10 Benefits Of A Plant-Based Diet: Why Your Body Will Thank You


Published on August 4, 2025 by Susie Mccoy

So there I was, standing in Tesco at half past nine on a Tuesday night, staring at a packet of processed chicken nuggets and wondering how my life had gotten to this point. My wife had taken the kids to her mum’s for the week, and I’d been living on absolute garbage. Pot Noodles for breakfast, meal deals for lunch, whatever I could shove in the microwave for dinner.

Then my neighbour Karen, yeah, that Karen, knocked on my door with a casserole dish. “It’s lentil and vegetable,” she said, looking at me like I was some sort of charity case. Which, honestly, I probably was. That casserole changed everything. Not because it was life-changing or anything dramatic, but because I actually felt decent after eating it. No bloating, no food coma, just… normal.

That was eighteen months ago. Here’s what happened when I accidentally stumbled into eating more plants.

Blood Pressure Went From Mental to Normal

My GP had been nagging me about my blood pressure for years. “You’re heading for trouble,” she kept saying. I’d nod and promise to eat better, then grab a bacon sandwich on the way home.

Three months after eating mostly plants, my reading dropped from 165/95 to 125/80. Dr Martinez nearly fell off her chair. “Whatever you’re doing, keep doing it,” she said. Turns out all that fibre and potassium in vegetables actually works. Who knew?

Weight Loss Without Being Miserable

I wasn’t even trying to lose weight. Seriously. I was just eating different food, loads of it too. Massive bowls of pasta with tomato sauce, enormous salads, proper hearty stews with beans and vegetables.

Lost two stone without counting a single calorie. My old jeans fit again. My back stopped aching. Even managed to see my feet without bending over, which was a bonus I hadn’t expected.

Cholesterol Numbers Made Sense Again

The pharmacy machine used to flash red whenever I checked my cholesterol. Proper embarrassing when there’s a queue behind you. Now it shows green numbers that don’t require a second mortgage for statins.

My brother reckons it’s genetics; “Dad had high cholesterol too.” Yeah, Dad also lived on sausage rolls and never met a vegetable he liked. Maybe that’s connected?

Digestion Stopped Being a Daily Battle

Right, let’s talk about the toilet situation. Before plants, I was either constipated or rushing to the loo at inappropriate moments. No middle ground whatsoever.

Now everything works like clockwork. No more carrying Imodium in my wallet or planning routes around public toilets. Fibre from beans and vegetables sorted me right out, though there was a windy adjustment period that my family still reminds me about.

Energy Levels Became Actually Useful

Used to crash every afternoon around three. Proper zombie mode. Coffee helped for about twenty minutes, then I’d feel worse than before.

These days I’m still going strong at teatime. Last week I painted the spare bedroom after work. My wife thought I’d had some sort of breakdown, but I just felt like doing something instead of melting into the sofa.

Sleep Improved Without Trying

Never connected food to sleep before, but apparently eating lighter meals helps you rest better. Who would have thought that demolishing a massive steak pie before bed might cause problems?

Now I sleep through the night most of the time. No more 2am acid reflux or weird dreams about being chased by giant hamburgers. Just normal, boring sleep that leaves me feeling human in the morning.

Cancer Risk Dropped (Hopefully)

This one’s harder to measure day-to-day, but the research is pretty clear. Plants contain stuff that fights cancer cells. My uncle died of bowel cancer at 58, so this matters to me.

Can’t prove that eating more vegetables will save my life, but it certainly won’t hurt. Better than doing nothing and hoping for the best, which was my previous strategy.

Joint Pain Basically Disappeared

My knees used to ache after playing football. Hobbling around like an old man at 45 wasn’t a good look. The inflammation from processed food was making everything worse, apparently.

Last month, I played two games in one weekend and felt fine afterwards. The lads think I’m on some sort of performance enhancer. If only they knew it was chickpeas and spinach.

Diabetes Risk Got Manageable

My dad’s diabetic, my uncle’s diabetic, half my family’s on medication for blood sugar problems. The writing was on the wall for me too, according to my last blood test.

Plant foods keep your blood sugar steady instead of sending it on a rollercoaster ride. No more afternoon sugar crashes that had me raiding the biscuit tin. My HbA1c results actually impressed the nurse.

Mental Clarity Improved Somehow

This sounds like complete nonsense, but my head feels clearer these days. Less foggy, more able to concentrate on things. Maybe it’s better sleep, maybe it’s stable blood sugar, or maybe it’s just feeling physically better overall.

Whatever it is, I’m not complaining. Actually finished reading a book last month instead of falling asleep on page three.

My Take

The thing about these 10 benefits of a plant-based diet is they creep up on you. I didn’t wake up one morning feeling amazing. It was gradual changes over weeks and months. Better skin here, more energy there, clothes fitting differently.

My mate Steve reckons I’ve joined some sort of cult. “You’re always banging on about vegetables now,” he says. Fair point, I probably am. But when something works this well, it’s hard not to get excited about it.

I’m not saying everyone needs to become a full-on vegan overnight. That’s mental. Start small; maybe try having beans instead of meat once a week, or sneak some extra vegetables into your usual meals. See what happens.

The 10 benefits of a plant-based diet aren’t just theory; they’re real changes that happen to real people. Including stubborn middle-aged blokes like me who thought vegetables were just something that came on the side of a proper meal.

Best decision I never meant to make, honestly. Even Karen’s stopped bringing me casseroles now that I can feed myself properly. Though I do miss that lentil one, might have to ask for the recipe.
