To lose weight, really it's best not to eat anything after 8pm and it's best not to drink caffeinated drinks too late either, as they'll stimulate your brain and contribute to waking early to visit the toilet!
Eat protein for breakfast - eggs are best. Bacon/sausage is 'okay' as long as it's grilled. You can eat as many tinned or fresh tomatoes as you like with this meal. If not, after the eggs, eat as much fresh fruit as you like. Bananas are great for energy, potassium and magnesium. You only need 5 raisins to be classed as one of your "5 a day"!
For lunch, a baked potato with beans/coleslaw is a good filling meal. The beans give protein and sugars. The potato has a good quantity of vitamin C just under the skin and is a brilliant source of complex carbo, which will fill you up for longer.
If you are a fan of fried foods, please invest in an 'actifry'. I have the Tefal one, but there are loads on the market now. I cook chips in it using only a tablespoon of oil and they are delicious. Sausages are cooked from frozen and need no fat at all. Chicken can be cooked in it as well - best to cook it with the skin on, for moisture and flavour, but remove the skin before eating it, as there's a huge amount of fat in the skin. I used to say that the skin was the best bit, but after not eating it for a while, I tried a small piece and found it quite revolting!
As a 'snack', if you must indulge after 8pm, try anything with turkey, lettuce or bread. Turkey has dopamine and lettuce contains laudanum which both contribute to sleep. If you like honey, it's a good sweet treat for later on in the day. Honey has enzymes and pollens which help with all sorts of ailments, whilst you sleep. It will also help with any sugar cravings - I have it in coffee instead of sugar and it's rather tasty!
