Hey hunny, im so sorry for you loss.
Your stuck in the same place i am. I need to lose about 75lbs to be healthy in my eyes and even these silly bmi charts think that is over weight. But my dietican think's that is reasonable for me. So i'm sticking with it.
This is what he told me:
DRINKS:
2 litres of water a day, i hate plain tap water so i opted for flavoured water. Same effect and it's a good place to start to switch to plain water. Or if you like your fizzy's. Go for diet to start off with and wean your self off them. I don't go for anything else but irn bru sugar free... 4 calories for a 500ml bottle and nothing else in it!
EATING:
A bigger breakfast leading to a small dinner. This way you are burning the calories off through-out the day. Rather then having a large dinner and sitting on the sofa watching tv (Will all store as fat.) When you have your dinner do something in the evening, get an exercise bike that way you can still watch TV, or try a fitness dvd or game. I've heard Zumba is good but i've never tested it (i'm deciding weather to buy the wii version).
Write up a food plan for the week that way your not deciding what to eat at 4:30 and decide a take-away is better because you don't want to cook. Also you know what to be buying when you do shopping.
NO meals after 6pm!!!
SNACKS:
Fruit or cereal bars, healthy but still filling. This way if you get peckish after 6pm it's healthy for you. Even a couple of cracker's won't hurt, but nothing more then 100 calories.
EXERCISE:
Walking is very good for you, the more the better!
But you need to mix it up a bit, a bit of walking one day and then maybe some swimming or an exercise bike the next.
I couldn't stomach a gym at the moment either. So i'll do it my own personal place. As i said before i've heard zumba is good to lose weight, i'm not sure myself maybe other ladies on here have tried it.
Anything works really as long as you are raising your heart rate. Find something that suits you and fit's around your life style.
I use MyFitnessPal to moniter everything i eat and do, you just put in what you eat and it will add all the nutrients up for you. But be honest with it, no shame in going over a little. About 2000 calories is best for you at the moment, same as me as i use to eat more. But this site has really helped me watch what i eat.
Get a calorie counter to see how many calories your burning by just walking. You could be surprised!!
Anyways hun i hope this helps you a bit.
Good Luck hun!!! xx
