Weight Loss VS Fat Loss: The Difference 2021

When it comes to losing weight many people often only focus on a single metric which is usually that number on the scales. Although this trend seems to be changing, with the ever-increasing information we have access to, People will still judge their progress solely on whether the number on scale decreases on a weekly or sometimes daily. Both approaches are not wise. Let us discuss why this is a bad strategy from the start then. Every single piece of tissue (muscle, fat brain, liver, bones, kidneys) and everything in-between weighs something. So, when you step on the scales that number represents your “total body weight”.

Obviously, the number itself cannot distinguish between how much of that total body weight is fat tissue versus muscle tissues versus everything else. Hopefully, now you can start to see why using the scales as the sole predictor of is problematic from the outset. For this reason, it is much better to determine how much of your total body weight is actually fat tissue. Everything else leftover is called your lean body mass (LBM). We can do this several ways with some having more accuracy than others (Bodpods, Tanita scales, hand-held devices, calipers, dual-energy x-ray absorptiometry, hydrostatic weighing).

Regardless of which one you choose, choosing any is better than that not choosing any at all as you will get a better picture of your progress. For example, let’s say you have two people who start outweighing 220 pounds and lose twenty pounds over the course of a few months. Let us call them Person A and Person B. Along with checking their weight on the scales that confirm they’re now 200 pounds, Person uses one of the above body fat analysis techniques which displays they are now 30% body-fat. This means out of that 200 pounds, 140 pound is LBM (200 * .30 = 60, 200 – 60 = 140). Person B does the same thing but while their weight is the same as person A, their body fat is 10%. This means out of the 200 pounds, 180 pounds is LBM (200 * .10 = 20, 200 – 20 = 180).

In this scenario, Person B is a lot “healthier” as they are carrying less fat tissue, which means less fat tissue around vital organs like the lungs and heart and less risk when it comes to developing diseases like coronary heart disease and diabetes. Not only this but the person with the greater LBM has greater metabolic turnover meaning because they have more muscle, they have high metabolic rate than some person A. This is because muscle burns a lot more energy than fat while at rest.

Finally, there will be weight fluctuations of a few pounds give or take on a daily basis. This is down to several factors including the food you eat, the amount of fluid you drink to the amount of stress you’re under. Therefore, using a “weekly weigh-in” solely will not

tell the whole story. Let’s take food for example, in particular carbohydrates, for every 1 gram of carbs, your body holds approximately 3 grams of water so when carbs are dropped a lot of water leaves the body.

The average person will store about 500g of glycogen in muscles and 100g in the liver, that would be 1600g (3g x 600g) of stored water eliminated also (3-4 pounds) if someone drops the carbs for a day or two. Can you see why people gravitate to the whole “it must be the carbs that were making me put on weight now”? They get instant success when they drop them but in fact, most of that is in water (if not all). This also works the other way as soon as carbs are reintroduced water retention occurs at a rapid rate thus total body weight increase. So, if someone eats more carbohydrates (pastas, breads, rice etc.) close to their weigh-in day or drops them before for 24-48 hours before it, their weight essentially can be manipulated by a few pounds.

Now of course we’re not saying that the scales are lying per SE, we’re saying it may not be telling the whole story. Therefore, using more than one measure to track weight loss progress is important such as tracking your body-fat percentage, waist circumference and so on. Certainly, losing weight and building some lean muscle along the way is far better than just losing weight by just eating very little.

As you can see it is important to know not just the differences between weight loss and is but also know what may cause these differences in advance of setting out on your weight loss journey.
