Before anyone jumps down my throat, yes, I know well that to lose weight you have to be in a calorie deficit - eating less calories than you burn.
However, anyone who's followed a diet will notice that consuming less food can often result in lower energy levels throughout the day, negatively affecting our mood and most importantly, our activity levels.
NEAT (non-exercise activity thermogenesis)
Represents all the physical activity throughout the day that isn't considered exercise - walking, fidgeting around, work, etc. When you restrict calorie intake, it can cause you to move less outside of the gym in your daily life. This decrease in NEAT can ultimately cause your fat loss to plateau. Although this is doesn't happen 100% of the time, it's smart to and monitor your physical activity using a basic activity tracker like the FitBit for example and see if your activity levels drop when dieting. It's also smart to be more aware of your mood from day to day and how it affects your motivation levels and your ability to get up and move.
I've written in detail about NEAT and daily calorie expenditure, what they are, and how to use it to your advantage to help your weight loss and fitness goals. Click here to read.
I am in no way advocating for ridiculously high calorie intakes and trying to catch up on your weight loss by performing hours upon hours of exercise. Most people do not have the time nor energy to do so. What I'm advocating for matching the positive mood and motivation levels that comes with a more moderate calorie intake, with higher NEAT levels throughout the day.
If you feel groggy and unmotivated eating 2000 calories a day, it may be smart to increase it to 2250 or a number you'll feel more comfortable or happier at. From here reach a calorie deficit by an extra 5000 steps a day or by staying more active outside of the gym.
Go for a walk on the beach. Go for a bike ride. Move more around the house. Keep yourself active, but keep it simple. The main goal here to is develop a more active lifestyle and making small tweaks to our diet to better accomodate it. Hope it helps!
