing what it’s evolved to do: resist weight loss.
When to see a GP about weight loss
It’s time to speak to a GP if weight is starting to impact your physical health, mental wellbeing, or everyday life. This may include struggling with mobility, feeling breathless with light activity, or noticing symptoms of associated conditions like joint pain, high blood pressure, or poor sleep.
Patients who have tried diet and exercise consistently for several months without success, or who regain weight quickly after losing it, should also consider a consultation. Likewise, if emotional eating, stress, or mental health is contributing to weight gain, it’s important to seek help.
No concern is too small, and early intervention can prevent more serious complications down the line.
How a GP can help with weight loss
As frontline health professionals, GPs are well-placed to assess weight-related concerns and tailor advice to individual needs. This begins with a thorough review of medical history, lifestyle, and any underlying conditions that might be contributing to weight gain.
A GP can provide realistic, personalised guidance, help set achievable goals, and refer patients to services such as weight management programmes or dietitians. In some cases, psychological support such as counselling or CBT may be offered to help address emotional eating habits.
Importantly, GPs can also discuss medically supported options, such as weight-loss medications, which are now more effective and widely available than ever before. These treatments are not for everyone, but for suitable patients, they can make a meaningful difference.
