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!

    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!

  2. Lisa Hannah on July 31, 2021 at 9:42 pm

    You might want to try a treadmill desk, do your work and walk.

  3. Kelly Shannon on July 31, 2021 at 9:43 pm

    Where would you put Paleo?

  4. Melina Lol on July 31, 2021 at 9:44 pm

    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…

  5. Sarah Gabrielle on July 31, 2021 at 9:46 pm

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

  6. AkaraTopaz on July 31, 2021 at 9:50 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 😊

  7. Brooke Smith on July 31, 2021 at 9:50 pm

    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!

    Thank you so much for your positive outlook on veganism! I love to see people in the fitness community supporting veganism.

  10. Melissa DiBacco on July 31, 2021 at 9:55 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 🙂

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

  14. Jennifer Hughes on July 31, 2021 at 10:01 pm

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

  15. jamie5mauser on July 31, 2021 at 10:01 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

    Any idea what lipstick she’s wearing or ones of similar shades? It’s soooo pretty!

  18. XC Sio on July 31, 2021 at 10:09 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

  19. NIxi on July 31, 2021 at 10:09 pm

    Ahh man eating that pickle was such a mood XD

  20. Prodigal Daughter on July 31, 2021 at 10:10 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.

  21. Betty Stroh on July 31, 2021 at 10:14 pm

    Can you talk about Whole Foods plant based diets as opposed to vegan?

  22. Lorraine B on July 31, 2021 at 10:15 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!!

  23. Marcella on July 31, 2021 at 10:16 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.

  24. Taylor A on July 31, 2021 at 10:17 pm

    Hiram is actually not very qualified to speak on skincare and he has sold out over the past year so I wouldn’t really compare yourself to him. Don’t sell yourself short.

  25. HolidayAdventures on July 31, 2021 at 10:17 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!

  26. Straw Berry on July 31, 2021 at 10:17 pm

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

  27. Theresa m on July 31, 2021 at 10:18 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 🙂

  28. The CastFam on July 31, 2021 at 10:18 pm

    I just cant get enough of your videos 🥰 lol

  29. Krullerized on July 31, 2021 at 10:18 pm

    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 🙂

  30. Lisa Hannah on July 31, 2021 at 10:20 pm

    I looked up what intuitive eating is, and it sounds extremely similar to Naturally Slim, which is what I’m doing. And it’s the absolute easiest and most effective weight loss I’ve ever done. And it’s incredibly easy to see myself eating this way for the rest of my life. It teaches me to trust myself and not obsess over food. Look at Naturally Slim, it’s excellent. It’s not exercise, so I’m looking for tips there, but I think maybe you’re under rating it, at least for some people.

  31. Angel Smoke on July 31, 2021 at 10:20 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 😛

  32. Brooke Smith on July 31, 2021 at 10:20 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!

  33. Sarah Heri on July 31, 2021 at 10:21 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)

  34. Aysha V.A on July 31, 2021 at 10:22 pm

    thank you so much for the content you put out! It’s so informative and answers so many of the doubts I’ve always had. Also, I think dancing/zumba in general is v underrated as a form of cardio. I’ve seen gym bros completely disregard it or shit on it but damn I get winded after a 1 hour session even though I used to do 20 min HIIT sessions 2x a week 🥵. And it feels so good even though I’m quite terrible at dancing.

  35. stargazerbird on July 31, 2021 at 10:23 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.

  36. Cold Leif Arts on July 31, 2021 at 10:23 pm

    Could you do a video on weight loss apps? I am currently using Noom, but after watching your videos I am not sure if they should have me on a 1200 calorie diet or not. :/

  37. Karlee Tobin on July 31, 2021 at 10:23 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!

  38. Michelle Lauer on July 31, 2021 at 10:24 pm

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

  39. beth hilton on July 31, 2021 at 10:26 pm

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

  40. Lucy on July 31, 2021 at 10:27 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

  41. Nerdy Vegan on July 31, 2021 at 10:30 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 😇🙏

  42. Mary Blue on July 31, 2021 at 10:31 pm

    Thank you for thinking about the environment.❣️

  43. Caroline M. on July 31, 2021 at 10:32 pm

    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.

  44. My_Butt on July 31, 2021 at 10:33 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.”

  45. Angel Smoke on July 31, 2021 at 10:34 pm

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

  46. V King on July 31, 2021 at 10:35 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.

  47. pratima talwar on July 31, 2021 at 10:35 pm

    It’s the yoga for me!

  48. Taylor Mandeville on July 31, 2021 at 10:35 pm

    I’m normally a silent watcher on YouTube but I have to like and comment your videos. Your channel is my greatest 2021 discovery. Your opinions are obviously educated but you have the ability to vulgarize them so that we, the general population, can have a better understanding of health and weight loss. I love how you don’t mindlessly polarize information like the fitness industry does. You’re very rational and get straight to the tea and that’s very useful. Thank you for making these videos, you’re a very smart and beautiful woman 🙂

  49. Maenad on July 31, 2021 at 10:36 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.

  50. Stephanie Salvador on July 31, 2021 at 10:39 pm

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