Keto Diet: Is it as Good as Claimed?
![](/static/keto-diet-8513222db33762e4174fc0676a1dd29c.jpg)
The keto diet, short for the ketogenic diet, is a low-carbohydrate, high-fat diet that has gained popularity recently for its potential health benefits.
The diet involves reducing carbohydrate intake and increasing fat intake in order to put the body into a metabolic state called ketosis, in which the body burns fat for energy instead of carbohydrates.
Advocates of the keto diet claim that it can lead to weight loss, improved blood sugar control, and even a reduced risk of certain diseases such as cancer and Alzheimer’s disease. But is the keto diet as good as it is claimed to be?
Let’s explore the science behind the diet and its potential benefits and drawbacks.
How Does the Keto Diet Work?
The keto diet reduces carbohydrate intake to less than 50 grams daily, typically 20-30 grams daily. This forces the body to enter a state of ketosis, which burns fat for energy instead of carbohydrates.
When carbohydrates are restricted, the body must find an alternative energy source. Normally, the body uses glucose from carbohydrates as its primary energy source. But when glucose is unavailable, the liver produces ketones from fat to be used as energy instead.
By reducing carbohydrate intake and increasing fat intake, the keto diet encourages the body to enter and maintain a state of ketosis, which can lead to weight loss and other health benefits.
How Does a Typical Keto Diet look?
A keto diet consists of high-fat, moderate protein, and low-carbohydrate foods. The goal of the diet is to switch the body’s primary fuel source from glucose (sugar) to ketones produced by the liver from stored fat.
This is achieved by limiting carbohydrate intake to 20-50 grams daily, or less than 10% of total calorie intake.
Foods that are allowed on the keto diet include:
- Meat: Beef, pork, chicken, turkey, and other poultry
- Fish and seafood: Salmon, tuna, trout, shrimp, and other seafood
- Eggs: Including whole eggs with the yolk
- Cheese: Hard cheeses such as cheddar, feta, and goat cheese
- Nuts and seeds: Almonds, macadamia nuts, sunflower seeds, and others
- Healthy oils: Olive oil, coconut oil, and avocado oil
Foods that are restricted on the keto diet include:
- Grains: Bread, pasta, rice, and other grain-based foods
- Fruit: Bananas, apples, oranges, and other high-sugar fruits
- Starchy vegetables: Potatoes, sweet potatoes, corn, and peas
- Sugar: All forms of added sugar, including honey and maple syrup
- Processed foods: Chips, crackers, and other snack foods
Is Starbucks Keto?
While Starbucks offers some low-carb options that may suit the keto diet, most of its menu items are high in carbohydrates and sugar. Many of their drinks are made with syrups and sweeteners that are high in sugar, and their food items often contain grains and starchy vegetables.
If you are following the keto diet and want to visit Starbucks, some options to consider include the following:
- Black coffee or espresso
- Brewed tea or iced tea without sweeteners
- Low-carb drinks made with sugar-free syrups, such as a sugar-free vanilla latte with almond milk
- Snacks such as the Sous Vide Egg Bites or the Cheese & Fruit Protein Box (minus the crackers)
It is important to remember that even low-carb options at Starbucks may still contain hidden sugars or carbohydrates, so it is important to read nutrition information carefully and make informed choices.
Additionally, preparing meals and drinks at home can give you more control over ingredients and nutrient content.
Potential Benefits of the Keto Diet
Weight Loss: One of the main reasons why people try the keto diet is for weight loss. Several studies have shown that the keto diet can lead to significant weight loss, particularly in the short term.
A 2013 study published in the British Journal of Nutrition found that obese adults who followed a keto diet for 8 weeks lost an average of 13 pounds, compared to 6 pounds in those who followed a low-fat diet.
Improved Blood Sugar Control:
The keto diet may also benefit those with type 2 diabetes or insulin resistance. Reducing carbohydrate intake in the diet can improve blood sugar control and insulin sensitivity. A 2018 study published in the Journal of Medical Internet Research found that individuals with type 2 diabetes who followed a keto diet for 10 weeks experienced significant improvements in blood sugar control and weight loss.
Reduced Risk of Certain Diseases:
Some studies suggest that the keto diet may be beneficial for reducing the risk of certain diseases, such as cancer and Alzheimer’s disease.
A 2018 study published in the Journal of Lipid Research found that the keto diet may effectively reduce the growth of certain types of cancer cells.
A 2019 review published in the Journal of Alzheimer’s Disease found that the keto diet may improve cognitive function in individuals with Alzheimer’s disease.
Potential Drawbacks of the Keto Diet
Nutrient Deficiencies: The keto diet may lead to nutrient deficiencies, particularly in vitamins and minerals found in carbohydrate-rich foods. For example, fruits, vegetables, and whole grains are rich in fiber, vitamins, and minerals but are restricted to the keto diet.
This can lead to important nutrients such as vitamin C, folate, and potassium deficiencies.
Difficulty Sustaining the Diet: The keto diet can be difficult to sustain long-term, as it requires significant changes to eating habits and can be socially isolating.
Additionally, some people may experience negative side effects such as headaches, fatigue, and constipation when starting the diet.
It may not be Appropriate for Everyone
The keto diet may not be appropriate for everyone, particularly those with certain medical conditions such as pancreatic or liver disease.
Additionally, pregnant or breastfeeding women should avoid the keto diet, as it can lead to nutrient deficiencies for both the mother and baby.
High Fat Intake:
The high fat intake required on the keto diet can also be a concern for some individuals, particularly those with a history of heart disease or high cholesterol. While the keto diet may improve blood lipid levels in some individuals, it can also increase LDL cholesterol (the “bad” cholesterol) in others.
Conclusion
The keto diet has recently gained popularity for its potential health benefits, particularly weight loss and improved blood sugar control.
While some studies suggest that the diet may also be beneficial for reducing the risk of certain diseases, more research is needed to understand the long-term effects of the keto diet fully.
However, the keto diet also has potential drawbacks, such as nutrient deficiencies, difficulty sustaining the diet, and the potential for negative side effects.
Additionally, the high fat intake required on the diet may not be appropriate for everyone, particularly those with a history of heart disease or high cholesterol.
Ultimately, whether the keto diet is “as good as claimed” depends on the individual’s specific health goals and needs.
Before starting keto or any other diet, speaking with a healthcare provider to determine if it is safe and appropriate is important.
