Should I Change My Diet? A Values-Based Decision Framework
You know your diet should change, but the landscape of nutritional advice is contradictory and overwhelming. Every approach claims to be the answer—keto, vegan, paleo, intuitive eating. You're trying to figure out what actually works and whether you can stick with it.
Key Takeaway
This decision is fundamentally about Physical Health vs. Sustainability. Your choice will also impact your relationship with food.
The Core Values at Stake
This decision touches on several fundamental values that may be in tension with each other:
Physical Health
Your desire to improve health markers and feel better. Consider what specific health goals you're trying to achieve.
Sustainability
Your ability to maintain changes long-term. The best diet is one you can actually stick with.
Relationship with Food
Your psychological and emotional connection to eating. Consider whether restrictive diets help or harm this relationship.
Energy and Performance
How food affects your daily functioning. Evaluate whether proposed changes would enhance or impair your energy.
Social and Cultural Factors
How diet changes would affect your social life and cultural practices. Extreme diets can isolate you.
5 Key Questions to Ask Yourself
Before making this decision, work through these questions honestly:
- 1What specifically do I want to change, and why?
- 2What has prevented previous diet changes from sticking?
- 3Am I drawn to this diet because of evidence or because of marketing?
- 4Can I realistically maintain this way of eating long-term?
- 5Is my relationship with food healthy, or could extreme dieting make it worse?
Key Considerations
As you weigh this decision, keep these important factors in mind:
Watch Out For: Diet Tribalism
Diet communities create intense in-group identity—keto devotees, vegans, carnivores all claim to have the answer. But nutrition science shows that many different approaches can work. The best diet is the healthy one you'll actually follow. Be wary of any approach that claims to be universally superior.

You know you should exercise more, but starting feels overwhelming. Which program? How often? Will you even stick with it? Past failed attempts have left you skeptical. You're trying to find an approach you'll actually maintain rather than abandon after two weeks.
Should I Join a Gym?
You know you should exercise more, and a gym seems like the answer. But past memberships have gone unused, and you're not sure if you'll actually go or just waste money on good intentions. You're trying to decide if this time will be different.
Should I Start Therapy?
You've been thinking about therapy but can't decide if you really need it. Maybe things aren't bad enough. Maybe you should be able to handle this yourself. The stigma, cost, and vulnerability of opening up to a stranger all create resistance, even as you sense it might help.
