Consider meals to be made primarily of vegetables and choose healthy proteins. Make breakfast a big meal, lunch slightly smaller. I don't know if you do the tea then supper or just have tea as the final meal, but make the final meal light. My last meal of the day is a bowl of oatmeal with a handful of walnuts and a heaping teaspoon of cinnamon with a little brown sugar sprinkled on it. That's a cholesterol killer of a meal while the cinnamon may help balance blood sugars as well as add flavor. I also like herring snacks which are excellent for you as herring is one of the most unpolluted fish there is and it's superhigh in Omega 3 fatty acids. I cook with olive oil, another healthy fat, and use lots of fresh vegetables in my cooking. I'm very fond of shellfish so I eat a lot of that and it too is extremely healthy for you.
When it comes to carbs, you want to stick with complex carbs. Like rather than have a white dinner roll with butter, instead choose a whole wheat dinner roll with goose fat (like the French) or flavored olive oil. Cornbread is good too.
Many nights I make a pasta dish with whole wheat pasta (some taste awful but I like Ronzonis) with a high-quality tomato sauce and either scallops or shrimp or clams tossed in. Or I get turkey Italian sausage. I can eat this combination until I'm really full and still I lose weight.
Stay far away from anything with high fructose corn syrup and learn to avoid refined sugars and sugar substitutes. It's easy to get addicted to sugar and many doctors and nutritionists believe that it contributes to a host of metabolic problems. A little is OK now and then, but try to reduce it as much as possible. This is really tough as you will crave sugar when you don't get it. The best thing to do is drink a glass of water when that happens or eat a peeled raw carrot or a few pickled beets.
You really don't have to starve to lose weight. I eat as much as I ever did and sure I treat myself to ice cream or even a Big Mac now and then. I'm losing weight and doing so safely and gradually. If I don't eat healthy as I should because I'm traveling or out for a meal, it doesn't phase me because the bulk of my eating is still healthy and filling and flavorful and one of the worst things you can do is view grabbing a candy bar or ordering a food you shouldn't and berating yourself for doing it. You're not falling off a wagon, you haven't just doomed anything. Some people make a point to eat well every day but on their night out at a restaurant, they order whatever they like. Knowing they can look forward to a time not too far off when you can order whatever you like can help keep you on course. Eating well isn't a penitentary of steamed vegetables and skinless chicken; it's changing what you eat. You will find that when you eat a lot of vegetables and whole grains that you will eat a lot less just because it's more filling.
I frequently stir fry in my wok. Wok cooking essentially puts my entire meal into one pot and I can mix all kinds of things together and then add a spicy sauce. I'll take broccoli, carrots, onions, peppers, pineapple, cashews or peanuts, garlic, ginger, scallops or shrimp or calamari, and then finish with a good quality Chinese red chili sauce (like the Chinese would eat themselves). What's really nice is that I'm frying my food, not steaming it, and the amount of olive oil I use is extremely low and the cooking technique coats everything with oil so you get a wonderful savory flavor you don't get with steaming.
Cut out the processed foods, snack on healthy stuff like fruit, herring, vegetables, or whole grains (whole grain chips with a healthy homemade salsa is wonderful!), stay far away from high-fructose corn syrup and transfats, and you should do fine. What do I drink? Unsweetened decaf ice tea and lots of it. I'm trying to work in a glass of red wine for its benefits but I don't like wine much.
The other important thing is not to do this all at once. Gradually work it into your diet. Cut one thing, add another then get used to it then cut another thing and add another. Keep doing that so that you're not going cold turkey. It's much easier to keep on track.
This really isn't a diet so much as an eating philosophy. That's what's really nice. I don't count calories or anything like that. I just watch what I eat and I never go to bed hungry.
Definitely start exercising but I wouldn't go for an hour at first. Take 15 minutes and then gradually add to that, like a minute every few days until you work up to an hour. I've heard that it takes 2 weeks to make something a habit you're much more likely to repeat than not and if you face a daunting task, "A WHOLE hour??!" you're much less likely to keep doing it.

Don't kick yourself when you give-in
Set aside one night a week to eat whatever it is you love and isn't the best for you (eat pizza, garlic knots, and ice cream). Knock yourself out.
Watch refined sugars, high fructose corn syrup, and try to avoid artificial sweeteners as well because they can cause sugar cravings though Sucralose (found in some diet sodas) may not.
