Hi fumin,
Thanks for writing and welcome to alli! You should be very proud that you've made the decision to be healthy once and for all! With a low-fat, nutrient dense diet, regular exercise and the help of alli, you should see positive results!
I would definitely encourage you to watch you caloric intake with "extras" or empty calories such as alcohol. You are right that it can pack on the pounds, and typically you eat less healthy foods and more of it when you're drinking. Alcohol in and of itself is not bad for you... in fact research has shown that in moderation, it can be good for you. However, until you have your weight under control and are on the way to making progress, I would do my best to abstain from it or keep it to a maximum of 1-2 drinks on that night!
Additionally, incorporating regular, structured exercise into most days of the week is critical in the long-term success of your weight loss! Ideally, you should be getting in 30-60+ minutes of exercise per day. This would include cardio (walking, jogging, swimming, water aerobics, biking, hiking, dancing, tennis, etc.) as well as strength training! The alli website provides helpful ideas and animated demos (for ST) under "my activity." One pound of fat is = to 3,500 calories. Therefore, in order to lose 1 pound of fat per week (7 days) you'll need to create a caloric deficit of 500 calories per day. You can do this by cutting calories in your diet and by burning extra calories through exercise! Exercise also promotes fat loss and builds lean muscle mass. By reducing body fat and increasing muscle, you'll become metabolically more efficient as muscle requires more energy to function than fat! In other words the more lean muscle you have, the more calories you'll burn all day long.... even at rest!
Stay committed, work hard and stay positive! I strongly encourage you to stay plugged into the alli community by regularly posting messages on all of the alli circles! The forums are here to support, encourage, educate you and to keep you connected to other allli customers.
Best of luck and please keep me posted with your progress!
Your friend in fitness,
Kelli
