Hitting the gym consistently but still fighting stubborn fat? You're not alone. Sarah Mackay knows this struggle all too well. Once a gym-avoider battling an eating disorder, Sarah transformed her life through fitness and now coaches others through similar challenges. "It feels like you're constantly stuck in a loop where you're gaining muscle but not losing fat, so the scale is either staying the same or even going up," Sarah explains in her post. She discovered that body recomposition—building muscle while losing fat simultaneously—requires fixing specific mistakes that sabotage progress. Here's how Sarah finally broke through her plateau.
Mistake 1: Mismatching Diet to Your Experience Level
Your training history should dictate your nutritional approach. "If you're a gym noob or you've been training for up to around two years, you can really get away with eating at maintenance or even in a deficit," Sarah points out. Beginners often make the mistake of "eating big to get big," which leads to unnecessary fat gain. Meanwhile, advanced lifters (5+ years of consistent training) frequently make the opposite mistake. "Unfortunately for you guys, you really can't bulk like you used to," Sarah says. She recommends veterans stick to eating at maintenance or in a slight deficit, losing around 0.7 percent of body weight weekly for optimal recomposition.

Sarah found that her body composition dramatically affected her recomposition strategy. "People who start out leaner at around sub 10 body fat for men or sub 20 for women will have a much harder time building muscle and losing fat simultaneously," she explains. This happens because lean individuals have fewer fat reserves to fuel muscle building. Conversely, those with higher body fat percentages have more energy stored and achieve recomposition more readily. "People who are overweight at their baseline have so much more energy reserved," Sarah notes, explaining why they can successfully build muscle in a moderate deficit.
Mistake 3: Neglecting Protein and Food Quality
Even with perfect calories, Sarah discovered her macronutrients were holding her back. "Research has shown that higher protein diets, about 1.2 grams per pound of your body weight, can improve your body composition by reducing fat mass and increasing fat-free mass," she shares. For most people, aiming for around 1 gram of protein per pound of body weight daily maximizes muscle growth while supporting fat loss.
Beyond macros, food quality matters tremendously. "When you consume foods that don't sit well with your body or your digestion, your body becomes inflamed and you hold onto water weight," Sarah reveals from personal experience. This water retention is easily mistaken for stubborn fat. "What has personally helped me is focusing on eating mostly single-ingredient foods, also focusing on getting in enough fiber, around 30 grams every single day," she explains. Sarah learned to pay attention to how different foods affected her energy, digestion, and overall well-being.
Mistake 4: Compromising on Recovery
Surprisingly, Sarah's overtraining was sabotaging her fat loss efforts. "Muscle actually doesn't grow if you're not giving it the time to recover," she cautions. This means both taking 1-2 weekly rest days and prioritizing sleep. "Research has shown that when two groups follow the same calorie deficit but one group sleeps just three hours less each week, both groups lose similar amounts of weight, but in the well-rested group 83% of the weight loss is from fat compared to only 58% in the sleep restricted group," Sarah explains. She aims for at least 7 hours of quality sleep each night to optimize her body's fat-burning potential.

During Sarah's recomposition journey, she realized the scale was misleading her. "Despite what nonsense you have been fed from your mum's favourite magazine, weight gain is not just the product of fat gain but also includes muscle gain and water gain too," Sarah points out. She learned to track multiple metrics: progress photos, measurements, how clothes fit, strength gains, and energy levels. "The scale can be used as a great tool in order to see if you're going in the right direction, if you're eating in a deficit or in a surplus, but that is exactly what it is—a tool that should be used in conjunction with other tools," she emphasizes.
Understanding the Timeline
Perhaps the biggest revelation for Sarah was accepting that body recomposition takes considerable time. "Pound for pound, fat is easier to lose than muscle is to gain," she explains. You might be losing fat already but need more muscle development to achieve that toned look. "9 to 12 months is a realistic goal in order to see results using this process," Sarah advises. She embraced the process as a sustainable lifestyle change rather than a quick fix, which finally allowed her to break through plateaus and achieve lasting results.
Progressive Training Is Essential
While fixing nutritional mistakes gets most attention, Sarah discovered that proper training progression remained fundamental. "Track your sets, reps, and weight during each workout and try to increase the weight you're doing or the amount of reps over time," she recommends. Following the same workout routine for 8-12 weeks while focusing on gradually increasing performance gave each muscle group sufficient stimulus to grow while her improved recovery allowed fat loss to continue.

Developing body awareness accelerated Sarah's progress significantly. "When you eat something, think to yourself: how do you feel? Are you digesting this food well? Does it give you brain fog?" she suggests. These feedback signals helped her identify which foods supported her goals and which ones caused inflammation or energy crashes. The same principle applied to workout intensity—pushing hard, but recognizing when her body genuinely needed rest proved crucial to breaking through her plateau.
