"You can't get rid of it with exercise alone. You can do the most vigorous exercise and only burn up 300 calories in an hour. If you've got fat on your body, the exercise firms and tones the muscles. But when you use that tape measure, what makes it bigger? It's the fat!"

This quote by Jack LaLanne is emphasizing the value of diet plan in addition to exercise when it comes to losing weight. Workout alone is inadequate to eliminate fat. Even if you do the most energetic exercise, you can just burn up 300 calories in an hour. Exercise can help to firm and tone the muscles, however it will not make the measuring tape smaller. The only thing that can reduce the size of the tape measure is decreasing the fat on your body, which can just be done through diet. LaLanne is emphasizing that diet and workout should work together in order to attain weight loss.
