It Can Complicate Eating Disorders
While omad keto or other methods are healthy when approached properly, they can cause complications for a person with a history of eating disorders.
For example, those who have experienced the negative effects of anorexia and bulimia may fall back into their problematic eating behaviors when trying out keto intermittent fasting.
Even worse, it may cause some people to develop disorders they didnt have before trying out keto intermittent fasting.
Make sure to try this approach only if you have a positive body image and are comfortable with the way you look.
Otherwise, it is possible for somebody to get obsessed with their diet and suffer from emotional problems.
Potential Benefits Of Omad
There isnt much science on OMAD. Most researchers have looked at other forms of intermittent fasting.
In animal and human studies, various forms of intermittent fasting have been linked to:
- Weight loss
- Improved body composition
- Better insulin sensitivity / blood sugar regulation
- Improved heart disease risk factors
- Lower inflammation
- A healthy gut microbiome
Some of these benefits may be driven by circadian rhythm enhancement. Your circadian rhythm is your 24-hour wake / sleep cycle, and it regulates a large chunk of your genome.
Most intermittent fasting protocols tend to favor daytime eating schedules. By not eating in the evening, you send the correct sleep signals to this clockand this influences everything from blood glucose levels to inflammation. Eating during the day also appears to promote a more anti-inflammatory gut microbiome, at least in animals.
But come on. Isnt there any data on OMAD? Actually, there is.
One small study published in the American Journal of Clinical Nutrition found that when normal weight people ate one meal a day , they had significant reductions in fat mass and cortisol, the stress hormone. During the 8 weeks of OMAD, however, the participants also had higher blood pressure and LDL cholesterol, both markers of increased heart disease risk.
Another small study used a similar setup. This time, normal weight men and women had higher fasting glucose levels on OMAD than when they ate three meals per day.
History Of The Keto Diet
The ketogenic diet has been around for decades, but has been surging in popularity.
Note that long-term, flexible dieting is just as good at helping your reach your weight loss and fitness goals as a keto diet.
It could be argued that flexible dieting is better as it is less restrictive and more sustainable.
However, a keto diet may be appropriate for someone looking for faster initial results¹.
- Those training for fitness competitions.
- Those trying to lose weight for an event but have a shorter time window.
- Those who have tried flexible dieting but because of metabolic issues are unable to lose weight eating normal levels of carbohydrates.

Ketogenic Diets And Weight Loss
Lets defy scientific practice for a minute and skip to the results section first. Ketogenic diets seem to be better for weight loss and weight loss maintenance in the long term.
In a meta-analysis of 13 diet studies, individuals who were assigned to a very-low carbohydrate ketogenic diet had significantly more body weight loss in the long term compared to conventional low-fat diets. Bueno2013
Another analysis, this one including 17 different randomized controlled trials, found evidence that diets with a low-carb intake were associated with significantly greater weight loss compared to low-fat diets. Sacknerbernstein2015
A one-year trial compared a diet that induced nutritional ketosis to a usual care intervention in type 2 diabetic patients. It demonstrated that the ketogenic diet intervention was better at reducing weight along with improving blood glucose control better than usual care. Hallberg2018
Where does the weight loss come from? Some claim that its all water weight, but this may only be true initially. In the long term, fat loss may be a substantial portion.
For instance, in one study, weight loss after 15 days on a ketogenic diet was due to total body water . After this time point, however, a slight recovery of body water was observed. Water loss may occur due to glycogen depletion. Glycogen is usually stored with water, and so a loss of glycogen means water will come along with it, along with some ketones and sodium. Gomezarbelaez2017
What Exactly Do The Results Mean
After you entered all of your data and calculated your macros, you will get results that look something like this:
Lets start with the calories. Simply put, a calorie is a basic unit of energy that helps us understand how much energy we can potentially get from the food we eat. Calorie intake is one of the most critical variables to be aware of when you are trying to change your body composition.
If you eat fewer calories than you need to maintain your weight then you will lose weight. Conversely, eating more calories than you need to maintain your weight will cause you to gain weight.
Notice that I am saying weight loss and weight gain rather than fat loss and gain. By manipulating your calorie consumption, you will predictably change the numbers on the scale, but whether or not those numbers reflect a strong bias toward fat loss depends on the other numbers from your keto macro calculator results.
Fat, muscle, and water can all be lost and gained during the course of your diet. The proportion of weight you lose as fat, muscle, and water depends heavily upon the macronutrient content of your diet . If youd like to learn more about the macronutrients, check out our guide to macros.
Protein is essential for maintaining and gaining muscle mass. Eating less protein than recommended by our keto calculator will typically cause you to lose more muscle mass while eating the right amount of protein will help you maintain or gain muscle mass .

You Like Endurance Training
Endurance training and keto are a perfect combination: they improve each other in a way that allows you to progress rapidly in both areas.
Ketogenic diets provide a great fuel source for endurance training.
Relying on carbs for energy is a struggle for endurance training since youre going to run out early into your training and performance will drop accordingly.
However, body-fat provides hundreds of thousands of calories of energy without the need to eat.
Once youre keto-adapted, you can make huge changes to your performance and when you start to experience extreme fatigue-related losses.
On the other hand, endurance training boosts ketogenic diet performance by rapidly accelerating your ability to oxidize fats.
This, in turn, boosts efficiency in burning fats as fuels and pushes you towards nutritional and exercise-induced ketosis, as well as faster keto-adaptation.
So, if youre looking to perform at your best in endurance training or you enjoy it more than heavy weights or intense gymnastics the ketogenic diet is going to be a great way to really open up that calorie deficit.
Customizing Your Keto Menu Calories
If youve found this meal plan but you need a higher calorie intake, here’s how to make this fit your calorie goals.
If you need extra food, all you need to do is multiple portions to match your calorie needs.
For example, if you need 1800 calories per day, youll need to increase portions by 33% or a factor of 1.33 .
Just multiply all ingredients by a factor of 1.33 and your set! If you consume a 2,000 calorie diet, then simply multiply by 1.66 .
Because some of the higher fat foods may contain a small amount of carbs, if you need to increase your fat intake, I suggest doing so by adding extra teaspoons of an unsaturated oil of your choice, or by adding any high fat sauce you’d like. Remember that oil is pure fat , but it is also a high-calorie food!

My Protein Is Higher Than My Fat Recommendation What Should I Do
You may notice that the percentage of grams of protein you have to eat is much higher and fat is a lot lower than the percentages that are typically recommended for keto. This can happen for two reasons:
The only problem that high protein intake can cause, however, is lower levels of ketone production. If this is the case for you and you want to maintain a higher level of ketosis, then try decreasing your protein intake to the lower end of the recommended range or restricting carbs a bit more.
Keto Macros For Athletes Explained
Many athletes are as serious about their diets as they are about their exercise regime. They have to be if they want to perform at their best. More and more athletes are giving the keto diet a try. Research has suggested that most athletes wont have a problem going keto, though it may not be the optimum diet for those doing endurance sports. Keto has become popular for good reasons and you may find its benefits suit you and your fitness goals.
Athletes who follow a more traditional diet use carbs as their primary energy source, but when your body is in ketosis the emphasis shifts to fats. The longer you have been on a keto diet the better you will be at using fat for energy. Dont be surprised if your performance dips at first when you change to a keto diet, as you have to give your body time to adapt. This could take up to 12 weeks, so dont dismiss keto as not for you too quickly. The better your body adapts to the keto diet the more it will use fat for fuel.
So, what are the potential benefits of changing to a low-carb keto diet for athletes?
Fat provides a more stable degree of energy than the more volatile glucose. This allows the ketogenic athlete to exercise for longer periods without the roller coaster of glucose-fueled energy levels, particularly during low and medium strength workouts.
Studies have suggested that a well thought out keto diet can encourage recovery from exercise which may be attributed to anti-inflammatory properties.

What Is The Recommended Keto Macros Ratio
We’ve already mentioned that the most common ratio for macronutrients during a ketogenic diet is 70% fats, 5% carbohydrates, and 25% protein. Some dietitians recommend increasing the proportion of fats even higher, to 75%, and cutting protein down to 20%. You can modify the macro split by manually inputting the desired percentage in our keto weight loss calculator.
You could also try an alternative to the standard ketogenic diet: a cyclical keto diet, favored by those trying to reduce their body fat and build their muscle mass. In this diet, you regulate your nutrition by adhering to the standard keto diet for 5-6 days in a row, followed by 1-2 days of increased carbs intake. The goal of such a diet is to regularly replenish the glucose reserve in your blood.
Targeted Ketogenic Diet And Carb Intake
If you engage in regular, intense physical activity, note that the above ratios might not cater to your performance needs. Thats where targeted ketogenic diets come into play.
In targeted keto and during training times only you might want to integrate a carb boost before and immediately following your training sessions. This will ensure your muscles have enough glycogen to perform their necessary tasks, both during competition and within in-season training.
When adopting this targeted principle, youll follow the above macro guidelines throughout the day. However, after you leave the gym , youll consume 15-30 grams of fast-acting carbohydrates. These should be consumed within a half hour after training ends.
Theoretically, your body uses these carbs immediately to repair and restore itself. Therefore, your ketogenic state wont be adversely affected.

What You Can’t Eat On The Keto Diet:
It’s a pretty exhaustive list, and probably includes some of your favorites: Bread, rice, pasta, fruit, corn, potatoes, beans, baked goods, sweets, juice, and beer all get the axe. Basically, you have to avoid most sugars and starches. Whole grains like oatmeal don’t even make the cut!
If you’re tempted to go keto, consult with your doctor before embarking on any extreme weight loss plan. While the ketogenic diet can include some healthful foods , many others get nixed .

How To Calculate Macros
The optimal amount of macros is different for each person, based on age, height, weight/body composition, activity level, body fat percentages , and weight goals.
How do you know what your optimal macros should be? The easiest way to determine the correct amounts is to use a macro calculator like the MyMojoMacros calculator. Just input the requested information and it will calculate the breakdown of proper calorie intake, protein, carbs, and fat needed for you to lose, gain, or maintain your weight, depending on the health goals you set.
Regardless of what number of calories are recommended, the general consensus within the keto community is that you want to keep your net carbs to 20 or less grams per day to lose weight, unless youre an active athlete, in which case you can up your net carbs a bit.
Note: Factors such as age, gender, family, and personal medical history, and genetics influence how your body responds to specific macronutrients and whether or not they help keep your body in ketosis. For this reason, we recommend you discuss your intended diet with a medical provider or registered dietitian who knows your health history, has an understanding of the ketogenic diet, and can help you make choices that are best for you around healthy eating, fat loss, meal plans, and low-carb diets.

Keto Macros For Weight Loss Explained
The keto diet has become extremely popular for weight management. Many people have achieved life-changing and even life-saving weight loss on keto, and hearing or reading about those positive experiences may be what led you here in the first place.
Keto macros work for weight loss by depriving the body of carbohydrates, and therefore glucose, the main fuel used for energy in all cells. Instead, the body turns to an alternative source ketones, which it makes from fat.
When carbohydrate intake is restricted, the body first uses the glucose stored in the liver and breaks down muscle to release more glucose. After just a few days, with no more glucose available, the amount of insulin in the blood diminishes and allows the stored fat to be used as an energy source, turned into ketones by the liver. This state is called ketosis.
So, by significantly reducing carbohydrates and inducing a state of ketosis the body actually burns the stored fat to produce energy while allowing enough protein to preserve muscle.
There are several theories that have been suggested why the keto diet is successful in leading to weight loss. These include:
The high-fat content decreases food cravings.
Restricting carbs leads to a decrease in appetite-stimulating hormones.
Converting fat to fuel requires more calories to be used.

Do You Have To Count Calories
Ketogenic diets generally don’t give rules for calories, although they might give suggestions. For example, the Atkins 20 Diet â one of the most well-known ketogenic diets â recommends that women aim for 1,500 to 1,800 calories a day, while men aim for 1,800 to 2,200. It also advises dieters to limit empty calories and to stick to a list of approved foods for each phase of the diet.
One good thing about a ketogenic diet, says Franziska Spritzler, RD, author of The Low-Carb Dietitian’s Guide to Health and Beauty, is that most people will naturally stay within this calorie range while on the plan. While it’s easy to fill up on empty carbs like crackers and cookies, she says, those foods are off limits on a keto diet. It’s more difficult to eat large portions of keto-approved foods that are higher in fat, protein and fiber.
“You’re going to be eating veggies, which are high in fiber and can fill you up on very few calories,” she says. “And you’re also going to be eating things like nuts and meat and cheese and oil â which, yes, are high in calories, but they’re also very satiating, so you really only have to eat small portions to get your fill.”
