That's some great advice given by Bella. I've been struggling with my weight and with confidence issues resulting from it for years. Recently, I (finally) got tired of feeling sorry for myself and began to do something about it. I've changed my eating habits, and I started doing cardio and light weigh lifting. This combination, from what I understand, is what produces the greatest results for weight loss. There is a site
here that will show about how many calories you can burn over a given amount of time performing certain activities. You just plug in your current weight and a duration.
I've cut the sweets and fattening foods from my diet, and ride my bicycle 6 days a week for 30 to 45 minutes and do some weight lifting 3 or 4 days a week for 15 to 30 minutes. I record everything I eat in a food journal I keep on my computer so I can see what I eat and how much, and I track calories with it as well. I've been at this for one month, and I've lost 15 pounds so far (no idea how many inches - haven't tracked that yet). For the record, I'm 5'10" and 220 pounds.
So you see, it's possible to lose the weight, but it takes work and dedication. And the only way to do it is to just get out there and do it. Don't dwell on the journey, think of the goal. You can do this, and if you need encouragement, you can always find it here.
