Oh... and don't shift to artificial sweetened products as snacks. They're just as bad for you in other ways, and will not help you long-term.
I have a shelf of rice snacks. I use them to snack, and I snack all day. I used cup of noodle soups, stuff like that, as it takes you longer to consume, fills you, and keeps you from eating longer, all at around 100 calories per serve.
I sat around the 90kg mark, and all last year my goal was to simply change my eating. I've usually sat a handful of kg over my healthy weight, which for my height and age is 83kg. Doing that last year, I'm now 85kg. I have not dieted, I have simply changed my eating and lifestyle. Keeping busy is important. If you aren't active, you eat, and get fat. Eating when active is entirely different though, and healthy for you, and you do not gain weight when eating right with activity.
This is what I mean about lifestyle. Lifestyle affects your mood, your eating, everything about you from the moment you get up in the morning until sleep at night. Make slow and progressive changes to all the unhealthy aspects of your lifestyle, and you will lose weight without dieting, and simply by eating healthier combined with activity.
People do weird and wonderful shit, all the time telling themselves something is necessary. For example, walking up a hill is a good thing. Taking a protein bar with you is a bad thing. People justify it that they need the calories to sustain their energy whilst climbing the hill, but you do not need a protein bar from a packet filled with crap. You can take numerous things that are better for you, like a small packet of nuts, or make something healthy and take with you in a backpack (cold or hot - apply appropriate device to keep it right in backpack, as plenty of heating cooling options exist). You can even make something before you exercise, leave in fridge, exercise and consume water, which is all you really need, and on return you have healthy calories awaiting you to eat to ensure your body doesn't have issues.
