Do not damage your body, emotionally or physically, as this can lead to failure for your weight loss. If you have an injury, it's okay to slow down. Find an alternative exercise that you can do easily, while the injury heals. If you are mentally blocked, figure out why. It's okay to take a break if you need to.
Some of the simplest things can help you lose weight, such as using a smaller plate when eating. As simple and silly as this trick may sound, research has shown that it truly works. Since a smaller plate looks full with a smaller portion, a person eats less each meal. Since a person has a tendency to eat everything on their plate, less food is consumed; however, the mind is tricked into relaying a message of satiety to the stomach, since the plate has been cleaned of all food.
