You do not need to weigh every meal, hit perfect macros or live inside a calorie-tracking app for the rest of your life.

But “without dieting” does not mean “without any structure”.

If your goal is to lose body fat, your eating still needs to create an energy deficit over time. You can get there by tracking calories, changing portions, repeating a few reliable meals, reducing the extras that add up quickly, increasing your activity or using a combination of those things. Your body does not require the method to have a name.

What matters is whether the method creates the result and whether you can keep doing it for long enough.

I learnt the extreme end of this through natural bodybuilding. With enough precision, I could deliberately change my body. I also learnt that being able to follow a very strict diet does not mean I want to live that way all year—or that someone with a full-time job, a family and different priorities should have to.

That is the real goal of dieting without dieting: use enough structure to learn what works, then make that structure easier to live with.

Watch Karl's original talk about calories, macros and building a more liveable routine.

Fat loss still has a cost

There are plenty of ways to organise a diet. Low carb can work. Low fat can work. A fixed meal plan can work. Flexible tracking can work. A healthy low-fat diet and a healthy low-carbohydrate diet produced similar average weight loss in the 12-month DIETFITS randomised trial (opens in a new tab).

That does not mean every approach works equally well for every person. It means there is no single magic split of protein, carbohydrates and fat that removes the need for a consistent energy deficit.

Food quality still matters. It affects your health, hunger, training, energy and how easy the plan is to follow. But a nutritious food can still contain more energy than you realise, and a favourite food does not automatically stop fat loss. The full pattern matters more than the moral label you put on one meal.

The larger or faster the result you want, the more precision and sacrifice it will usually require. That is not punishment. It is a trade-off. You can choose a less rigid approach and still make meaningful progress, but the timeframe may be slower and less predictable.

Do not use somebody else’s calorie target

One of the biggest problems in the original video is the idea that 2,000 calories is a sensible starting point for everyone. It is not.

The 8,700 kJ figure used in the Australia New Zealand Food Standards Code (opens in a new tab) is an average-adult reference for calculating daily-intake percentages. It is not your personal maintenance target. Your needs are influenced by your size, age, sex, activity, training and individual response.

Basal metabolic rate is also not the same as maintenance calories. It estimates the energy required at rest. Your total daily expenditure also includes normal movement, deliberate exercise and the energy used to digest food.

A calculator can give you a starting estimate. Even the US National Institutes of Health Body Weight Planner (opens in a new tab) asks for personal details and physical activity rather than assigning one number to everybody. The estimate still needs to be tested against what happens in real life.

This is why I prefer a short calibration phase rather than pretending the first number is perfect.

Stage one: collect useful information for two weeks

For about 14 days, make the important parts of your routine reasonably consistent. This is a KZPT coaching method, not a scientific requirement or a test you can pass or fail.

You might:

  • keep breakfast and lunch fairly repeatable;
  • measure oils, sauces, spreads, snacks and drinks that are easy to underestimate;
  • include a clear protein source in each main meal;
  • keep your normal training and daily movement reasonably consistent;
  • record what you eat in an app, notes or a simple meal checklist; and
  • monitor your morning body weight if weighing is appropriate for you.

The point is not to eat perfectly. The point is to make the information clear enough to learn from it.

Daily scale readings can move because of fluid, sodium, carbohydrate intake, digestion, training and other normal factors. Do not reward or punish yourself for one number. Look at the weekly trend alongside what you actually did.

If weighing or food tracking increases anxiety, guilt or compulsive behaviour, this method is not the right tool. Use a lower-detail approach and speak with an appropriate health professional if you need support.

At the end of the two weeks, ask:

  1. Was the average trend moving in the intended direction?
  2. Which meals kept me satisfied and were easy to repeat?
  3. Where did unplanned energy tend to enter the week?
  4. Did my training performance and recovery hold up?
  5. What part of this routine could I realistically continue?

You are not trying to measure your metabolism in a lab. You are building a practical working estimate of what your current routine produces.

Stage two: keep the structure and reduce the admin

Once you understand the pattern, you may not need to track every ingredient every day.

Keep a small library of meals you have measured accurately once. Use similar ingredients and portions most of the time. Change the flavours, vegetables or protein source so the routine does not become miserable, but keep enough consistency that you still know roughly what you are eating.

A simple meal can contain:

  • a useful serve of protein;
  • vegetables or fruit;
  • a portion of carbohydrate that suits your activity and target; and
  • a deliberate amount of dietary fat rather than an unmeasured pour.

That is not a compulsory plate formula. It is a practical way to make meals filling, nutritionally useful and easier to adjust.

Australian guidance recommends a varied pattern built mainly from the five food groups, with small amounts of unsaturated fats and fewer energy-dense discretionary foods. You do not need to ban a burger, dessert or meal out. You do need to understand that its portion and frequency still count.

Plan for the weekend before it arrives. If Friday night, alcohol, takeaway or social meals repeatedly erase the structure from Monday to Thursday, that is not a character flaw. It is the part of the plan that needs attention.

Give protein and strength training a clear job

During fat loss, the goal is not only to make the scale lighter. You generally want to reduce body fat while maintaining as much muscle, strength and function as you reasonably can.

Protein and resistance training help with that job. In one randomised trial, young men completed a large energy deficit and high-volume training program. The group eating 2.4 grams of protein per kilogram per day gained more lean mass and lost more fat than the group eating 1.2 grams per kilogram. That is useful evidence that higher protein can help in a demanding fat-loss phase, but it is not proof that everyone needs 2.4 grams or should copy that program.

For context, the Australian Recommended Dietary Intake for generally healthy adults is lower and is intended to cover basic nutritional needs, not to prescribe the best intake for every resistance-trained person losing fat.

My coaching preference: where it suits the person, I often use a higher-protein target around 2 grams per kilogram per day during a fat-loss phase. It is not a universal minimum. Body size, diet, health, training, food preferences and tolerance all matter, and some people need an individualised approach.

You do not need to force protein higher at the expense of a balanced diet or treat carbohydrates and fats as the enemy. Dietary fat is important, but there is no universal rule that every person must eat exactly one gram per kilogram. The Australian Dietary Guidelines (opens in a new tab) support small amounts of unsaturated fats from foods such as nuts, seeds, fish, avocado and oils including olive and canola.

For activity, the current Australian movement guidelines (opens in a new tab) recommend muscle-strengthening work on at least two days per week as part of a broader active week. More is not automatically better. Use a training dose you can recover from and perform consistently.

Build a feedback loop, not another set of rules

The useful part of data is not the number itself. It is the decision the number helps you make.

Review two to four weeks of trends rather than one meal or one weigh-in. If your body weight, measurements, photographs, clothing fit and training data are all moving the way you want, keep going. You do not need to “optimise” a plan that is already working.

If the trend is not changing, first check whether the routine you planned is the routine you lived. Then change one clear lever:

  • reduce a portion you barely notice;
  • measure an oil, sauce or snack that has been drifting upwards;
  • change a regular high-kilojoule drink;
  • make one meal more filling with protein, vegetables or fruit; or
  • add a realistic amount of walking or other activity.

Do not slash food, add hours of cardio and remove every enjoyable meal at once. You will not know which change mattered, and the new plan may be much harder to sustain.

As body weight falls, energy needs can also fall. That does not mean your metabolism is “broken”. A smaller body generally requires less energy, and additional metabolic adaptation can occur during weight loss. If progress genuinely stalls across several weeks, reassess the inputs and make the smallest useful adjustment.

You have agency, not total control

The video says food and movement are completely within our control, even with work or a baby. I would not put it that way now.

Your health, work, finances, family, sleep and environment can all affect the choices available to you. Pretending those things do not matter usually creates guilt, not a better plan.

You still have agency. Your decisions still influence the result. The useful question is not, “Why can’t I be more disciplined?” It is, “What can I reliably do in this phase of life, and what result can that realistically support?”

Sometimes the answer is a highly structured fat-loss phase. Sometimes it is slower progress. Sometimes maintaining your current weight while life settles is the smarter result.

That is still control. It is control with context.

The next meal matters more than the mistake

I know how to diet with a lot of precision. I also know how much I dislike living in that mode.

What makes the biggest difference is not avoiding every imperfect meal. It is getting back to the next useful decision without turning one choice into a lost day, weekend or month.

You do not need a “cheat day”. You do not need to earn food. You do not need to punish yourself with extra cardio.

Learn what your normal choices produce. Keep the parts that work. Adjust the parts that do not. Match the structure to the result you genuinely want and the life you genuinely have.

That is how you stop starting diets and start building a way of eating you actually understand.
