One meal at a time, one day at a time and you'll start to see changes. All you need to do is plan ahead for your meals, try better quality or healthier take outs if you're not into cooking, or cook simple meats with vegetables. Eat healthy snacks like fruit or nuts. Drink plenty of water. Thinking consciously about what goes in your mouth and what your goal is, can help to avoid over eating.

Log your meals and snacks as you eat them and it will give you your daily tally of how much you have eaten and how many calories are left on your allowance. Try not to go too low too quickly. If you eat large meals, cut down slowly or you'll feel like you're starving yourself and you'll only end up eating a big binge meal and feeling guilty/hopeless/sad for it and stopping altogether.

Have faith that you can do it. If there is more output than input, weight will go down. If there is more input than output, weight will go up. Being somewhat of a hermit may not be conducive to getting a lot of exercise, but even try walks around your house and lifting dumbbells or other items in your house in place of them as a form of exercise.

Most of all, don't give up.
