What to Eat on 75 Hard: A Beginner's Diet Guide (No Cheat Meals, No Alcohol)
TL;DR
- 75 Hard has no official diet. You choose any eating plan you want — the rule is zero cheat meals and zero alcohol for all 75 days, no exceptions.
- The diet doesn't need to be complicated or restrictive. Simple and repeatable beats "perfect" and unsustainable — most restarts happen because someone picked a diet too extreme to hold for 75 straight days.
- Define your rules in writing on Day 1: what you're eating, what counts as a cheat, and how you'll handle restaurants, travel, and social events. Ambiguity is what causes accidental cheats.
- This guide covers how to pick a diet that survives real life, sample meal structures, eating out on 75 Hard, and how to track it without turning food into another source of stress.
The Diet Rule, Word for Word
Andy Frisella's original 75 Hard rules say this about food: "Follow a diet. Any diet. Just follow one, and no cheat meals or alcohol." That's it. There's no macro split, no calorie target, no banned food group written into the challenge itself.
That flexibility is the point — 75 Hard is a mental toughness program, not a nutrition program. But it also trips people up, because "any diet" means you have to decide the rules before Day 1, and then hold yourself to them without wiggle room for 75 days straight.
Step 1: Pick a Diet You Can Actually Hold for 75 Days
The biggest mistake beginners make is choosing the strictest possible diet because it feels like it matches the "hard" in 75 Hard. It doesn't need to. The diet just needs to be something you can follow with zero exceptions for two and a half months. A few common approaches that work well:
- Whole-food, no added sugar — eat mostly unprocessed food, cut out desserts and sugary drinks. Flexible enough for restaurants and family meals.
- Calorie deficit — track calories with any app, stay under your number every day. Works well if you already know how to estimate portions.
- High-protein — hit a daily protein target (commonly around 0.7–1g per pound of bodyweight) and otherwise eat reasonably. Simple to explain to servers and friends.
- Keto or low-carb — more restrictive, but very clear-cut rules make it easy to know instantly whether something is a cheat.
- Intermittent fasting + clean eating — an eating window plus a whole-food approach inside it.
None of these is "more legitimate" than another for 75 Hard purposes. The diet that survives is the one you can describe in one sentence and explain to a waiter without hesitation.
Step 2: Write Down Your Rules Before Day 1
Vague diets create accidental cheats. Before you start the clock, write down answers to these questions so there's no ambiguity on Day 34 at 9pm:
- What am I eating, specifically? (Name the diet.)
- What counts as a cheat meal for me? (Be concrete — "no added sugar" is stricter than "eat healthy.")
- Is alcohol-free non-alcoholic beer or wine allowed? (Most people say yes, since the rule targets alcohol itself — decide for yourself and stay consistent.)
- What's my plan for restaurants, work events, and holidays that land during the 75 days?
Having these answers written down — even just in a notes app — removes the moment of negotiation that leads to a slip. Decisions made in advance are dramatically easier to keep than decisions made in the moment, especially at a birthday party or after a bad day.
A Simple Meal Structure That Survives 75 Days
You don't need 21 unique meals. Pick 4-5 breakfasts, lunches, and dinners you genuinely enjoy and rotate them. Novelty is nice, but repetition removes decision fatigue — and decision fatigue is the actual reason most cheat meals happen, not a lack of willpower.
- Breakfast: eggs and vegetables, Greek yogurt with fruit, oatmeal with protein powder, or a protein smoothie.
- Lunch: a protein (chicken, fish, tofu, beans) with a starch (rice, potatoes) and a vegetable — batch-cooked on Sunday for the week.
- Dinner: similar structure to lunch, or a simple one-pan meal you can make in 20 minutes after a long day.
- Snacks: fruit, nuts, jerky, or protein bars that fit your chosen diet — keep a few in your bag so you're never caught hungry with only bad options nearby.
Sunday batch-cooking two or three proteins and two carb sources covers most of the week and removes the daily "what am I going to eat" decision entirely.
Eating Out Without Breaking the Challenge
You don't have to cook every meal for 75 days — that's how people burn out on 75 Hard before the diet part even becomes the problem. A few rules that make restaurants manageable:
- Check the menu online before you go and decide your order in advance — don't leave the decision to when you're hungry and looking at a dessert menu.
- Ask for dressings, sauces, and sides on the side so you control exactly what goes in.
- Grilled or baked over fried, by default, unless your specific diet doesn't care about that distinction.
- Order water or an unsweetened drink. It also helps toward your gallon-a-day requirement.
Weddings, holidays, and work travel are the days most 75 Hard attempts actually die. If you know one is coming, plan the exact meal you'll order or bring your own food. Don't leave it to improvisation.
Tracking Your Diet Without Overcomplicating It
75 Hard's diet rule is binary — you either stuck to your plan today or you didn't. You don't need a macro-tracking app unless your chosen diet specifically calls for one. Most people just need a daily checkbox: did I follow my diet today, yes or no.
That's exactly why we built the Daily Task Checklist in 75 Forge to support fully custom tasks — add "Diet" right next to your two workouts, water, and reading, and check it off once a day. The Water Tracker handles your gallon-a-day goal automatically, so you're not doing mental math on ounces at 11pm. And when you inevitably want to look back and see how consistent you really were, the Grid Tracker shows your whole 75 days at a glance — a strong deterrent against breaking a 40-day streak for a slice of cake.
75 Forge is a free download on iOS (iOS 16+), with no ads and no tracking.
What Happens If You Slip Up
If you eat something outside your chosen diet, that's a cheat meal by 75 Hard's rules — and the rule is a full restart from Day 1. There's no partial credit and no "it was just one bite." This is intentionally uncomfortable; the challenge is training your ability to keep a promise to yourself, not testing your nutrition knowledge.
If a restart happens, the diet lesson is usually the same: the plan was either too vague ("eat healthy") or too extreme to hold in real life. Tighten the definition or loosen the restriction, and go again with a plan you can actually keep for 75 straight days.
Frequently Asked Questions
Does 75 Hard require a specific diet?
No. The original rules don't name a diet — you pick any eating plan you want. The requirement is following it with zero cheat meals and zero alcohol for all 75 days.
What counts as a cheat meal on 75 Hard?
Anything that breaks the specific rules of the diet you chose for yourself on Day 1. If your diet is "no added sugar," cake is a cheat. If your diet is "no fast food," a protein bar usually isn't. Set the line before you start and don't move it mid-way.
Can I drink diet soda or coffee on 75 Hard?
Yes, as long as it fits the diet you picked. Neither is alcohol, and neither is inherently a cheat meal unless your chosen diet specifically excludes it.
What's a realistic meal plan for a busy schedule?
Pick 4-5 breakfasts, lunches, and dinners you like and rotate them. Batch-cook proteins and carbs on Sunday. Repetition beats novelty when the goal is 75 days without a single mistake.
How do I track my diet alongside the rest of 75 Hard?
Most people just need a daily yes/no checkbox rather than a full food-logging app. 75 Forge's Daily Task Checklist lets you add a custom "Diet" task next to your workouts, water, and reading, so everything lives in one place.
The Bottom Line
75 Hard's diet rule is deceptively simple: pick anything, follow it perfectly. The people who finish aren't the ones who chose the most extreme plan — they're the ones who chose a boring, repeatable plan and defined their rules clearly enough that there was never a gray area to argue with themselves about at 9pm on a hard day.
