When you don't have a lot to lose, you sometimes need to be more strict on your diet. Track all your food honestly. You need to know how many calories you are taking in and play around with them to see what helps you lose, but is sustainable so you can keep doing it without feeling too deprived. Measuring cups, measuring spoons and a food scale are great tools. You would be surprised how much more you are eating than you think you are eating. Drink water. It flushes out sodium and keeps things moving. Get plenty of protein and high fiber foods. They tend to help us lose better than any other food groups. Eat less processed foods. Sometimes it's about WHAT your are eating as much as HOW MUCH. Google "power foods" that help you lose. Green tea is a great to drink to rev your metabolism. I turn it in to iced green tea. Go to Pinterest.com and type in "fitness motivation or inspiration". It always helps to get me moving and motivated to stick with it.
