Setting health goals is easy. Sticking to them is the real challenge. The secret is choosing goals that are clear, achievable and flexible enough to survive the ups and downs of daily life. Below are five research-supported strategies you can put into practice straight away – each with a simple weekly action to help you stay motivated.

1) Make your goals SMART but kind to yourself

SMART goals (Specific, Measurable, Achievable, Relevant and Time-bound) transform vague intentions into clear steps you can act on.

Instead of saying, “I want to eat healthier,” try something like: “I’ll include two portions of vegetables at dinner, at least five nights a week for the next month.”

SMART goals create clarity and remove the guesswork, which makes you far more likely to stick with them.

Try this week: Rewrite one of your goals using the SMART structure. Think of it as an experiment, not a commitment set in stone.

2) Use implementation intentions to turn intentions into action

Intentions often fall apart at the crucial moment of choice. That’s where implementation intentions – simple if–then plans – come in. For example: “If it’s 7am, then I’ll go for a 10-minute walk.”

These plans link a specific situation with a specific behaviour, making follow-through much easier. Decades of research from psychologist Peter Gollwitzer shows that if–then plans dramatically improve the chances of success.

Try this week: Choose one SMART goal and create an if–then plan for it. Put it somewhere you’ll see it daily.

3) Start tiny and stack habits so momentum works in your favour

Small wins build confidence, and confidence builds consistency. Behaviour scientist BJ Fogg recommends starting with “tiny habits” (like one squat or one extra sip of water) and attaching them to something you already do every day. This is known as habit stacking.

For example: “After I make my morning tea, I’ll add a piece of fruit to my breakfast.”

This reduces friction and anchors your new behaviour to an existing routine. You can explore this approach in BJ Fogg’s Tiny Habits method on the Tiny Habits website or in James Clear’s simple guide to habit stacking.

Try this week: Pick a micro-habit that supports your goal and attach it to a daily routine you never miss.

4) Track your progress – not to judge yourself, but to learn

Tracking increases awareness, and awareness drives better choices. Studies show that people who keep a simple food or behaviour diary tend to make more positive changes over time. It doesn’t need to be detailed or perfect. Even brief notes can reveal helpful patterns.

Try this week: Track your food, activity or mood for seven days. Review it at the end of the week and choose one insight to apply.

5) Focus on motivation that lasts: autonomy, competence and connection

Long-term motivation isn’t just about willpower. According to Self-Determination Theory (SDT), people stick with healthy behaviours when they feel:

Autonomy: the goal is genuinely theirs
Competence: they feel capable of succeeding
Relatedness: they feel supported by others

When your goals are personally meaningful and socially supported, they’re far more sustainable. You can explore the research behind SDT at the Self-Determination Theory website.

Try this week: Write down why your main health goal matters to you. Then tell a friend or coach so you have gentle accountability.

A simple structure to combine all five strategies

SMART goal: “Walk for 20 minutes after lunch, Monday to Friday, for four weeks.”
Implementation intention: “If I finish lunch, then I’ll put on my shoes and walk for 20 minutes.”
Start tiny: If 20 minutes feels too much, begin with 10.
Track: Tick off each day on a calendar or app.
Motivation check: Revisit your “why” and share progress with someone supportive.
