People go on diets all the time. Sadly, they’re often ineffective for one reason or another. Perhaps the diet was based on unhealthy principles and was unsustainable. Maybe the dieter tried to do too much too fast and wound up getting frustrated and quitting. Regardless of the reason, dieting isn’t really the best way to lose weight in the first place. Instead, you should strive to adopt a healthy diet over time that focuses on feeling good, not necessarily on weight loss.
First things first: don’t try to do everything at once. Switching from an unhealthy lifestyle to a healthy one isn’t something you can do overnight. There will be slipups and that’s okay. Instead, focus on changing one small thing at a time. Once that becomes a part of your routine, gradually add one more thing and then another until your diet is healthy and you’re shedding pounds.
