well at least I started the gym now.......

Advanced planning is your friend. If you log your food ahead of time you will find it easier to stick to.

If you know cooking in the evenings is too much effort, account for that. Cook a big batch of something at the weekend which you can just microwave, or fill the fridge with healthy foods to pick at - veggie sticks, individual cheese portions, cooked chicken, slices of ham, salad packets, pieces of fruit, yoghurts, crackers etc. Things which are easy to portion out and you can just pick.

You have to find something that's sustainable for you. It's a lifetime change.
Going to the gym is an excellent start to your health journey. Now, if you can add food to that, you would be in real business.

You will have to find out how many calories you need each day­.

For that, you need to find out your Total Daily Energy Expenditure (TDEE). This would be the total calories you burn in a day, functioning and all. You can find many calculators online for this purpose, here is one that I found: http://www.fitnessfrog.com/calculators/tdee-calculator.html.

Then, you need to find out your Basal Metabolic Rate (BMR). This would be the number of calories you'd burn if you stayed in bed all day. You can calculate yours here: http://www.bmi-calculator.net/bmr-calculator/

When you have those two numbers, you need to evaluate how many calories you would need every day in order to lose weight and maintain it. My TDEE is 2410, and my BMR is 1757. Now I know for a fact that I can't go under 1757, because that's how many calories I would burn if I was in a coma. If I go under this number, then it is damageable for my body and my weight loss. My TDEE is 2410, so that's approximately the number of calories I can eat each day without losing or gaining any weight. The calories you need to get every day needs to be lower than that. You need to have a deficit in your TDEE in order to lose weight, but in my case I know I can't go lower than 1757. I decided to set my calories each day to 2000. If I do that, it means that I have a deficit of 410 calories every day. That equals a deficit of 2870 per week. Now, knowing that a pound of fat = 3500 calories, I would lose more than half a pound every week. That's not bad at all! And if I exercise, then I can allow myself more.

It's easy to put your nutrition in perspective when you have numbers to help you. It helps to start logging your meals because you realize how much stuff you eat and how many calories are in there. It's so easy to munch endlessly on potato chips when you do not really know their value. You can allow yourself to eat whatever you want, in moderation. This is the key. There is no need to be obsessed, no need to only feed yourself with celery sticks and lettuce. You just need balance and motivation. Look for healthy recipes in the forums. Read articles online. Surround yourself with people with the same goals.

And never give up. That's the most important part. I believe you can do it.

Take care. xx

I buy lots and lots of single serving things. My fridge is full of diced peaches (in water NOT syrup), light yogurt, baby carrots, celery, hummus, applesauce, etc. That way when i want a snack its always low cal and fairly healthy. In the mornings I combine 3 or 4 of the single servings items to have a healthy breakfast. My freezer is also full of lean cuisines and smart ones because they are so quick, easy, and low cal.
