Evidence-Based Fat Loss & GLP-1 Coaching for 6- & 7-Figure Men 30+

A SURMOUNT-1 body-composition substudy examined 160 participants with DXA scans. With tirzepatide, body weight decreased 21.3%, fat mass 33.9%, and lean mass 10.9% over 72 weeks. Roughly 75% of weight lost was fat and 25% was lean mass.

Coach Pauly Takeaway: GLP-1 coaching shouldn’t be about making the scale fall as fast as possible. Nutrition, adequate protein, resistance training and recovery become especially important when the goal is losing fat while preserving as much muscle and function as possible.

In a randomized, double-blind trial of 100 men with obesity and low testosterone undergoing a calorie-restricted weight-loss program, testosterone treatment produced greater fat-mass loss and better preservation/recovery of lean mass than placebo.

Coach Pauly Takeaway: Hormones can influence body composition, but TRT isn’t a substitute for nutrition, training, sleep or weight management. Medication decisions belong with the prescribing clinician; coaching addresses the lifestyle pieces surrounding them.

In a randomized controlled crossover study, participants restricted to four hours of sleep opportunity consumed more calories, gained more weight and accumulated more abdominal—including visceral—fat than during the nine-hour sleep condition.

Coach Pauly Takeaway: Sometimes another diet cut, stimulant or cardio session isn’t the missing piece. Sleep and recovery can materially affect eating behavior and body composition.

A clinical review found that obesity can coexist with micronutrient deficiencies, commonly including vitamin D, iron, folate, B12, calcium, magnesium and others. Restrictive weight-loss diets can potentially worsen nutritional inadequacies.

Coach Pauly Takeaway: Calories and macros don’t tell the entire nutrition story. Food quality, dietary variety and legitimate micronutrient needs matter too—and supplementation should be purposeful rather than random.

A systematic review and meta-analysis found that protein intake above the RDA modestly benefited lean-mass outcomes overall and attenuated lean-mass loss during energy restriction.

Coach Pauly Takeaway: Fat loss isn’t simply “eat as little as possible.” Protein, calories, carbohydrates and fats should be structured around the individual’s goals, training and lifestyle.

Laboratory reference ranges are generally statistical ranges, and this review explains why results outside a reference interval aren’t automatically clinically meaningful—and why interpretation can be affected by testing methods and individual factors.

Coach Pauly Takeaway: Blood work should provide context, not internet diagnoses. I use blood work for educational and coaching purposes to help inform nutrition, training, recovery and lifestyle conversations, while diagnosis and treatment stay with licensed medical professionals.

A 2026 review examined situations in which HbA1c and actual glycemia can disagree, including certain hematologic conditions, kidney disease, biological variation and analytical factors.

Coach Pauly Takeaway: Metabolic health deserves context. Rather than obsessing over one isolated number, relevant biomarkers, body composition, nutrition, activity, sleep and trends over time can all contribute to the bigger picture.

This 2026 systematic review and meta-analysis included 65 studies and approximately 10,000 participants. Behavioral strategies associated with better long-term weight outcomes included goal setting, feedback and self-monitoring.

Coach Pauly Takeaway: The goal isn’t another successful diet followed by another rebound. We want to build the behaviors that allow someone to actually live afterward—restaurants, vacations, weekends, family life and stressful workweeks—without constantly starting over.
