Similar Assertions

If you're lean and work out with weights, taking two days a week to eat more carbs doesn't seem to slow down fat loss compared to cutting calories all the time — both ways lose about the same amount of fat in 7 weeks.

If you're already lean and lift weights, taking two days a week to eat normal calories—especially from carbs—while cutting calories the rest of the week might help you keep more muscle compared to cutting calories every day.

If you're fit and lift weights, cutting calories most of the week but eating more carbs for 2 days might help your body burn calories at rest better than cutting calories every day — like keeping your metabolism from slowing down too much.
