Of course things are not so simple. Calories in/calories out partially applies to weight gain/weight loss, but it's not the complete story. Hormones also play a role.
That's why people start to gain weight as they grow old, even though they eat the same. It involves testosterone/estrogen and an enzyme called lipoprotein lipase.
- ngngngng 8y ago> It involves testosterone/estrogen and an enzyme called lipoprotein lipase. This is just a variation of the thyroid problem reasoning. Hormone changes with age or thyroid issues might change your resting metabolic rate over time by 100-200 calories per day (a single candy bar of calories). But that doesn't curse you to be fat, which is what I am trying to disprove. You will then need to adjust your intake/exercise level accordingly to the new resting metabolic rate.
- elbear 8y agoI didn't say that hormone changes lower your resting metabolic rate. They simply make your body be more inclined to store fat. The enzyme that I mentioned LPL, becomes more active and stores more fat. Have you ever wondered why men and women tend to put on weight differently? The same enzyme is involved. For men it's more active around the waist. For women, around the thighs. For a thorough treatment of this topic, I recommend the book Why We Get Fat by Gary Taubes. It goes into the biology of why we get fat. Note that it's pretty strong against carbs, so depending on your beliefs, you might not like it. Although, I have to say, it makes a pretty convincing case on why we should lower carbs intake.
