Even at 2lbs a week it takes around 4-5 months to lose 30-40lbs, and a 2lb a week weight loss is HARD. That’s a 1000 calorie deficit a day. I’ve done it, I barely ate more than 1000 calories a day and I felt like trash.
You won’t notice a difference in the mirror for a while. As in for SEVERAL MONTHS. what you want to do is lose weight sustainably. 0.5-1lb a week, which is a 250-500 calorie deficit. So if you burn 2000 calories in a day, you would eat 1500-1750 calories. It’s easier, it’s more sustainable and slower weight loss encourages skin to retract properly.
Instead of thinking about your goal day, you have to envision the rest of your life. This journey isn’t for next month, or next year, it’s for the rest of your healthy, happy life! You are doing this so you can be your best self all the way until your old age. When you think of it that way, 6 months to a year of dedicated gradual weightloss isn’t such a sacrifice.
