The best smart scales to track your fat-loss progress
Tracking your performance is an essential part of getting in shape. It keeps you accountable and there’s nothing more satisfying or motivating than seeing progress.
One of the easiest ways to monitor your progress is by taking some basic body composition measurements. As well as calculating your weight, the new generation of best smart scales will also tell you how much body fat and muscle mass you’re carrying. Here’s what you need to know before you step on.
Do I need to track my weight?
Yes – quite simply because it will tell you whether or not you’re making progress. If you’re aiming to reduce body fat levels and you don’t weigh yourself, it is difficult to know if what you’re doing is working. If, on the other hand, you are regularly stepping on the scales, seeing progress can be hugely motivating. The accountability of knowing that you’re going to take a reading will also help you to stick to your training plan.
How often should I weigh myself?
If you’re doing a time-limited programme with a body composition goal, such as the six or eight week New Body Plan programmes, doing a weekly weigh-in will keep you on track. It is, however, important to remember that progress isn’t always linear and you won’t lose fat at the same rate each week. We’d advise against weighing yourself every day because your fluid balance (how much water you’re carrying) and what’s in your digestive system could give you a false impression of where you are.
What best smart scales features are most important?
We’ll assume that the ability to measure your weight is a given. Beyond that, these are the features that will be of most use:
This is useful to know because it is this specific number, rather than your weight, that really matters. For example, you could be ecstatic that you lost half a kilo when really your body fat stayed the same and you were just a bit dehydrated.
Lean Muscle Mass
This is useful to track alongside the number above, particularly if you’re trying to add lean size. For example, you may have gained half a kilo in weight but if that gain was muscle mass, that’s a great result.
This is the fat stored around your organs. It’s a powerful detail because it is this type of body fat that is most harmful to your health. For example, if two people have the same body fat levels but one has significantly higher visceral fat levels then it’s the visceral fat guy who needs to improve his body composition more urgently.
Is Body Mass Index (BMI) data important?
BMI (Body Mass Index) is a very blunt number so it is not that useful. You’re probably familiar with the fact that a lot of lean sportsman would get classified as being overweight because their muscle mass means they weight a lot for their height.
Is Basal Metabolic Rate (BMR) data important?
Basal metabolic rate is also something that sounds useful but, in practice, isn’t necessary to track. The theory is that it tells you how many calories you burn at rest, so you can use it to influence your calorie intake. But if you do that, it means that you have to track your calorie intake and calculate your expenditure through activity. You basically end up doing a lot of calculations that may not even be very accurate because factors such as food quality, digestive health and cooking methods all influence how many calories you consume and burn.
A better strategy is to find a sustainable eating plan and track the measurements we’ve recommended above. If you do that and you lose fat and maintain or gain muscle, that’s great. If you don’t lose fat, you can either increase your activity levels or slightly reduce how much you eat. Essentially you’re looking for the measurements that are of most value rather than feeling like you’re drowning in data.

It also calculates your resting metabolic rate, which is the number of calories your body burns each day without extra activity.

Best for heart health
