Intermittent fasting involves consuming all the calories over a set period of time and then fasting for the rest of the day.

There are different methods of intermittent fasting, the most common being an 8:16 split — which means you consume your calories in an eight-hour eating period and fasting for another 16 hours of the day.

You can also do a 10:16, 16:10, or even 6:20 split Eating: Fasting. The concept is that you will eat fewer calories because you are squeezing them into a narrower time frame, rather than consuming them throughout the day.

ketogenic diet

In recent years, the ketogenic diet has been one of the most discussed and discussed diets.

Keto, as it’s called for short, prioritizes fat (65-75 percent of daily calories), with moderate consumption of protein (20-30 percent) and little carbs (only about 5 percent, although some versions prohibit carbohydrates (totally).

The Keto Diet ranks as the sixth most popular diet on the internet, with an average of 44,000 monthly searches around the world.

The keto diet is designed to keep the body in a near-constant state of ketosis, a metabolic state in which the body produces ketones from fat to use as energy instead of sugar from carbohydrates (the body’s primary and preferred energy source).

The keto diet has become more and more popular in the past few years, especially with the Hollywood elite, where celebrities like Vanessa Hudgens and LeBron James have committed to the keto diet.

It is important to note that none of these options represent everything, and the end of it all to your health needs. You can lose weight on any diet, as long as you are in a calorie deficit (ie you burn more calories than you consume).

Prioritize calories first, then choose a diet pattern based on your preference.

Studies have also shown that food quality is as if no more important than the number of macronutrients (protein, carbohydrates, and fats) you eat.

In other words: If you’re on a low-carb diet, you need to make sure you’re eating high-quality fat and protein as well.

In contrast, choose whole grains over refined starches if you’re on a diet low in fat.

Advantages:

  • There have been claims that keto may help treat cancer and even respiratory diseases
  • Can lead to weight loss and lower blood sugar in diabetics

Negatives:

  • Several studies indicate that keto is no more effective for weight loss when calories match other diets
