Q.My friend says I should do a keto diet to help with my weight loss. What is it, and is it better for weight loss?
A. A ketogenic (keto) diet is high in fat and protein and low in carbohydrates. Most of the body's cells prefer to use blood sugar (glucose) as their main source of energy. The keto diet forces your body to use a different type of fuel. Instead of providing your body with glucose from carbohydrates, the keto diet relies on the liver to break down stored fat into molecules called ketones. (This process is called ketogenesis; that's where the diet's name comes from.)
For most people to begin using stored fat as fuel, they need to limit daily carbohydrate intake to fewer than 20 to 50 grams depending on body size. (For comparison, a medium-sized banana has about 27 grams of carbs.) But this is a highly individualized process, and some people need a more restricted diet to begin producing enough ketones. It typically takes two to four days to reach a state of ketosis (when fat becomes a main source of energy).
There's no shortage of keto-inspired diets. The Atkins, South Beach, and Paleo diets are some of the best-known examples. But a true ketogenic diet is different and calls for up to 90% of your daily calories to come from fat. That is often hard for people to maintain. However, research has shown that people can achieve faster weight loss with a keto diet compared with a calorie-reduction diet. In the short term, a keto diet is probably safe. But over time, it's tough to keep off the weight this way.
If you do try a keto diet to jump-start weight reduction, choose healthier sources of fat and protein, such as olive oil, avocados, and nuts (almonds, walnuts). But after a few weeks, switch to a reduced-calorie Mediterranean-style diet and increase your physical activity. This will help manage your weight loss for the long term.

Average adult human weight varies by continent, from about 60 kg (130 lb) in Asia and Africa to about 80 kg (180 lb) in North America, with men on average weighing more than women.

Ketogenic diets can help patients lose about 2 kg more than low-fat diets do at 1 year, but higher-quality studies show no difference. Weight loss peaks at about 5 months but is often not sustained.
However, a new study presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology suggests that a “keto-like” diet may be associated with higher blood levels of “bad” cholesterol and a twofold heightened risk of cardiovascular events such as chest pain ( ...
The rate of weight loss on the keto diet without exercise ranges from 1-2 pounds per week. Therefore, if you want to lose significant weight, reaching your goals may take a few months. Exercise is essential to any weight loss plan, as it helps burn calories, build muscle, and improve overall health.
Here are the basics. The keto diet aims to force your body into using a different type of fuel. Instead of relying on sugar (glucose) that comes from carbohydrates (such as grains, legumes, vegetables, and fruits), the keto diet relies on ketone bodies, a type of fuel that the liver produces from stored fat.
Research has shown that ketosis may have several health benefits. One of the biggest benefits of ketosis may be weight loss. The process can help you feel less hungry, which may lead to eating less food. It can help you lose belly fat (visceral fat) while maintaining a lean mass.
Giving up whole grains, beans, fruits and many veggies can cause nutrient deficiencies and constipation. Common short-term side effects include fatigue, headache, brain fog and upset stomach, aka “keto flu.” Long-term health risks include kidney stones, osteoporosis and liver disease.
The keto diet could cause low blood pressure, kidney stones, constipation, nutrient deficiencies and an increased risk of heart disease. Strict diets like keto could also cause social isolation or disordered eating. Keto is not safe for those with any conditions involving their pancreas, liver, thyroid or gallbladder.
Q: Who is NOT a candidate for the keto diet? A: Anyone with a chronic condition such as diabetes, high blood pressure or metabolic syndrome should avoid following a ketogenic diet. Plus, since the fat content hovers around 75 percent, it's a red flag for people who have heart disease.
“If the patient can maintain a steady calorie deficit, I expect them to lose one to two pounds per week,” says Dr. Seeman. So after 12 weeks, her clients are usually down around 20-25 pounds.
To maximize weight loss on a ketogenic diet, get adequate sleep, reduce stress, be more active and consume whole, nutritious, low-carb foods whenever possible.
If a person follows the 75% fat /20% carb/5% fat keto diet, average results may look like this: Weeks 1–2: rapid weight reduction phase due to water loss – up to ten pounds. Weeks 2–4: standard weight reduction – between one and two pounds per week. After the first month – slow weight loss – around one pound per week.
One of the main criticisms of this diet is that many people tend to eat too much protein and poor-quality fats from processed foods, with very few fruits and vegetables. Patients with kidney disease need to be cautious because this diet could worsen their condition.
That plan is called the 30-30-30 rule. It's a simple but catchy idea that encourages you to eat 30 grams of protein within 30 minutes of waking up and then get 30 minutes of low-intensity exercise. The 30-30-30 rule now has millions of followers on TikTok.
Usually, when a person does not lose weight on the keto diet, it is because they have not achieved ketosis. One reason for not achieving ketosis is not cutting back enough on carbs. According to a 2023 overview of previous research.
