What is the best diet?
The Oxford dictionary says a diet is the kinds of food that a person, animal, or community habitually eats. Examples are keto, vegetarian, pescatarian … low carb, low fat.
There are plenty of diets out there and currently intermittent fasting, keto, vegetarian and vegan are the most popular.
No diet is inherently good or bad, they all do what they’re supposed to do. At the end of the day, they will help you lose weight if done correctly.
What it comes down to is you as an individual. Is this something that you can maintain for a long period of time, or are you just on a diet to meet a short term goal?
At the end of the day what it really comes down to is your energy balance. If you’re eating less than what your body requires, then you’re going to lose fat. If you’re eating more, depending on how much more and if you’re weight training, then you’ll either build muscle or you’ll put on some fat. If your goal is weight loss, it really doesn’t matter what type of diet that you are partaking in, it really just depends on how much you’re eating and if you’re meeting your caloric and macro requirements.
So you need to figure out what it is that your body requires. So what is your basal metabolic rate? How much energy does your body actually need to live?
Then on top of that, what is your total daily energy expenditure? If you’re a carpenter you might be on your feet all day, moving around a lot, as opposed to someone who’s in an office, who presumably just sits down for a lot of the time, they’re not burning as many calories just through general activity.
There are equations to figure these numbers out. Once you know this, you need to figure out whether you’re going to be in a deficit, if you’re looking to lose fat, or a surplus if you’re looking to gain muscle.
Choosing a diet that you can do long term is really the ideal situation.
The realistic answer is that there is no best diet for everyone. Individuals should be doing what works best for them, and it’s up to you to decide what that might be.
Read up on a particular diet and if you think that it might fit in with your lifestyle, your beliefs, your religion then go for it. Try it out, see what works.
If you find that it’s not sustainable, or you actually don’t enjoy it then move on to the next thing and play around with it.
At the end of the day, know what your goals are and what fits into your lifestyle.
