Are You Eating Less but Gaining Weight?
It may seem incredible, but it's true: You're eating less but are gaining weight. How can this happen? What are you doing wrong? We'll try to answer these questions in today's article.
We all know people who eat a lot and are thin, just like we know people who eat less but are still gaining weight. The mystery lies in why the latter have difficulties maintaining their optimal weight. After all, it’s hard because they often experience feelings of failure and even guilt for not being able to lose weight, despite eating less.
The weight loss formula is practically universal. It’s based on the first law of thermodynamics and is actually quite simple. We lose weight when we expend more energy than we take in. This is scientifically proven and many people lose weight when they follow this principle. However, as with everything, this mathematical equation on its own won’t lead to good results because bodyweight has genetic, environmental, food, and psychological dimensions.
So, when trying to lose weight, you must take all of these into account.
Are you eating less but gaining weight?
It might be due to an energy imbalance
The foundation for maintaining energy balance is rooted in two concepts:
- The calories we eat through food are our daily fuel.
- The calories we use are our metabolic rate.
However, other factors come into play such as:
- Basal metabolism. The body requires minimum energy to perform its most basic functions. In fact, it represents about 70% to 80% of the total daily energy expenditure.
- Exercise and physical activity. These are the calories we spend doing daily activities or more intense physical exercise.
- The thermal effect of food. This is the energy we spend on food intake and digestion.
We gain weight when more calories are coming in than going out. On the other hand, we lose weight when more calories are going out than coming in. So, based on this, one of the most widespread ways to lose weight is to restrict calories. In other words, we eat less.
Ok, but what about people who are gaining weight even when they’re eating less? What in the world are they doing wrong?

The role of your metabolism
Our body loves balance in every sense. It has its own mechanisms to balance its pH, temperature, blood pressure and, of course, weight. When it detects an important caloric restriction with its consequent weight loss, it’s alarm bells go on. Thus, it goes into calorie-saving mode – completely against our will. So, a series of hormonal reactions activate to save energy. This happens automatically.
One of the first things that happen is there’s a decrease in the basal metabolism and the feeling of satiety. In turn, the hormones associated with hunger increase. As you can see, basal metabolism is of great importance in the total calories we consume throughout the day. So, in this case, we expend less even when we eat less and the weight just stagnates. In fact, it even increases in some cases.

Expending more to lose weight
So, eating less is a way to lose weight because we ingest fewer calories. However, as we mentioned above, we can’t just decrease our intake of calories uncontrollably, because then our metabolism becomes slower. Apart from having the opposite effect at the metabolic level, low-calorie diets lead to a lack of nutrients and energy. Thus, they can lead us to a state of apathy, decay, and even bad mood.
So, it’s more important to spend more energy instead of decreasing the calories we ingest. Physical exercise and daily activity are essential for maintaining a healthy metabolism, modulating the regulation of hormones positively, increasing muscle mass, and decreasing fat mass.
The importance of muscle mass
Our muscles are one of the body systems that most consume energy, even when we’re doing nothing. A person with a higher percentage of muscle mass will have a higher basal metabolism than a person with a lower muscle percentage. So, our muscle mass is usually affected as soon as we begin to restrict nutrients. For instance, the body will look for other sources of glucose when the body lacks what the food provides.
You may not know it, but one of the main reserves of glucose we have is body fat and muscle mass. And it’s precisely the latter that we use primarily when there’s a caloric restriction. The result is a loss of muscle mass that further decreases our energy expenditure.
At this point, we must reduce the amount of food we eat and it comes with the negative consequences we mentioned above. So, the reason why some people gain weight even if they eat little is that they’re burning so little it makes it difficult to eat less.
Paradoxically, sometimes eating less is not synonymous with losing weight. So the best thing you can do is put yourself in the hands of a professional and adopt healthy lifestyle habits that’ll allow you to lose weight and maintain a healthy new weight.
