Don't give up! I was once over 300 lbs. myself. I was able to shed the weight myself and lost over 140 lbs., but my weight fluctuates. You will hit plateaus that will discourage you to give up, but don't. If you need moral support and encouragement, I am here for you! Diet is key, and cutting carbs and eating more protein is the main thing as carbs turn into sugar. If you can keep your carb count to 100 grams or less, that was ideal for me. Good for you for trying to lead a healthier life!
