Suggestions needed- how to loose weight in a good way?

This may be a bit of a rant, but I’m feeling discouraged and hoping someone here can help me.

A lot of my friends/family/coworkers are talking about how they have lost weight recently and I keep hearing the same things: I gave up chocolate, I gave up drinking, I gave up junk food.

I have nothing to give up. I eat eggs for breakfast, light lunch or skip lunch, and home cooked meal for dinner. I don’t drink, I don’t drink soda, I don’t eat sweets, I already power walk 3 times a day and lift weights 3 days a week. I can’t seem to get rid of this 40# of belly fat. I’m at a loss… I don’t know what to do.

Maybe my fitness routine is lacking. Do any of you think I should be working out every day instead of just 3 days a week?
