Dump carbs (bread, biscuits, cakes, pasta, potatoes, pizza, crisps, etc) & avoid obvious sugars like Ice Cream / Chocolate for 4 weeks and I can assure you will be losing 1-2 lbs per week.
I've never calorie counted.
Mainly eating a lot of mixed salads with chicken or fish or Meat & Veg. Plain yogurt & fruit for deserts.
Every 1 mile you walk is around 100 calories burned.
EAT LESS MOVE MORE.
Homemade coleslaw with a plain yogurt instead of mayo dressing is really very filling and economical too. If you need to snack it is not a bad choice and a bit more interesting than eating a raw carrot. Sometimes I will add apples or beetroot.
Protein - a chicken portion will make you feel fuller for longer.
Fish - Sardines, which are quite strong tasting are great to add to salads and are rich in Omega 3.
Dairy - love to add Feta, Goat's cheese, or light Mozzarella to a salad.
I tend to eat from scratch and never buy processed or pre-prepared food except frozen vegetables. I've never seen the appeal of fast food (KFC, McDonalds, etc) but that might just be my French background. Not partial to greasy, fried food like chips either.
