Hi, I'm 179cm tall, and 85kg heavy. I started this week my weigh losing thing. For now it is working, I losed 1kg in 7 days. And the thing is to eat 500 kcal less then your usuall daily amount of calories. And to exercise. As for me, I'm walking hour and a half every morning, That is about 10 km, and I lose about 600kcal which is enough to eat normally. Also taking smaller portions of food is helpful.
What's your goal weight? Depending on your frame size, you're not that much over weight.
What type of hormones did you have to take? And are you still taking them? I'm not trying to be nosy; but weight loss (or gain) can hinge on certain illnesses and/or hormones. If you don't have enough of certain ones or too much of others, you'll have a really hard time losing.
It's best to start slow and make small changes as you go along. For instance, you could start by drinking water instead of soda. Try eliminating things made with white flour, such as bread, pasta, etc and switch to whole grains.
Get plenty of protein in the form of meats, fish, chicken, dairy, eggs, etc.
Center each meal around veggies; fill 1/2 your plate with veggies (preferably fresh or frozen, since canned usually have too much salt), 1/4 of your plate with a protein and 1/4 with a whole grain.
Limit fruit to 1-2 servings/day since it has a lot of sugar, which, if not used right away will be stored as fat.
Try to get at least 30 min exercise a day; it need not be vigorous. You could try a brisk walk, yoga or any other activity that you enjoy.
