Gen Z Is Done with “Dieting”—Now It’s Total Reset

If you thought health resolutions meant joining a gym and eating a few more greens, young Brits are now treating January like a full system reboot. A new poll suggests the modern New Year mindset is less “small improvements” and more “hard reset”: daily ice therapy, zero caffeine, social media blackouts, and a growing taste for clean-living rules that leave very little room for a normal Tuesday.

The survey, commissioned by premium food delivery service Frive, paints a familiar picture with a sharper edge: younger adults are bored of the old routines and suspicious of quick-fix fads from the past. It’s not that people don’t want to feel better. It’s that “join a gym” no longer feels like enough of an answer to stress, screens, work pressure and the general hum of modern life.

From “resolution” to “reset”

Plenty of traditional health resolutions still show up—meditation, moving more, eating better—but they’re now packaged as firm rules rather than gentle intentions. In the poll, pledges ranged from cutting out caffeine to swearing off dating apps and committing to celibacy for the year. Food rules were especially common, with respondents talking about cutting out sugar entirely, going wheat- and dairy-free, and avoiding ultra-processed foods.

Then there’s the more dramatic end of the list: daily cold exposure and vitamin IV drips—wellness choices that look bold on Instagram, but can slide quickly into performative self-discipline if the basics (sleep, meals, movement) aren’t in place.

What you’re seeing, in plain terms, is a shift in health resolutions from “do a bit more” to “control everything”.

The real problem: time, not willpower

Here’s the part that matters for readers: even among people making big promises, many already suspect they won’t keep them. The poll indicates a sizeable chunk of adults think they’ll fail their diet goals, and most wish there were a simpler way to stay on track.

That’s the story behind the extremes. People aren’t short of motivation; they’re short of time and headspace. When life is busy, grand plans collapse first—especially the ones built on bans, perfection and all-or-nothing rules.

Which is why the best section of this release is the part that quietly brings everyone back to earth.

“modern life is busy, which is why sustainable habits matter…”

Nutritionist Sophie Trotman, who is working with Frive, offers the antidote to the January “punishment” mindset:

“Modern life is busy, which is why sustainable habits matter. Focusing on simple things like balanced meals, immune-supportive foods and not taking an all-or-nothing approach to sugar can help people stay energised and committed long beyond January.”

It’s a line worth leaning on because it respects ambition without encouraging self-sabotage. Most health resolutions fail for the same reason: they’re designed for an imaginary version of your week.

Sophie Trotman’s top tips

1. Support your body, don’t punish it
After December’s late nights, richer food and extra drinks, your body doesn’t need extremes – it needs support. Focus on fibre-rich vegetables like broccoli, kale and Brussels sprouts, alongside plenty of water to help digestion and energy levels rebalance naturally.

Adding colourful, antioxidant-rich foods such as berries, citrus fruits and leafy greens can help you feel more energised and less sluggish, without turning January into a harsh detox.

2. Prioritise protein to stay fuller for longer
One of the biggest reasons people quit healthy eating is constant hunger. Protein helps stabilise blood sugar, supports muscle recovery after workouts and keeps you feeling full for longer – reducing the temptation to snack.

Aim to include a protein source like eggs, fish, chicken, tofu or lentils at every meal. When time is tight, a balanced Frive meal makes it easier to stay consistent without the prep.

3. Eat to support immunity and resilience
With stress levels high and routines disrupted, January can take its toll. Foods rich in vitamin C (such as citrus fruits and peppers), zinc (nuts, seeds and seafood) and protein can help support your immune system and overall resilience.

A balanced diet won’t prevent illness entirely, but it can help your body cope better with the demands of modern life.

4. Be intentional with sugar, not all-or-nothing
Many people vow to quit sugar entirely, but that approach can backfire. Instead of cutting everything out, enjoy sweet foods mindfully. Slow down, sit down, and actually taste what you’re eating rather than grazing absent-mindedly.

Pairing sugary foods with protein or healthy fats – like yoghurt or nuts – can help prevent energy crashes and make healthier habits easier to stick to long term.

5. Keep meal timing realistic
Late-night eating can disrupt sleep and digestion, especially during busy weeks. Where possible, aim to eat your evening meal two to three hours before bed to give your body time to wind down properly.

Simple shifts like this support steadier energy, better sleep and more balanced appetite the next day – helping you stay on track long after Quitter’s Day.

The bottom line on 2026 health resolutions

The modern appetite for “extreme” health resolutions isn’t random—it’s a response to a culture that feels permanently switched on. Some of these pledges are harmless, even helpful. Others are brittle, and brittle plans don’t survive real life.

The smartest approach isn’t to out-suffer January. It’s to build a routine you can repeat in February—without needing to declare war on caffeine, sugar, your phone, and your social life all at once.
