To a lot of people it would be a dream come through to be able to lose weight without the need of exercise. I’ve touched the subject briefly through my posts on weight loss without hassle and why you need to prioritize nutrition before exercise but an american study might be even more helpful.
In the study, they went through data from National Longitudinal Survey of Youth (NLSY) and looked at people reading labels and doing exercise to find out which method makes the most people succeed with their weight loss.
Label users who did not exercise displayed a slightly greater likelihood of weight loss than those who exercised but did not read food labels. Additionally, those who only read labels were more likely to improve their chances of weight loss by adding exercise to their routines rather than abandoning label usage in favor of exercise.
As you can see, people reading labels are more likely to succeed than those just exercising. You are most likely to get the best results by combining them.
