Hi Gigi, Low carb and keto is about the balance of macronutrients eaten (fat, protein and carbs), not specifically meat or lack thereof. Most people on keto do eat meat, though some people do vegetarian keto. Fat is actually necessary for many body processes. There is no issue for the kidneys with a high fat diet, but if you eat too much protein that isn’t great for the kidneys. It’s a common misconception that keto is high protein (it isn’t). Keto is great for diabetics as it naturally helps stabilize insulin. All of this being said, please know I’m not a doctor and you should consult your doctor on any medical questions or before starting any diet. If you have more questions that aren’t medical questions, I recommend our low carb & keto support group here.
One downside to a ketogenic diet for weight loss is the difficulty maintaining it. “Studies show that weight loss results from being on a low-carb diet for more than 12 months tend to be the same as being on a normal, healthy diet,” says Mattinson. While you may be eating more satiating fats (like peanut butter, regular butter, or avocado), you’re also way more limited in what’s allowed on the diet, which can make everyday situations, like eating dinner with family or going out with friends, far more difficult. Because people often find it tough to sustain, it’s easy to rely on it as a short-term diet rather than a long-term lifestyle.
However, ALSO be aware that most doctors get very little training on nutrition and don't understand the general effect of foods on the body. They are also taught that ketosis is dangerous, and so they know even less about ketogenic diets. Hence, if you ask your physician about this diet, you may get push back and a scary "ketosis-is-dangerous" sermon.
For a snack that needs zero preparation, reach for the olive jar, Griffin suggests. Olives are mostly made up of fat, specifically healthy monounsaturated fat, Berkley Wellness points out. Plus, as research published in the Journal of Agricultural and Food Chemistry notes, they're loaded with antioxidants, and are low in calories and carbs. Keep in mind that olives can contain a lot of sodium, though — sometimes as much as 42 milligrams in one olive, according to Berkley Wellness.
For most people, this eating style is a significant departure from the diet that they are comfortable eating. Most of us build meals around lean protein and carbohydrates, not fat. So before you decide to adopt the diet, it's smart to evaluate keto meals plans and think about whether or not you think you can stick to it for the long term. For example, if you are an eater who loves to include plenty of fresh fruits and vegetables at every meal, you might not be able to maintain this eating style.
But the real reason why keto plans fail most of us is that they're not sustainable for the long term. Holidays, vacations, work functions … there's likely at least one scenario in which you'll find yourself eating higher-carb foods. And the same reasons why we see immediate weight loss on carb-restricted diets is the same reason why we see immediate weight gain after adding a seemingly harmless sandwich back into the mix: The water weight comes back instantly with glycogen storage.
Since this is my full-time job, donations really help me keep afloat and allow me to post as much to the website as I do. I really appreciate any donation you want to give, but you can change the price yourself. I’ve added in $15 as the suggested price. I think that’s a very fair price considering other websites are charging in the hundreds of dollars, and I’ve seen what they are like on the inside.
No fruit but some berries. Apples have too many carbs. Pineapples will create massive insulin spikes. Never consume fruit juices: Valuable phytonutrients are bound to the fiber, and these are lost; plus the juice is cooked, removing many other nutrients. You’re basically just drinking concentrated fructose. You can get away with one-half to one cup of berries a day.
"My suggestion is to start with changing your mindset first and foremost around three very important facts: this is not just another diet, you don’t have to live in Ketosis forever, and you will not be depriving yourself. Having said that, if you are used to eating highly-processed sugary food and refined carbohydrates you’ll need to ease into it," she explains.
You’re transitioning. Your body is equipped to process a high intake of carbs and a lower intake of fat. Your body needs to create enzymes to be able to do this. In the transitional period, the brain may run low on energy which can lead to grogginess, nausea, and headaches. If you’re having a large problem with this, you can choose to reduce carb intake gradually.
