1. You know what to do, but you don’t do it.
You're smart, capable, and have read every nutrition tip under the sun but when life gets chaotic, you fall back into old habits.

2. You’re all-in or all-out.
One slip-up and it's a free-for-all. You can nail it for a week, then undo it all in a weekend. Consistency becomes boring.

3. You’re white-knuckling discipline without structure.
You rely on willpower, not systems and it works for a while… until you get tired, stressed, or busy. Then it all unravels.

4. You’ve made food emotional.
Stress, boredom, loneliness your meals are doing more than fuelling you. They're coping mechanisms, not just choices.

5. You think setbacks mean failure.
Any time you slip, you take it personally. Instead of learning from it, you spiral. You don’t need motivation you need a mindset shift.

At ByDesign, we focus on tackling your concerns from the inside out. This isn’t about strict meal plans or “one-size-fits-all” routines. You’ll get real-life, evidence based tools to help you understand what your body needs and the structured support to actually implement it.
