Elderly Couple Walking on Beach
If you get 10,000 steps per day, you are doing great, and I am sure you will be more fit anything. If you do not, this does not necessarily make you unfit or more likely to be fat. You have to individualize your diet and exercise program. Some will be able to get by with 5000 steps and others will need 20K to keep their weight down. I would focus more on minutes fo exercise. The fact is that most experts recommend tracking the total amount of time you’re physically active instead of the number of steps you take. I suggest 150 minutes of moderate to vigorous aerobic activity per week.
Steps are still a decent measure to help prevent a sedentary lifestyle. Although I think that minutes of exercise is more important, it is not a key measurement of weight loss and fitness. It is a good measure to prevent being sedentary, but it will not keep you slim by itself. You need to add dietary control and discipline and I am not talking about grounding or spanking.
The bottom line: Ten-thousand steps can be a goal but it is not the key to a healthy weight. I suggest that you track minutes of exercise and dietary intake instead of or including steps. Eating a well-balanced diet that is full of whole foods and less processed ingredients is also an important part of any weight loss plan.
