JJ,
All you have to know is that every time you eat, your body will produce insulin. If you don't use up insulin then it turns to fat. I know it's a lot more complex than this because you have to consider what types of food you're eating, sugar, yadda yadda yadda. BUT WHO HAS THE MENTAL SPACE TO THINK ABOUT THAT ALL THE TIME?
In a nutshell, don't snack all day long. Practice IF (intermittent fasting). 16:8. No eating for 16 hours and then eat a meal in an 8-hour window. I like IF because I'm not depriving myself of any foods. For example, if I want pho and nab vam, I save it for the day when I break my IF. Of course, eating healthy and in smaller portions will expedite weight loss but just saying.
I don't like to work out. It's very boring. What I like to do is stay active, especially walking. You just need 10,000 steps to maintain weight. To lose weight, go at least 15,000+. Call a good friend and talk while you walk. Listen to an audiobook, podcast, playlist, Youtube channel
, etc.
Last but not least, MANAGE YOUR STRESS LEVEL. None of the things I mentioned will ever work if you aren't in a happy place. Surround yourself with positive and uplifting people who are excited to be in your presence. Find something that arouses your passionate side.
