Being insulin resistant, I’m always interested in fasting as a way to shed a few pounds. But I’m also curious how much calories a person on a full keto diet would eat. So I’ve been researching how many calories a keto person is allowed to eat, and how much weight they will lose on a fast.

What do you do when you’re not fasting? For most people, the answer is to eat. But why? Is it because we’re weak-willed? Or maybe we’re lazy? Or maybe we’re just not smart enough to know how much to eat?

When one thinks about fasting, one thinks of the religious, the spiritual and the health enthusiasts. There is no doubt that fasting has health benefits, but it also means the removal of food from the body. This makes it very important to know how many calories one will actually eat when fasting and when one is not fasting.. Read more about how many calories on keto diet and let us know what you think.

Fasting is a common practice in the ketogenic community. By restricting your calories for a specified period of time, you can burn fat and become healthier and fitter. However, not everyone has the luxury to be able to skip meals or fast for several days a week, and some people simply find it easier to avoid eating for a few hours a day if they know they won’t be hungry.

Visiting a website about weight loss can be confusing at times. There are so many different diets, meal plans and the truth is that most do not work. Keto is one of the few that do work. All you have to do is follow the keto diet for at least two weeks and you will see that you have lost a lot of pounds.

 

Is there any research on individuals who take antipsychotics and eat an LCHF diet? What can I do to prevent a cortisol spike waking me up at 3 a.m.? And how many calories do individuals on the keto diet eat while they fast?

Get the answers to these questions and more in my Q&A this week:

The metabolic syndrome and antipsychotics

Weight and metabolic characteristics are essential concerns while using antipsychotics, since I work as a psychiatrist. Hunger is generally the most serious issue. Is there any research on this population using the LCHF diet? Do you believe this will help to alleviate the alleged hunger?

Eric

Good day, Eric!

There haven’t been any research on this, as far as I’m aware. My personal hypothesis is that medications that operate as dopamine antagonists (such as antipsychotics) decrease food pleasure and cause individuals to eat more in order to get the same level of satisfaction.

In principle, a low-carb diet may assist to alleviate this issue, at least in part, since a low-carb diet reduces appetite.

Best wishes, Andreas

I’ve been on a keto diet for a few months now and I wake up at 3am every morning with a cortisol surge. Are there strategies for eating before bed to delay normal hormone development until 5am or later?

I believe the dawn phenomena begins around 3 a.m., but since I’m a light sleeper, I wake up fully at 3 a.m., am awake, and am unable to go back asleep. I don’t have diabetes. Is there anything I can add to my ketogenic diet before night to help slow down the cortisol surge so I can sleep until 5 a.m. or later?

Jeffrey,

Adding a little quantity of carbohydrate (for example, 20 grams) in the evening may assist, but it also decreases the ketogenic diet’s impact.

Best wishes, Andreas

How many calories do individuals on the keto diet eat per day or per week?

Although it is common knowledge that calories should be counted, this is not the case. This is something I’m aware of, and I use MyFitnessPal to calculate and monitor my macros (which aren’t technically calories, but they’re still there). However, I’ve hit a snag and have been bouncing back and forth between dropping 80-85 pounds (I still need to lose 70-100 pounds). On weekdays, I fast 16-17 hours and eat 2-3 meals a day with my family on weekends. I get it: eat when you’re hungry and avoid eating when you’re not.

Can you tell me how many calories a person on a 16-8 hour fasting diet eats in an LCHF (keto) body? When the calorie count is less than 1000, MyFitnessPal stops functioning. My buddy consumes less than 1000 calories each day. I typically consume between 1,000 and 1,500 calories each day. Could you perhaps provide me with a phone number so that I may further explain my expectations and understanding? What is the accepted norm? What does it mean to be healthy? How much do skinny individuals consume on a regular basis? How many calories do individuals on the keto diet eat per day or per week? After having struggled with my weight my whole life and hearing disinformation from experts, I believe calorie counting is the final bastion of ignorance. (No one should consume fewer than 1200 calories a day, and even that isn’t enough, etc.)

I’m in desperate need of a keto calorie range.

Thank you very much, Kelly.

Kelly,

I’m not sure whether that query (how many calories?) is the correct one. Typically, the response is: It varies, and it relies on what you’re attempting to do. If you are very overweight, your body may deplete these energy stores, leaving you with just the necessary nutrients (proteins, essential fatty acids, minerals, vitamins). As a result, I’d prioritize low-carb, nutrient-dense foods such as meat, eggs, and veggies. I’d put a lot less emphasis on calories since the less net energy you consume (mainly sugar and other carbohydrates), the simpler it is to shed those additional pounds.

However, I believe that 1,000-1,500 calories per day would be a decent starting point for you. That, in my opinion, is not the most essential goal to pursue.

Please read the following instructions: Should I keep track of my calories if I’m on a low-carb or keto diet?

Best wishes, Andreas

Fasting and the ketogenic diet

I’d want to know whether you can have a keto dessert after supper if you’re on a keto diet and fasting. And, because I’m allergic to dairy, and avocado seems to include a lot of dairy in most recipes, do you have any suggestions for food options for me?

Thank you so much, Marvelette.

Marvelett,

You can have dessert once in a while, but you’ll probably lose weight quicker if you don’t. Here are some dairy-free recipes for you to try.

Best wishes, Andreas

Ketogenic diets are a hot topic these days, with increasing numbers of people looking to lose weight, improve their health, or use it as a tool for athletic performance. The low-carb diet has been criticized as fad diet, with some even claiming that it is not effective for weight loss.  Ketogenic diets are meant to induce ketosis, which is a metabolic state where your carbohydrate stores are completely depleted, and your body relies on fat and protein for energy..
