Is Soup Good For Weight Loss?
Yes, soup can be a helpful food for weight management when prepared thoughtfully. Broth-based soups with vegetables are low in calories, high in fibre, and help you feel fuller for longer — all key factors in creating the calorie deficit needed for weight loss. However, the type of soup matters significantly. Creamy soups and those high in salt or added sugars may work against your weight loss goals. This guide explains which soups support weight management and how to use them effectively as part of your NHS weight loss strategy.

What Is BMI and Why Does It Matter?
Body Mass Index (BMI) is the most widely used screening tool for assessing whether your weight falls within a healthy range. Used by the NHS, GPs, and weight management services across the UK, BMI provides a quick snapshot of your weight relative to your height. The formula is simple: your weight in kilograms divided by your height in metres squared (kg/m²).
While BMI isn't a perfect measure — it doesn't account for muscle mass, bone density, or fat distribution — it remains the standard first step in identifying potential weight-related health risks including type 2 diabetes, cardiovascular disease, high blood pressure, and certain cancers.
The NHS also recommends adjusted thresholds for people of South Asian, Chinese, or Black African heritage — a BMI of 23 or above is classified as overweight, and 27.5 as obese. Our calculator includes this adjustment as a one-click toggle.
Why Soup Works for Weight Management
Soup is effective for weight management uk for several evidence-based reasons:
- Low calorie density: Broth-based soups contain high water content, meaning you get a large, satisfying portion for fewer calories than solid foods
- Increased satiety: The liquid and fibre combination signals fullness to your brain more effectively than equivalent calories in solid form
- Slower eating: Soup requires you to eat more slowly, giving your brain time to register satisfaction signals — typically taking 20 minutes
- Reduced overall intake: Starting a meal with soup can reduce total calorie consumption by up to 20%, according to nutrition research
Vegetable-based soups particularly support bmi weight loss goals because they're nutrient-dense but calorie-light. A typical vegetable soup contains 80–150 kcal per 300ml serving, making it easy to fit into a calorie deficit without feeling deprived.

Best Soups for Weight Loss and Which to Avoid
Best choices: Clear broths, minestrone, lentil soup, vegetable soup, tomato-based soups, and chicken and vegetable soups are all excellent for weight loss. These typically contain 100–200 kcal per serving and provide protein and fibre.
Avoid: Cream-based soups (bisques, chowders), cheese soups, and coconut-based soups can contain 300–500+ kcal per serving. Canned soups often have high sodium levels, which can increase water retention. Making soup at home gives you complete control over ingredients and portion sizes — use our free progress tracker to monitor your overall calorie intake alongside soup servings.

Frequently Asked Questions
Common questions about BMI, weight loss medications, and our free UK tools.
How much soup should I eat to lose weight?
For weight loss, a 300ml serving of vegetable or broth-based soup is ideal — roughly 100–200 calories. This can be eaten as a meal starter, light lunch, or part of a balanced dinner. Combine with protein (grilled chicken, fish, or legumes) and wholegrain carbohydrates for complete nutrition. Aim to include soup 3–4 times per week as part of your overall weight management strategy.
Can I lose weight eating only soup?
No. A soup-only diet lacks adequate protein, healthy fats, and essential micronutrients needed for long-term health and sustainable weight loss. The NHS recommends a balanced approach including all food groups. Soup works best as part of a varied diet with whole grains, lean protein, fruit, and vegetables. Weight loss of 0.5–1kg per week is considered safe and sustainable.
What about canned or packet soup for weight loss?
Canned and packet soups often contain high sodium (salt), which can cause water retention and mask true fat loss. Many also contain added sugars and preservatives. Homemade soup is always preferable — you control salt, fat, and sugar levels. If using shop-bought soup, check the nutrition label and choose options under 150 kcal per 300ml serving with less than 1g salt per serving.
Does soup work better for weight loss than other foods?
Soup is effective but not uniquely superior — what matters is overall calorie intake and balanced nutrition. Soup's advantage is that it helps with satiety and portion control, making it easier to maintain a calorie deficit. For personalised weight loss guidance, calculate your BMI using our free BMI calculator to understand your starting point, then discuss weight management options with your GP.
Can prescription weight loss medications like Mounjaro or Wegovy be used alongside soup-based diets?
Yes. GLP-1 medications (Mounjaro and Wegovy) work best alongside dietary changes and increased physical activity. Soup can be part of a balanced, reduced-calorie diet alongside these medications. Both Mounjaro and Wegovy are prescription-only and require clinical assessment. Our GLP-1 weight loss calculator can help you explore potential outcomes alongside lifestyle changes including dietary choices. ```
