06 Oct Eating well all week but not losing weight? Your weekend might be why
October 6th, 2026
“The weekend isn’t ruining your progress. But it might be hiding it”.
‘Weekenditis’. I’m not sure where I first heard this phrase but these days I use and discuss it regularly with my clients. Let’s see if you recognise the symptoms:
From Monday to Friday, you’re in control. Breakfast has some protein in it. Lunch is sensible. You’ve walked, trained, or at least thought about it. By Thursday evening you’re feeling pretty good about having had a week which aligns with your goals.
Then Friday evening arrives…
A takeaway to mark the end of the week. Wine, or maybe a couple of pints (because you’ve earned it). A restaurant on Saturday, the kid’s leftovers picked off their plates, a slightly bigger breakfast ‘because it’s the weekend’, and a maybe a family dinner with all the trimmings. Come Monday morning, the scales haven’t moved. Perhaps they’ve crept up. And you wonder: why am I not losing weight?
None of this is a problem in itself
Just to be crystal clear: I’m not here to tell you to give up any of the above. A Sunday roast with your family is one of life’s great pleasures. Nobody ever lay on their deathbed wishing they’d said no to a Friday curry.
The issue isn’t any single meal. It’s what happens when they all land in the same 48 hours.
Weekly energy balance – explained:
Your body doesn’t reset at midnight on Sunday. It looks at your intake and your output across the whole week, and what matters is where the total lands.
Here’s an illustration (the numbers are examples, not prescriptions). Say you eat 400 calories below maintenance on each of five weekdays. That’s a 2,000 calorie deficit… a solid week’s work. Now say Friday night’s takeaway, a couple of glasses of wine, some dessert, and a few unplanned nibbles push you 1,000 calories above maintenance on both Saturday and Sunday. That’s 2,000 calories back.
Net result: zero. Five good days, cancelled out by two.
This is surprisingly easy to do, too. A restaurant meal with a starter, a main, a drink or two and a shared pudding can comfortably reach 2,000 calories or more on its own. And in that moment (unlike Christmas day at 4pm), you won’t feel like you overate.
The wrong solution: banning the weekend
The instinct is to clamp down. No more takeaways, no wine, no roasts. Strict, seven days a week.
This strategy is doomed from the start. Social occasions are one of the joys of life, and a plan that has no room for them is a plan you’ll abandon within three weeks. This normally comes with a ‘f**k it’ moment, where one slip escalates into a whole weekend written off, with the ‘damage’ being much worse than it could have been.
The better solution: choose what matters
Instead of asking “what must I give up?”, ask: which of these indulgences do I actually want?
The Sunday roast with your family? Absolutely worth it. The cold fish fingers you finished off the kids’ plates without noticing? Not so much. The second helping of rice at the takeaway when you were already full? Probably not. Keep the things you’d miss. Drop the ones you wouldn’t remember.
Plan around the big meal
If you know you’ve got a biggie over the weekend, work with it:
- Make breakfast and lunch work for you. A protein-rich breakfast and a lighter lunch with plenty of veg and lean protein leaves room for dinner without arriving ravenous.
- Don’t skip meals to ‘save up’. It usually ends with overordering and eating too quickly.
- Add some movement. A long walk with friends or family, or a trip to the park will help, and it’s better company than the treadmill.
Be honest about the alcohol
Alcohol is the stealth contributor. Calories in drinks don’t fill you up, and a few glasses across the weekend can add up to a whole extra meal. It also lowers your inhibitions around food (hello, 11pm toast/kebab/fridge raid), and it tends to wreck your sleep, which makes you hungrier the next day.
There is no need to go teetotal. Decide in advance how many you’ll have, pick drinks you genuinely enjoy, and alternate with water. Awareness is more than half the battle.
Don’t turn Monday into punishment
If the weekend went big, resist the urge to starve yourself on Monday or add an hour of ‘penance cardio’. This is the exact cycle that keeps people stuck. Simply make your next meal a good one. Then the one after that.
The takeaway (pun intended haha)
You don’t need seven perfect days. You need seven days that belong to the same plan. I’ll help you put that together.

P.S. I’m not normally a numbers guy, but if you are, I once put together a handy tool to help you build awareness. Click here to check out my calorie calculator.
P.P.S. “Why does a coach who doesn’t think that you should count calories promote a calorie counter?”
Most coaches use these things as a stepping stone to MyFitnessPal and a lifetime of tracking calories, and that’s the only way they coach. But there’s another way to think about calorie counters, and that’s education, awareness, and understanding your baseline.
By understanding where your calories are at right now, we can look at the food you’re consuming and see how far above or below you are for your goal. This can really help inform the positive changes that need to be made right away, before quickly moving you into more habit-based (and longer-lasting) approaches.
