Intermittent Fasting and Keto: Which is Better for Weight Loss?

SadaNews - Intermittent fasting and the keto diet are among the most popular regimes in recent years among those seeking to lose weight and improve their health. Both methods share a common primary goal, which is to stimulate the body to burn fat, but they achieve this in different ways.

Nutrition experts, in a report on the "VeryWellHealth" health site, explain that fat burning may be similar between the two methods, but intermittent fasting may be easier to maintain in the long term for many individuals.

Intermittent fasting does not focus on the quality of food as much as it focuses on the timing of consumption, relying on specific periods during which a person refrains from consuming calories, followed by periods in which eating is allowed.

Some of its most famous patterns include alternate day fasting, which means complete fasting for 24 hours alternately, the 5:2 system where two days a week are fasted while consuming very few calories, and the 16:8 system where food is consumed within just 8 hours daily, fasting for 16 hours.

This method aids in what is known as metabolic switching, where the body shifts from using glucose as its primary energy source to burning fat and ketones.

Some studies indicate that intermittent fasting may contribute to weight loss, improve blood sugar levels, and lower blood pressure.

As for the ketogenic (keto) diet, it relies on significantly reducing carbohydrates and increasing fat intake with a moderate amount of protein. Carbohydrates are typically reduced to 50 grams or less daily, which is roughly equivalent to two to three slices of bread.

When carbohydrates are reduced to this level, the body enters a state known as ketosis, where it begins to use fat as the primary energy source instead of sugar.

Some research suggests that keto may contribute to weight loss and reduce appetite, and it may improve certain blood sugar and cholesterol markers.

Which is Better for Fat Burning?

Both methods lead to fat burning, but the mechanisms differ; intermittent fasting dictates when you eat, while keto determines what you eat.

Some studies indicate that overweight individuals may lose around 3 to 4 kilograms when following intermittent fasting, with most of this weight typically coming from fat.

On the other hand, keto may lead to rapid initial weight loss, but this pace often slows after several months, making weight loss resemble that of other diets.

One of the key differences between the two methods is the potential for sustainability. Keto may be challenging to adhere to for extended periods due to strict restrictions on carbohydrates, difficulties in social scenarios, and feelings of boredom from limited food choices.

In contrast, intermittent fasting may be more flexible as it does not impose strict restrictions on the type of food but focuses solely on meal timing. The 16:8 system is one of the most sustainable patterns as it resembles the natural eating patterns of many people.

Despite the popularity of these two methods, nutrition experts emphasize that neither intermittent fasting nor keto is suitable for everyone.

It is advisable to consult a doctor or a nutrition specialist before following any new diet, especially for individuals with diabetes, heart disease, eating disorders, or chronic health conditions. The best diet is one that fits a person’s health status and can be maintained long-term.
