  • As followers of this channel know, I'm an advocator for calories in and calories out

  • paired with macro counting and exercise for weight management.

  • But, rising research of low-carb diets are beginning to blur our understanding of energy

  • balance.

  • Subsequently, it created two opposing groups of believers in the matter, sparking heavy

  • debate and scrutiny on both sides.

  • The battle of low-carb vs energy balance continues today, and it has been so intense that even

  • I have come to question the foundation of calories in and calories outehh, not entirely.

  • But this video is not about that debate, because frankly, regardless of what stance I take,

  • it won't ever satisfy everyone.

  • That being said, low-carb diets DO seem to have more weight loss benefits than most other

  • diets.

  • For those not too familiar with low-carb diets, the concept is quite simple:

  • Consume fewer carbs.

  • In many cases, 50 grams of carbs or fewer per day, at least for those aiming for Keto,

  • which is only about 2 medium-sized apples.

  • Although it sounds like quite an undertaking, going low-carb also means you're allowed

  • to eat a lot more protein and fat.

  • The mountainous carby mash potatoes go down, but protein steaks and delicious fatty butters

  • go up.

  • It certainly makes the carb limitationeasier to digest, pun intended.

  • But, what else makes it better than other diets for weight loss?

  • One thing that many people initially experience when going low-carb is an immediate drop in

  • water weight via the reduction of the water-retaining carb our body uses known as glucose and its

  • stored form glycogen.

  • Obviously, this is not exactly the fat weight you're hoping to lose, but this can be motivational

  • for those easily swayed by the number on the scale.

  • Not exactly my favorite measurement tool, but alas, for many it is.

  • The lack of carbs also promotes the state of Ketosis, as many of you already know.

  • Along with some of the benefits outlined in my keto video, being in ketosis via low-carb

  • dieting has been associated with the suppression of the hormone ghrelin, making you feel full

  • quicker.

  • Butthe majority of weight loss benefits might not actually be related to the lack

  • of carbs.

  • If anything, it comes down to fact that you're eating more protein.

  • Out of the three macronutrients, protein is the only one to show consistent positive effects

  • on weight loss.

  • And it comes down to protein's effect on three factors: satiation, thermogenesis, and

  • total food intake.

  • When it comes to satiation, almost always, more protein makes study subjects feel fuller

  • with fewer calories.

  • A 2005 study showed that the satiating effect of protein is so strong that it was able to

  • decrease energy intake by 441 calories per day, hypothetically equating to nearly one

  • pound lost per week.

  • It's hypothesized that this might be due to an increased sensitivity to leptin, the

  • hormone that inhibits hunger, when consuming more protein.

  • In terms of thermogenesis, protein is beneficial to weight loss under thermic effect of food.

  • Thermic effect of food is generally defined as the amount of energy it takes for the body

  • to process the food you eat.

  • Carbs and fat tend to have a 5 to 15% thermic effect.

  • Protein, on the other hand, has a notably higher thermic effect of 20-35%.

  • That means for 500 calories of carbs or fat you consume, it takes roughly 25 to 75 calories

  • to digest it.

  • 500 calories of protein, however, will take 100 to 175 calories.

  • Short term, not that big of a dealbut in the long run, it can add up to a significant

  • number of calories burned, thus more weight loss.

  • Finally, with total food intake, it comes down to limiting the desire to eat, aka satiety.

  • Unlike satiation, where you feel full quicker, satiety means you feel satisfied longer.

  • The benefit of this is that it might reduce the amount of food you eat later.

  • One study found that, subjects that had a low protein lunch consumed 811 calories during

  • dinner.

  • High protein group, however, consumed only 438, almost half as much!

  • Similar to keto, protein-induced satiety is related to the hormone ghrelin, which regulates

  • appetite.

  • Now, as we can see, if there's any reason to take up a low-carb diet outside of ketosis,

  • it's because it naturally promotes eating more protein!

  • Of course, it's still important to make sure not to get too much protein, as it can

  • present a myriad of issues, just as overconsumption of fats and carbs will.

  • But the main takeaway is that low-carb diets can work regardless of its primary function.

  • And it still doesn't go against the science of calories in and out.

  • More protein means more calories burned and fewer calories consumed.

  • Just like how it should be.

  • But, if it's true that there's other potential weight loss benefits that we're not yet

  • privy to when it comes to low carb diets, it only stands to become an even stronger

  • weight loss tool.

  • But that's a debate for another day

  • For now, let me know your opinion on the matter.

  • Share your experiences with low carb or keto diets in the comments below, or comment if

  • you think that all of the factors I've mentioned still isn't reasonable enough for using

  • low-carb diets.

  • As always, thank you for watching!
