Is A Calorie Is A Calorie?
There are many ridiculous myths in nutrition.
The "calorie myth" is one of the most pervasive...and most damaging.
It is the idea that calories are the most important part of the diet, that the sources of those calories don't matter. "A calorie is a calorie IS a calorie," they say... that it doesn't matter whether you eat a 100 calories of candy or broccoli, they will have the same effect on your weight.
It is true that all "calories" have the same amount of energy. One dietary Calorie contains 4184 Joules of energy. In that respect, a calorie IS a calorie.
But when it comes to your body, things are not that simple.
The human body is a highly complex biochemical system with elaborate processes that regulate energy balance.
Different foods go through different biochemical pathways, some of which are inefficient and cause energy (calories) to be lost as heat.
Here are 6 proven examples of why a calorie is NOT a calorie.
1. Fructose vs Glucose
Even though fructose and glucose have the same chemical formula, fructose has much more negative effects on hormones, appetite and metabolic health.
2. The Thermic Effect of Food
Protein calories are less fattening than calories from carbs and fat, because protein takes more energy to metabolize. Whole foods also require more energy to digest than processed foods.
3. Protein Kills Appetite and Makes You Eat Fewer Calories
Increased protein can lead to drastically reduced appetite and cause automatic weight loss without the need for calorie counting or portion control.
4. The Satiety Index
Different foods have different effects on satiety and how many calories we end up consuming in subsequent meals. This is measured on a scale called the Satiety Index.
5. Low-Carb Diets Lead to Automatic Calorie Restriction
Low-carb diets consistently lead to more weight loss than low-fat diets, even when calories are matched between groups.
6. The Glycemic Index
Studies show that refined carbohydrates lead to faster and bigger spikes in blood sugar, which leads to cravings and increased food intake. ~ galapagoswillin
