Make sure you're actually eating enough. Lots of people think to lose weight, you need to eat less. It's often the case that you may not be eating enough calories per day. I calculated for myself that I should be eating about 2000-2400 cals per day for my very limited activity and body weight. That is actually lots of good healthy food, and I actually often struggle to eat it.
I also need to make a point of eating enough protein. I really struggle with that too. I often only eat meat at dinner, and have very little other sources of it. So I have upped my intake of eggs at breakfast, or tuna sandwiches, or nuts or yogurt snacks, or smoothies with protein powder added.
