Diet rich in food may promote satiety and weight loss.
Nearly on a daily basis people ask me if eating beef is healthy. Beef in moderation can be a healthy addition to any diet and it is a great source of iron, vitamins, and protein. Sure it is a source of saturated fat, but fat does not make you fat and it might not be as tied to heart disease as we once thought. In fact, beef
A large study was published in 2017 looked at this very question and a new journal article from 2018 used the same data from the Beef WISE Study (Beef’s Role in Weight Improvement, Satisfaction, and Energy) to look at the same question. The prior study indicated equivalent weight loss between two energy-restricted higher protein diets. One of the diets has 4 or more serving of lean red meat per week and the other has restriction to less red meet. The weight loss in both diets was similar with no significance between the two arms.
The second study used data to compare subjective ratings of appetite (hunger and fullness), food cravings, and diet satisfaction between the diets and determine whether these factors influenced weight loss. Subjective appetite, food cravings, and diet satisfaction ratings were collected
Hunger and cravings were reduced during weight loss compared to the baseline, while fullness was not different from the baseline. The reduction in cravings was greater for beef. Subjects had higher deprivation ratings during weight loss with beef restriction. Participants in both groups reported high levels of compliance and diet satisfaction, but there was no difference between the two groups.
The bottom line: This study is promising but it is far from definitive. Long-term adherence to dietary prescriptions is critical for weight management but may be adversely affected by changes in appetite, food cravings, and diet satisfaction that often accompany weight loss. Higher baseline hunger and cravings should be associated with less weight loss, and greater diet compliance, diet satisfaction, and lower feelings of deprivation should be associated with greater weight loss. Further research is needed to confirm the results.
