So, me and my best friend have very different body types. We both were a bit chubby as kids, and have grown out of it. About 2 years ago we were aprox. the same height and weight. Now she’s super skinny and I’m still chubby. We do work out together, do the same exercises, eat mostly the same (We mealprep together) and we have the same job that requires the same level of movement.
​
How come she’s super skinny and I’m chubby? I know its got something to do with metabolism, but how does that work exactly? How come one metabolism is faster than the other?
In: Biology
There is scientific evidence that having an over weight mom while being in the womb can impact your metabolism for the rest of your life, could that be the case for you?
Also, could she be doing more when you aren’t with her? You should bring up that she lose weight and you didn’t, and find out if she is doing anything extra you could try.
Weight gain or loss is mostly a factor of calories consumed.
If you both eat the same amount of calories, and all other factors being equal, then you will both either gain, maintain, or lose the same amount of weight. She already has less on her. If you want to get down to that weight, you’ll have to eat LESS than her for a significant amount of time. And it’s super-easy to cheat. Realize that one brownie is equivalent to running a 10-minute mile.
It’s mostly calories consumed. But there are indeed a whole number of other factors. You’ve covered exercise, which takes a LOT to burn significant calories. Body size upkeep for more mass takes more energy. Some is genetic disposition to body types. Your genes dictate where extra energy prefers to get stored. For men it typically goes around the belly. For women it’s typically the thighs. But that doesn’t magically generate more energy. Genes and upbringing plays a factor into natural eating habits. Times of sickness often lead to weight loss because your body is using more energy fighting off the plague or whatnot.
And then there’s the thyroid. Which is the engine control of your body. Your engine can idle high or low. She might have hyperthyroidism or you might have hypothyroidism to various degrees. If she seems more energetic and you seem more sluggish or tired, then that could easily be it. She’s simply burning more calories through the day simply existing.
Interesting question, first of all metabolism refers to all the chemical processes in your body, so a faster metabolism mean a faster use of energy so need more food. If as you said you live in the same way of your friend, your metabolism could be slower for some reason:
-The saddest could be that a lot of people are born with a better metabolism;
-Drink more water (it could help your metabolism to get faster);
-Eat protein ([https://pubmed.ncbi.nlm.nih.gov/15507147/](https://pubmed.ncbi.nlm.nih.gov/15507147/));
-Get good sleep;
– Genes definitely play a role in muscle size and your ability to grow muscles, both of which affect your metabolism;
And the last thing, metabolism is not only useful for lose weigh it also guarantee a good life, our brain have is own metabolism called “Brain metabolism”, that consume a lot of Glycogen, glycogen is the main body energetic resource, if it is too high it will be transformed in fat, so do a lot of mental activity will help your metabolism to get faster, and help you in a lot of other things
