You have done amazingly well to gather up your conviction and loose that weight since November, especially over the Christmas period. I think you're absolutely right about doing what you enjoy - walking and making gradual life style changes and loosing weight slowly. There's loads of sat fat usually hidden in convenience foods. I read somewhere once that the firmer fat is on meat, the higher in sat fat. I tend not to use any spread unless I'm eating Marmite or having a treat of butter, but OH uses an olive oil spread. Don't know how they compare with lowering cholesterol. I chuck pumpkin seeds and sunflower seeds (about 1/2 - 1 tsp each) which are supposed to do the same, on my porridge and cereal. As fior T1, should be easier for me because I can compensate any intake of carbs with the insulin, once I've got the balance right, but there are other factors which can make the old bs go up and down, ah well....
Anyhow, keep up the good work and enjoy life too! Hope your holiday wasn't totally ruined!
