Keto, intermittent fasting, veganism, and the Mediterranean diet – there are so many eating styles that have been celebrated for being the best in terms of weight loss. So, which is the real winner? Tommy Martin, MD (@dr.tommymartin) is a medical doctor and influencer with over 2.2 million followers on TikTok. He shares lots of videos about health, ranging from physical to mental, and loves busting myths surrounding diet and fitness. In a recent viral video, he discusses all the trendy eating styles and reveals which is the real winner for weight loss. "The best diet to lose weight that you have to know about," he says in the clip. 

Is It Keto?

"I know you're thinking it is the ketogenic diet, but unfortunately, no, it is not," says Dr. Martin. "Although you will lose weight very fast because a lot of the water weight you lose by reducing carbs, not the ketogenic diet."

Is It the Carnivore Diet?

Is it the Carnivore Diet? "Sorry. No, it's not the carnivore diet either, although you likely will lose weight if you're in a calorie deficit and probably pretty rapidly as you also cut carbs," he notes. 

Is It the Mediterranean Diet?

The Mediterranean Diet, regularly chosen as one of the healthiest diets which involves eating clean and natural foods like healthy fats, lean meats and fish, and lots of veggies, "although a very good lifestyle with tons of whole foods, that's not the diet either," he continues. 

Is It Intermittent Fasting?

"Intermittent fasting, although this is praised and loved by so many, it is not intermittent fasting either," he says, adding that "intermittent fasting does help you get into a window of time to eat where it can make a calorie deficit easier for you."  Intermittent fasting works by "prolonging the period when your body has burned through the calories consumed during your last meal and begins burning fat," explains Johns Hopkins Medicine.

Is It Veganism?

Going vegan is not the solution either. "I mean, there's nothing wrong with it, but it's not going to be superior to any of the other diets in terms of weight loss if calories are equated and you're in a calorie deficit," says Dr. Martin. 

The Best Diet Is One You "Adhere to"

"So what is this diet? Well, my good friend, Lane Norton talked about it today, and I could not agree more: Whether you pick ketogenic, high carb, low carb, intermittent fasting, going vegan, or any other diet under the sun, the most important thing is what diet can you adhere to in the diet that you could adhere to, is the one that you are going to be most successful at in terms of losing weight," he points out.

"So instead of listening to your favorite social media influencer about doing this specific diet to lose weight, pick one that works for you. And if you can create a lifestyle, maintain a calorie deficit, you will lose weight," he concludes.
