I'm not sure why I failed to address this, I must have had a hot bath run and not wanted it to get cold so I rushed. I don't know if I've mentioned it before, but I love baths, especially if it's Friday and I can soak with a glass of Merlot.
Saying that, my baths haven't been quite the same lately. Joanne doesn't work as late on Fridays anymore, but rather than respecting my ritual, she has this horrible habit of disrupting my peace to come waffle about cushions, cats or whatever other rubbish she's been thinking about during the day.
Speaking of Joanne, yesterday she told me I get distracted too easily and should focus more on what I'm doing. I have no idea what she meant, but anyway what were we talking about?
That was it! Gaining weight, why does it happen?
There are two reasons why you may gain body fat:
- Too many total calories: Calories are energy and if we consume more energy than we need it will get stored as body fat to be used at a later date. This is as true for protein and fat, as it is carbohydrates, it's just that we need a lot more protein and fat, so you are less likely to overeat these macronutrients.
- Too many carbohydrates: All calories are not the same though, so even if your total calorie intake is less than what you need but too high in carbohydrates then you may gain fat, or at best, not lose any. We use carbohydrates for energy, to fuel our exercise and any movement we do, if we don't use more than we take in, then it gets stored as fat. For example if a person eats 800kcal of carbohydrates, but only uses 500kcal moving about during the day, then the excess 300kcal will be stored in our fat cells. There is no other option. Carbohydrates cannot do the job other other macronutrients (fat and protein). This means that even if you didn't eat enough protein and fat during the day, you're extra 300kcal of carbs is still getting stored as fat. However this is not the same for fat. Fat can be used as energy to fuel our movement (so can protein, but this is less desirable), so if a person only ate 200kcal of carbohyrates, but used 800kcal in movement, then the 600kcal difference can be made up from excess fat intake. If they did not consume sufficient fat in their diet either, then body fat would be metabolised to make up the difference. This is why lower carbohydrate diets are a lot more successful than low calorie diets. All calories are not equal.
