Why Do Some People Gain Weight on the Same Calories?

2 min readBy Nutritionist Nema Seeboruth

One thing that’s always fascinated me is how differently our bodies respond to food.

I’ve seen two people with almost identical lifestyles. They eat similar meals, have similar activity levels, yet one maintains their weight effortlessly while the other struggles to lose even a few kilograms.

At first glance, it doesn’t seem fair.

Most of us grow up believing weight management is simple: eat less, move more. And while that’s certainly part of the picture, it doesn’t explain why the results can be so different from one person to another.

So I started asking a different question. What if it’s not just about how much we eat, but how our bodies process what we eat?

When eating less stops working

Many people eventually reach a point where cutting calories no longer seems to help. They skip meals, avoid their favourite foods, and spend more time exercising. The scale might move at first, but after a while, everything slows down.

It’s frustrating because they’re putting in more effort than ever, yet seeing fewer results. The truth is, our bodies are designed to adapt.

When we consistently eat too little, the body can become more efficient at conserving energy. At the same time, blood sugar fluctuations may increase hunger and cravings, making it even harder to stay on track.

That’s why weight management isn’t always as straightforward as calories in versus calories out.

There’s more happening inside your gut than you think

Over the past few years, scientists have uncovered something really interesting. The bacteria living in our gut don’t just help digest food; they also communicate with our metabolism.

Together, these microbes form the gut microbiome, which plays a role in how our bodies use energy, regulate fat storage, and respond to the foods we eat. This could help explain why some people are more likely to store excess body fat even when they’re making healthy choices.

One area researchers are particularly interested in is visceral fat, the fat that surrounds our internal organs. Unlike the fat just beneath the skin, visceral fat is more closely linked to metabolic and cardiovascular health risks.

Supporting metabolism in a smarter way

One ingredient that caught my attention is Bifidobacterium animalis subsp. lactis BPL1, a heat-treated postbiotic used in Meta Boost.

What I find interesting is that its focus isn’t on helping people eat less. Instead, research suggests it may help support metabolic pathways involved in body composition and fat storage, particularly visceral fat.

Rather than relying on stricter diets or endless calorie counting, it’s about giving your metabolism the support it needs to function more effectively.

Looking at weight management differently

The next time you find yourself thinking, “Maybe I just need to eat even less,” take a moment to consider another possibility. Could your metabolism simply need better support?

Healthy eating, regular exercise, quality sleep, and stress management will always be the foundation of good health. But understanding your gut adds another piece to the puzzle.

Because sometimes the goal isn’t to fight your body harder. It’s to understand how it works and give it the support it needs to do what it was designed to do.
