Fat loss can feel like a frustrating guessing game.
You’re doing everything right—tracking meals, hitting workouts, staying consistent—yet the scale refuses to budge.
But what if your body was actually sending signals that a breakthrough was just around the corner?
In a recent video, fitness coach Paul Rebello from prophysique.com shared three telltale signs that indicate you’re about to see a significant drop on the scale, based on his extensive experience coaching clients and competing as a bodybuilder at body fat levels as low as 5-6%.

Why Fat Loss Feels So Mentally Exhausting
Rebello emphasizes something most fitness content glosses over: the hardest part of fat loss isn’t physical.
“I often tell people that the hardest part of fat loss is not the physiological stuff. It’s not the diet, it’s not the cardio, it’s not the training,” he explains. “What’s hardest is the psychology of you’re doing all that. You’re nailing it. And then you wake up one day and the scale’s up a pound and you’re like, I want to pull my hair out.”
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
Understanding the signs that progress is imminent can be game-changing for maintaining motivation during these plateaus.
Especially when you don’t have a coach or community supporting you through the mental challenges.
Sign #1: Sudden Mood Changes and Irritability
The first indicator Rebello watches for—particularly as clients approach 10% body fat—is a noticeable shift in mood and energy levels.
When I have a day where I’m just like grumpy, short with people, I’m about to see a big drop on the scale. It’s almost as if my body is saying, ‘Hey, dude, we need to eat more food.’
This phenomenon makes biological sense.
When you’re in a caloric deficit, your body perceives a threat to survival and attempts to trigger behaviors that encourage eating—including mood alterations that might drive you toward food.
Blood sugar fluctuations and hormonal changes contribute to feelings of grumpiness and low energy during deep fat loss phases.

Reframing the Bad Mood Days
Rather than viewing irritability as a problem, Rebello has learned to reinterpret it as a positive signal.
“When I’m in these days where I’m like, ‘Man, I just I’m not in a good mood. I don’t want to be around people.’ It’ll actually get me excited. ‘Wow, I’m about to hit a new low,'” he shares.
This mental reframe transforms a potential diet-ending frustration into evidence that the process is working.
Your body is resisting the breakthrough—which means it’s coming.
Sign #2: Visual Changes Without Scale Movement
As a coach, Rebello focuses heavily on non-scale victories because the number on the scale doesn’t distinguish between fat, muscle, water, and food mass.
He’s noticed a consistent pattern: visual and physical changes often precede major scale drops.
If you want something simple that actually works, this is one of the most effective tools I’ve used to build strength, conditioning, and endurance without needing a full gym setup.
- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
I’ll notice either some of my underwear or my shorts or my shirts just fit a little differently. Likewise, around this time, I’ll also notice some new detail in the mirror.
These subtle shifts might include:
- Clothes fitting looser around the waist or shoulders
- New muscle definition appearing in forearms or abs
- Visible veins that weren’t noticeable before
- Facial features appearing sharper or more defined
The Fat Cell Water Retention Phenomenon
Why do visual changes happen before the scale reflects them?
Rebello explains that even when fat cells release their stored fat, they temporarily hold onto water in its place.
“Fat cells, while they have a reservoir of fat in them, they will also temporarily store a reservoir of water,” he notes. “Even when you’re leaning out and you’re losing body fat and that fat cell has released its reservoir of fat, which would typically mean you lose weight, it will temporarily store some fluid in that fat cell.”
Eventually, your body releases this retained water, resulting in what appears to be a sudden scale drop—though the actual fat loss happened days earlier.
Research on this mechanism is limited, but the phenomenon aligns with well-documented patterns of water retention during caloric restriction, particularly in response to cortisol elevation and glycogen depletion.

Third-Party Feedback
Another validation point comes from external observers who notice changes you might miss.
Rebello recounts viewers commenting that he looked leaner in his videos, even when he didn’t feel different—only to see a two-pound drop the following day.
Others can often see what we can’t because they’re not scrutinizing daily micro-changes.
Sign #3: The “Whoosh Effect” – Increased Urination
The most immediate predictor of an impending scale drop, according to Rebello, is a sudden increase in bathroom trips.
There will come a day where I just cannot stop urinating. Like I haven’t increased my fluid intake, I haven’t decreased my sodium, I haven’t done anything outside of the norm, but I’m literally running to the bathroom every day.
This phenomenon, often called the “whoosh effect” in fitness communities, represents the body’s release of retained water from fat cells.
While the specific “whoosh” mechanism isn’t formally established in scientific literature, the underlying principle is sound: water retention can mask fat loss, and when released, it creates rapid scale changes.

Fat Loss Isn’t Linear
Rebello emphasizes that expecting steady, predictable weight loss is unrealistic.
“In a perfect world for fat loss, we would literally just drop 0.2 lb per day, right? It’s not how it works,” he explains. “Fat loss, your weight is going to be stable, stable, sometimes even up, and then it’s going to be a drop.”
Understanding this pattern prevents panic during plateaus.
A gallon of water weighs eight pounds—fluid fluctuations alone can dramatically affect daily weigh-ins without reflecting actual body composition changes.
Practical Application: Using These Signs to Stay Motivated
Recognizing these three signs creates a powerful psychological advantage during fat loss phases.
Instead of viewing plateaus as failures, you can interpret them as evidence that progress is brewing beneath the surface.

What to Do When You Spot the Signs
- Stay consistent with your nutrition and training plan
- Don’t panic if the scale temporarily increases or stalls
- Track non-scale metrics like progress photos, measurements, and how clothes fit
- Celebrate visual changes even when the scale hasn’t moved
- Trust the process during grumpy, low-energy days
Rebello notes that extreme hunger days often pair with mood changes and similarly signal impending progress.
“When that scale hits a new low it’s amazing how good of a day you’re going to have when you see a number you haven’t seen before,” he observes.
The 12-15% Body Fat Threshold
For men specifically, Rebello highlights that reaching 12-15% body fat is “reasonably easy” compared to pushing into single digits.
At this level, you’ll have visible abs, shoulder definition, and a tighter facial appearance—what most would consider “in shape.”
More importantly, you won’t typically experience negative consequences like hormonal disruption, strength loss, or sleep issues that often accompany deeper cuts.
It’s below this threshold—as you approach 10% and lower—that the psychological and physiological challenges intensify, making awareness of these progress signals especially valuable.

Building Your Support System
Rebello stresses the importance of having people in your corner during fat loss journeys.
“If you don’t have somebody in your corner like a coach, you don’t have somebody in your corner like a community, a group of people that have been through this, that are going through this, then it can be a struggle,” he acknowledges.
Whether through coaching, online communities, or accountability partners, external support structures help you navigate the mental challenges when the scale seems stuck.
These support systems provide perspective during plateaus and celebrate non-scale victories that keep motivation high.
The Bottom Line on Scale Drops
Fat loss is as much a psychological journey as a physical one.
By recognizing the three signs—mood changes, visual improvements without scale movement, and increased urination—you can maintain confidence during inevitable plateaus.

- Full-body training with one weight using swings, squats, and presses
- Solid cast iron build that feels stable and lasts for years
- Comfortable grip that makes high-rep workouts easier to handle
These indicators suggest your body is preparing for what Rebello calls a “breakthrough,” even when daily weigh-ins feel discouraging.
Remember that the scale measures total body mass, not just fat.
Water retention, inflammation, food volume, and muscle changes all influence that number.
Progress is happening even when it’s temporarily invisible.
The key is trusting the process, tracking multiple metrics beyond just weight, and understanding that your body’s resistance signals—grumpiness, stubborn scale readings—often precede the exact progress you’re working toward.
