The Drop Set – Episode 134: Intermittent Fasting, Unsolicited Advice, Meal Replacement Options

Contest prep doesn’t just change your body, it changes how your brain functions day to day.

As calories come down and fatigue accumulates, your body reallocates resources toward survival and performance. Cognitive sharpness, emotional regulation, and stress tolerance often take a hit. None of this is a sign that prep is failing – rather It’s a predictable response to prolonged energy restriction paired with high training demands.

None of this means prep is failing.
It means prep is working — and asking a lot from the system.

Where competitors get into trouble is assuming these mental shifts are problems that need fixing instead of normal adaptations that need managing.

Energy Allocation and Cognitive Load

Your brain is one of the most energy-demanding organs in your body. When food intake drops for weeks (or months) at a time, the body gets selective about where resources go. Thinking clearly, regulating emotions, and tolerating stress all cost energy.  In a deficit, your body falls into “ain’t nobody got time for that” mode.

That’s why prep often feels mentally “heavier” even if nothing dramatic has changed. Tasks take more effort. Small decisions feel annoying. Your capacity for mental multitasking shrinks. This isn’t weakness — it’s biology.

It’s also NOT universal, so don’t go in expecting it to suck.  This will become a self-fulfilling prophecy if you let it.  Go in with a positive mindset, but know that good intentions alone may not seal the deal and you might have to dig and fight a bit.  Or a lot.

Why Brain Fog, Irritability, and Flatness Are Normal

Many competitors expect to feel tired physically, but they’re caught off guard by the mental dullness. Brain fog, emotional sensitivity, or a muted emotional range are common during prolonged deficits.

Importantly, this doesn’t mean motivation is gone. Most people still want to train, eat well, and execute the plan. It just feels harder to do so smoothly. The signal is quieter. The effort is louder.

My goal?  I like to start prep without announcing it to my wife and see how long it takes before she notices.  Invariably it’s me saying “no” to every meal out that shows my hand, my mood slips and irritability increases but only really becomes noticeable in the last few weeks typically (hmm…I wonder if SHE would agree with that!)

The Problem With Assuming Something Is “Wrong”

When these sensations aren’t expected, the default reaction is panic. People assume recovery is broken, metabolism is damaged, or that they’ve suddenly fallen behind.

That assumption is what creates problems — not the fatigue itself.

Increased Irritability and Emotional Sensitivity

You may notice a shorter fuse than usual. Minor inconveniences feel bigger. Conversations feel more draining. This isn’t a personality change — it’s reduced buffering capacity.

Calories, sleep, and accumulated fatigue all influence emotional regulation. When those inputs are strained, tolerance drops. The mistake is interpreting irritability as a reason to change the plan instead of a sign to protect energy elsewhere.

Reduced Stress Tolerance and Mental Bandwidth

Things you normally handle without thinking — schedule changes, social obligations, unexpected tasks — suddenly feel disruptive.

Prep compresses your margin for error. When everything matters, unpredictability feels threatening. That’s not a mindset flaw. It’s a constrained system doing exactly what constrained systems do.

Feeling Mentally Flat Without Losing Motivation

This is one of the most misunderstood experiences in prep. Many competitors describe feeling emotionally “flat” — not sad, not burned out, just neutral.

This often leads people to worry they’re losing their drive. In reality, it’s usually a reduction in novelty and reward signaling, not desire. Prep becomes execution-based instead of emotionally driven, and that can feel unsettling if you’re not expecting it.

Sleep Disruption, Anxiety, and Intrusive Thoughts

Later in prep, light sleep, early waking, or racing thoughts are common. Energy restriction, stress hormones, and routine rigidity all play a role.

Occasional sleep disruption isn’t automatically a red flag. The key is pattern recognition — not reacting to isolated nights.

Why Most Prep Mistakes Aren’t Physical

Most prep issues don’t start with macros or cardio. They start with discomfort that feels intolerable when mental bandwidth is low.

When fatigue is high, urgency increases. Everything feels like it needs to be fixed now. That urgency is emotional — not strategic.

Emotion-Based Changes vs Data-Based Adjustments

Emotion-based changes are driven by how you feel in the moment. Data-based adjustments are driven by trends, timelines, and objective markers.

The danger is that emotional changes often feel logical. They’re not reckless — they’re just premature.

How One Bad Day Turns Into a Bad Week

A tough day leads to unnecessary tweaks. Those tweaks increase fatigue. Increased fatigue creates more emotional reactivity. The loop feeds itself.

Very few preps fall apart because someone didn’t do enough. Many struggle because too much was changed too fast.

Obsessive Body Checking and Scale Fixation

When mental fatigue rises, reassurance-seeking increases. More mirror checks. More scale checks. Less confidence in what you saw yesterday.

This isn’t about vanity — it’s about uncertainty. The solution isn’t more checking. It’s restoring trust in the process.

Constant Urge to “Do More”

When rest starts to feel undeserved and restraint feels uncomfortable, that’s usually mental strain talking.

This is often framed as work ethic. In reality, it’s often fear wearing discipline’s clothes.

Losing Perspective on the Original Plan

If you can’t clearly articulate why your plan looks the way it does anymore, it’s time to slow down. When perspective disappears, impulsive decisions take over.

Mental fatigue during prep isn’t something you “push through” with more discipline. It’s something you manage so it doesn’t hijack decision-making. The goal here isn’t comfort — it’s stability.

Shrinking Decisions Outside of Training and Food

Decision fatigue is real, and prep accelerates it. When calories are low, every unnecessary choice drains cognitive resources you don’t have to spare.

This is why simplifying life outside the gym matters. Fewer social obligations. Predictable schedules. Less mental clutter. You’re not being antisocial or rigid — you’re conserving bandwidth so execution stays clean where it matters.

Using Routine as a Mental Safety Net

Routine becomes valuable in prep not because it’s exciting, but because it removes friction. When training times, meals, and recovery habits are predictable, your brain doesn’t have to negotiate with itself all day.

Late prep is not the time to reinvent systems. It’s the time to rely on them. Boring routines reduce decision pressure and lower the odds of impulsive changes.

When Pausing Is the Smart Move

Pausing does not mean stopping progress. It means resisting the urge to “fix” sensations that are actually temporary expressions of fatigue.

Many bad prep decisions happen because someone couldn’t sit with discomfort for a few more days. Strategic restraint is often more productive than action when mental strain is high.

Not all mental discomfort is something to simply tolerate. The skill is knowing when you’re experiencing expected prep fatigue versus something that requires adjustment.

Normal Prep Fatigue vs Legitimate Red Flags

Feeling flat, tired, or irritable is common. Feeling persistently anxious, emotionally volatile, or unable to function outside of prep is not.

If mental strain is escalating instead of stabilizing — or spilling into areas of life unrelated to prep — it deserves attention.

Communicating Early Instead of White-Knuckling

White-knuckling rarely earns extra points. Waiting until things break limits options and forces reactive solutions.

Early communication allows for small, controlled adjustments instead of emergency course corrections. This preserves both progress and confidence.

Why Addressing This Protects the Entire Prep

Unchecked mental strain eventually shows up physically — missed sessions, disrupted sleep, loss of adherence, or burnout.

Addressing mental load early protects the physical side of prep by keeping execution steady.

Mental toughness during prep is often misunderstood as emotional intensity or constant confidence. In reality, it’s the ability to stay boring and consistent when nothing feels exciting.

Consistency Beats Comfort

Prep success rarely comes from heroic effort. It comes from showing up, doing the same things well, and not changing the plan every time discomfort shows up.

Comfort is not the metric. Consistency is.

Staying Strategic Under Strain

The competitors who do best aren’t immune to fatigue — they’re just less reactive to it. They allow the process to unfold without constantly interfering.

Mental toughness isn’t about forcing motivation. It’s about protecting strategy when energy is low.
