Three easy ways to cut down on calories…


Reduce your oil usage

1 tbsp of oil is 110 calories! So reducing this to 1 tsp reduces this by 1/3, saving you calories from something that has little nutritional benefit. A good tip for greatly reducing your oil intake is to use water instead of oil when roasting or frying. Often when frying you are looking to soften the ingredients, which can be done just as well with water. One of the benefits of roasting with water, is that as this evaporates at the start of cooking, it softens the ingredient, and once fully evaporated can then get nice and crisp.

If you are going to use oil when roasting, try adding the ingredient to a bowl first, before pouring in a little oil and tossing well. You’ll find that a little oil goes a long way when done like this. Putting the ingredient into the tray first, then drizzling with oil often leads to an excess of oil being used.


Cut down on carbs

Keeping your carbohydrate intake down also helps as these are calorie-rich foods. Try swapping carbohydrates for something a little healthier. Most supermarkets now stock butternut squash sheets, which are great in lasagnes. Try swapping pasta and spaghetti for courgetti as it’s lower in calories, or white rice for cauliflower rice. Use more wholewheat pastas and brown rice, these have a much higher nutritional benefit, and are much better for you.


Watch your portion size

Portion sizes are also key when eating healthy. The recommended servings are much smaller than most people think, meaning that your healthy meal soon becomes less so, due to the amount you’re eating. Just 80g of cooked rice is a portion and 70g for lean meat – the size of a deck of cards. Learning these and then bulking a meal out with salad or veg can keep a meal healthy.
