Slow-digesting carbohydrates: diet and how much you need
A diet based on slow-digesting carbohydrates sounds like a simple answer: eat less sugar, choose foods that provide steadier energy, and the scales start to move. But the real question is the same as it was years ago: how much carbohydrate do you actually need?
One person does three easy workouts a week, another runs long distances, and a third spends much of the day sitting at a desk. The same carbohydrate intake cannot suit everyone equally well.
Slow-digesting carbohydrates and an old debate
Carbohydrates are often debated as though there must be one right answer. Some nutrition guidelines suggest that carbohydrates should account for 50% or more of total calorie intake. Recommendations for lower-carbohydrate diets range from 40 percent down to almost zero, particularly for ketogenic diets.
Frankly, percentages alone are not much help. Whether someone says that 45% of your calories should come from carbohydrates or puts the figure at 65%, one practical question remains: how many grams does that actually mean on your plate?
That is why it makes sense to look at carbohydrate intake in terms of grams for one kilogram of body weight, or g/kg. This makes the discussion more concrete, especially if your goal is not simply to “eat more healthily” but to maintain your body weight, lose fat, or train without losing strength.
What actually determines your carbohydrate needs?
The simple truth is that your carbohydrate needs depend on your activity. If your day is fairly quiet and you do little training, your body does not expend as much energy as that of someone who does long endurance workouts or several hard gym workouts a week.
A typical low-carbohydrate or ketogenic diet may contain up to 1 gram of carbohydrate for one kilogram of body weight. That is quite a low intake, and it does not suit everyone, particularly if your training load is higher.
A typical moderate-carbohydrate diet, such as the Zone Diet or Duchaine’s isocaloric diet, contains, on average, up to 2 grams of carbohydrate per 1 kg of body weight, sometimes slightly more. This may be a more sensible starting point if you do not want to cut your intake too low but do not need the amounts an athlete would consume.
A typical high-carbohydrate diet contains 4.5 – 6.5 grams of carbohydrate per 1 kg of body weight. For endurance athletes, the recommendation may be 6 – 8 g/kg. For carbohydrate loading, recommendations have even reached 10 – 16 g/kg.
A diet based on slow-digesting carbohydrates in practice
So what actually happens when you choose slower-digesting carbohydrates? Usually, your eating habits become more settled: less snacking on sweets and more whole grains, legumes, vegetables, and other foods that keep you feeling full for longer.
This does not mean that all fast-digesting carbohydrates are bad or that slow-digesting carbohydrates solve everything. During a workout, readily available energy can have its place. On a rest day or at the end of a sedentary working day, the same amount may no longer be such a good fit.
A good starting point is to look at three things: changes in body weight, hunger, and workout quality. If your weight is not changing, you have no energy, and your performance falls apart during workouts, you may be eating too little carbohydrate. If your weight is rising quickly and your meals consist mainly of flour-based foods and sweets, either the amount or your food choices may be wrong.
When should you choose fewer carbohydrates?
A lower carbohydrate intake may suit you if your goal is fat loss, your daily activity is modest, and you feel good eating fats and protein. You do not have to cut carbohydrates to zero straight away. Sometimes, simply cutting out sugary drinks, pastries, and constant snacking is enough.
When do you need more carbohydrates?
You often need more carbohydrates when your training is long, frequent, or very intense. Particularly in endurance sports, there is little point in stubbornly keeping your carbohydrate intake too low. Your body will usually let you know: your pace drops, recovery takes longer, and your mood suffers.
Carbohydrates: what should you monitor?
There is no single universal answer. So who is right? In the spirit of the original article, you could say that the person who considers the individual, rather than just a chart, is right.
Your goals, the level and type of physical activity you do, genetics, appetite, sleep, and your ability to stick to your diet all matter. If a plan looks good on paper but leaves you ravenous by the evening, it is not a good plan.
The practical advice is to start with a moderate intake. For a few weeks, pay attention to how much carbohydrate you actually eat, rather than simply whether a meal seems “healthy.” It will then be easier to decide whether you need less, more, or simply better choices.

FAQ
Is a diet based on slow-digesting carbohydrates suitable for everyone?
Not necessarily. It may work well if you want a more stable appetite and easier weight management, but a very active athlete may need more carbohydrates and sources that provide energy more quickly.
Do you have to avoid carbohydrates to lose weight?
No. Weight loss depends on your choices throughout the day and your energy balance. Reducing carbohydrates can help if it makes eating simpler, but it is not the only way.
Are percentages or g/kg a better measure?
g/kg is often more practical because it relates the amount to your body weight and needs. A percentage can be useful for an overview, but without an amount in grams, it remains too vague.
