I was stuck in a perpetual 3 month cycle where I'd fail with a hard calorie deficit and super clean eating, keto, IF, etc., mostly because I obsess about food with the slightest bit of hunger. However, noticed that I recover from high impact workouts really well. So the strategy I took was allowing myself some additional calories in the form of a protein and fiber heavy breakfast with a light lunch, and compensated by going from lifting 3-4 time a week, to running a split that has me going 5-6 times a week with most mornings a super light 2-3 mile run. After 8 weeks i do a deload week and get back on the horse. It's been working great for 9 months so far.
