Losing weight is challenging, and maintaining weight loss over the long term is even harder. Millions of people attempt weight loss programs each year, but the majority end up regaining the weight over time. My clients are often surprised that I don't tend to discuss calories with them. However, research increasingly suggests that calorie counting is highly ineffective.
The Pitfalls of Calorie Counting
On the surface, calorie counting appears logical: consume fewer calories than you expend, and you will lose weight. However, this simplistic equation does not account for the complexity of human metabolism and behaviour:
Inaccuracy in Calorie Measurement
The calorie content on food labels is often an estimate. Food manufacturers can be up to 20% off in their calorie counts, meaning a "100-calorie" snack might contain anywhere from 80 to 120 calories. Also, portion sizes are difficult to measure precisely, and estimates can vary by more than 50%. In addition, cooking methods affect calorie content. For example, a raw stick of celery has about 6 calories, but when cooked, it can contain six times that amount.
Variability in Calorie Absorption
When we look closely at almonds, almond butter, and almond oil, the number of calories listed on nutrition labels may appear identical or very similar. However, the calories your body actually absorbs differ significantly due to food structure and digestion. Whole almonds have a tough cell wall (the "fat matrix") that isn't fully broken down during digestion, so approximately 20-30% fewer calories are absorbed compared to what's listed on the label. For instance, a 170-calorie serving of whole almonds might only result in around 120-135 calories actually absorbed. In contrast, almond butter has already been mechanically ground, partially breaking down these cell walls and allowing greater calorie absorption—typically, you'll absorb almost all of its calories. Almond oil, being completely free from any structural barriers, provides full calorie absorption, with your body utilising practically every calorie consumed. Understanding this difference explains clearly why not all calories are created equal and why considering food structure matters in weight management.
Macronutrient Quality Matters More Than Calories
Studies show that high-protein and/or low-carb diets lead to greater weight loss than low-fat diets, even when calorie intake is similar. This is because the source of calories is crucial; 100 calories of soda and 100 calories of avocado affect the body differently.
Calorie Counting and Disordered Eating
Calorie tracking can lead to obsessive behaviours and increase the risk of disordered eating. A 2017 study found that 75% of participants with eating disorders said calorie counting apps worsened their symptoms.
It Ignores Hunger Signals and Satiety
Relying on calorie counting often disconnects you from your natural hunger cues. You might find yourself eating even when you're not hungry simply because you have calories left, or feeling constantly deprived because you've reached your limit for the day. Over time, ignoring your body's hunger signals leads to confusion, binge-eating episodes, and unhealthy eating patterns.
It promotes Yo-Yo Dieting
Restrictive diets that rely on calorie counting often lead to yo-yo dieting, which has significant negative effects:
Increased body fat percentage over time.
Slower metabolism, making future weight loss more difficult.
Higher risk of type 2 diabetes and cardiovascular disease.
A Sustainable Alternative to Calorie Counting
Instead of focusing on calorie restriction, a better approach is to prioritise nutrient-dense, whole foods and lifestyle changes
Eat whole, unprocessed foods.
Prioritise protein and fibre to regulate appetite and keep you full longer.
Focus on meal timing.
Slow down eating and listen to hunger cues.
Stay hydrated.
Support gut healthy with variety of plant foods and some fermented foods.
Move more.
Get enough sleep & manage stress
