This age-related drop in calorie burn is in most cases maximum noticeable to your 60s and past, Dr. Roberts stated, in all probability manifesting in weight acquire or a much less tough urge for food.

However as you grow older, it’s necessary to be sure you’re getting the proper stability of vitamins, Dr. Roberts stated.

As an example, analysis means that starting to your 50s, your frame wishes extra of sure vitamins akin to calcium, nutrition B6, nutrition D and protein, although you’re most likely consuming fewer day-to-day energy total.

As a result of that, Dr. Siega-Riz stated, you’ll wish to commit extra of your day-to-day calorie funds to meals that provide you with a larger bang on your greenback nutrient-wise, like end result, greens, complete grains and lean resources of protein.

Dr. Roberts agreed.
