Is Intermittent Fasting On A High Carb Diet Bad?


The Ripped Dude Program

Intermittent fasting is blowing up. However, there’s been some controversy lately over whether you can do intermittent fasting and eat a lot of carbohydrates. It’s well established now that carbs don’t make you fat and it’s mainly about caloric intake. But, there are some concerns about high carb intake, ketosis, appetite regulation, irritability and muscle loss. In today’s video I explain whether you can fast and follow a high carb diet effectively.



  1. Why are people always on one extreme or the other? High carb or low carb then demonizing the other.

    Why can't we eat a moderate carb, fat and protein diet,

    I am a woman trying to lose weight on a 2 meal a day 1200 to 1400 calorie diet using IF eating 100 ro 125grams of carb.

    I can't go either way it affects me badly in different ways
    If I do:
    Low carb I can't sleep;5
    High carb inflammation increase exponentially.

  2. Yes the body can run off glucose but glucose is not the ideal fuel you fool. Excess glucose ferments which cause disease, fool. Cancer, diabetes….
    Fats do NOT ferment n are therefore a better fuel, provided they're natural fats NOT man made like margarine etc.
    Seems the body can tolerate more carbs when doing IF and if doing OMAD seems the body can really do well on high carbs, low protein (maybe 30grams). I'm a carboholic n can still lose weight when doing IF.

  3. You guys love the keto high and drool over autophagy but think you must intermittently fast to get the benefits of autophagy. Wrongo bro scientist. Autophagy is all about protein. When you are eating high protein your body does not engage in autophagy because it is not triggered due to over use if protein. Our bodies naturally recycle many of our amino acids from our bodies through autophagy. Its going on all the time and doesnt reqire ketosis or intermittent fasting. Only when you overload the body with overt protein does the body stop autophagy. So being a low carb high protein cultist actually hinders your natural autophagic response. This is why a natural low protein high carb diet made up of whole foods is the best natural autopagic diet. Its why whole food vegans kill cancer naturally without having to do all this stupid shit and shows that paleo and keto are actually eating disorders. GO WHOLE FOODS HIGH CARB AND ENJOY LIFE, EAT AS MUCH AS YOU WANT AND AUTOPHAG day and night …naturally. dummy!

  4. I eat a cup of rice, a sweet potato, a half a can of beans, and a bunch of veggies and nuts for my omad each day. Fasting until the meal is incredibly easy for me, The hardest part is fasting after the meal and I find as long as I include a bunch of fiber I dont have cravings afterward, just as he said. Good work Phillip.

  5. I’m a high carb vegan and I fast for 22 hour daily bases. I’m fine with it but I hear you follow high fat diet. How do you follow high fat on vegan diet? Do you eat a lot of nuts and seeds? What do you eat on daily bases? Thanks.

  6. lots of respect to you for being honest and neutral over Carbs,there are people who follow keto diet and in their view carbs are like a demon and on the other side the people eats lots of carbs (like Asians) and still manage and healthy weight.I and following OMAD plan and don't worry much about carbs and I'm still loosing my extra weight

  7. If I eat in 4 hour window
    30% carb 50%fat 20% protein ( slow carb )( the carbohydrates will be come from fruit ,vegetables and oats no white rice no white bread nothing junk or processor)
    And I will be not in the ketosis
    Did I will lose weight ?

  8. New here. Thanks for this. Do you have recs for carb cycling? I find going either keto or high carb alone are both not sustainable. Also, are you saying that you can get into ketosis even when doing OMAD high carb? That part really confuses me. Thanks!!!

  9. Ya I'm vegan and intermittent fasting. Eatting low carb and high fat would annoy me. There are a lot more option went eatting carbs than with eatting fat.
    All I'd be able to eat is avocados and nuts with veg. Not a lot of options.

  10. If you do the one meal per day diet and eat carbs so you do not go into ketosis, isn't that the same like a calorie reduction diet that will eventually lead to metabolism decrease?

  11. In my experience high carb diet works well with IF but it's easier to sustain with short feeding window (2-4h), consisting of 1-2 big satisfying meals which are high volume and have low/medium glycemic index.

  12. Carbs by themselves are not inharently bad for you or fattening. Its when we pair high fat with the carbs does it make the food fattening because our bodies first primary fuel source is glucose (carbs, sugars). And when fat is paired with high carb meals your body is going to use the carbs and sugars as energy first and then store the fat as excess energy. So when these two macros are mixed it has a greater chance of making you store fat. So really these should be eaten alone and not paired together.. witch tends to cause inflamation anyway and you know how bad that is. I just eat a high carb plant based diet. feel good and I like the fact I am not supporting physical and emotional abuse to animals that just want to live their lives.. Factory farming is also probably destroying our planet 🙁

  13. It depends on your genetics . Some peole naturally do btter better on a low carb and some of a high carb . I've lost weight on a high carb low-fat diet. You just hve to try both, your body will tell you which is best, by how you are feeling and wheter you have lost weight.

  14. I have been eating high carb with intermittent fasting, and I've lost around 30 pounds. I'm also in my early 50's and going through hormonal changes. It is working for me and has been one of the easiest ways I've ever lost weight! High carb, IF….the way to go for me!!!!

  15. Carbs aren't fattening but insulin is and its the bodys natural response to carbs. Also when most people eat carbs they mix it with fats and insulin teh storing hormone it is stores fats away while it uses glucose for immediate energy.
    Cholesterole is important for testosterone production and not carbs.
    Fasting wont put you in ketosis in under 24hrs in reality it takes more like 3 days if your healthy. Depending on insulin resistance you could not enter ketosis through fasting alone it takes excersise as well and forcing the body to use fats by consuming high amounts of it.

  16. I eat 2-3 meals after 16 hour fasts everyday and thats worked roid like awesome. Ripped and do half the work i used to do. Im the kind of person who can eat pounds and not gain weight though so maybe thats why 3 meals is okay for me. I still eat clean but i can eat anything i want.

  17. "Treat your body like a science experiment." Yes, this may sound awful to some people, but it totally makes sense to me. There are many variations between what some people will thrive in and what others will struggle with. You do need to check yourself and importantly be patient to push through some initial struggles (don't give up easily). Your body adapts, so take it slow. It is normal for your body to reject a new eating pattern. It takes a few days. I lost 35lbs (16kg) of weight I carried most of my adult life (age 29 to 49) over 6 months of an IF regimine and have been able to keep it off easily. I am in my early 50's and I have arrived back at my college weight, mentally sharp and I don't have to follow a strict diet (keto or low carb). I listen to my body. For me, some days are OMAD, some days are 18/6, and some days are 20/4. My meals consist of heavy vegetable/salads (60% of what I eat), Protein 25%, healthy starches 15%. I feel great, fit my clothes wonderfully and don't have to stress over what I eat (like my parents do following a strict keto diet). Some days I eat a much heavier carb diet (have to get some Italian pasta occasionally). I love that I can get more accomplished every day without stressing over meals or meal planning, etc. If I have a business lunch, I do 18/6, if I have a really busy day, I do 20/4. Totally fits my lifestyle. So glad to have researched this, wish smart guys like Philip had been around 25 years ago. 🙂 . Philip, thanks for the balanced approach.

  18. So if i workout 1st thing in the morning and then fast for the rest of the day i may be able to be fat adapted. I am doing 16/8 IF and eat carbs with lot of fiber so i dont elivate blood sugar. My questio is am i using fatty acids for my muscle and liver to produce ketones or am i just using fat to produce glucose trough gluconeogenesis. I am training fasted and eating like this for mounths. If someone can make this easier for me to understand that would be great. Thanks
