Soup and protein: why this combination works for weight loss
High-protein soup helps with weight loss because it lets you eat a decent volume of food for relatively few calories. A 400 ml bowl containing 20 grams of protein physically fills the stomach, slows gastric emptying and triggers satiety hormones such as PYY and GLP-1. The result is less hunger in the hours that follow, without having to force a calorie deficit through willpower alone.
Research published in the European Journal of Clinical Nutrition found that participants who had soup before lunch went on to eat around 20% fewer calories at their next meal than those in the control group. That effect becomes even stronger when the soup is also protein-rich, since protein is the most satiating macronutrient per kilocalorie of all.
The Dutch Nutrition Centre (Voedingscentrum) recommends a daily protein intake of 0.83 grams per kilogram of bodyweight, a reference figure widely used across Europe. For a woman weighing 70 kg, that works out at 58 grams a day. When a single meal already provides 20-25 grams for under 200 calories, you've plenty of room left for the rest of the day. That's exactly what the recipes below deliver.

8 high-protein soups under 200 calories: at a glance
The table below shows eight recipes with their macros per serving of roughly 400 ml. Preparation time includes chopping and prepping. The protein source for each recipe is listed so you can swap ingredients easily based on what's already in your kitchen.
| Soup | kcal | Protein (g) | Protein source | Prep time |
|---|---|---|---|---|
| Chicken and vegetable soup | 145 | 22 | Chicken breast | 25 min |
| Red lentil soup | 175 | 18 | Red lentils | 30 min |
| Tomato and kidney bean soup | 160 | 16 | Kidney beans | 20 min |
| Miso-tofu soup | 110 | 14 | Firm tofu | 15 min |
| Cold Greek yoghurt and cucumber soup | 130 | 12 | 0% Greek yoghurt | 10 min |
| Split pea soup with lean ham | 195 | 21 | Split peas + ham | 40 min |
| Spinach and cottage cheese soup | 155 | 19 | Cottage cheese | 20 min |
| Turkey and pepper soup | 165 | 23 | Minced turkey | 30 min |
Chicken and vegetable soup and turkey and pepper soup score highest for protein per serving, at 22 and 23 grams respectively, while both stay comfortably under 200 calories. That's a ratio of roughly 0.15 grams of protein per kilocalorie, which actually outperforms most budget protein shakes on the market.
How to turn an ordinary soup into a high-protein one
Most soups, whether from a carton or homemade with vegetables and stock, contain just 3-6 grams of protein per serving. That's not much. A few simple tweaks can double or triple that figure without pushing the calories up significantly.
Add a lean protein source
Chicken breast, turkey, prawns and white fish are the most efficient options. 100 grams of cooked chicken breast gives you around 31 grams of protein for roughly 165 calories. Add 75 grams to a vegetable soup and you've already boosted it by 23 grams of protein for under 125 calories.
Use pulses as your base
Red lentils, chickpeas and split peas partially break down during cooking, thickening soup naturally without any cream. Per 100 grams of cooked red lentils, you get 9 grams of protein for 116 calories. They also bring fibre, which flattens the glycaemic response.
Stir cottage cheese or Greek yoghurt through the soup
This works well with creamy soups like tomato, courgette or pumpkin. Let the soup cool slightly (below 70°C) before adding the dairy, otherwise it will split. Cottage cheese provides 11 grams of protein per 100 grams for 85 calories. 0% Greek yoghurt gives 10 grams of protein per 100 grams for 57 calories.
Miso paste as a stock base
White miso brings flavour but also 13 grams of protein per 100 grams. A tablespoon (18 grams) already adds 2.3 grams of protein to your base, plus a depth of umami that makes the soup taste fuller. Go easy on the quantity, though, as miso is high in sodium (around 3,700 mg per 100 grams).
Protein powder in soup
This might sound unusual, but neutral or lightly savoury protein powders dissolve well in hot soup. A 25-gram scoop adds around 20 grams of protein for roughly 90 calories. Mix it with a small amount of cold liquid first before stirring it into the hot soup, otherwise it will clump.

Ready-made vs homemade: which works better?
Making your own soup gives you full control over ingredients, sodium and macros. But let's be honest, a 40-minute split pea soup isn't always realistic on a hectic working day.
Ready-made supermarket soups typically contain just 3-7 grams of protein per serving, which isn't enough for a proper protein meal. Most shop-bought soups are primarily carbohydrate or fat-driven rather than protein-driven.
| Type | Avg. protein/serving | Avg. kcal/serving | Sodium content | Practical? |
|---|---|---|---|---|
| Supermarket soup (carton) | 3-7 g | 80-150 | High (600-1000 mg) | Yes |
| Homemade (basic recipe) | 15-23 g | 110-195 | Controllable | Moderate |
| Bioteïne meal soup | 25-30 g | 150-200 | Controlled | Yes |
The Bioteïne meal soups are designed for people who want to hit their protein and calorie targets without cooking from scratch every day. They meet the standards of a clinical protein diet: at least 25 grams of protein per serving, under 200 calories, with controlled sodium levels.
Pitfalls that undermine your weight loss results
Soup has a healthy reputation, but a few common habits don't quite deserve that halo.
Cream and full-fat coconut milk
A splash of cream sounds harmless. It isn't. A tablespoon of double cream (15 ml) delivers 55 calories, almost entirely from fat. Add two tablespoons per serving and you've tacked on 110 calories without any protein at all. Swap cream for 0% Greek yoghurt or a small amount of high-protein milk (1.5% fat).
Bread on the side
A slice of bread with soup is a habitual pairing for many. One slice of wholemeal bread adds 75-90 calories and 2-3 grams of protein. Two slices add 150-180 calories, effectively doubling the calories of your soup meal. Opt for an extra portion of soup instead, or a Bioteïne protein bar if you fancy something to chew on.
Compensating for low protein with sheer volume
If your soup is low in protein, you'll be hungry again within the hour and reaching for something else. That's not a willpower problem, it's physiology. The fix isn't eating less, it's building your meals more intelligently.
Sodium overload with daily use
The British Dietetic Association recommends no more than 6 grams of salt a day (2,400 mg sodium). Some ready-made soups already contain 900-1,100 mg of sodium per serving. Have them daily and that adds up fast. Cooking with a low-sodium stock, or using miso sparingly, is the safer long-term approach.
Meal prep: soup for five days in one go
Soup might be the single most meal-prep-friendly dish there is. Most of the recipes above scale up easily to 4-6 servings in one 30-45 minute cooking session.
A practical approach for the week ahead:
- On Sunday, cook a double batch of lentil soup and a double batch of chicken and vegetable soup.
- Divide into 400 ml portions in sealable containers.
- Soup keeps in the fridge for 4 days. For longer storage, use the freezer (up to 3 months).
- Label each container with a name and date. It sounds excessive, but it stops you guessing what's in there by Thursday.
- Add fresh herbs (parsley, coriander) after reheating rather than during cooking, to preserve the flavour better.
When you need to swap in or top up meals on busy days, Bioteïne ready meals slot straight into your meal-prep routine. They just need heating up and deliver the same macros as a homemade recipe.
For a structured approach across several weeks, including which soups and meals suit which phase, see the Bioteïne 4-phase system.
Bioteïne protein soups: for when cooking isn't an option
Not every day allows time by the hob. The Bioteïne meal range was developed as a direct replacement for homemade protein meals, soups included. Every serving contains at least 25 grams of protein, fewer than 200 calories, and fits within a clinical protein diet.
They're formulated in line with the standards of the Cambridge Method and comparable clinically supervised diet protocols. That means no unnecessary additives, no hidden sugars and no diluted macros.
For anyone just starting out on a protein diet, the Bioteïne starter pack is a sensible first step. It includes a selection of meals, shakes and snacks that keep the first two weeks fully structured, with no need to work out the numbers yourself.

Frequently asked questions
How much protein should a high-protein soup contain?
A soup only counts as high-protein once it delivers at least 15 grams of protein per 400 ml serving. Tailor your soup to your overall daily target: for a 70 kg woman, that's around 58 grams a day. One soup meal providing 20 grams covers roughly 35% of that requirement.
Can I eat soup every day as a meal replacement?
Yes, as long as the soup contains enough protein (at least 20 grams), fibre and micronutrients. Rotate different types to get a broad range of micronutrients. Mono-diets built around a single soup type aren't recommended for longer than three days without professional guidance.
Do you lose weight faster with soup than with solid meals?
Soup has a high water volume, which fills the stomach and triggers satiety signals. Studies show an average 20% drop in calorie intake at the next meal after eating soup. It's not a magic bullet on its own, but it does make sticking to a calorie deficit noticeably easier.
What's the best protein source for soup?
Chicken breast and turkey score highest for protein per kilocalorie, at around 31 grams of protein per 100 grams for 165 calories. For plant-based options, red lentils are the most efficient: 9 grams of protein per 100 grams cooked, with a good balance of fibre and complex carbohydrates.
Can I use soup during a protein diet or VLCD?
High-protein soup fits well within a protein diet, provided the calories and macros align with the protocol you're following. Within a VLCD (Very Low Calorie Diet), most homemade soups are too low in calories and micronutrients. Use clinically formulated meal replacements instead.
How long does homemade protein soup keep?
Three to four days in the fridge, up to 3 months in the freezer. Soups containing dairy (cottage cheese, yoghurt) don't freeze as well, as the texture changes on thawing. It's best not to freeze dairy-based soups; keep them chilled instead and use within 3 days.
Is soup with bread still healthy?
Bread on the side adds 75 to 180 calories per serving, depending on the type and amount. If weight loss is your goal, bread adds little protein for those extra calories. If you fancy something to chew, choose a high-protein snack instead of bread.
Which Bioteïne products pair well with soup as a top-up?
A soup meal of 20-25 grams of protein sometimes leaves you 10-15 grams short of your daily target. A Bioteïne protein shake, a protein biscuit or a protein snack closes that gap without pushing you over your calorie ceiling.
