Why We Get Slow Metabolisms & Should You Reverse Diet? Science Discussion ft. Dr. Eric Trexler blue0eyes0knight: yes BMR/REE is related to body size with larger bodies associated with higher BMR requirements, but. the word metabolism seems to always be used in reference to BMR only. Remember metabolism encompasses total energy expenditure. NEAT which is a part of TEE/TDEE has been shown to vary significantly between individuals with leaner individuals generally displaying a greater degree of NEAT particularly in response to surplus calories/overfeeding. Therefore it is not necessarily incorrect for a lean person to say that they have a fast metabolism or for a fat person to say they have a slower metabolism. Take this example: individual 1 is 6ft 3, 200lbs and has a BMR of 2000 calories. Individual 2 is the same height but has 20lbs more fat mass and as a result of carrying the excess fat also has 4 lbs more muscle mass than individual 1 (which is often seen. Fat is metabolically active at around 2 calories per lb of fat per day, muscle is around 6. So the larger individual likely has a BMR that is 64 calories per day higher than the leaner individual (20 x 2= 40 and 4 x 6 = 24 so 40 plus 24= 64. BMR is not much higher in the larger individual as can be seen. Lets Assume exercise levels are similar and thermic effect of food would likely be similar (usually about 15% of calories ingested. The remaining component of TEE is NEAT which as i stated is highly variable. If you overfed both individuals the lean individual could easily burn 1000 calories through NEAT whereas the larger individual may only burn 500. There is a large genetic component to this and there are plenty of studies demonstrating this effect. As you can imagine the larger individual having a faster BMR by 64 calories is hardly relevant when the leaner individual has levels of NEAT 500 calories higher. Point being yes larger individuals have higher/faster BMR generally but overall they have SLOWER metabolisms.

I watch a lot of your content and I have a detailed question to make sure I am on the right track. My weight and eating habits were typical standard america diet (terrible) I ate to feel happy and satisfied. I ate a lot of pizza, nachos, fast food etc. I was 260 and tore my ACL. After surgery I went up to 280 and wanted to make a change and get strong and lean. I found keto which I did for 1 year with not much working out (here and there with no consistency. I got down to 196. I then went full carnivore eating a 1. 2 lbs ribeye every night and drinking bullet proof like coffee throughout the day. My weight settled at 200 for 6 months. Then I wanted to see progress so I started a consistent Mon-wed-fri workout plan lifting weights. I focus on compound movements and try to hit all muscles for at least 3-4 sets of 10. Squats, Dead lift, military press, dumbbell bench press etc. I did not change my food intake yet I have been doing this for 6 weeks now and gained 8 lbs. The amount I can lift has increased over the 6 weeks and my friend is just telling me I am putting on muscle which is why I am not losing fat. I do want more muscle so I look good when I lose the fat but I really want to lose more fat. Do I need to just continue and be more patient with the process? Is my metabolism just screwed and no longer in a deficit with my carnivore diet? I tried a couple re-feeds and each one made me gain another pound. I weigh myself each morning at same time each day. I do not get worried about 1-2 pounds cause of water weight but when I do not see progress after 10+ days I start to think I am doing something wrong. What would you suggest I do too start the fat loss? The first 80 lbs seems easy now as I feel I've hit a wall yet not I am doing more by adding a lifting regimen?

Dr. Trexler, I could say that you have it all wrong, but instead I'll just say that i'm much, much further ahead of you, which is more accurate. In my quick diet guide available on Amazon. com entitled The Three Day Delay Diet I show how if eating correctly, which almost no one does, people can lose 2 pounds with 10 minutes, at most, of moderate exercise, or even no exercise at all. This weight loss occurs on the third day after the exercise happens, with no weight loss in between, and can be repeated over and over again, until all the excess weight is lost. I'm sure you can understand how this shows that energy expenditure is irrelevant when talking about weight loss compared to how you and so many other people claim. Since the premise of a person's weight being tied to their caloric intake and expenditure is wrong, this is just the tip of the iceberg. Our bodies work a certain way. A way that your unaware of at the moment. The same way a video game only works one way if you want to beat the game. For you to say that the body adapts, or the metabolism gets damaged, just shows that you don't know how to beat the game yet. The body responds to what you do just like a computer program, always. As in, if this, then that. There is no coaxing the body to do anything. There is only one way weight gain and weight loss works and all the endless diets that people have come up with are just incomplete and incorrect variations of this one way. I'd be more than happy to explain the rest of it if you give me an email address. You could always just pick up my quick diet guide on Amazon, too. Thank you Doctor. - Tom

From medical point or maybe biochemistry point, wen there is no glycogen something called glyconeogenesis happens that's when fat components, glycerol which is a component of triglycerides in adipose tissue converts to source of energy, protein source does that too alanine, ( an amino acid ) and other aminoacids. and I will like to believe that you know that amino acids make up protein and protein makes up myoglobin, troponin which are components of muscle, so when there is no glycogen, fat will be source of energy next and then comes proteins which means eating into gains. And starvation mode from same view and my own thoughts our body uses macros for a big amount of processes in our body and our body always works in favor of protecting it self. Starvation mode is when the body senses that food isn't coming in as it used to so in defense of next absence of food it will store the fat for energy source for other procedures that occurs in the body. that is why some people recommend eating consistently in small portions and yes to be honest it only makes much sense and trueness on a molecular and cellular level so I guess scientifically it does not make much sense. I like this video its so educational.

I'm having sort of interesting results myself. Got an injury and stopped training when I had 70kg, which I did acquire for a very short time. I came from 60kg more or less. After a while completely untrained I've returned to my old 60kg, and after restart training, I did noticed a increase in hungry, not the graving type per say, it feels like an optimal demand from my body to increase my food intake in order to growth (I assume my strength training also plays a role. I still maintained the exactly same diet plan (mostly low carb, with a few smothers with high IG carb, I also tried a keto diet for a few weeks, the first days I felt no hungry, but the following days I got the very opposite effect, specially in the morning. What is more interesting is. Since I'm following a bulk, I am being more active when idle and more prone to waste and spend energy. It feels like my body keeps asking me to keep doing exercises whanever I can. So for one side, my body asks me to acquire more energy. But for the other side, it also asks me to burn more energy. Kinda odd.

Jeff. Bro. Fantastic. Smashes the like button multiple times The reduction in volume well into a deficit makes a lot of sense, to me. I began monthly 36 hour prolonged fasts a couple months ago, and attempted a back/bi workout twice. I lost muscle mass and strength only in the muscles I worked during the fast. Significantly. And in a fast, your muscle glycogen is definitely depleted. Then, gluconeogenesis, with fats to glucose, takes time, and it's namely used for steady-state glucose release, not immediate access; so, it's a lot easier to just burn muscle proteins for energy during the workout. That was what it seemed, to me. My muscles burned themselves to produce the necessary energy to complete the hard, hard workout. The workout was also torturous. 0 energy. Naturally, I don't workout while fasted, anymore. The keto claim is that over time, your body will adapt to gluconeogenesis to fuel workouts. But, don't really want to burn my muscle in the meantime. Anyway, very, very interesting video. Quality content, Jeff.

Hi Jeff I love your content I have a request for you to do a video on imbalances. I have some imbalances in my hips and shoulders. It may just be how my skeleton has positioned itself over time but I was wanting your opinion on this. One of my hips is higher than the other and the opposite shoulder is higher than the other. So Im slightly crooked, its not noticeable to anyone but me. I have went to the chiropractor and she did do a X-ray of my skeleton which I could clearly see my spine curved ( I dont have scoliosis) But I eventually quit going because it didnt seem to help. Theres not pain when I workout. Actually I used to have pain but it seems like now that I workout regularly I havent had any pain. But when I watch myself squat I can see my hips going more to the left. And if I do any pressing movements my right hand will press further. I was just wondering if there was anything I could do in the gym to help correct this? Thanks for your time Jeff Keep up the good work

Man. After 4 years of working out everyday and dieting I went from 155 - 210 and when we would slash my calories every time I wouldnt respond to the point where I was accused of not eating properly or sticking to the deficit. I was so frustrated I left my trainer and turned to chemicals which ended my body building. I mean. That whole journey started with the want for a 6 pack and nothing more which never did happen. I stopped for another 4 years. During the last 2 I ate awful but kept so much size. Ultimately gaining to 230lbs. Recently I started eating clean and working out again with the thoughts of this in my head. Hoping to take this knowledge and implement it long term on my own. Thanks for the great videos

It seems that this interview is firmly within the paradigm of the simple calorie deficit. Intermittent and/or extended fasting changes it all. Fasting is very lean-mass sparing specifically when compared to normal calorie restriction. Further, paradoxically, a multi-day fast often-times will INCREASE your resting metabolic rate due to an increase in production of adrenaline and noradrenaline as well as increasing growth hormone which aids with lean mass retention. There are many people who have dieted down conventionally through calorie restriction - reducing their resting metabolic rate - and then were forced to turn to fasting to repair (increase) their resting metabolism.

Jeff, dr Trexler, the Audience, please do help me. I have starved my organism, too much exercise - too little calories, probably anorexia or something like that. I lost my testosterone. Is it possible for me to get it back? I eat more and train less of course, but nothing has changed with my testosterone levels. I make injctions. Second thing. I have damaged my knees. Earlier, I could run like 15km, no problem. Having 'dieted' for 2 years, I cannot run longer than 1km before my knees hurt, making it impossible to continue. Can it be reveresed? I love running, it hurts me not to be able to do that. Is there a solution? If I eat more for example? I am like 8% BF right now.
