I’m actually doing something very simple. I have changed my daily energy balance by 200-300 calories through a combination of slight portion reduction and mild excercise. That allows me to reduce my weight by around 3/4 lb per week.
Knocking off 50-75 calories per meal is actually very easy to do and a 20-30 minute walk added is also easy. Adds up to the target goal each day without really trying.
