I'm not saying that you are not to eat the Oreos. I love Oreos. I love ice cream. But are you properly tracking those, or is it just becoming something that is more of an emotional coping mechanism? - Nathalia

Welcome to another episode of the Unfiltered Fit Life podcast. I’m Nathalia Melo, and today we’re talking about the Big Three: sleep, stress, and hormones—the biggest influencers of fat loss and fat gain.

Why I’m Talking About This Now
Nathalia [00:03:36]
After surveying women at a presentation for a top AM100 law firm, a common pattern emerged: sleep, stress, and hormones were major concerns. This episode is here to simplify those issues and help you regain control over your results.
Energy Balance 101
Nathalia [00:07:52]
Fat loss comes down to energy balance: calories in vs. calories out (CICO).
-
Deficit = Fat Loss
-
Surplus = Fat Gain
-
Maintenance = Balance
Important Note: Stress, sleep, and hormones don’t break the laws of thermodynamics. They influence how we behave—our cravings, movement, hunger cues—not the math itself.
Part 1: Sleep—The Silent Saboteur
Nathalia [00:10:20]
Poor sleep impacts fat loss by:
-
Disrupting hunger (ghrelin) and fullness (leptin) hormone
-
Making you more lethargic (less movement = fewer calories out)
-
Increasing emotional eating
-
Reducing recovery and increasing inflammation/water retention
Action Steps:
-
Build a bedtime routine
-
Hit step goals
-
Track sneaky bites (BLTs = bites, licks, tastes)
-
Be extra intentional with food and movement during poor sleep phases
Part 2: Stress—The Undercover Saboteur
Nathalia [00:17:05]
Stress can sabotage fat loss by:
-
Leading to skipped meals → binge eating later
-
Increasing cravings and emotional eating
-
Raising cortisol levels → more fat stored in the belly
-
Disrupting sleep
-
Making workouts the first thing to fall off
Action Steps:
-
Shift workouts to the morning (even short ones count!)
-
Plan meals ahead to reduce decision fatigue
-
Outsource where needed (meal delivery, house help)
-
Reduce workout frequency if needed—consistency > perfection
Part 3: Hormones—The Blamed One
Nathalia [00:26:43]
Hormonal shifts (especially around menopause) can cause:
-
More cravings and hunger
-
Poor sleep → more inflammation
-
Mood swings, brain fog, and reduced motivation
-
Lower physical activity
-
More body fat, especially around the midsection
Action Steps:
-
Keep training (even when unmotivated!)
-
Prioritize strength training for symptom relief
-
Track symptoms and bring them to your healthcare provider
-
Stick to simple habits like walking, portion control, and food prep
Putting It All Together: Regain Your Agency
Nathalia [00:34:19]
You don’t have to be perfect, but you do need to be intentional.
Start by tracking and noticing patterns:
-
Are cravings up?
-
Are you skipping meals?
-
Are you moving less than usual?
-
Are you blaming hormones when habits are the issue?
Real-Life Example: Cindy’s Transformation
Nathalia [00:40:16]
Cindy, a 61-year-old client, was training 7 days a week and eating too little. After reducing her workouts and increasing calories to support recovery, her body responded positively—more energy, better sleep, and weight loss.
