I have been on both sides. That is why my approach is different.
I am Ruwi, an AfN registered nutritionist, based in London and coaching entirely online. I work with women who are tired of dieting and restarting, and who want food to stop feeling like the enemy.
My story.
Growing up, I was uncomfortable in my own body. I hid in baggy clothes, dreaded summer, and compared myself to other girls, convinced my body was something I needed to fix.
At 14, I decided to lose weight. Without the right guidance, I did what the world tells you to do: eat less, cut things out, control everything. I developed anorexia, and it took me years to find my way out.
Recovery taught me something no textbook could. Restriction does not build anything lasting. It just postpones the problem. And the moment the rules are gone, the old patterns come straight back, because nothing underneath has changed.
"A diet tells you what to do for 30 days. It does not change who you are."

What I learned from recovery, and from working with women.
You might know what you want to eat and still find lunch gets pushed aside when work piles up. Knowing what would help and finding a way to do it in your own week can take some working out.
In our sessions, we look at where things get difficult. If lunch keeps getting missed, we can talk through what you could bring from home or buy near work, and when you could make time to eat it.
We agree on a change to try, then come back to it at your next check-in. Tell me what was awkward. That helps us work out what to adjust.
- Three balanced meals land in her day without much thought, and the protein takes care of itself with no gram-counting.
- A craving for something sweet stays a craving, handled in the moment instead of turning into a spiral.
- Wine, pasta and chocolate are all on the menu, because she understands how they fit.
- Friday dinner out happens, and Saturday is not spent compensating for it.
- One imperfect evening stays an evening, and Monday is just Monday.
- Movement happens most days because it has become part of how she lives, with no punishment attached.
That is what leaving the all-or-nothing mindset looks like day to day.
How I measure progress.
The women who work with me experience the weight loss journey differently. Because alongside nutrition, I teach them to track progress beyond the scale: how they move, how their energy feels, how they are improving at the gym, how naturally healthy habits are becoming part of their everyday life.
I also work on mindset. Understanding that weight fluctuations are normal, that progress is not linear, and that one imperfect week does not undo everything. When that clicks, the whole journey changes.
What working together looks like.
Bring the food questions that come up in your week. Perhaps you have a dinner out coming up and feel unsure what to order. We can talk through the options and how they fit with what you are working on.
Between sessions, you can message me if something we discussed turns out to be difficult to put into practice. We can look at what happened and discuss an adjustment before your next check-in.
I know the science, and I know what this feels like from the inside. For a lot of women, that combination is what has been missing.
"That is not a failure. That is a Tuesday."
