If you workout less just eat less total calories.
I like how Matt Fitzgerald puts it in the endurance diet. Eat carb centric and eat until your full. Eat healthy things and occasionally indulge (especially to reward yourself for a food race or excellent training day).
If you’re a cyclist I think it’s easier to lose weight by remaining carb focused but reducing total calorie intake. That way your workouts don’t suck, you can do more of them and the whole thing is more maintainable.
I haven’t worked my self up to this yet, but I’d like to train about 2.5 hours a day on the trainer and eat 10g per kg of body weight a day in carbs. I think at that point my body weight would maintain itself and I’d get in a TON of training.
