What is the keto diet? How does it work? 

Hello everyone, I'm Nutrition Coach  Abhilasha. Today, I am talking about the keto diet,

How it works & what its cons & pros.

Recently, the term keto diet has been very popular among fitness freaks. They follow this diet to lose their extra weight in a very short period. It lowers blood sugar and insulin levels and shifts the body’s metabolism away from carbs and toward fat and ketones.

I'm here going to tell you about its function, facts, and pros and cons.

Keto-Diet-:

The ketogenic diet is a very low-carb, high-fat diet that shares many similarities with the Atkins and low-carb diets.

The keto diet drastically reduces carbohydrate intake and replaces it with fat. This reduction in carbs puts your body into a metabolic state called ketosis.

When this happens, your body becomes incredibly efficient at burning fat for energy. It also turns fat into ketones in the liver, which can supply energy for the brain.

A ketogenic diet (KD) is defined as a high-fat, low-carbohydrate diet, with adequate protein content, which makes the body utilize fat, rather than carbohydrate, as a preferred energy substrate. 

In a carbohydrate-replete person,

 this substrate is converted to glucose,

 which is used as a fuel by all 

organs, including the brain. In carbohydrate depletion, ketogenesis is activated in the liver, which breaks down fat into fatty acids and ketone bodies. 

   

These ketone bodies are able to cross the blood–brain barrier and provide energy to the brain. Ketones can also be utilized by other organ systems as an efficient energy source.

The term ‘ketogenic diet’ was first used by "Russel Wilder" in 1923 to describe a high-fat, low-carbohydrate diet that produced ketonemia.

Ketogenic diets can cause significant reductions in blood sugar and insulin levels. This, along with the increased ketones, has some health benefits.

Various forms of KD are now used in clinical practice. The amount of carbohydrates permitted varies from 20 to 50 g/day. This depends upon personal metabolic and weight loss goals, upon 

the planned duration of KD, and upon individual.

Different types of ketogenic diets

There are several versions of the ketogenic diet, including:

Standard ketogenic diet (SKD): 

This is a very low-carb, moderate-protein, and high-fat diet. It typically contains 70% fat, 20% protein, and only 10% carbs.

Cyclical ketogenic diet (CKD):-

This diet involves periods of higher carb refeeds, such as 5 ketogenic days followed by 2 high carb days.

Targeted ketogenic diet (TKD): 

This diet allows you to add carbs around workouts.

High protein ketogenic diet:-

This is a modified ketogenic diet that combines more protein, especially in the following form: the ratio is often 60% fat, 35% protein, or 5%carbs.

If only we could do a study on cyclical or targeted dieting in ketogenic diets. More advanced methods, such as these latter two cycling ketogenic diets, are not only an alternative for beginners, but they also come under the control of athletes and bodybuilders only.

Clinical Way of Keto-Diet:-

On the keto-Diet, description is of a gram of fat per pound of lean body fat. But energy intake is not free, and if people consume more than they burn, the body will convert surplus food into Melting away pounds always sounds too good to be true. Dieting can be a very anxious affair 

 Like everything else in life, it`ll require something of a sacrifice on your part. You will have to live off an apple for breakfast instead of jelly doughnuts and that sort of thing. There are several ways you can deal with your mother-in-law--one way is not to have her over for dinner. Maintenance of

Symptoms vanish without any News of such things, ie, weight loss away from symptoms tends to make the illness or condition less severe. Maintenance of a lowered body weight leads to compensatory changes in energy expenditure, which limit the potential for

Mechanism of food:-

Keto-Diet acts by inducing a state of physiological ketosis. 
This is achieved by consuming minimal 
carbohydrates, thus creating a state of carbohydrate starvation. As the carbohydrate substrate is minimized, the insulin requirement comes down. This leads to resolution of insulin resistance and reduction in insulin secretion, with a concomitant fall in glucagon production. Caloric and nutrient intake is maintained through fats and proteins.
Fats are preferentially utilized to produce energy for the body and are burned up.
Keto-Diet induced weight loss is accompanied by a mitigation in the increase of circulating ghrelin. This helps to avoid hunger and cravings and contributes to the maintenance of weight loss.

Pros and cons of the Ketogenic Diet-

Pros-

A form of lifestyle modification encourages self-discipline, self-care, and self-management, and prevents “medicalization” of lifestyle disorders.
Keto-Diet reduces the pharmaceutical burden and provides comprehensive metabolic control. Keto-Diet offers pleiotropic nonmetabolic benefits.

Cons-

It is difficult to adhere to requires family and social support.
It may not be suitable for all persons who can be associated with side effects.
Very long-term effects are not known.
The keto diet is not balanced.

Caveats:-

The ketogenic diet isn’t something you just dive into on your own. You need a team — a nutritionist, an endocrinologist, maybe a psychologist, and an exercise physiologist, too. People should approach it like any medication: get a proper assessment and some counselling before starting, and keep checking in along the way. Sometimes, you’ll need extra micronutrient supplements, so regular monitoring matters.

Difficult to sustain-

Because of the stringent food restrictions, many find the keto diet hard to stick to.
The ketogenic diet can be effective for weight loss when used for a short period, followed by the adoption of healthier eating habits.

Calorie Depletion and Nutrient Deficiency-

The keto diet eliminates many foods, which means you miss out on important nutrients, vitamins, minerals, and fibre that you’d usually get from fresh fruits, beans, vegetables, and whole grains. Because of this, people often feel tired and mentally foggy. There’s even a term for it: “the keto flu.” And since the diet is low in fibre, constipation is also common.

Bad fat practices-

The high-fat nature of the diet could also have negative impacts on heart health. The American Heart Association recommends limiting saturated fat intake to 5 to 6 percent. “In practice, many people eat high amounts of saturated fats, which could increase cardiovascular disease risk.

Renal Risk:

Patients with kidney disease have an increased risk of requiring dialysis on the keto diet due to the additional ketones that their renal system has to process.
Some people also experience dehydration on the keto diet because they’re eradicating glycogen, which holds water, from their blood.

Food Obsession:-

When you obsess over tracking every bite, you lose touch with what your body actually wants. Instead of listening to your own hunger, you start letting numbers and rules decide what you eat. Honestly, keeping such a close eye on your food can mess with your head. You end up feeling ashamed or stressed out, and that pressure can push you to binge. Then comes the guilt, so you restrict yourself again, and before you know it, you’re stuck in the same exhausting loop.

Here’s what a standard keto diet looks like: Only 5% of your calories come from carbs. That means mainly low-carb vegetables and some leafy greens—no space for bread, beans, fruit, or starchy foods like potatoes. Protein makes up 20%, so think of meat, eggs, and cheese. The largest portion? Fat. That’s 75% of your calories. Pile on foods like oils, real butter, avocado, and unprocessed nuts.

Duration of ketogenic diet:-

There isn’t a clear consensus on how long you should stay on the Keto Diet for obesity or diabetes. It largely depends on your personal goals, your health status, and your ability to follow the diet. Reliable studies indicate it’s safe to use for at least two years, and some people continue even longer to maintain the metabolic benefits.

Conclusion :-

The keto diet can help you drop some pounds, but let’s be real—it’s not magic. Mostly, people lose weight on keto because they eat less and don’t feel as hungry. Here’s the bottom line: the best diet is the one you can stick with for the long haul without wrecking your health. Don’t get caught up in every new fad. Stick to the basics: eat balanced meals, pay attention to portion sizes, get enough sleep, and stay active. Those habits do more for lasting weight loss than any flashy diet ever could.
