Weight loss is a topic that generates numerous questions and often conflicting advice. This article aims to address some of the most frequently asked questions about weight loss, providing clear, science-based answers.
What’s the healthiest way to lose weight?
The healthiest approach to weight loss involves a combination of balanced nutrition and regular physical activity. The NHS recommends a steady weight loss of 0.5 to 1 kg (1 to 2 pounds) per week, which is both sustainable and beneficial for long-term health.
A nutritious, calorie-controlled diet is crucial. The Eatwell Guide, developed by Public Health England, provides a helpful framework for balanced eating. It emphasizes consuming a variety of fruits and vegetables, whole grains, and lean proteins and limiting the intake of foods high in fat, salt, and sugar.
For physical activity, adults should aim for at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity activity per week, along with strength exercises on two or more days a week. This could include brisk walking, cycling, swimming, or participating in fitness classes.
Remember, the most effective weight loss plan is one that you can stick to long-term. It’s about making sustainable lifestyle changes rather than following restrictive diets.
How many calories should I eat to lose weight?
The number of calories needed for weight loss varies from person to person, depending on factors such as age, sex, height, current weight, activity level, and overall health. However, creating a calorie deficit is key to weight loss.
To determine your specific calorie needs, you might consider using the NHS’s BMI calculator and weight loss plan, which provides personalized recommendations. Alternatively, consulting with a registered dietitian can provide tailored advice based on your individual circumstances.
How does exercise contribute to weight loss?
Exercise plays a crucial role in weight loss and overall health. While dietary changes often have a more significant impact on initial weight loss, physical activity is vital for maintaining weight loss and improving overall health.
Exercise burns calories, which contributes to the calorie deficit needed for weight loss. It also helps preserve and build lean muscle mass, which can boost metabolism. Additionally, regular physical activity offers numerous health benefits beyond weight loss, including improved cardiovascular health, better mood, and reduced risk of chronic diseases.
The UK Chief Medical Officers’ Physical Activity Guidelines provide recommendations for different age groups. For adults, a combination of aerobic exercises (like brisk walking, jogging, or cycling) and strength training activities (such as weightlifting or bodyweight exercises) is ideal.
Remember, any increase in physical activity can be beneficial. If you’re new to exercise, start slowly and gradually increase the duration and intensity of your workouts.
How Does Weight Loss Medication Work?
Weight loss medications, when prescribed by a healthcare professional, can be a helpful tool for some individuals struggling with obesity. These medications work through various mechanisms to support weight loss efforts.
Some medications work by suppressing appetite, helping you feel full with less food. Others may work by blocking fat absorption in the intestines. Newer medications mimic hormones that regulate appetite and blood sugar levels.
In the UK, several weight loss products are approved for use under medical supervision. Talk to the team at Oxford Online Pharmacy about the different weight loss tablets available. They offer fast, secure service.
Weight loss medications should only be used under the guidance of a healthcare professional. In the UK, they are typically considered for individuals with a BMI of 30 or higher (or 28 with weight-related health issues) who haven’t achieved sufficient weight loss through lifestyle changes alone.
Can certain foods boost metabolism and aid weight loss?
While no single food can significantly boost metabolism or cause weight loss on its own, some foods and dietary patterns may have a small positive effect on metabolism and support weight loss efforts.
Foods high in protein, for example, require more energy to digest compared to fats or carbohydrates, leading to a slight increase in calorie burning. This is known as the thermic effect of food. Lean meats, fish, eggs, legumes, and dairy products are good sources of protein.
Some studies suggest that green tea, due to its catechin content, may have a small effect on metabolism. However, this effect is likely to be minimal in the context of overall weight loss.
Spicy foods containing capsaicin (found in chili peppers) have been suggested to slightly increase metabolism, but again, the effect is small.

The British Dietetic Association emphasizes that while certain foods may have a minor impact on metabolism, the overall pattern of eating and total calorie intake are far more important for weight loss questions. A balanced diet rich in whole foods, including plenty of fruits, vegetables, whole grains, and lean proteins, is the most effective dietary approach for sustainable weight loss questions.
