I’m super excited because in this video we will be talking about ranking popular Diet and Fitness Trends 2021. This is my opinion as a weight loss coach (so this video will also be full of weight loss tips) but I’d encourage you to create a diet plan rank for yourself, but your decision of what diet to do should be up to you.

A calorie deficit is required for weight loss but there are tons of different ways to accomplish that. Some people do intermittent fasting, water fasting, intuitive eating, clean eating, flexible dieting, counting calories, vegetarian diet, IIFYM, keto diet (ketogenic diet), or carnivore diet. Some popular exercise strategies are things like a HIIT workout, fasted cardio, yoga (we’ll talk about yoga benefits), or weightlifting, which is my favorite by way.

Spoiler alert (and you may already know this if you’ve watched enough Frumpyfit content) but mindful eating and calorie counting are my top two recommendations and I’ll explain why in this video.

In 2021 weight loss will hopefully be focused more on the individual and the science. We’ll see!

    Keto allowed me to lose 60 lbs in 3 months. This video is a joke you have no clue what you’re talking about. Maybe you needed the money from your sponsor, they use refined sugars after all 🙂

  2. Kelly Shannon on April 21, 2021 at 4:57 pm

    Where would you put Paleo?

  3. Sarah Carina Heri on April 21, 2021 at 4:58 pm

    so, I think I agreed with most of the classifications with you, however, I just want to point something out about YOGA!

    YOGA has a religious background! like – I know the western society has appropriated it for weight loss and just to stay fit and flexible and stuff, but the origin of YOGA is something the percentage of population that is part of Hinduism, and Buddhism considers sacred practice.
    As a Christian I am sometimes very upset about all the political structures around f.e. marriage, since marriage is something sacred between my husband, God and me. I rather had everything political just stay political (like – just change the official term on it, already, and everybody can have what they want, I don’t care, but something like ‘gay marriage’ doesn’t make sense to me, since ‘marriage’ FOR ME is something that includes a sacred, religious ritual, you know what I mean?).
    So I sometimes wonder whether people from a Hindi or Buddism background are upset about the Western world abusing their sacred practice that is yoga for something mundane like weight loss? I would NEVER do yoga because I would just deem it disrespectful (and of course because I am a Christian, and therefore I see spiritual conflict of interests in me, doing yoga LOL)

    Omg! I can’t watch you anymore! There is a benefit to fasted cardio and fat burn. Do your research. Don’t just spew your opinion and try to say it is facts!

  5. XC Sio on April 21, 2021 at 5:00 pm

    Some dieteticians say that if you dont eat 3 meals a day your body starts clinging to fat because it thinks hard times are coming? Is it true? I don’t want to eat if I’m not hungry and also I like fasting for 1 day after I ate too much… it makes me feel better

  6. jamie5mauser on April 21, 2021 at 5:06 pm

    Basically the concept is that fruits and vegetables would not be naturally available to us year round. So it’s thought to be a natural human diet that our species adapted to.
    The other point of carnivore is for autoimmune conditions, most substances that trigger autoimmunity are found in legumes, and basically any seed because the seed is the most protected part of the plant. Grains are a seed, nuts are seeds, etc.

    Carnivore is evolutionarily more natural and more healthy than vegan, if one had to choose one extreme over the other.
    It’s -30 here, good luck finding an edible plant let alone get all your nutrition through only plants. Animal nutrients are far more bioavailable to us than plant nutrients too so with eating animal foods only will provide all your necessary nutrition vs vegans who have to supplement and ship foods from all over the world
    Just food for thought 🤗

    And most ppl who do iifym do eat whole minimally processed food. It just means you can choose potatoes vs rice vs fruit for your carb. Whole eggs vs nuts vs fattier meat for their fat. But you can have a piece of chocolate if you choose or some ice cream even if you want, so you doing deprive yourself and binge. It’s more flexible than strict meal plans

    Walking is the bomb. I love it, it’s super easy and low effort. Each day I burn 200-400 calories through it. Today is unusually low (144) because I have been super busy.

  8. stargazerbird on April 21, 2021 at 5:08 pm

    Awesome content. A word of advice for reaching high subscriber numbers – slow down and relax and limit the vocal fry. You might have to edit more to cut the time down but the result would be so much better.

  9. Mary Blue on April 21, 2021 at 5:09 pm

    Thank you for thinking about the environment.❣️

  10. Sarah Gabrielle on April 21, 2021 at 5:09 pm

    What about if you are insulin resistant? Keto seems like my only choice. On top of that I have hypothyroidism.

  11. pratima talwar on April 21, 2021 at 5:10 pm

    It’s the yoga for me!

  12. Brooke Smith on April 21, 2021 at 5:10 pm

    Intermittent Fasting isn’t a diet!!! Stop it!! It is a timed window of eating. You should know this and know not to call it a diet!

  13. The CastFam on April 21, 2021 at 5:12 pm

    I just cant get enough of your videos 🥰 lol

  14. Angel Smoke on April 21, 2021 at 5:12 pm

    Is there a built link for a shop in Europe? Ps love your channel!

  15. Octaviah Gaming on April 21, 2021 at 5:12 pm

    It’s rough to see Keto dismissed so hard when it works for so many people, including myself. IF and Keto make me feel the best I ever have. I understand your points, but I would have certainly not put it in the ‘absolutely not’, personally.

  16. Stephanie Salvador on April 21, 2021 at 5:14 pm

    You should do a ranking of what you think best ever since routines are for building muscle!

  17. Eliana on April 21, 2021 at 5:15 pm

    I love that Hyram was born in Arizona, currently lives in Hawai’i and you were born in Hawai’i and live in Arizona. And then there’s me born and raised in Hawai’i 🤙🏼
    What a cool coincidence lol great video FrumpyFit 💕🌺

  18. Straw Berry on April 21, 2021 at 5:16 pm

    12.34…. I am so sorry but I just can’t stop laughing!!!! I am just eating my pickel…. cries …. hahaaaaaaahahhah

  19. Lena Leeper on April 21, 2021 at 5:17 pm

    @ hyram

  20. Maenad on April 21, 2021 at 5:18 pm

    I’m so glad you put clean eating in “you do you” what I like about it is because it’s adaptable (ie; it can vary from person to person). It forces you think hard.

  21. alexandre bernier on April 21, 2021 at 5:19 pm

    Hello. This vid is so instructive! I’ve been trying to find for a YouTube video similar to yours that explains the topics in this video. 🥼Your vid is similar to the content from this smart medical student Dr. Ethan! Doctor Ethan’s demonstrations are for sure knowledgable and I actually learned a lot for wellness. He is the most informative Dr in the UK and he explains diseases.

    You should see his YT out and give the medical student a like! 👉 #DrEthanNews

  22. limes4ever on April 21, 2021 at 5:19 pm

    Could you do a ranking of fitness add-ons like pre-workout, resistance bands, protein shakes, ankle weights and the like?

  23. V King on April 21, 2021 at 5:20 pm

    Intuitive Eating for overrated *shocked*

    I actually agree. Fitness influencers who say day of intuitive eating have always rubbed me the wrong way. I think the practice is for people who are already at a healthy weight but need to relearn a relationship with food apart from diet culture.

  24. AkaraTopaz on April 21, 2021 at 5:22 pm

    So glad you put walking into grossly underrated because I’m just at the beginning of my weight loss journey and it’s the only thing I feel comfortable doing and I enjoy it.
    Also working on turning that walking into hiking 😊

  25. Jennifer Hughes on April 21, 2021 at 5:24 pm

    Can you do a video on walking? Maybe discuss how many steps the average person should do daily

  26. Michelle Lauer on April 21, 2021 at 5:26 pm

    i’d love to see you compare popular diets: atkins, noom, ww, and others like that.

  27. Mary Magnan on April 21, 2021 at 5:30 pm

    I am a 66-year-old female I walk every day and do water aerobics twice a week for exercise but what other weight bearing exercises should I be doing to build muscle

  28. Maddie The Wrestler on April 21, 2021 at 5:30 pm

    I know it’s older but can you review gabbie hanna’s diet video? I would like to know your view on her approach.

  29. Peter Guilherme on April 21, 2021 at 5:30 pm

    "back when I was in college like in *cringe* 2015. God I feel so old."

    Me who graduated college in 2014

  30. sera on April 21, 2021 at 5:32 pm

    I loved this video! I found it very informative, and as someone with an eating disordered past I found it so helpful in the sense that it helped me to look at the way I eat and exercise from a more rational viewpoint. I feel like when I do allow myself to eat what I want and be mindful my body does balance itself out and I don’t have cravings or binge and feel satisfied. But when I see things on social media about how this and this diet is the best and optimal for health and weight loss I feel like I have to change everything and give up things I love in order to look a certain way. Personally I love breakfast and carbs and fruits and I know from experience that even if I have whatever I want, as long as I practice moderation I can maintain and even lose weight. I may not be super shredded, but that’s not for me either. But if it is, of course more power to you!
    I also agree yoga is underrated in terms of being a workout. It’s all about the style you choose! I have done some yoga that I am drenched in sweat and beat red doing them. It can be a very good full body workout and you don’t even notice the time going by

  31. Lucy on April 21, 2021 at 5:34 pm

    I also go to a butcher. Not only is it better for you, it seems better for the animals. Since they’re not separated and shoved into a slaughter home

  32. Melissa DiBacco on April 21, 2021 at 5:34 pm

    I like that you talked about Keto as not being a magical cure-all. I did Keto and while I did lose about 60 lbs it was not sustainable for me. I ended up gaining it back PLUS some. Now my ex-bf started doing it a year ago and it has done a lot of good medically for him as he had diabetes that they couldn’t really get under control. So for him, it really helped with regulating his numbers.

    This time around I am taking a different approach to losing weight. I am not cutting out food groups like carbs or even sugar but I am making better, healthier choices. I don’t think of food in terms of good or bad like I may have in the past. I have cut out pasta but that isn’t because of it being a "bad" food it’s more about how eating pasta makes me feel (super sluggish, bloated, etc). It’s also about serving sizes and learning portion control. I am tracking calories but not necessarily to make sure I don’t "over eat" but actually to make sure I am not falling into too low of a caloric deficit. Interestingly enough, when I eat 3 balanced healthy meals and 2 snacks a day, occasionally I struggle to get 1400 calories in a day and at my current weight that is pretty low. The weight loss is slow, but it’s sustainable and I don’t feel deprived or like i’m on a "diet". Next step is to add some cardio and resistance training 🙂

  33. Angel Smoke on April 21, 2021 at 5:34 pm

    Probably my favourite of all the videos you’ve made. Gave me so many answers but the best info was that I shouldn’t underestimate walking. I’m eating on a deficit and not loosing, yet in the summer I was able to because I went on walks and now I’m sure that is the difference. I’m doing yoga and resistance bands the past month, but you just confirmed that I need to insist on walking daily again, or at least 4 times per week. .? See I wasn’t sure if I had better results then because I started off with going down and up the hill I live on and it’s so Damn steep, I was hitting 150 bpm at times ! It was hard ,so then I just went downhill and had someone pick me up lol 😛

  34. Emily Goodwin on April 21, 2021 at 5:36 pm

    I’ve never seen someone with such similar views on weight loss as me I’m spooked

  35. beth hilton on April 21, 2021 at 5:38 pm

    I’m an ethical vegan for 7 years and cringe when I see someones gone vegan for weight loss

  36. Prodigal Daughter on April 21, 2021 at 5:39 pm

    Keto: absolutely not LOL ❤️❤️❤️😂🤣
    IF is my lifestyle that works best for my schedule. It isn’t for everyone. For me I like that my body is focusing on immune system rather than digestion. I haven’t been sick (knock on wood) in a very long time. Been over a year.

  37. hllyhtch on April 21, 2021 at 5:41 pm

    Hi Frumpy Fit! May you do a video on how to correctly go about weight training? Thanks!

  38. Karlee Tobin on April 21, 2021 at 5:41 pm

    I’ve lost 80lbs with keto in 8 months and have literally never felt restricted, my skin has never been more clear, my mental illness almost completely disappeared after struggling for 12 years with it. Its definitely hard and people definitely do it wrong which isn’t great but I really suggest you read some pro-keto studies. Eg: with keto BMR isnt reduced to the same level as it is with regular large weight loss so that big change in BMR that is expected (a la the biggest loser) isn’t seen in the same way.

    I totally see that it’s a restrictive diet, but if it’s done well it doesn’t have to feel restrictive (I ate pizza and ice cream last weekend for Valentine’s Day celebration) and also I feel fully satisfied just eating meat and veggies twice a day!

  39. pinkmeetsred on April 21, 2021 at 5:41 pm

    I was wondering if fasted cardio makes you burn muscle not fat. Is that true or just bs . I’m just curious 🥰

  40. Nicola on April 21, 2021 at 5:42 pm

    Ahh man eating that pickle was such a mood XD

  41. HolidayAdventures on April 21, 2021 at 5:43 pm

    I eat vegan 🙂 it has been 7 years now at the start of my journey I ate really unhealthy as a vegan. Now I have educated myself I eat alot more healthier. I went vegan to improve my health that is the only reason. I was 222 pounds February 2020 I am now down -67 pounds. I eat in a calorie deficit I dont eat vegan because I want to lose weight I eat vegan because of the way it makes me feel. I have so much more energy!=D

    Also wish the built bars had a vegan option!

  42. Nerdy Vegan on April 21, 2021 at 5:44 pm

    Love the vid but the “sustainably sourced meat” there is no such thing. No such this as “testing an animal well” when you kill them artificially impregnate, etc. So they are just using marketing tactics to make more money. I suggest using plant based alternatives when u would’ve eaten meat but I like getting protein from other places. Just consider, that’s all I ask 😇🙏

  43. My_Butt on April 21, 2021 at 5:46 pm

    I have pretty much zero clue of anything she said in this video because my little OCD eyes just kept staring at the beautiful organization of the books in the background thinking, “that is so pleasing….i wish there wasn’t a gap in the books on the bottom shelf.”

  44. JDTW on April 21, 2021 at 5:46 pm

    This video will not age well , not to be rude but you are for sure misinformed and uneducated on certain aspects. Although there is a lot of good information, fasting should be encouraged as it’s natural for humans to do so and extremely healthy. Food has not always been readily available and we are made to fast and to not be digesting food throughout the day and every day. The fact that people will turn to "binge" eating is not because fasting is not a good method but because many of our foods have been engineered to be highly addictive. Keto is not a diet , its a more natural and wholesome way of eating, it encourages eating whole foods that are not heavily processed as many foods that would break Keto are often unhealthy. Anyways i can go on forever but for anyone reading , make sure to do your research!

  45. Lorraine B on April 21, 2021 at 5:49 pm

    There was a year where I first got my fitbit and I worked at a chill office job where I would take longer walking breaks. I was constantly walking and getting my steps in before I knew it I lost a significant amount of weight. I was meal prepping and on the weekends didn’t really watch what I ate but man looking back I lost like 50 pounds without even thinking much about it. I did go to the gym as well probably did my spin classes 3x a week and lifted 2x a week. I will say I think the walking was the secret weapon tho!!

  46. Carmen Curvaceous on April 21, 2021 at 5:50 pm

    I am starting the 16:8 intermittent fasting for my insulin resistance (with supervision from my doctor), but we’re also doing so with caution to make sure I don’t slip into unhealthy disordered eating or trying to extend my fast. Can be helpful but agree to be careful and not for weight loss!

  47. Theresa m on April 21, 2021 at 5:52 pm

    I exercise fasted because of ibs. Once I eat sth. I bloat like crazy and that makes me so lethargic that I simply can’t workout as well anymore 🙂

  48. Marcella on April 21, 2021 at 5:54 pm

    I think most people misunderstand intuitive eating. BTW I wouldn’t necessarily call myself an intuitive eater simply because it is not something I have been actively implementing, but from what I have gathered from others on it, everything you put in the mindful eating category is actually part of intuitive eating. I think in essence most people would agree with the principles of intuitive eating but somehow it got a bad rep as just eating whatever you want, which isn’t the full scope of intuitive eating. This btw is not meant as an attack on you. The video was a lot of fun. Just something I noticed a lot online.

    I would actually black out when doing cardio after not eating. I tried running in the morning one time and I threw up a little…
