If I eat lower glycemic index foods, I can eat reduced calories without feeling like I'm starving or having hunger cravings. I also consume psyllium husk after a meal, which slows digestion of simple carbs and makes me feel fuller. This helps maintain an even blood sugar and avoid spikes which lead to cravings.
But I have experience with diet and fitness. Other people though aren't so lucky. Some people feel such intense cravings who have no idea what to do and can't maintain a proper diet for shit. I remember taking a medication that jacked up my food cravings like crazy and that reminded me how hard other people have it with dieting.
I found a guy parking like that at work with an overpriced truck like that, so i scoped him out and it ended up being the chief of my division, my bosses' boss. They are paying him too much.
