So, the participants’ greater weight loss can be explained by their lower calorie intake (not directly the type of calories). When people eat more protein, they feel fuller and eat fewer calories without realising it. By excluding carbs, the low-carbohydrate dieters ended up eating more protein. However, when you look more closely, these studies were conducted under ‘free-living conditions’ which means participants were free to choose what and how much they ate. Their argument comes from studies that show greater weight losses from low-carb diets compared to high-carb diets, despite the participants claiming to eat the same calories. calories from carbs are ‘bad’ as they can be turned into body fat more readily than ‘good’ calories from protein or fat. “To lose weight, you need to be in a state of negative energy balance,” clarifies exercise physiologist and nutritionist Dr Scott Robinson ().Ĭan eating ‘good’ calories instead of ‘bad’ calories help you lose weight? Some people claim that you can lose weight without a calorie deficit.įurther, they claim you can lose more weight on the same calorie deficit by avoiding carbohydrate, i.e. Conversely, when people eat more calories than they need, they gain weight.
Indeed, studies using rigorous standards have consistently shown that when people create a calorie deficit, they lose weight. The calories burned cycling won't differ depending on what you eat, but good nutrition will make a difference to your performance “Long-term changes in mass are generally proportionate over time to the net balance between energy in and out.” “There’s no doubt that energy (calorie) balance - represented as calories in versus calories out - matters when it comes to weight loss,” explains Dr James Betts, associate professor in nutrition and metabolism at the University of Bath. Others believe that no calories are alike, and that provided you choose the source of your calories carefully, then you can lose weight without having to count up your intake. Some believe that a calorie is a calorie no matter where it comes from: to lose weight people simply need to eat less and move more.
The question as to whether all calories are equal has been hotly debated by scientists for many years, and has proved to be a controversial topic. Ride hard and you’ll burn mostly carbohydrate, whereas at an easier pace you’ll burn a higher proportion of fat - all of which is explained in more detail below. The type and quality of food you eat can affect how quickly and efficiently you turn fuel into forward motion. Despite the onslaught of fad diets and related pseudo-science, weight loss is still a simple matter of calories in versus calories out, but that doesn’t mean you can eat whatever you like.
