I’m sure we’ve all watched Operation Transformation at some point, right? Karl Henry and his sidekicks making 2Joe Ordinary” feel guilty for not losing their target weight or gaining 1lb in weight over the course of a week while we all look on disappointed for him/her. The trainers then increase the intensity of their exercise program the following week to get them back on track and possibly lower their calorie intake too.  The short video clip see’s the experts lambasting Eilish despite her loss that week.

The problem with using just your bodyweight to measure success with an exercise program or a new diet plan is that it only tells part of the story. Your weight is just one piece of the jigsaw. You need all the pieces to see the full picture. Curious? Great! Read on…….



When a client tells to me that they want to lose weight, in my head I know what they really mean is they want to lose FAT. Ask yourself if that’s true for you if shedding a few pounds is your goal? If a client loses 1lb of fat but gains 1lb of muscle their weight will stay the same but they have made a healthy change, haven’t they?

Seeing the number on the scales stay the same or increase can be frustrating, disheartening and demotivational for somebody trying to lose weight. DON’T LOSE HEART! There are so many reasons the number on the scales won’t change. They include (but are not limited to):

  • Hydration Levels

If you are dehydrated you will weigh less than when fully hydrated as you have more water in your body. You will weigh less after an intense workout or a trip to the sauna as you sweat out your water weight. As soon as you drink again it will re-appear on the scale.

  • Hormone Regulation

The stress hormone cortisol can trigger fat gain1. Stress can be caused by physical, emotional or physiological factors such as illness or lack of sleep. Physical and psychological stresses can also cause a lack of sleep leading to stress causing a vicious cycle.

  • Nutrition

I’ve heard of people fasting the day of a weigh in!!! Sure, a belly full of Spag Bol will add weight but it won’t immediately increase your body fat! Restricting calories for fear of being heavier on a scale in the equivalent of not putting petrol in your car for fear it will make you slower.

  • Muscle Mass

Loss or gain of muscle mass will affect weight but a drop in weight due to a loss of muscle mass is a red flag and you should speak with your trainer if this is happening. Periods of inactivity caused by illness or injury can cause muscle wastage BUT once back training it can return. Also it’s not unusual for muscle mass to slightly reduce while trying to lose fat due to a slight decrease in calories.

  • Illness

Lack of appetite, vomiting, dehydration and inactivity will lead to weight loss for numerous reasons but that doesn’t mean the weight lost during a bout of flu is a good thing. You may lose muscle mass due to inactivity, water weight via sweating or simply a lack of stomach contents. I’ll allow your imagination run wild with that thought.


There are more reliable measures for fat loss (notice how I didn’t say weight loss) than the weighing scales and these include body fat testing and anatomical measurements.

  • Body Fat Testing

The table below shows the recommended body fat percentages for men and women and can be found here: or simply save this picture by right clicking and “save as”.


Having a skinfold caliper test performed can tell you how much fat your body has stored. A woman weighing 100kg with a body fat of 20% will have 80kg of lean tissue. If in 8 weeks you still weigh 100kg but have a body fat of 15% you KNOW that you have reduced fat and increased muscle mass. A good result all round! This short video demonstrates a skinfold caliper test.

  • Anatomical Measurements

Waist MeasurePicture:

Have a gym instructor, a friend or even take the measurements yourself. All you need is a soft tape measure! Measure your waist (in line with the bellybutton), your hips (at their widest part – generally the widest part of your bum) and your upper arms (half way between the shoulder and elbow – no flexing). If you gain or maintain weight but are losing inches you know you are making progress! Don’t be disheartened by the scales, remember it’s only PART of the big picture.


Don’t just use your weight to determine whether or not positive body composition changes are happening because, frankly, it’s unreliable. Get your body fat tested. Get your measurements recorded. Take some progress pictures every 4-6 weeks. Get all the pieces of the jigsaw together and you may see that the overall picture is more positive than one piece is letting on.

Remember that once you begin any new physical activity that fat loss is not the only positive change that will occur. Your sleep quality will improve, your energy levels will be boosted, your confidence and self-esteem may improve, your mood may improve and your food choices may become healthier to compliment your exercise regime. That’s a lot of good stuff!! Stay positive, keep consistent and positive body fat changes will happen. Trust me!
