This Study Determined the #1 Diet to Drop Weight the Fastest (comparing diet types) 

Who knows where the internet/RU-vid is headed lol - my newsletter is a more lighthearted place to get content via email, but if you sign up Get a Free 1-Week Gut Health Protocol. No strings attached. Just good info: www.thomasdelauer.com/gut-health

Thomas, tomorrow marks one year since i started doing Keto. I've lost 200 pounds in this year. My doctor was worried about my heart, she sent me to the heart doc. Heart doctor was happy with the speed as the weight was worse for me than the loss.

I went strict keto omad and lost 140lbs in less than 6 months. Reincorporated carbs slowly after that and I worked out before so I had muscle memory and now I'm jacked after 1 1/2 years. 34" waist 6'2 210lbs now. At 60yo I'm cool with this 😎

Did Keto for ten years (keto snob) then switched to Mediterranean. Keto works but Mediterranean blows it out of the water in terms of effectiveness, sustainability, ease of diet, mood enhancement, ect.

Keto saved my life. I have now merged more with Mediterranean and I will eat this way for life!!! I do natural carbs and am beyond happy!!

I’ve never felt better after nearly a year into keto. The results are two numerous to recount here, but at nearly 70 years of age, my longevity journey accelerated on keto.

I started keto to help my ME/CFS which I developed after a throat virus in 2005 and, stupidly I was on a very low fat high carb diet - remember the high fibre diet people? Yes well, don't do that... 🙄 I struggled to stay in ketosis so ended up doing carnivore in January 2023. A year later I am virtually 95% recovered. I have no joint pains, my brain fog has gone and I have no fatigue. Even my prolapsed discs and long term tendonitis no longer cause issues - or at least there is no pain even if the discs and tendons might still be repairing. My first aim wasn't weight loss but I did lose 3 stone in a year and my physical strength and stamina improved during that time. I was pretty poorly with my ME?CFS. I was bedridden for quite a few years and housebound for longer. I'm not going to pretend , I miss a lot of foods but I missed my life more. The improvements to my health far outweigh the limited food choice. I am now able to be out with my horses and ride again. At my worst, a good day was being able to go outside for a bit of a cuddle and maybe brush a mane for a short time before returning to bed to sleep. Do I fall off the carnivore wagon - yes sometimes. I'm human and to deny myself any treat EVER isn't sustainable. But most days I have beef, pork, eggs, some cheese and coffee with double cream. I sometimes have some berries wwith some double cream. I know some carnivores couldn't manage the dairy so at least I can do that. I also recognise that many would find my diet far too restrictive, and honestly if it's just about keeping weight under control then a more relaxed long term WOE is better than loading up on high carb/processed diets. We have to experiment and find our own sweet spot. (NB I did get alarming heart rate symptoms when I first started carnivore but quickly sorted with electrolytes.)

Lift weights, build muscle, increase your metabolism and protect your body. Eat enough protein, eat whole foods, cut back on refined sugars, artificial sweeteners & bad oils. I did keto & lost weight. Loving low carb, high protein, it's so much more sustainable and freeing.

Wow great video thank you Thomas

Carnivore and 72 to 96 hour water fasts. The autophagy from the long term fasts will prevent loose skin. The longer you can fast the more autophagy ❤❤

You’re a wonderful teacher may I add that I believe the best way to eat is the Tao way which is where you combined meats and veggies or carbs and veggies I lost a lot of weight and more importantly what you have to take care of is your metabolism rate. In the early 80s I was on the keto diet and I lost weight so fast that my metabolism slowed down and even though I was a very thin person I was in New York modeling and had to be extra thin what I didn’t count on, the diet doing was ruining my metabolism because after I lost 15 pounds, of course most of it came back quickly because my metabolism slowed down and then after that, it took me years to finally get my metabolism, running well, which is the answer to all diets, all losing weight and all health, you need to eat stuff and get it through your body quicklywhatever you don’t use for energy instead of letting it stay in your colon as toxins or in your body as fat. Please check out the diets very easy to stay on your whole life and your whole body not some freaky thing where you can’t have all the fruits and vegetables you want that’s just crazy that makes no sense because the healthiest food on the planet out of the color of the rainbow and you need to eat them abundantly every day day.

Being 4'10, my calories can't pretty much go over 1400 calories unless I workout every day. I tried 1500 and gained 30 pounds. I wish someone would make videos for shorter people.

It's intriguing to note that the protein proportion advice presented here diverges from the insights shared by other protein authorities such as Don Layman ( ru-vid.comUgkxSM-q5Yuep7TQHptmNF9456kUKqQkhjf7 ). Considering one's age, there seems to be a call for a higher protein intake, a sentiment echoed by Layman. It's like a daily fixed requirement where the only 'macro dials' at our disposal to tweak are the levels of fats and carbohydrates. Quite the nutritional puzzle!

Loved this video! Thanks for the great content and also keeping an open mind!

Thomas, thank you for always being honest and sharing all new knowledge with us. I am thankful for your ever-growing knowledge.

Good stuff. I like the chill delivery, and the honesty about your experiences and about the solutions that have worked for you and others. I also dig the "main idea" delivery, the friendliness to being in the proper zone, moving in the proper direction. That's awesome, because we're all rather variable, so we have trouble sticking to absolute directives regarding... most things in life.

Great info! Just started on this and feel so much better on Keto!

HYLETE! dope repping that brand. Good to see them coming back!

grapefruit and chocolate raspberry LMNT sooooo delicious and it does help me feel good

Tom. Thank you for helping me get on keto almost 2 years ago. 60 lbs lighter now, almost at my college bodybuilding weight, and I'm 61yrs old. I did give up on you a year ago as you seemed to contradict your own videos very frequently. All of us in this space are definitely growing in application and fine-tuning our WOE. I'm carnivore now which is even easier to follow, mostly red meat. But I've subscribed again as many of your recent videos are lining up with current nutritional science, aka protein and exercise, so good on you. Overall we're all on our own path to health. But this video especially makes alot of sense, the importance of getting rid of our metabolically diseased fat as fast as possible then find a WOE that is sustainable for you. I thank you for that, Great stuff keep up the good work!! 🥩🧈🥓🍳✌️👍

For myself, I am one of those people who love the foods needed for a keto diet and I find it very easy to do intermittent fasting with those foods. But every now and then I do miss eating real pizza, ice cream, and especially some pasta dishes such as chicken Alfredo. So I just take a break for maybe a week or two and just go back to keto very easily because I start getting sick of junk food and start craving meat and eggs again. I don't go out very much, but when I do, I just eat like everyone else at the party. Of course, I gain a few pounds, but now that I've been on keto for a few years, I know exactly what to do and can shed those pounds quickly. I think this is the only way to make keto sustainable in the long term. Otherwise, if you are feeling deprived all the time, it definitely is not sustainable. No truer words have been said that if your eating habits feel like a diet instead of a lifestyle choice, you won't be able to lose weight and keep it off.

Keto has helped me. At 65 I feel great and I have been keto for 6.5 years

I use my drinks for appetite control and energy and electrolytes that work in tandem with those

Love this thanks Thomas

Mr Thomas, let me start by saying thank you, I have been on this ball we call earth for 64.5 years and I've been watching you for a relatively long time, that being said, you hit it on the button with this RU-vid episode. Don't let it go to your head, but your on the right track due to your relentless digging into the data and truth,, a little like me. Keep on keeping on.

One thing I noticed when I went full keto for 8 months with no break, I focused the foods on keto, but I also made sure to use organic plant-based supplements (multi vitamin/mineral/phytonutrient, etc.) to fill the nutrition gaps and it worked great. It was worth the extra price to get better supplements over the cheap stuff and the bloodwork for physicals I got during that time was awesome. I also back to my college athletics weight, which was a nice despite it still falling short of my college athletics physique.

I find from the keto forums that many people migrate from keto to a low carb or Mediterranean diet over a few months

Great Video Thomas! Thanks again for the no BS approach

I truly appreciate your channel, and I like that you don't censor negative comments and engage in a mature and respectful manner with those who made the negative comments. Thank you for sharing your knowledge with us . I appreciate and look forward to each video.

I lost 130 doing keto, I hit a plateu because I did do much protein. Doing carnivore now, it works better for me. Slower progress but lost 5lbs last month.

That’s how I felt on keto, I kinda lost interest and didn’t lose much weight due to almond flour and keto snacks. Now that I’m on carnivore diet, it feels much more sustainable and I’m enjoying the weight lose and the feeling of not needing to eat all the time.

The best diet I ever did and lost 60lbs in 55 days was intermittent fasting. Hands down. Felt the best too plus it was easy

I watch your channel from time to time. I appreciate your approach. Never pushy. But I am so confused with all of this. Carnivore, Keto, low carb, Mediterranean, etc. So I’m older. And I’ve decided clean eating is the best thing for me with a few other things added in occasionally. Otherwise, I’ll give up. At my age, ya sometimes figure yourself out. But cheers to those who lose weight any safe way they can. I applaud you all🎉 But I also appreciate that you’re open minded. Thx for the video.

Thank you Thomas, this was a great video !

Preserving your muscle is also paramount. Keep that growth signal stimulated.

I think its time to say that personalized diets are ideal over trend types diets due to the broad spectrum of dietary needs and variety of health conditions.

Keto didn’t agree with me, but I think I did too many nuts. I had sharp pains under my left rib cage and that was the end of keto for me. I think too much fat negatively impacted my gallbladder. I am exploring metabolism confusion, low carb some days but still get protein, just not adding fats.

I love that you always are open to changing things up according to the latest data. That is science. Thank you for always being a wonderful source for the current everchanging knowledge.❤

Great video. I went a little more hard core than Keto for the past 5 weeks. I went Carnivore and slashed 16.7 lbs. I am 6'2 and now at 207.6; which for my size isn't bad. The goal is to trim off about 3-5 more lbs and then focus on low carb/keto and only do the carbs on quality food.. For example, an amazing pizza once in a while vs just an OK pizza. Less weight means longer distance running, longer time on the road and mountain bikes too without needing a break. Keep up the great work! Love the videos and the science you back it with!

One of your most insightful vids. Thanks.

I did the same, lost 60kg in one year with keto, singen Oktober including carbs for increasing streanth... you helped me so much for this jurney

The ApoE4 diet which is a Mediterranean ketogenic diet was unsustainable for me because it was very restrictive. This was what I could and could not eat. Fruits ❌️ Grains ❌️ Beans ❌️ Potatoes ❌️ Nuts and seeds ❌️ Coconuts ❌️ Animal fat ❌️ Egg yolks ❌️ Dairy fat ❌️ Vegetables ✅️ Avocados ✅️ Olives ✅️ Macadamia nuts ✅️ Lean meat ✅️ Fish ✅️ Egg whites ✅️ Low fat dairy ✅️

Relieved to hear you say this. I lost 20 kilos in 6 months doing Keto, felt great, but I couldn’t sustain it. I’ve gained the weight back and gearing myself up to lose it yet again. I love fruit and vegetables, maybe Mediterranean is the way to go for me this time.

Veryyy good video!! Thank you!

Please discuss carnivore eating in comparison

I got lean (~12% BF) with Keto. I ramped up protein even more and I'm getting even leaner. Thanks for explaining the studies and looking at both short and long term ways of staying healthy!

I agree with losing faster.. I've heard some doctros refer to losing fast on weight loss surgery food plans, with the same analysis. I remember a candy bar diet to lose fast. Doctors said it didn't matter what you ate, as long as you stuck to it and Lost the weight . Get healthy quicker and then manage what your intake will be. jo

Keto, or Adkins induction phase worked like a miracle for me Lost 10 lbs of water the first week and 20lbs of fat over the next couple of months , went from 200 to 170 and maintained for about a year just eating responsibly. In the last year though I've crept up to 200lbs again 😢 Got to do induction again.

Agreed! 🙌

I know some people may feel you’re a “traitor” to the keto community… but I personally love that you’re always growing and learning and teaching us new things when new science comes out. It’s important to keep up with new science. Otherwise we will never reach that optimal state we’re all trying to achieve. I appreciate all your hard work over the years. Thank you.

It's good to write in comments what actually helped us in real life. I am in my late 40. Since 2017 I am in keto direction. I am for sure not too strict (Ups and downs but I need just to keep my weight plus improve muscle mass!) but this great feeling when my body produces ketones is UNDENIABLE. I love it! ❤

Metabolic switching by fat burning system and sugar burning system. If we metabolic switch we can do both diets and feel amazing w tonnes of weight loss🥳

Keto here, love it, I OMAD every other-day , take a fasting salt daily, very active . What a great life I have, no health issues.

The only issue with undulating between Ketosis and Mediterranean is building up insulin insensitivity during higher bouts of carbohydrate intake. I think the remedy for this is based on the greater fatty acid profile while observing ketosis. I also feel that doing in frequent one to two time per month watered fast, but also feel good. Cheat days are important as well. As long as there is a list that adhere to healthy cheats ahead of time. Getting away from bolstering one’s health is never a treat.

ketogenic diets are not based on calories, they are based on reducing/eliminating carbs

I want some wine & Prosecco!!

Please do a video on what food your low carb/Mediterranean diet consists of these days.

What Thomas goes on to talk about further in this video is of even greater value for Type 2 Diabetics who wish to remain in remission for life after embracing a Low Carb Lifestyle (and Type 1 who wish to eliminate the debilitating highs and lows in blood glucose and reduce injected insulin by 50%). The only proven way to sustainably keep blood glucose and insulin in the non-diabetic range is to become Fat/Keto Adapted to avoid constant eating and be able to do Intermittent fasting to reduce visceral fat and avoid cyclic weight gain that puts it back. To sustain this for life while enjoying meals and being able to occasionally eat higher carbs at social gatherings (without being kicked out of being Fat Adapted) requires becoming Metabolically Flexible which can be achieved with a "Modified Mediterranean Keto Diet". The next important fact to know is that as one adopts this particular diet for life, after a few years or less, Blood Ketones drop to 0.1mmol/l in the non-fasted state which may concern many and lead them to unhealthy ways to raise ketones again which is totally unnecessary. Prof Tim Noakes explains this phenomenon in a Q&A session shown in ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-psqBPrwicQE.html

Why so few people % give you a thumbs up for that? I am with you for a few years already and learned so much from you. I also like that you are not praying the same every time. Keep it up bro!

Almost no weight loss on keto. I was frustrated, tired, hangry ( yes I was mineralized, not cheating and had sufficient protein and fat). Ended with sibo. Twice a 9 months increment for 9 pounds lost and my cholesterol through the roof. I still believe it’s a great diet for most people. Rapid weight loss for myself, nope.

Keto-Teranian? So maybe more variety but with mostly the low carb options?

7:19 love LMNT!

Hi, what would be the ideal amount of protein a woman should get each day?

Hello Mr, Thomas, from Africa, keto is the best, once you reach your ideal weight, eat small amounts of fruits like knives, it's been 15 years in keto, I m very healthy and happy,

…as for quick weight loss, I went keto and fasted to beat diabetes and clean my liver ASAP. Now I'm low-carb, high-protein, and I'm most concerned with adding/keeping lean mass.

Keto diet is better for people who don’t exert much energy during exercise or any at all

Intermittent fasting with exercise 🤔

It is important to distinguish between fat loss and water loss, when looking at the scale. Ketogenic diets induce very quick results, initially, because they have a diuretic effect - meaning that it purges a lot of water - that other diets do not have. So a lot of the initial phase of weight loss, on low carb diets, is from water more than it is from fat. Where I think ketogenic diets are more effective, is that they make calorie control easier, because they are, in the long run, far more satiating. I think what would be more interesting is if a DEXA scan were done to see which diet actually produces the quickest fat loss as opposed to weight loss.

l don't eat the same as I did 2 years ago when I dropped 100 lbs with KETO, but I still keep my NET carbs under 50. Fiber! :) Haven't had a problem and I have flexibility in what I eat. My diet has set my epi clock back 30 years it feels like. I'm 68 and in the best health of my life. PROTEIN! DOUBLE THE RECOMMENDED ALLOWANCE! Anyway,,,

Bulking season. I’ll watch this in summer.

Does anyone know how much meat you should eat at least on carnivore? I am 6.07 feet, 27 years old and eat 3 eggs, 50g cheese and 200g beef a day, is that enough?

How long does it take to restore your metabolism after big weight loss? How long after a 7 day fast?

I’m super stoked about this click bait 😂information. I’ve been binge watching your videos on fat loss. The struggle is real and we need your continued research 🧐 ❤❤❤❤

I really miss loaded oats with yummy stuff on it, nuts raisins apples brown sugar raw cream . I grew up on them! But I found a great substitute Hemp hearts

My fastest weight loss occurred on the Paleo Intermittent Fast; not related to the Paleo Diet. A 12-hour FEED window, followed by a 36-hour water/coffee/tea with Stevia FAST. I had to set an alarm reminding myself when it was time to eat as I no longer spend every day planning my next meal. I tried to eat clean, most of the time, but didn't count calories. My energy levels stayed the same after a very quick adaptation. I started dropping a pant-size every 2 weeks. There were no problems with loose skin due to autophagy. My doctors intervened because I am on daily medications required to be taken with food.

Thanks

Fastest weight loss diets: #1 HCG #2 water fast #3 lion diet with IF #4 carnivore with IF #5 keto with IF (the closer to carnivore the better). This study just compared two diets. I have not done HCG in years and do not plan to again, but I lost 26 lbs. in less than a week on it. It was ridiculous. Whatever diet you are on, increase your fasting periods to increase your weight loss rate.

Hey Thomas, love the video. Curious if they measured muscle? As muscle is taking on more and more importance, Is it better to lose fat and muscle quickly or is it better to lose fat while preserving muscle? OR is it better to lose the weight faster and rebuild the muscle after someone has achieved their goal weight? Thanks, again.

What is the best proteins source for vegans please?

Love your channel. Ended 2023 Fasting, rowing machine 2x a week. Started 2024 with a bad shoulder, had to halt rowing. Still Fasting, but now i have covid. I listen to a ton of podcasts and i get confused on the path i want to stay.on. then i listen to you and i get my head back on straight. Yes at times you have a lot of content but i like that, you teach us what's out there. You are my Teacher Sir and I learn from your knowledge. You keep me focused and i appreciate that. XOXO. Any tips on getting over this Covid crap quickly?😅

So the 3 week diet/2 week maintenance rotation doesn't help mitigate the metabolic rate decrease?

Have you thought about doing a study of how diets affect men and women differently? Men were hunter and gatherers and women mainly picked berries and made bread. Did you know some women lose their period when they don't eat carbs?

I feld awful on Keto after 5 months.. sure, i lost tons of fat and in a very fast time, but for me it is not sustainable even with so called cheat days... and on top of that i had electrolyte issues aswell after this time...

I would like see you have Dr Andreas Eenfeldt on to talk about his new approach

For LMNT I like watermelon the most. I did not lie the chocolate melody combos and am struggling with finishing those.

This is great information on Diet strategy for Old Jocks like me--just love it, very practical consideration of what is involved in actually doing it {on rigid keto now, 12 Lbs down in 3 weeks, another 20 to drop into target range but I know I can't keep it up long term} Thanks for the great content.....Craig

pretty much feel like i do similar. i started out near keto, i know i couldnt fully commit to it but just even being mindfull of how many calories and carbs and fats you intake helps a great deal and can plan meals around them. ill still use keto labeled products too cause some are just good. when i can have 2 packs of high protein oatmeal, 2 pieces of keto jelly toast with high fiber jelly, and a greek yogurrt with my coffee i feel like i just ate a 3 course meal but it was only near 600cal and 41+g of protein. i know it should be pretty obvious knowledge by now but also with a good diet you need to exercise and it dont need to be anything rigorous or stressfull, if you can get out for an hour and just do some fast walking that goes a long way to helping you stay in shape and keeping weight off.

It seems to me that the more sedentary and overweight society gets, the more beneficial ketogenic diets become. At a healthy weight and activity level however, there are much more well-rounded diets that fit all kinds of preferences. So ketogenic diets maybe should remain an intervention rather than a convention.

Keto-ish plus cardio is the ONLY way I've been able to lose weight and keep it off. But I have to almost totally eliminate sugar and anything sweet tasting (including substitutes). The sweet taste cranks up my craving for sugar to 11. The only thing that has caused me to gain part of the weight back has been injuries that prevented me from doing enough cardio.

Carnivore would be at least as good if not better In my experience, I wasn’t fat particularly but lost stomach fat easily and no hunger. Eat one meal a day and as much as you want , insulin and electrolytes problems gone . Micro nutrients? Not a problem.

Hello! You did not mention that you eat beans on your Mediterranean diet. The foods you mentioned that you are now eating is basically still keto... except the fruit maybe?

The study ultimately did not find what is claimed. The ketogenic diet had an extremely high deficit of about 1400 kcal for men and 1200 kcal for women, while the Mediterranean diet had only a 500 kcal deficit. Naturally, weight loss depends on the deficit, known to be approximately linear. The ketogenic diet resulted in a body fat loss of ~15 ppb per day per kcal deficit for men, and the Mediterranean diet ~22 ppb per day per kcal deficit, which is much more. For women: Mediterranean ~18 ppb per day per kcal deficit and Keto: 15 ppb per day per kcal deficit.

Fasting and Keto to your goal, Mediterranean for maintenance.

@thomasdelauer Please define Keto. Like 70% fat? Or just simply low carb?

Disclaimer for all girls - you shouldn't be losing too much weight too fast while doing HIIT, you could lose your period and therefore health because of the huge cortisol release during too big of a calorie deficit and jumping straight into strenuous exercise. Guys don't have to worry about it, but we girlies do. Even if you're overweight, you can still lose your period.

Thomas I NEED your knowledge of protien. There are others like Dr.Berg who has said that too much protein will cause you to look older. Your thought on that ? Can you do a video on whether or not high protein causes you to look old/older. ?

Keto was such a struggle for me ! And I didn’t get leaner

Dry fasting with sauna sessions

11:21 : do you need to lose weight first before ramping metabolism through protein intake? Why not do it when starting to lose weight?

Thoughts from anyone? I’m on medication that can raise my cholesterol and it has slowly been going up. To avoid taking a statin, I’m trying to change my diet and exercise more. My nutritionist says to eat lean meat(including eggs) but I’m worried about my cholesterol going up.
