If you're currently following a low carb eating plan, or you're looking to reduce your carb intake, these low carb lunch ideas will make preparing a midday meal so much easier.

The NHS recommends that we consume 260g of carbs daily. A low carb diet usually requires that you eat half that – so 130g carbs or less a day. Some diets such as the Keto diet only allow a daily intake of 50g or less in order to reach the fat-burning stage of ketosis (though it's strongly advised you speak to a health professional before trying this). If followed correctly, a low carb diet can help you lose weight, prevent sugar crashes and help manage diabetes.

If you want to eat low carb recipes throughout the week, aim for 30g or under per meal. To create easy low carb lunches focus on protein such as lean meat, eggs, tofu, nuts, and seeds, and limit or eliminate really starchy foods such as bread, potatoes, pasta, rice, and certainly avoid sugar. "Use less rice and bulk lunches up with cauliflower rice instead, or opt for one slice of toast loaded up with eggs and avocado rather than two slices of toast with butter and jam," says nutritionist Jenna Hope from Jenna Hope Nutrition.

"Choose your foods carefully, as certain food products can increase your carb intake while providing little to no nutritional value." comments nutritionist Daniel Harris. "As a rule of thumb, opt for low carb yet high protein foods such as chicken, 'above ground' vegetables, such as cauliflower, and alternatives to starchy foods such as bread and pasta. Equally, to maintain your energy levels for the afternoon ahead, opt for low sugar foods to avoid dealing with the dreaded afternoon crash."

Prawns, however, are a great source of vitamins and minerals and contain calcium and iron which helps the heart and supports the immune system. Per 100g of cooked prawns, they contain only 0.2g of carbs, making them a great ingredient for a low carb diet."

Soft cheese is a great source of fat which is low in carbs too." comments nutritionist Daniel Harris.

"Butternut squash is a low-carb and keto diet dream as despite being a starchier vegetable, it is naturally low in carbs so can easily be incorporated into low carb and keto diets. Squash actually has a very similar nutrient profile to courgette, as they are high in vitamin c yet contain only 3g of carbohydrate per serving," adds Daniel.
