weight gain

Wegovy and Ozempic, both GLP-1 agonists, have taken the world by storm, providing a simple way to lose weight without changing our lifestyle. A new report in Science helps us understand what we do not know: the known unknowns of obesity. Let me summarize.
When trying to identify why many young children gain weight at an early age, schools often are criticized. But a new, large study indicates that schools are being unfairly implicated in this regard, and that significant weight gain is taking place at home -- specifically, during summers away from school.
It's widely believed that a low basal metabolism predisposes a person to weight gain and obesity. And it makes sense since a low BMR can be a substantial part of a sedentary person's energy expenditure. But a recent study couldn't find such a connection, so the old I'm fat because I have a slow metabolism excuse won't hold water, at least according to this study.
A controversial recent hypothesis is that the use of non-nutritive sweeteners can lead to obesity because they "uncouple" the sense of sweetness from calorie intake. But a recent study failed to replicate the work on which that theory rests. So once again, calories count!
Forget the no-fat, no-carb and no-sweets diets. Portion control could be the real game changer for losing and/or maintaining weight, and it also might well be a key player in combating obesity. According to a recent study, large meal portions consistently lead to overeating, which leads to weight gain.
Every now and then someone says, "Calories do not count. Some foods are more fattening than others." This statement is not quite correct, calories do count. However, recent scientific evidence suggests that the calories from some foods are more fattening than from others. How can this be? Let's take a look at the calorie content of different foods, and how these calories are used in our body.
