Mind Pump: Raw Fitness Truth
Episode 2690: The NEW DIET Everyone Is Using For Fat Loss
Date: September 22, 2025
Hosts: Sal Di Stefano, Adam Schafer, Justin Andrews, Doug Egge
Episode Overview
In this episode, the Mind Pump crew dives deep into the concept of reverse dieting—a strategy that challenges the conventional "eat less, move more" mentality for fat loss. They explore its origins in physique and bodybuilding, how chronic dieting can slow down metabolism, and why a strategic increase in food intake and strength training might be the key for sustainable fat loss and metabolic health. The hosts provide science-backed insights, practical steps, and personal experiences, addressing the fears and confusion around eating more and losing fat.
Key Discussion Points and Insights
1. What Is Reverse Dieting?
- Definition: Reverse dieting is the process of slowly increasing your caloric intake after a prolonged caloric deficit or chronic dieting, primarily to speed up metabolism and set the stage for further fat loss.
- Origins: Started in the competitive bodybuilding and physique world to help athletes recover metabolically after extreme competition diets ([02:59] Sal).
- Misconceptions: Many see adding calories as counterintuitive for fat loss.
“Add calories, lose body fat. What?” — Adam Schafer [02:54]
2. Why Is Reverse Dieting Necessary?
- Chronic Dieting Leads to Plateaus: The body adapts to persistent calorie deficits by slowing down metabolism.
“You’re consuming 1,700 calories a day, and you’re not losing any weight, which means you’re at what’s called maintenance... Where do you go?” — Sal Di Stefano [06:08]
- The Real Client Struggle: Many clients, often women, come to trainers already eating very little and exercising a lot, yet still unable to lose weight.
- Not Just "Underreporting" Calories: Fitness industry often blames stalled progress on clients underestimating intake, but the issue is often metabolic adaptation.
“Our bodies are so resilient and so smart… it will learn to survive off that.” — Adam [11:29]
3. Metabolic Adaptation and the Problem With Typical Dieting
- Metabolic Flexibility: The body can drastically lower its calorie requirements. Studies, historical examples (POWs), and “The Biggest Loser” show contestants illustrate this.
- The Floor of Dieting: “How far can this number go down? Very far… the body can really slow its metabolic rate down.” — Sal [16:25]
4. Reverse Dieting Goals
- Build muscle (metabolically active tissue)
- Speed up metabolism
- Set up a successful and comfortable calorie deficit (cut) later
“The goal of a reverse diet is to build muscle, speed up the metabolism, and then… set up a successful cut.” — Sal [15:12]
5. How to Implement a Reverse Diet
A. Exercise Focus: Strength Training
- “You have to immerse yourself in the environment that demands to build muscle … nothing better than actual strength training.” — Justin [19:22]
- Traditional strength training (2-3x/week, compound lifts, focus on progressive overload, proper rest between sets).
B. Track Your Baseline
- First Step: Track existing calorie and food intake for 1-2 weeks, no changes yet ([21:00] Sal).
C. Increasing Calories
- Incremental Approach:
- “Typically, people will bump their calories between 1 to 250 per week or two. So every two weeks or so, increase… about 100 to 200 calories” — Sal [21:35]
- If calories are very low, may go up by 500-800 at first.
- Protein Target:
- “A gram of protein per pound of body weight.” — Sal [22:18]
- Hitting protein is non-negotiable to ensure gains are muscle, not fat ([28:13] Adam).
D. Adjust Volume and Intensity
- Avoid doing “more of everything.” Often, less cardio/high activity is better to create room for muscular adaptation ([23:50] Justin/Adam).
E. Focus on Strength Metrics, Not the Scale
- Track Progress via Strength: Improvements in the gym are the best indicator that metabolism is recovering and muscle is building.
- Avoid Weighing: “I don’t let my clients who are reverse dieting weigh themselves. It messes with their head... So I’m like, we’re not weighing yourself at all, we’re just going to track your strength.” — Sal [24:33]
- Small scale increases don’t necessarily mean fat is gained—often water or glycogen shifts.
F. Timeline and Signs of Success
- Typical Duration: 30–90 days, sometimes 6+ months for chronic dieters ([26:14] Sal).
- Indicators for Cutting: When you’re eating a comfortable, “high” amount (usually where food feels abundant) and still progressing in strength, then consider a calorie cut ([27:53] Sal).
Notable Quotes & Moments
- “You’re not, not under-eating, you’re under-reporting. …No, there’s more going on here. The answer for that client is not cutting calories. It’s actually feeding the body more of what it needs and focusing on building muscle.” — Adam Schafer [12:20]
- “When your body’s stressed out, it tries to hold on to body fat. …so if you’re over-stressed, it wants to keep body fat on the body and it doesn’t really want to build muscle.” — Sal (relating an early trainer story) [13:30]
- “Back in the day, a reverse diet would be called a bulk… but really what it is, is you’re eating more calories in a strategic way to add lean muscle tissue, metabolically active muscle.” — Sal [15:12]
- “The body can really slow its metabolic rate down. And this is what you do to yourself through chronic dieting, chronic overtraining. …This is when we reverse diet.” — Sal [16:25]
- “The goal is to reverse diet… not worry about the scale right now.” — Adam [20:24]
- “If you increase calories and those calories come from carbohydrates and fat and you miss protein consistently, this is a recipe for you potentially putting on body fat. …If our calories come from protein… we are far more likely for those additional calories to get partitioned over to building muscle than being stored as body fat.” — Adam [28:13]
- “Always reverse diet. I would start here. And really what it was, was build first, then lose later because the muscle makes the fat loss a lot easier.” — Sal [28:51]
