According to the prevalence of respondents eating less or moving more to lose weight survey, the groups across all the categories of healthy, overweight, and obese which experienced the highest average weight loss were the ones who both ate less and moved more.

That statement is false.

According to the surveys, people who experienced the highest average weight loss are the one who is eating 'proper foods' rather than the one that eating less. Eating proper foods would give us more energy towards the day and make our body burned more fats while keeping the muscles.
