Normally I am starving when I finish exercising. I guess if I exercise earlier in the afternoon and have something to eat after that, say about 5pm, then no I'm not very hungry for dinner but if I start exercising closer to dinner time, finish the exercise, come inside to cook, then I don't think I have a loss appetite. O to have a loss of appetite!!
Don't think that will ever be one of my problems.
I think you should listen to your body Kim. Maybe you should have more for lunch to get to your 1200 calories. I try not to have a big tea as much as possible, and find that I can drop weight fairly quickly if I skip dinner all together. You should maybe try to eat say 400 cals for breaky, 100 cals for a snack, 350cals for lunch, another 100 for snack, and the remaining(I'm not working that out!!!) for dinner. Just as a rough guide. Not sure what you are eating and how many calories at each meal but as a rough guide maybe you could change your largest meal to lunch time, if you are able to. Your lifestyle and work commits may not allow it.
