Switching to a vegan diet can be a wonderful, health-oriented, ethical decision — if done thoughtfully. But in practice, many people jump in too fast, under social pressure, without planning, and then struggle. Here’s a look at what often happens behind the scenes, backed by studies and real-life observations — and how to avoid the pitfalls.
1. The social trigger: “Everyone’s doing it”
It’s not unusual to feel nudged into change by colleagues, documentaries, or trending social media posts. When you see someone at work switching to veganism, or hear about a compelling exposé, the pressure to “join the club” can be strong.
Social influence on food choices is real. A campus study of 38 million food purchases found that when people begin regularly eating with someone whose diet is “healthier,” their own choices shift significantly in that direction.
The risk? You adopt the label of “vegan” before your habits, body, or mindset are ready — and without a step-by-step plan.
2. Lack of structure and baseline habits
Many people who embark on the vegan journey haven’t had a solid pattern of meal planning or disciplined diet habits beforehand. Without structure, the initial enthusiasm often leads to shaky foundations.
One common pattern:
- Start with lots of salads, green juices, and “clean” plant foods.
- But life gets busy: work deadlines, errands, late nights.
- You find yourself scrambling for convenience food or packaged snacks with refined sugar.
- Because vegan options at convenience shops often include sugary or ultra-processed items, you slip into less ideal choices.
Over time you may feel fatigued, low in energy, or even run down. And if you get a cold or flu, it’s easy to blame external causes — but it can be a signal your body isn’t getting steady fuel or key nutrients.
3. Label anxiety & food scarcity mindset
Once you fully commit to “vegan,” you may start scrutinising every label in panic: “Does this have hidden dairy? Eggs? Gelatin?” That mindset — “there’s nothing I can eat” — becomes a mental burden.
Because many people transition without understanding how to build balanced vegan meals (i.e. combining protein, healthy fats, fiber, micronutrients), the diet can become carb-heavy and imbalanced. This leads to:
- Mood swings
- Cravings
- Possible weight gain
- Low motivation
Indeed, some studies suggest vegetarian or vegan diets are associated with higher rates of depressive symptoms compared to omnivores — though causation is unclear and evidence is mixed.
A 2021 BMJ-NPH study found that “high-quality” plant-based diets (rich in whole foods, not processed) are linked to lower depressive symptoms, whereas low-quality plant diets (lots of processed foods) correlate with worse mood.
4. The slippery slope of hybrid labels: “Pesto vegetarian,” “dairy pesto,” etc.
To cope, many become “flexible” in their definitions:
- Add in cheese → “dairy pesto vegetarian”
- Add eggs → “pesto dairy egg vegetarian”
- Use processed vegan meat substitutes
This evolution often happens unconsciously. Because there’s no solid launch plan, your diet becomes a patchwork, and your identity shifts incrementally to reduce discomfort.
In many cases, this “sliding scale” reflects not nutritional logic, but social adaptation and psychological ease.
5. Why it backfires: body, brain, and lifestyle resistance
Changing your diet radically is a major shift — and your body, brain, gut microbiome, and daily habits need time to adapt. Without giving them that time, friction arises.
- You may feel low energy, brain fog, or mood changes.
- You might catch colds more easily, especially if your immune system is weakened by nutrient gaps.
- You may start second-guessing every food (label paralysis).
- You might gradually “relapse” into hybrid forms because pure veganism feels too strenuous or isolating.
In qualitative interviews, vegan adherents often report “temptation to return,” “constant criticism,” and “emotional turbulence” during the transition period.
Barriers like “extreme hunger,” “stress,” and “anxiety” are commonly reported in the early months of switching diets.
6. What studies
do
say about veganism (and why planning matters)
To be clear: well-planned vegan diets can offer health benefits (lower cholesterol, reduced risk of some chronic diseases) — but they require intentional design.
For example, a twin study (identical twins, one vegan, one omnivore) showed that after 8 weeks the vegan twin had lower LDL cholesterol, reduced insulin, and modest weight loss.
But even that study acknowledged that adherence, nutrient balance, and diet quality matter hugely.
Another review warns: simply being vegan doesn’t guarantee health — if your diet is full of refined grains, sugary drinks, and processed vegan junk, your risk of cardiovascular disease or mortality can increase.
7. A healthier approach: step by step, with support
If you genuinely want to try veganism (or plant-based living), here’s a roadmap to reduce friction, frustration, and feeling like you’ve been swept up by a trend.
Step 1: Clarify your “why.”
Is it health? Ethics? Sustainability? Social belonging? Understanding your motivation will anchor you when things get hard.
Step 2: Build baseline habits before switching.
Practice regular mealtimes, balance, protein or legumes, veggies, fats, snacks. Build discipline before removing animal foods.
Step 3: Educate yourself about essential nutrients.
Protein, B12, iron, zinc, omega-3s, vitamin D — ensure you know reliable plant sources or supplements.
Step 4: Transition gradually.
Start with meatless days, or shift one meal at a time. Use familiar recipes. Give your gut time to adjust.
Step 5: Prioritize whole foods, not just “vegan-labeled” products.
Minimize processed substitutes, refined carbs and sugary vegan snacks.
Step 6: Monitor, reflect, iterate.
Track energy, mood, weight, digestion. Be honest. If something isn’t working, tweak — don’t give up entirely.
Step 7: Build a supportive environment.
Find friends, mentors, nutrition professionals, or a community. Avoid feeling isolated or pressured by trends.
Final word
Going vegan because a colleague did is tempting — it offers a visible target, social validation, and a feeling of belonging. But without careful planning, you risk frustration, nutrient imbalances, and emotional strain.
A better path is one you design intentionally: with awareness, structure, gradual steps, and self-compassion. That way, your diet becomes your choice — not a fad you regret.
