Don't demonize food by cutting out food groups. Eat from all food groups but make smarter choices and reduce portions somewhat.
Each meal should include a lean protein, and this includes beans and pulses and fish. Add a carbohydrate, such as brown rice, a jacket potato (keep the skin, it's where the vit C is) or a baked sweet potato. Then load up the plate with salad or multi coloured veggies. The wider range of colours you include, the wider range of vitamins you will be getting. Shoot for a wide range throughout the day and week.
For dessert, choose fruit and low fat, low sugar yoghurt. Beter still, choose natural yoghurt and flavour it yourself with a home made Summer fruit puree. Summer is the best time: you have all those nectarines, peaches, watermelon, canteloupe, blueberries, raspberries, cherries..... enjoy them! And lose the chocolate bars and cookies.
Eating in this way, you eat for best health, not just weight loss.
