In terms of weight loss, it’s okay to shoot for 0.5-2lb body weight loss increments. In fact a healthy rate of weight loss will create the biggest impact.
When it comes to your dietary pattern, you don’t have to cut out every single food you love. Just move more towards eating more plants and eating fewer ultra processed foods. Your diet doesn’t have to be so drastic that it’s miserable and you quit.
When it comes to exercise, you certainly do not want to start from 0 hours a week and go straight to 7+ hours a week. That’s a sure fire way of quitting within a few weeks, or even days.
Those small steps you implement/aim for.. they add up to big changes given time and consistency.
