8 basic tips:
So that you can eat better from now on in your life (remembering that eating well is a fundamental healthy lifestyle habit):
1 - Adopt and maintain good lifestyle habits (no good diet works on its own).
2 - Drink water every hour, even if you're not thirsty.
3 - Have a good breakfast.
4 - Eat no more than every 3 hours (many people need even shorter intervals, depending on their metabolism).
5 - Eat fiber every day, at least in 2 meals (and try to vary them).
6 - Look for higher quality food.
7 - Reduce the total carbohydrate load in your diet.
8 - Seek regular monitoring by a good nutritionist - after all, if each person is unique (individuality), there's nothing more obvious than each person having specific needs that require specific attention and the necessary adaptations.
