Why Weight Loss Isn’t About Calories (and never really was)

A calmer, more realistic way to think about weight and health

If calorie counting worked long term, most people wouldn’t feel stuck in cycles of restriction, hunger and regain. The weight loss problem isn’t lack of discipline. It’s that weight regulation is biological, not mathematical.

Calories Don’t Tell the Whole Story

Calories tell us how much energy a food contains — but they don’t tell us how that food affects:

Research shows that when people eat diets high in ultra-processed foods, they naturally consume more calories – even when meals are carefully matched for energy and nutrients. The body simply doesn’t register these foods in the same way as whole foods do. This isn’t about willpower. It’s about physiology.

Why Eating Less Often Backfires

When calories are aggressively cut, the body responds by:

This is why dieting so often leads to constant thoughts about food, snacking, or overeating later – sometimes months after the diet has ended.

Some metabolic researchers, including Dr Benjamin Bikman, focus on the role of insulin resistance here. While insulin isn’t the only factor in weight gain, there is good evidence that chronically elevated insulin levels and unstable blood sugar make appetite harder to regulate. The body is trying to protect itself.

A More Helpful Way to Think About Weight

Instead of asking ‘How can I eat less?’, a more useful question is: ‘How can I eat in a way that keeps me satisfied, steady and nourished?’

This usually means adding before subtracting. Large population studies consistently show that people who eat enough protein, plenty of fibre, mostly whole foods and regular meals tend to feel fuller, snack less and naturally regulate their intake – without tracking or restriction.

What ‘Enough’ Looks Like (In Simple Terms)

For weight loss, you don’t need to count everything – but having a rough sense helps.

Protein

Most adults benefit from around 1.0–1.2g of protein per kg of body weight per day (and more with age or higher activity). For many people, this works out at around 20–30g of protein per meal. Examples include:

Fibre

UK recommendations are 30g of fibre per day, yet most people average closer to 18g. Rather than counting grams, aim to include fibre at every meal:

Regular meals

Eating three proper meals a day helps stabilise blood sugar and reduces the urge to snack or overeat later. Try building meals that support your body:

Where seeds fit in

Rich in fibre, healthy fats and minerals, seeds help meals feel more satisfying and nutritionally complete. Adding them regularly is a simple way to:

Weight regulation works best when the body feels safe, fed and supported – not restricted.
