Fast Food Survival Guide

Fast food gets treated like the enemy of fitness.

It's not.

What ruins diets isn't McDonald's or KFC. It's the all-or-nothing thinking that makes people believe one "bad" meal is a disaster — so they might as well go all-in and order three courses, a large meal, and dessert

Fast food is food. Calories in, calories out still applies. The problem is most people have no idea what they're actually eating when they order fast food, so they either avoid it entirely (until they cave and go mental on it) or they order everything without thinking and wonder why they're not losing weight

This guide gives you the exact orders I've recommended to clients for years. High protein, reasonable calories, and actually available at the places you're already going to.

For context on how fast food fits into a broader strategy, see how to eat out and stay on track. And for high-protein snack options when you're away from restaurants, check high-protein snacks in the UK.

The Fast Food Mindset Shift

Before I get into specific orders, you need to understand one thing: every fast food restaurant has good options and terrible options.

The difference between a solid meal and a diet-wrecking meal at McDonald's often comes down to 2 or 3 choices. Same restaurant. Completely different outcome.

Your job is to:

1. Get a solid protein source in the meal
2. Limit the extras (sauces, sides, drinks) where the hidden calories live
3. Not treat it as a "cheat" that justifies going off the rails for the rest of the day

That's it. Let's get into the orders.

McDonald's

McDonald's is everywhere. It's cheap. And there are genuinely decent options if you know what to pick.

Best orders:

• Grilled Chicken Wrap — decent protein, not too heavy on calories, skip the mayo if you're cutting hard
• McChicken sandwich — reasonable protein hit, skip the large fries
• Double Hamburger — surprisingly decent protein-to-calorie ratio compared to the Big Mac
• Egg McMuffin (breakfast) — one of the best options on the whole menu, high protein, low calorie

What to avoid:

• Large meals and large drinks — the jump from medium to large adds hundreds of calories for no real satisfaction benefit
• McFlurries and desserts added on — this is where people quietly add 400 extra calories to their order
• Extra sauces — a few sachets of sauce can add 150-200 calories without you noticing

The move: Grilled chicken option, medium or skip the fries entirely, water or diet drink. You're out under 500 calories with a solid protein hit.

KFC

KFC is actually one of the better fast food spots for protein if you order correctly.

Best orders:

• Original Recipe chicken pieces — original beats extra crispy for calories, and the chicken itself is decent protein
• Zinger burger — higher protein, just skip the chips or swap for corn on the cob
• Rice Box with chicken — one of the better value-for-nutrition meals on the menu

What to avoid:

• Popcorn chicken as a main — mostly batter, not much actual chicken
• Adding gravy and extra sides — the sides at KFC are where the calorie damage gets done
• The large bucket sharing meals when you're alone — obvious but worth saying

The move: Two or three pieces of original recipe chicken, corn on the cob instead of fries, water. Affordable, filling, high protein.

Subway

Subway is probably the most diet-friendly of the major fast food chains, and most people still manage to over-order here.

Best orders:

• 6-inch sub with chicken breast or turkey — one of the highest protein-to-calorie options in fast food full stop
• Protein bowl (no bread) — if you're really watching calories, the bowl version cuts out 200+ calories without sacrificing anything that matters
• Tuna 6-inch — higher in fat but good protein, solid option if that's what you want

Bread choice matters: White Italian bread and hearty Italian are the lightest options. Avoid the flatbread — it sounds healthier but has more calories than the regular bread.

Sauce matters a lot here: Subway is where people destroy their otherwise reasonable meal. A few pumps of chipotle southwest or Caesar sauce adds 200-300 calories. Go for mustard, vinegar, or a small amount of light mayo.

Load the vegetables: Salad, spinach, cucumber, peppers, onions — pile these in. Zero meaningful calorie impact, massive volume.

The move: 6-inch chicken breast on hearty Italian, load the vegetables, mustard or a small amount of sauce, no cookies, water or diet drink. You're walking out with a high-protein meal under 400 calories.

Nando's

Nando's is one of the best fast food spots for anyone trying to eat well. Grilled chicken as the core, loads of options, actually customisable.

Best orders:

• 1/4 chicken breast — lean, high protein, exactly what you want
• Whole chicken if you're sharing — efficient protein source
• Chicken pitta or wrap — good option, reasonable calories

Smart sides:

• Corn on the cob — low calories, filling
• Coleslaw (in moderation) — decent but watch the portion
• Side salad — always a good addition

Skip or limit:

• Peri-peri chips as the only side — fine occasionally, just don't make it every visit
• Adding halloumi and extra starters — the sides stack up fast

The move: Quarter chicken breast, medium spice, corn on the cob, side salad. One of the cleanest fast food meals available. High protein, relatively low calorie, properly filling.

Greggs (and similar bakery chains)

I know. But people eat here regularly, so let's talk about it.

Best options:

• Sausage, bean and cheese melt — higher protein than most pastries, but still calorie-dense
• Chicken bake — one of the better protein options in the range
• Breakfast roll with egg — add egg, skip extra sauces

The honest truth about Greggs: Most of their range is pastry-based, which means high fat, high carb, modest protein. It's not ideal for dieting but if it's your only option:

• Pick items with a protein filling over pure pastry items
• Have one item, not a bag
• Pair with a black coffee or water, not a sugary drink

Deliveroo / Just Eat Orders

The real danger zone. It's 10pm, you're tired, the app is there, and the minimum order is £15 so you have to add more things. The best defence against this scenario is having prepped food ready — the meal prep guide for busy men shows you how to batch-cook 5 days of food in 2 hours on Sunday.

Rules for delivery orders:

1. Decide your order before you open the app. Open hungry and you'll order twice what you need.
2. Pick a protein-forward main: grilled chicken, kebab meat, tandoori dishes, grilled fish.
3. Skip the extras: naan, extra rice, garlic sauce, drinks — these are where the damage happens.
4. If there's a minimum order, add a drink or a simple side — not an extra burger.

The kebab shop and grill restaurants that dominate most delivery apps are actually decent options: mixed grills, shish kebabs, chicken pieces. High protein, relatively lean if you skip the bread and sauce overload.

The Rule That Ties It Together

Here's what I tell every client when they ask about fast food:

You can eat fast food and still lose fat. You cannot eat fast food mindlessly and expect results.

If social occasions involve alcohol alongside the fast food, the alcohol and dieting survival guide covers how to handle both without blowing your week. And between meals, keep high-protein snacks on hand — they're the backup that stops you making desperate choices when hunger hits.

The difference is awareness. Know roughly what you're ordering calorie-wise, prioritise protein, skip the extras that add hundreds of calories with no satisfaction, and move on.

One fast food meal doesn't erase your week. What erases your week is deciding the meal "ruined" your day and eating badly for the next 4 days on top of it.

Make the best choice available with what you've got. That's what consistent fat loss actually looks like. For sit-down restaurant strategies and handling social pressure around food, check out the eating out while dieting guide. And if you're not sure what your daily protein target should be, sort that out first — it makes every food decision easier.
