Why diet is just as important as exercise?

Have we not heard about its 70% diet and 30% workout or the other way it is 30% diet and 70% workout well to be honest and to answer why diet is as important as exercise is simple, unless you are not providing your body with the right type of essentials, how do you expect from it to get you throughout the day or even months.

Let’s take it from the top, why diet is just as important as exercise?
Because:

Diet helps in losing or gaining weight while exercise provides benefits that help sustain your results. Hand in hand both exercise and diet can help reduce the diseases and help you in building muscle or losing weight and even helps in making mental health better.

When you think about what you are eating and you feel guilty it certainly makes you feel like it is as important as me not skipping my reps or sets right? So eventually if we were to be honest to ourselves it is a 50-50 ration that we need to follow both religiously in order to attain results.

While it may be easier to manage how many calories you consume, regular exercise helps preserve lean muscle and burn additional calories. Therefore, both diet and exercise are important for weight loss, and combining the two will optimize results.

A person can change one's body composition through diet alone without exercise. However it's the combination of both that provides a complete healthy package. Applying the 80% nutrition-to-20% fitness rule is simply a statement of the importance of nutrition in the equation. This distribution isn't scientifically proven. It is based on the fact that it is easier to consume calories versus burning calories i.e don’t eat what you can’t burn.
If you want to lose weight do not go overboard with your calories, because eventually if you are eating 3000 kcal a day and you are burning 900 at the gym and about 500 more throughout the day you will never go into calorie deficit and hence never end up losing weight and it goes same for weight gain if you are burning more calories and eating less right calories then again no results will be there.

It is not just about eating or working out it is about eating right and working out right too and they both eventually go hand in hand.
