5-2 Diet Recipe – Spicy Tomato and Lentil Soup
Whether you are trying to follow the 5:2 diet or following a more conventional low-calorie diet, soups are a wonderful thing and this tomato soup, spiced up with chilli or paprika (or both) and thickened with healthy lentils is no exception. Warming, filling and healthy – and very easy and cheap to make, the tomatoes give a rich flavour (they are full of umami) while the lentils are high in protein and fibre (50g of raw lentils have about six times the level of fibre and protein as 100g of potato, a common way to thicken this soup, but bulk up to about the same volume). So if you are following a diet and think soup can’t be filling, try my tomato and lentil soup!
Looking back I guess I’ve done something like the 5:2 diet in the past when I used to have ‘soup days’ once or twice a week if I wanted to lose weight. You can make up soups that are extremely low in calories and very comforting. And tomato soup has a comfort factor for me, perhaps because I grew up on the Heinz variety!
The main thing to remember when following the 5:2 diet plan on fasting days is that you need to avoid cream-based soups – because once you start adding cream, the calories go up really quickly. And, except as a garnish or stirred through at the end, you can’t add the low-fat types of cream or yoghurt and cook with them, because they will split.
This Spicy Tomato and Lentil Soup is a store-cupboard recipe. Most of the ingredients are things you should have in your cupboard already – so it’s perfect for one of those days when you planned to shop and then it started to pour with rain, or you got too busy. The lentils add body to the soup but are also a great nutritional addition because they are high in protein and fibre (although the red ones that I use for cosmetic reasons here are not as high fibre as the posher green puy lentils). 50 grams of dried red lentils is enough for four portions of this soup – adding about 150 calories in total.
A spicy vegetarian or vegan soup (depending on stock and garnish) that is freezable and can be prepared in advance. Serve hot
- 1 Tin Chopped tomatoes
- 1 Medium Onion Finely chopped
- 1/2 Red Chilli De-seeded - or dried chilli flakes to taste
- 50 g Dried Red Lentils
- 1 Carrot Peeled and chopped
- 1 l Chicken or Vegetable Stock I use Knorr touch of taste chicken stock made up with 1.5 teaspoons
- 1 teaspoon Sunflower Oil
- 1 tsp Low-Fat Yoghurt or Creme Fraiche
- 1 stick Celery Chopped
Put the oil in a large heavy bottomed pan on a medium heat and soften the onion, carrot, celery if using and chilli for 8-10 minutes
Pour in the stock and tomatoes and add the lentils
Cook for at least 25 minutes on the hob till the lentils are soft and the mixture has reduced down a little. Check and adjust seasoning, adding salt and pepper as required. If you do not want the soup to get any hotter, remover the chilli at this stage.
Blitz the soup with a wand mixer until nearly smooth
Serve with a dollop of low-fat yoghurt or creme fraiche, or if you prefer with a scattering of crunchy croutons.

This tomato soup recipe has been a winter staple of mine for years. I do experiment with the spices – you can add cumin or cardamom if you like them, and coriander is a nice garnish if you have any (I don’t right now!). I’ve made a spicy but not hot version using sweet paprika too. I have never really worried too much about the calorie content but one of the effects of doing the 5:2 diet is that you do think quite hard about what you are eating in terms of nutrition and calories. I’m also finding that the 5:2 diet is reducing my appetite on non-fasting days – I’m not eating very differently but I AM eating less, and I’m definitely losing weight and feeling better!
