00:00hi i'm lisa valenti registered dietitian with healthline and today we'll be talking about
00:04the ketogenic diet otherwise known as the keto diet super popular diet but what is it what kind
00:11of foods can you eat is it good for you what are the downsides of trying keto plus we'll give you
00:16some meal ideas and hopefully help you decide if trying the keto diet is right for you
00:30what is the keto diet it's a high fat moderate protein ultra low carbohydrate diet so very
00:37different than the way that most people eat the ketogenic diet is set up so that about 70 percent
00:42of your calories come from fat about 20 percent from protein and no more than 10 percent of your
00:48calories are coming from carbohydrates the idea behind the keto diet is that it puts your body
00:53into ketosis normally our bodies run mostly on carbs we break down the carbohydrates we eat
00:59into smaller molecules into simple sugars called glucose and then we're able to absorb that and use
01:05that as energy when there's no carbohydrates left we can tap into the small amount of carb sources we
01:12have in our muscle but most of our energy stored as fat in the body or if we're not eating any carbs
01:17we can get that energy from fat in our diet so what types of foods can you eat on a ketogenic diet
01:26well pretty much anything as long as it doesn't contain carbs so think about foods like meat red meat pork
01:34chicken bacon and sausage you can eat nuts and seeds you can eat low carb vegetables so think about
01:41spinach asparagus and again some of those moderate carbohydrate containing veggies like onions and
01:47peppers may also have a place in your diet because it's not zero carbs it's just low carbs so some
01:53fruits you may find on a ketogenic diet like berries tend to be lower in carbohydrates than fruits like
01:58mango pineapple and bananas you can also include lots of different oils and fats in your diet so avocado
02:05oil olive oil butter coconut oil those can all be part of your diet so when it comes to the list of foods
02:11you can't eat you may think that feels a little bit longer when you decide to start a keto diet
02:15because some of your favorite foods like pasta rice brownies ice cream so anything that's super starchy
02:22anything that's really sweet might not be allowed on keto diet because of the carb intake or the carb count
02:28on those foods those are some foods you can eat on the keto diet but how might it come together at meal time
02:34now it helps if you know how to cook and you have a little bit of creativity but some breakfast ideas
02:42on a ketogenic diet might be a cheesy omelet so you're having eggs cheese and you add some of those
02:48non-starchy vegetables in maybe asparagus or a little bit of peppers a lot of people doing keto may also
02:54stray from traditional breakfast foods and have some other meats or avocado for breakfast so again instead
03:00of putting avocado on toast you might use avocado as a topper for an omelet or an egg muffin so that
03:06you're keeping that fat high and those carbs low some lunch and dinner ideas for the ketogenic diet
03:11might be putting together things like chicken salad or a shrimp salad making them with the full fat
03:17versions of mayonnaise or greek yogurt serving them with a side of greens dressed with olive oil you can
03:24get creative with different stir fries again using low carbohydrate sauces to put together
03:29meals and instead of serving your meals with rice or over noodles you can make zucchini noodles
03:35or try cauliflower rice so with a little bit of creativity you can still have a diet that has
03:40a lot of different varied fat sources vegetable sources again trying some of those things for
03:46snacks that may be lower in carbs like berries paired with something higher in fat like a full
03:51fat greek yogurt and then again sometimes just grabbing a handful of nuts or something like that
03:56which are higher in fat do have a little bit of carbs but not a lot also the keto diet may seem
04:01really appealing because technically you could eat all the bacon and sausage and cheeseburgers
04:07without buns that you want and still maintain your fat and carb ratios you could do that but then
04:13you'd be getting a lot of processed meat in your diet which isn't linked with great health outcomes so
04:17to truly get the benefits you're going to want to focus on eating things like sardines and salmon and
04:22avocado and nuts and less of the ultra processed foods let's talk benefits of following a ketogenic diet
04:32most people who follow a keto diet will lose weight while you get to eat all those high fat foods
04:38you're probably ending up consuming fewer calories than you were on whatever way of eating you were
04:43before you went keto that's because it's really hard to overeat high fat foods they're very satisfying
04:48very filling and so you tend to have smaller portion sizes and a lot of those easy to grab
04:54snack foods like potato chips pretzels popcorn those won't fit on your diet so weight loss tends
04:59to be at least a short-term benefit for people following a ketogenic diet the keto diet may also
05:04be easier to follow than some more complicated diets once you have an awareness of how many carbs are
05:10in a food you have a good sense of whether or not you can eat it and you don't necessarily need to
05:15be counting calories or tracking any of your intake as long as you stick to choosing those high fat and
05:21lower carbohydrate foods more often low carb diets in general have been popular for a long time so
05:27there's typically something for you to work with there but it does require some cooking skills some
05:31basic nutrition knowledge what's really interesting about the ketogenic diet is beyond weight loss its
05:37effect on certain chronic conditions so the diet actually came into existence in the 1920s as a way to
05:44help kids who have epilepsy stop their seizures so there is some promising research around following
05:50a keto diet and reducing your risk or helping manage symptoms for certain neurological conditions
05:55like alzheimer's ms and parkinson's the research is really preliminary because it wasn't until recently
06:01that more people were trying keto and more researchers were looking into its effects but we do know that
06:06it changes the way that your brain gets fuel and there may be some benefits to following a ketogenic diet
06:12for those neurological conditions that said we really need to do more research to learn more
06:17and when it comes to chronic conditions and a keto diet it's not all good news
06:24a recent study found that eating a keto diet or a very low carb diet may increase your risk of heart
06:30disease and again i think it comes down to which type of foods you are choosing to include on your keto diet
06:35is it olive oil and almonds and salmon or is it bacon and sausage and processed cheese and again
06:42they both can fit but which are you choosing more often plus all of our individual disease risks vary
06:47so someone who has heart disease in their family or is maybe less active might be at higher risk to
06:52begin with so talk to your doctor as you're thinking through if the ketogenic diet is right for you
06:57another downside to following the ketogenic diet is that as some people enter ketosis they experience what's
07:03called the keto flu now that's exactly what it sounds like you're truly experiencing flu-like symptoms
07:09because of your dietary changes that may be headaches nausea fatigue diarrhea constipation you just don't
07:16feel great and now one way to help reduce those risks of keto flu is to make sure you're really dialing in
07:23your water and electrolyte balance as you start ketosis you're cutting out a lot of foods that are rich
07:29in electrolytes like potassium and magnesium and sodium so you may want to consider being mindful
07:35of your intake again making sure you're getting enough of those non-starchy vegetables like celery
07:40has potassium in it but so do bananas and potatoes which you're not really going to be eating so really
07:45being mindful of which foods contain those micronutrients potentially adding an electrolyte
07:50supplement to your water and making sure you're staying hydrated to help reduce those symptoms
07:55anecdotally some people say that just going low carb before they enter ketosis can help them
08:01because they're not going from eating a lot of carbs straight to an ultra low carb diet so you may
08:06want to consider sort of weaning yourself into keto by just focusing on cutting back on carbs and then
08:12deciding to make the leap all the way into a keto diet a ketogenic diet also may not be for everybody
08:20if you're pregnant or nursing it's not recommended to start a ketogenic diet also if you have a history
08:26of eating disorders or disordered eating because the keto diet is very restrictive it is likely not
08:32right for you if you're at higher risk of certain chronic conditions like heart disease you also may
08:37want to talk to your doctor so you have a better sense of what embarking on the keto diet may do to
08:42your health so talk to a doctor or a dietitian who knows you and your health concerns and issues more
08:49closely it also may be helpful for people with diabetes but it's not the only way to manage your
08:54diabetes so if you do have diabetes and you're interested in this but you really love carbs just
08:59know that you don't have to cut them out to manage your diabetes there's lots of different ways to eat
09:04and you can certainly still have carbohydrate containing foods and manage your blood sugar if
09:08you're doing it in a smart way and choosing more of those good for you carbohydrates more complex carbs
09:13that have fiber so those starchy vegetables those fruits and whole grains as with any
09:18diet it's really important when you're especially when you're cutting out food groups to be mindful
09:23of the foods you are choosing you really want to have nutrient-rich options more often when we look
09:29at the research overall if you're just doing keto to help lose weight what the research shows is that
09:34the best diet to lose weight is the one that you can stick to long term so if cutting out all carbs
09:40forever doesn't sound great to you you may want to consider changing the way you eat and focusing just on
09:46adding more fruits and vegetables or adding more fiber to your diet or lean protein in order to
09:50help you meet those weight loss goals without necessarily entering into ketosis i hope you found
09:55this video really helpful if you do decide to try the keto diet we have lots of resources on healthline.com
10:01and again i highly recommend that you read up and learn a lot about nutrition because if you're gonna
10:06do keto the right way you kind of have to become a little bit of a nutritionist yourself let us know what
