Behavior Modification Nutritionists and Dietitians
What is behavioral modification?
Behavioral modification in diet and nutrition involves using targeted strategies to change food, weight, and exercise behaviors, rather than relying on invasive options like surgery or medications for weight loss. This approach recognizes that behaviors leading to conditions such as obesity are often influenced by one's environment. Therefore, a key component of behavioral modification is creating an environment that supports weight management goals. For example, planning meals for the week and making a grocery list of healthy ingredients can help set oneself up for success. This reduces the temptation to rely on fast food or quick, less healthy options, ensuring healthier choices are more accessible and convenient.
Who is behavioral modification for?
Behavioral modification is an accessible and affordable approach to weight management and is thus a great option for many individuals looking to make lifestyle changes. Because behavioral modification is less invasive than other weight loss options, it is often the first line of treatment for individuals who are overweight or at risk of becoming overweight. If behavioral modifications alone are not sufficient to help achieve weight loss goals, then additional strategies, such as medication, may be pursued.
How long does it take to see results from behavior modification?
The length of time it takes to see results from behavior modification can vary significantly depending on the type and success of the behavior modifications made. Experts estimate that it takes about 2 months for behaviors to become habitual or automatic, so weight loss results from behavior modifications often take time and prolonged commitment to ensure results. While a behavioral change such as a drastic reduction in calorie consumption may promote weight loss within weeks instead of months, if an individual cannot sustain the dietary changes, then they will often not obtain lasting lifestyle changes. Therefore, many nutrition experts recommend that individuals start slowly with behavior modifications in order to ensure that the changes that they are making are sustainable, even if this means that it will take longer to see results in weight reduction.
Can a dietitian help with behavior modification for weight loss?
Dietitians can be a great resource for clients pursuing behavioral modifications for weight loss, as they help individuals stay accountable to their goals. Accountability is a key component of behavioral modification, often involving tracking food intake or exercise routines. Dietitians can review these journals, suggest changes, and offer strategies to help clients adhere to their behavioral modifications. Dietitians can also be particularly helpful to clients who have struggled to make successful changes on their own. The added accountability of working with a dietitian can be a valuable resource before considering more invasive weight loss options, such as surgery or medication.
