I have a similar story, was 250, now 160. For me, it was entirely based on calories in and calories out. Burn more than you put in and you will lose weight. The trouble I had was in making a life style change to eating habits so that I get all the necessaries in a small calorie package. Huel helped me get there. It’s easy to count and has all the goodies. I started with one shake for breakfast. Start slow with Huel. Getting a proper amount of fiber in your diet can take time for your body to adjust. Currently I have a shake for breakfast and lunch. For dinner I have either a huge portion of veggies and 4oz of chicken or fish, or I’ll have another shake. For my size and age (43, 160) I’m taking in 1200-1400 calories a day and slowly losing the last few pounds. I started Huel at 220. I was taking in 1800 calories a day and losing 2lbs a week or more. It gets slower and harder the closer you get to that healthy goal.
I made zero changes to my exercise, meaning I don’t exercise, but I do have a physically demanding job.
I’ve recently started a little bit of intermittent fasting and it’s helped get me past the night time snacking. I basically have breakfast at lunch, lunch at dinner, and dinner during the danger times when I’d usually just hit the fridge, cabinets, etc for any snack I could stuff in my face. At least this way I’m eating healthy when I’d normally be fighting the urge to get another snack and I’m not blowing out my calorie budget for the day.
I don’t know that it’s the right way to do it but it’s working for me.
Welcome to the club! Hope you have as much success as I’ve had!
