If you plan on taking an entire year to lose 50 pounds, you can do it with just a few LIFE STYLE changes because that is LESS THAN 1 pound a week. Just eat a little less or buy fat free if you had been buying regular products, stuff like that. You said you don't like to exercise, but it can REALLY help. Escpessially building muscle, I know originally muscle may gain pounds but it's not at all fat plus muscle burns more calories than fat so if you build muscle you will burn more calories while doing nothing. Cardio is best for losing fat though, if you really hate exercise just jog during commercials, or take stairs when you would use the elevateor, just small amounts of exercise through out the day can really add up good luck!
