If you have lost weight in the past and gained it back, you KNOW for a fact you can do it again! If you have done it once you CAN do it again, just FOCUS. You KNOW its possible and you can do whatever you set your mind to! Never say Never!
If you have the chance to log your meal or snack right away while you are eating or or directly after, you won't have to try to remember what you ate throughout the day and this way, you are less likely going to forget what you ate when its time to log it in.
To lose weight, the key is to SWEAT! You can do anything as long as it makes you sweat. 30 Minutes of sweating each day will definately help you lose weight. You can clean. dance. exercise, walk...whatever you enjoy, but sweat it off!!
