Way to lose weight

It's been 4 months that I just stayed home and didn't move much compare when I was still working.Not to mention that I cook a lot.So,me and my husband becomes bigger and bigger.It's summer now,so I really have to lose weight so that I could use the clothes that I bought recently and be look good wearing it.Good thing that there are diet pills right now for an option to lose weight.That would be easier for me!:)
