He Lost 100+ Pounds and Would Do It Completely Differently. Thomas DeLauer Reveals 14 Brutal Truths He Wishes He Knew at 300 Pounds

Dropping over 100 pounds is no small feat — but what if you had a chance to do it again, armed with the knowledge you have now?

In a candid reflection, fitness and nutrition expert Thomas DeLauer looks back on his transformation journey and shares the tactical strategies and emotional lessons he’d apply if he could talk to his 300-pound self today.

With nearly two decades of insight, hard-won experience, and updated scientific research, he outlines what helped, what hindered, and what he wishes he had done differently — from collagen to mustard and from emotional healing to electrolyte use.

If you’re looking to lose weight, avoid metabolic setbacks, or simply improve your overall wellness in a sustainable, balanced way, this real-talk roadmap could save you years of trial and error.

1. Prioritize Joint Support Early On

One of DeLauer’s biggest regrets? Not using collagen protein during the early, intense phase of his weight loss.

“At 300 pounds, I pounded my joints with running and high-impact workouts,” he shares. “Collagen could’ve preserved some joint integrity.”

Back then, collagen was dismissed as just another amino acid source. Today, studies show collagen can support joint health, recovery, and skin elasticity, especially in overweight individuals with high physical stress. For those starting their weight loss with intense workouts, incorporating collagen may help mitigate long-term wear and tear.

2. Train Both Fasted and Fed

Fasted workouts helped DeLauer torch fat, but relying solely on them brought unintended consequences.

“I trained fasted so much that afternoon or evening workouts felt impossible,” he explains.

Today, he recommends flexible training states. While fasted workouts still serve as a powerful fat-burning tool, feeding before some sessions helps build metabolic adaptability — and avoids missed workouts due to poor energy from rigid routines.

3. Use Mustard as an Appetite Hack

Sounds odd, but DeLauer now swears by mustard for appetite control thanks to its effect on TRPV1 receptors, which influence satiety.

“I should’ve drowned more meals in mustard,” he jokes. “It curbs cravings and could’ve made things a lot easier.”

Unlike many diet fads, this biohack has some promising data — the capsaicin analogs in mustard offer thermogenic and appetite-modulating benefits.

4. Heal the Emotional Side Sooner

Though known for data-heavy content, DeLauer admits one of the most “life-altering” changes came from addressing his emotional health.

“If I had dealt with my demons earlier, I would’ve avoided a lot of obsessive behavior, body dysmorphia, and stress-driven decisions,” he reflects.

Mindset matters. Dieting from a place of fear can lead to burnout. Healing the root causes of unhealthy habits offers clearer thinking, long-term consistency, and improved self-image.

5. Prioritize Gut and Immune Support

Weight loss can tax your immune system — something DeLauer discovered the hard way.

He now uses glutamine and bone broth to repair gut lining and improve immune function during intense training or calorie restriction. Glutamine feeds enterocytes, the cells lining the gut wall, and can reduce illness during phases of hard dieting.

6. Eat More, Move More — Don’t Starve Your Metabolism

Early in his journey, DeLauer often chose to eat less and move less — a combination that slows metabolic rate.

“I would have reversed that thinking — eat more and move more,” he advises. “Keep metabolism high and reduce the likelihood of long-term metabolic damage.”

7. Don’t Fast Every Single Day

Intermittent fasting was key to his weight loss, but daily fasting without breaks ended up hurting more than it helped.

“I fasted too consistently and crashed my metabolism,” he says. Now, he advocates for 2–3 longer fasts per week instead of daily intermittent fasting, especially early on. This allows hormonal and metabolic systems time to recover.

8. Use Salt and Electrolytes Strategically

Cravings don’t always mean you’re hungry. Sometimes, they’re signaling electrolyte deficiencies, especially sodium. DeLauer discovered salt could suppress his sweet tooth and stabilize appetite.

Now, he uses electrolyte supplements and consumes more salt during fasts or workouts, improving appetite control, mental clarity, and muscle function.

9. Accept Bro Science When It Works

“Evidence is great,” DeLauer says, “but lived experience shouldn’t be ignored.” In the past, he scoffed at anecdotal “bro science.” Now? He respects tools that work — even without double-blind studies to prove them.

“If it works for you and helps you stay on track, use it.”

10. Carb Cycle Instead of Demonizing Carbs

DeLauer went strict low-carb for long periods, but in hindsight, he would have cycled carbs more strategically — low-carb on most days, high-carb refeed days for recovery and metabolic balance.

“Not every day needs carbs. But you do need them periodically — and they can help your thyroid and hormonal function.”

11. Sleep Apart, Stay Together

One unconventional tactic? Sleep divorce.

Sleeping in separate rooms dramatically improved his sleep quality — and his relationship.

“Better rest made me a better husband and human,” he explains. “I wish I had ditched the ego around sleeping arrangements much earlier.”

12. Reverse Diet Every 8 Weeks

To avoid metabolic adaptation, he now recommends a two-week refeed after every eight weeks of calorie restriction. This brief return to maintenance calories helps restore hormones, reduce diet fatigue, and avoid long-term damage.

13. Ditch Cheat Meals for Strategic Refeeds

Cheat meals were part of his early strategy — until he realized they caused wild energy crashes, regret, and undone progress.

“Blowing 4,000 calories on curly fries erased everything I’d worked for that week,” he warns.

Instead, use targeted refeeds with whole foods. These provide the same psychological relief without derailing your progress.

14. Embrace Natural Superfoods Like Bee Pollen and Honey

Bee pollen and raw honey became DeLauer’s unsung heroes when he needed nutrient-dense options in minimal quantities.

• Bee pollen: Rich in multivitamins, quercetin, and antioxidants
• Raw honey: Helps with fat loss, boosts immunity, and reduces inflammation

“I was so afraid of sugar that I missed out on some powerful foods,” he admits. “These ingredients gave me nutritional density without junk.”

The Bottom Line: It’s Not Just the Science — It’s the Soul

If DeLauer could speak to his old self, his message would be simple:

“It’s going to be okay. You don’t need to become a robot. Use science. Heal emotionally. Trust what works. And do it your way.”

Losing weight isn’t just about cutting calories or crushing workouts. It’s a blend of biology, psychology, and lifestyle alignment. With a better understanding of one’s body, mind, and habits, sustainable success becomes less about obsession — and more about flow.

Whether you’re just starting or refining your approach, these lessons offer a roadmap — one built on years of trials, triumphs, and transformation.
