I lost a fair few stone doing 1200 calories and (I hate exercising!) it did encourage me to move more if I wanted to eat more.
It was boring at times though.
Breakfast, - porridge, bagel and cream cheese, scrambled egg whites (very low in calories) turkey bacon, egg muffin, or fruit.
Lunch - 1 roll or sandwich, fruit or vegetables, soup, crackers and dip, small handful of nuts, protein shake or a smoothie.
Dinner - Grilled turkey and vegetables, salmon and new potatoes, stir fry, chicken and veggies with a yorkshire pudding.
Tried to save extra calories for evening wine or chocolate. But that's when I started walking to work and back to gain extras. It does work in the long run and at the very least you develop better eating habits and will find better variations of meals you can swap around.
