Daily fat loss has an upper limit.
So what happens, then, if your caloric deficit is greater than the amount of fat you can lose in a day?
Are you sure you wanna know? It's not good.
Last chance to close this email and be none-the-wiser.
Ok, you got it ....
What happens is you lose lean (non-fat) tissue. You lose muscle, bone density, mitochondria. Your organs shrink. You lose brain mass. Say goodbye to some of your collagen.
The law of thermodynamics is strong with us. Eat less than you use up and you'll lose. Eat more than you use up and you'll gain. But that used to be where it ended. Now we know there's nuance. WHAT, exactly, are you losing? WHAT, exactly, are you gaining?
Most people lose a mixed bag (some fat but lots of muscle and other lean tissue) but when they gain some or all of it back, it's almost entirely fat. This is usually NOT the desired intent or even something they were aware of!
So how much fat can you actually lose each day???
It depends. It depends on your size and current body composition / body fat percentage. It depends also on whether or not you're maximizing fat loss potential through all the things I talk about here in my weekly newsletters and over on instagram. For example, someone who has better blood sugar balance will be able to maximize daily fat loss potential, moreso than someone whose blood sugar is riddled with spikes and crashes. They are more of a "fat burner". Similarly, someone who is barely getting any sleep and not working on stress management will be more of a "sugar / carb burner" and will tend to lose a greater percentage of their weight as lean mass rather than excess body fat.
But I can tell you this ... it's not a lot and probably less than you'd like. That means the process should be slow. If it's fast, you're likely losing lots of precious lean mass (like muscle) and will be actually priming your body for a greater body fat percentage over time.
So, fast weight loss isn't just not advised. It's not the fat loss that most people think they're getting! And it sets our body up for MORE fat gain and worsened metabolic health (chronic diseases) down the line.
To give some more context, if you're losing 5 lbs in a week or something, you're almost definitely blowing wayyyy past your maximum daily fat loss and burning through precious lean mass. Even less (2, 3, 4 lbs a week) can be problematic. Too fast and that's where damage is done.
Little caveat ... sometimes, especially in the beginning of some lifestyle changes, inflammatory water retention starts to go away. In this case the pounds might come off faster as a result of that process. That's not a problem and will be temporary.
Example: Person A has fast weight loss. Person B has slow weight loss (with attention to detail like strength training, protein, sleep, blood sugar control). Person B is almost always losing MORE fat than Person A, even though society will tell you otherwise. *Eye roll*
If fat loss is a goal of yours, keep this in mind!

P.S. This Friday will start the Early Black Friday deal for TRANSFORM: Body + Mind, my 28-day metabolism-boosting course. We cover all the bases (nutrition, fitness, lifestyle) that will help you maximize your daily fat loss potential as well as focus on health optimization so you feel incredible all the while. <3 Enrollment will be open for just a few days because on actual Black Friday I will be decorating my house with the fam and making our traditional Christmas loops. So, I'm closing the cart before Thanksgiving. ;-) Here's how it'll work: if you enroll between 11/17 and 11/21, you'll be in for the upcoming January round.
