How It Works
Weekly deficit = (low-day deficit x low days) + (high-day deficit x high days). We divide by 7 for the average daily gap and apply the 3,500-calorie-per-pound rule over the chosen weeks to get projected loss. The flat line uses a constant 500-calorie daily deficit for comparison. Because both use similar average gaps, the curves land close; cycling's value is psychological and hormonal relief on high days, not a mathematical edge.
What Should You Do?
Use cycling if a steady deficit feels monotonous or your training has heavy and light days. Set high days as mild deficits or true refeeds rather than full blowouts, or the weekly deficit collapses. Keep the average gap near your goal (roughly 350-700 calories) for steady, sustainable loss. Track weekly average weight, since day-to-day swings from cycling water and glycogen can be large.
Frequently Asked Questions
Does cycling burn more fat than flat dieting?
Not by the math; both depend on the average weekly deficit. Cycling helps adherence and may ease hunger, which indirectly helps.
What should high days look like?
Often a smaller deficit or maintenance. Some use slight surpluses on training days, but large overeating erases the weekly gap.
Why are the two lines so close?
Because the average daily deficit is similar. The chart shows cycling is a pacing choice, not a shortcut.
Is cycling good for athletes?
Yes, matching low days to rest and higher days to hard training can support performance while still losing fat.
Will the scale jump on high days?
Expect water and glycogen bumps from extra carbs; judge progress by weekly averages, not daily weight.
