Losing weight: To lose weight, get ur resting metabolism rate done(weight loss centers do this). This determines the total number of calories you need to lose 1-2lbs/week. Decreasing 500cal/day will give you a 1lb wt loss in 1wk; drink water (1/2 your body weight), eat small meals about 150-200cal 2-4x/(depending on your metabolism rate) and 500cal/meal at night: lean protein/veggies; avoid carbs, .
