Taken form the following study: A systematic review and meta-analysis of interval training versus moderate-intensity continuous training on body adiposity.
Exercise combined with diet modifications has been shown to be more effective than either alone for promoting weight loss.
So what exercise works better for weight loss? High-intensity interval training (HIIT) or sprint interval training (SIT) with moderate-intensity continuous training (MICT).
HIIT and SIT result in similar reductions in body fat percentage and total body fat mass as MICT, especially when matched for energy expenditure.
These results show that the type of cardio performed for fat loss (intervals vs. steady-state) probably doesn’t matter as much as the number of calories burned in the exercise session.
A focus should also be placed on whether you can see yourself sticking with your chosen exercise modality for the long-term.
Some form of exercise is better then no exercise.
