Most women are shocked at how much they can eat and still lose weight. Let’s find your number.

No starving, no joyless tiny portions, no earning your food. Just the honest number you can lose fat on, built on protein and real food that actually fills you up.

Key takeaways

The short version.

Five key points to remember

  • 01Most women can lose fat on more food than they expect, often well above the very low numbers they’ve been told to stick to.
  • 02A moderate deficit beats a brutal one. It’s livable, it protects your muscle, and it’s the one you can actually stick to.
  • 03Protein is the lever that matters most. It keeps you full and holds onto the muscle that reshapes you while you lose.
  • 04You won’t count forever. The number is a starting point, not a life sentence.
  • 05Whole food is hard to overeat. Ultra-processed food is made to be easy to overeat. That is the whole game.
“I thought eating so little was the price of staying slim. It turned out to be the reason the weight always came back.”

A note I hear often, in one form or another

Why the number feels high

You’ve been told the opposite your whole life, so this might feel wrong at first. For most women who land on a page like this, the reason the scale won’t move was never willpower, and it was never about wanting it badly enough. It comes down to the food itself, which never really kept you full.

You’ve probably been good for weeks with nothing to show for it. Skipped breakfast to “save” calories, then found yourself starving by the afternoon and snacking all evening. And underneath it sits one quiet fear: if I eat more, I’ll undo everything.

Here’s what’s actually happening. When most of what you eat is processed and easy to overeat, it goes down without ever filling you, so you end up eating more than you meant to, and more than you’d ever guess. That isn’t a discipline problem. That food is built to be easy to keep eating. Swap it for whole food that genuinely satisfies you, and the very same appetite leaves you eating less, without the fight.

This isn’t the old “starvation mode” scare. The answer was never to push your food lower and white-knuckle your way through. It’s to change what’s on the plate, so a gentle deficit stops feeling like punishment and starts happening almost on its own.

So it was never willpower. You were handed a way of eating built to leave you hungry, then told that when you couldn’t stick to it, you’d failed. That’s backwards. You didn’t fail. The plan failed you.

So where did that tiny target come from?

Not from your body. The famous low-calorie figure women get handed traces back to a 1918 diet book. It has nothing to do with what a grown woman’s body actually needs. It’s close to what a toddler runs on, and your body at complete rest already needs more than that. The number your calculator gave you came out higher because it’s honest. And two levers are what make it work:

  • Protein keeps you full and protects your muscle, so you’re reshaping, not just shrinking.
  • Real food. In a careful study, people eating whole food naturally ate less than on processed, at the same fullness, without even trying. Your appetite does the counting for you.

Eating more of the right food isn’t what undoes your progress. It’s what makes it stick.

How it actually works

So if the number isn’t the whole story, what actually changes your body? Two things, and neither one is “eat less.”

Whole food does the heavy lifting on its own.

When most of what you eat is food your grandmother would recognise, meat, eggs, fish, yoghurt, veg, real bread, your appetite settles. You get full on less without counting, because real food is hard to overeat. That isn’t discipline. It’s just what whole food does. (It’s the whole idea behind the free guide below.)

Strength training reshapes what’s underneath.

This is the part the scale can’t see. Eating less can make you lighter, but lighter is often just a smaller version of the same shape. Lifting builds the muscle that gives you shape, supports your metabolism, and lets you eat more while staying lean. That’s the difference between shrinking and actually changing.

Put them together, eat whole food with protein, lift, and give it a bit of time, and the number in your result above stops being a limit you fight and becomes the amount that quietly works.

That’s the whole mechanism. No magic, no gimmicks, no eating windows. Just the two things that have always worked, done in a way you can actually keep up.

The Coach Sammi Method

Everything you’ve just read has a name.

The Coach Sammi Method is my approach to women’s weight loss and body recomposition, built on four things that actually work: progressive strength training, whole-foods nutrition, sustainable habits, and the mindset to keep them going.

No crash diets. No bootcamps. No starving. The nutrition runs on whole foods with short ingredient lists, grounded in evidence instead of whatever’s trending. The training builds strength, not punishment. And the habits are simple enough to survive a real week, work, kids, Friday night takeaway and all.

I didn’t learn this from a textbook. I built it on myself first, losing 30kg and keeping it off, then refined it coaching women here in Perth. It’s since helped 50+ Australian women lose weight without starving for it, and keep it off.

That’s the method behind the number you just got.

01

Progressive strength training

Lifting that builds week on week, so your body keeps changing and the metabolism that drives it keeps ticking over.

02

Whole-foods nutrition

Whole foods with short ingredient lists. Enough to feel full and fuelled, without weighing or counting every bite.

03

Sustainable habits

Small, repeatable routines fitted to your real week, so progress survives a bad day instead of unravelling.

04

Mindset

Ending the all-or-nothing cycle for good, so this becomes how you live rather than a thing you start again on Monday.

The free guide

Your number tells you how much. This tells you what.

The calculator gave you a starting point. Eat Without Rules is the simplest way I know to hit it without weighing a thing: one filter that replaces every diet you’ve ever quit. No weighing, no counting. Inside:

  • The one filter that tells you what to eat in three seconds.
  • The plate formula you build every meal from, and genuinely can’t get it wrong.
  • The palm method for hitting your protein, without weighing your food.
  • Room for a few wines and a Friday night takeaway, once a week, not a free-for-all.

Good questions

Common questions

Most women lose fat on more than they expect, not less. Your exact number depends on your age, size and activity. Use the calculator above to get yours, then adjust after two to three weeks.

For most adult women, that's lower than they need and hard to keep up. It's below what many women burn just at rest, so it tends to backfire: hunger wins, and you lose muscle in the process. A moderate, more generous intake is usually both kinder and more effective. Use the calculator above to find a starting point that fits you.

No. The number is training wheels. Once you learn what a balanced, protein-rich plate looks like, your appetite does the work. Most women count for a few weeks to calibrate their eye, then stop.

Roughly 0.25 to 0.5kg a week for most women, up to about 1% of your body weight. Faster isn't better. Slower loss protects muscle and is far easier to keep off.

A useful range is about 1.6 to 2.2 grams per kilogram of body weight a day. It keeps you full and protects muscle while you lose fat. The palm method, a palm of protein per meal, gets you close without weighing.

No. Protein is the only number worth tracking, because it keeps you full and protects muscle while you lose. Build the rest of the plate from whole food, half veg or fruit, a fist of carbs, a little fat, and it largely sorts itself out.

Often because you've eaten too little for too long: hunger wins, you can't sustain it, and lost muscle lowers what you burn. Eating a bit more of the right food, with protein and strength training, usually restarts progress.

Either. They measure the same thing. Australian labels use kilojoules; one calorie is about 4.2 kilojoules. The calculator above shows you both.
