Some lovely ideas in the link below. The Mediterranean diet is not a 'diet' but the best way of eating delicious and healthy foods, including lots of vegetables.

Instead of rice and pasta, eat cauliflower and broccoli. Roast vegetables are easy any yummy: butternut squash, parsnips, beetroot, carrots, peppers, tomatoes. I often make extra and put the leftovers in a stew, made with tomato or curry sauce, the next day.
Don't keep rubbish food (biscuits, icecream, milk chocolate) in the house. A square of dark, high-cocoa chocolate is fine. No bread other than a bit of pitta bread. Banana bread is still a cake and should be an occasional treat. Snack on melon, cantaloupe, grapes, apricots, apples, satsumas, carrots........ so much to choose from!
Keep boiled eggs in the fridge. Excellent if you think you're starving - only 70 calories each.
Remember to stay hydrated. Often, when we think we're hungry we're actually thirsty. But try not to drink calories, especially sugary sodas and booze.
Delay breakfast until 11 and don't eat after 7 pm. AKA intermittent fasting. Very effective if you don't eat excessively in between.
Lastly: exercise. Minimal calory loss but a powerful motivator, not to mention the resulting toned body. Get yourself some 3-5 kg dumbbells and aim for at least 20-30 minutes a day - try Growingannanas, Heather Robertson, Rebecca Louise, Jo Wicks, Caroline Girvan on YouTube. Try to walk - at a fair pace! - at least 10,000 steps a day.
Once all this becomes a way of life, the idea of wasting hours on the sofa eating biscuits will have lost its appeal.
