Why you need vegetables to lose weight

Everyone knows vegetables are good for you, don’t they? They are healthy and filling for very few calories!

The best vegetables are those with low-calorie density. Basically, we are talking about healthier vegetables – potatoes don’t count but butternut squash is much healthier for example!

This means if you eat 100g of spinach, for example, it is just 23 calories and obviously, 100g of anything would fill you up significantly. On the other hand, 100g of crisps, which would be just as filling, is around 536 calories!

Eating this soup for weight loss

It is of course important to check yourself any plan you follow and remember all nutritional information and ingredients are found in the recipe card below.

Soup making tips

If you enjoy soup then these tips could help you.

Use reduced or yellow sticker vegetables where you can, you wont taste any difference but it will save money.

If you use a soup maker remember to defrost any frozen vegetables first as it works much more smoothly that way.

Soup is a great snack on cold winter evenings and could be a good alternative to other comfort foods. If you always make a little extra and freeze some you could have a choice in the freezer every time you need a snack or a bit of warmth.

Soup is a great way to get extra vegetables into your diet. Why not add a mug of this butternut squash soup to a meal that doesn’t have vegetables in as an alternative to a side portion of vegetables for a change?

The importance of adding vegetables to your meals

If you follow Slimming World then you will know many vegetables are referred to as speed foods.

Vegetables are low in calories compared to their density. This essentially means that they fill you up for very few calories.

The more vegetables you have in a meal either as a side dish or mixed in with the meal itself the lower-calorie the meal tends to be. A filling but low-calorie meal is perfect for weight loss.

All my recipes include vegetables where possible but do feel free to add more as an accompaniment when you can. Always choose vegetables that you enjoy because otherwise you will begrudge eating them and are more likely to before long stop cooking them at all.

Trying vegetables cooked differently or with herbs and spices can make them a little more exciting too.

Butternut squash tips

If you are put off using a butternut squash because it is hard to peel then these tips could help you out.

Instead of trying to scoop all the seeds out just cut around them. This is much easier as the stringy seeds can be difficult to remove.

Cut a butternut squash in half length-ways and microwave for 5 minutes to soften it slightly so it is easier to peel off the skin with a potato peeler.

Consider leaving the skin on. In some recipes, like this roasted red pepper and butternut squash soup, it really will do no harm to leave the skin on. A chunky soup for example that has been well-cooked can be just as nice with the butternut squash cut into chunks with the skin on.

If you really don’t want to peel a butternut squash then buy ready cut cubes in the fridge or freezers of the supermarket!

Why you should enjoy desserts on a diet

If you are following a diet you will know how careful you feel you should be with your calories, syns or points. One good way to make your smaller dessert more filling is to add fruit or another low-calorie food. Fat-free fromage frais is a great choice and a great addition to most desserts or have a smaller piece.

If you prefer you can add a little flavouring or sweetener too. My favourite sweetener is Canderel Sugarly.

Do you ever have a glass of water before your dessert? Next time give it a try, you will naturally eat less as the water fills you up a little. A perfect way to enjoy the dessert you want and still lose weight.
