When it comes to "the best diet to lose weight" (also known as a "cutting diet"), you'll get A LOT of suggestions as to which diet to lose weight fast you should follow.
However, the truth is that whether it's keto, intermittent fasting, paleo, and so on, all of these diets work by making it easier for you to eat at a calorie deficit.
These diets don't have a "secret" fat loss effect which has been proven time and time again in the literature.
Simply meaning that the best weight loss diet or the best diet for abs for example is the one that you can adhere to the best.
However, weight loss is one thing and fat loss is a whole other variable which is MUCH more important when it comes to improving your physique.
When it comes to optimizing the best fat loss diet, you need to pay attention to how much protein,fats, and carbs you're ingesting on a daily basis.
I go through how to optimize each of these factors to create the best fat burning diet in my video.
I also show a daily nutrition/meal plan (full day of eating) for fat loss with various examples/macros of what I personally eat on a daily basis.
