Getting lean for summer isn’t just about dropping weight—it’s about keeping it off for good.
Popular fitness YouTuber Stephanie Buttermore recently shared her complete fat loss system, breaking down exactly how to shed body fat sustainably and maintain results long-term.
Her approach ditches crash diets and unsustainable restrictions in favor of a methodical, evidence-based strategy.
And the best part? It’s designed to work whether this is your first attempt or you’ve struggled with yo-yo dieting for years.

Understanding Your Starting Point
Before slashing calories or adding hours of cardio, Buttermore emphasizes identifying where you currently stand. She breaks starting points into three “fluffy categories”: very fluffy, medium fluffy, and not very fluffy.
Each category determines how aggressive your approach should be. Those with more body fat to lose can sustain larger deficits, while leaner individuals need gentler approaches to preserve muscle mass.
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
Have you reached your goal weight or your goal body composition? Or are you still in a position mentally and physically to keep pushing?
Setting realistic expectations matters tremendously. Medium fluffy individuals should target 8-12 pounds over 12 weeks, while very fluffy people might lose slightly more. Not very fluffy? A moderate deficit over shorter periods works best.
The Nutrition Foundation
Buttermore’s dietary approach centers on two non-negotiable principles: adequate protein intake and increased fruit and vegetable consumption.
She recommends 0.7 to 1 gram of protein per pound of body weight daily. This range aligns with research supporting muscle maintenance and growth during caloric restriction.
Adding fruits and vegetables to every meal serves multiple purposes:
- Increases food volume without adding excessive calories
- Boosts satiety and reduces hunger
- Provides essential fiber for digestive health
- Helps manage appetite long-term
Calculating Your Calorie Deficit
The magic number starts with maintenance calories—how much you currently eat to maintain your weight. From there, create a deficit based on your weekly weight loss target.
Research suggests losing 0.5-1% of body weight weekly. But for muscle preservation, Buttermore recommends staying around 0.7% weekly loss.
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.

Since one pound of fat equals roughly 3,500 calories, losing one pound weekly requires a 500-calorie daily deficit. Very fluffy individuals can target 1% (approximately 2 pounds weekly), medium fluffy should aim for 0.7%, and not very fluffy around 0.5%.
Movement That Actually Works
Creating your deficit doesn’t mean slashing all calories from food. Strategic movement allows for more flexible eating while still hitting fat loss targets.
Take someone maintaining at 2,500 calories aiming to lose 0.7% weekly. That requires roughly a 350-calorie daily deficit. Eating 2,150 calories achieves this—but adding 5,000 daily steps (burning approximately 170 calories) means eating 2,320 calories instead.
There are no best forms of cardio, only the ones that you can actually stick to.
Walking ranks among the most effective and sustainable options. Buttermore recommends 30-60 minutes daily, which can be split into manageable chunks throughout your day.
Low-impact cardio options include hiking, stair climbing, or any activity you genuinely enjoy. Consistency trumps intensity every time.
Resistance Training Changes Everything
While cardio burns calories, resistance training builds and preserves muscle—the key to avoiding “skinny fat” syndrome. Buttermore strongly advocates starting a lifting routine alongside your fat loss phase.

Beginners should start with either a 3-day full body split or 4-day upper/lower split, depending on schedule constraints. Both options provide adequate stimulus for muscle growth while remaining manageable.
Tracking Progress Beyond The Scale
Consistent tracking separates successful transformations from frustrating plateaus. But scale weight alone doesn’t tell the complete story.
Effective tracking methods include:
- Daily weigh-ins: Take morning weight post-bathroom, calculate weekly averages
- Progress photos: Weekly photos in identical lighting and conditions
- Body measurements: Track waist, arms, thighs, hips, and chest circumference
- Clothing fit: Notice how jeans and shirts fit over time
Women especially should use multiple metrics since hormonal fluctuations can cause 3+ kilogram weight swings during menstrual cycles—completely independent of fat loss progress.
Making Strategic Adjustments
Fat loss isn’t set-and-forget. As body weight decreases, maintenance calories drop proportionally. What worked initially eventually stops producing results.
Consider someone who starts at 150 pounds with 2,500-calorie maintenance. Six weeks later at 143 pounds, maintenance drops to approximately 2,390 calories. That original deficit no longer creates the same weekly loss.

What has actually happened is my initial maintenance, which was 2,500 calories at 150 lb, is now dramatically lower.
Adjustments mean either reducing food intake further or increasing daily movement. Adding 3,000 steps might restore your deficit, or you could reduce calories by 100-150 daily.
Smaller bodies also burn fewer calories during exercise, so movement-based deficits may require additional tweaking. Trial and error becomes part of the process.
Maintaining Results Long-Term
Reaching goal weight represents just half the battle. Maintaining those results separates temporary transformations from permanent lifestyle changes.
Success hinges on habits built during your deficit phase. Protein-focused meals, portion awareness, increased produce consumption, and consistent daily movement shouldn’t disappear after 12 weeks—they become your new normal.
Transitioning to maintenance mirrors the deficit process in reverse. Gradually increase calories or reduce activity until you find your new maintenance range for this lower body weight.
Expect slight weight fluctuations initially. Increased food volume in your digestive system and metabolic adaptation can cause temporary scale spikes. Continue monitoring biofeedback and adjust accordingly.

When Your Goal Weight Isn’t Sustainable
Sometimes reaching your target reveals that maintaining it compromises quality of life. There’s zero shame in settling at a slightly higher weight that feels sustainable long-term.
Remember that your quality of life is much more valuable and important than the definition you have on your midsection.
Vitality should increase through fat loss, not diminish. If maintaining extreme leanness requires unsustainable restriction, finding a comfortable middle ground ensures lasting results.
Taking Action Today
Buttermore’s final advice? Stop researching and start implementing. Pick one strategy from her framework—even imperfectly—and begin immediately.
Fat loss doesn’t require perfection from day one. It demands consistency over time, strategic adjustments when progress stalls, and building habits that match your goal physique.
The difference between another failed attempt and permanent transformation lies in sustainability. Choose aggressive enough deficits to see progress, but gentle enough to maintain muscle, energy, and sanity throughout the process.
Most importantly, remember this isn’t just about summer—it’s about creating a body and lifestyle you can maintain year-round.
