There is no one size fits all answer to this. The amount of nutrition per day that is ideal for you depends on a whole host of factors, such as your t. Do you gain weight quickly or are you just struggling to get to your ideal weight?
But what you want to achieve is also an important factor. For example, do you want to lose weight or do you want to have enough energy for your workout, .... ?
The most important thing in determining how many snacks it's best to eat (or not eat) is common sense. Of course, you need fewer snacks if you're in the office for an entire day than if you're going for a hike in the mountains.
Which is not to say you shouldn't snack during an office day, quite the contrary. Because office work also requires energy, and your concentration and energy levels need to be maintained. You will just need smaller amounts.
Small amounts of food during the day will ensure that your energy is nicely distributed throughout the day and will keep you from reaching for large unhealthy meals in the afternoon because you are so hungry.
But choose healthy snacks with plenty of useful nutrients and complex carbohydrates that release their energy slowly.
Also remember to drink enough water, 1.5 to 2 liters of water a day is what an adult needs. Hunger is often mistaken for thirst, so make sure your body is adequately hydrated. You will be less inclined to raid the candy machine throughout the day and will be able to enjoy your healthy snacks in a controlled manner between meals.
Conclusion
How many snacks you can eat per day varies greatly from person to person and depends on a number of factors. Use common sense and realize that you need smaller amounts on days when you are physically less active. Always choose healthy snacks that really nourish your body and give you energy spread throughout the day, so you don't reach for locks of coffee and quick sugars just to have enough energy anyway.
Above all, enjoy healthy!
