- Change everything possible to a low-fat version - cheese, milk etc. Sweetener instead of sugar and low fat spread instead of butter.
- Make sure you eat every 3-4 hours.
- Breakfast should be your biggest meal of the day, lunch the second biggest and dinner should be very small.
- Always eat some form of protein with every meal but only eat carbs with breakfast and lunch (or so I've heard)
- Change all pasta, bread etc. to wholemeal (you said you did with bread but dunno what kinda pasta/rice you have).
- Cut out on red meat and only have it once a week. Have fish 2-3 times a week and chicken, turkey or a vegetarian protein the rest of the time.
- Stay clear from starchy fruit and veg e.g. bananas and potatoes.
- Nuts are fatty, but they're good fats so don't cut those out. Have nuts, seeds and dried fruit for snacks as well as low-fat natural yogurt with things like honey mixed in or low sugar apple sauce. Chop up carrots, cauliflower, cucumber etc. and make your own dips and humus and stuff for crudites which are a great snack or lunch.
- Drunk 2.5 litres of water a day and cut out all fizzy drinks. Have natural and unsweetened fruit juices if you want something other than water but only a small glass and choose green tea instead of normal tea or coffee. Put some lemon in it if you don't like the taste.
As for exercise, if you can't fit in any proper workouts, just make sure you walk as fast as you can around town or whenever. Take the stairs and not the lift.
I'll post some more if i Think of any!
