Obesity, rising blood pressure, and concerns about appetite and hunger while managing a diet

Recently, as I have gained weight, I am concerned about health issues caused by obesity. In particular, my blood pressure has risen, causing anxiety in my daily life, so I decided to go on a diet. However, now that I have actually started managing my diet, the hardest part is my appetite and constant hunger. I want to exercise as well, but I am deeply worried that the effectiveness will be halved if I do not stick to my diet properly.

I am looking for foods that provide a feeling of fullness while also aiding in weight loss, and I have heard that foods rich in protein and dietary fiber are helpful. For example, I heard that grains and legumes like oats, chickpeas, and lentils help maintain satiety for a long time and have a positive effect on blood pressure management. Also, pairing vegetables with protein foods like grilled salmon or chicken breast can help balance nutrition, and avocados or boiled eggs seem like simple yet filling options.

I believe that dieting is not merely about losing weight, but about maintaining one's health. Overcoming cravings and hunger is not easy, but I want to consistently stick to it by making wiser dietary choices. I am curious to know what foods others with similar concerns use to stay full and manage their diets.
