May benefit those unable to exerciseīecause IIFYM takes physical activity levels into account when calculating macros, a person who gets limited or no exercise may find the diet useful.

People looking to gain weight may also be able to meet their goals with IIFYM. Similarly, increasing calorie consumption leads to weight gain. People may achieve this by following the IIFYM diet. This often involves cutting around 500–750 calories each day. Losing weightĪ person usually loses weight if they burn more calories than they take in. The aim of the IIFYM diet is to make meals more enjoyable, and meal planning less stressful, which may increase the likelihood of sticking to the diet. It encourages people to eat diverse foods, as long as they do not exceed their macro targets. The IIFYM website promises “no more dieting” and “no more restrictions.” It is advertised as a more flexible dieting stylebecause it incorporates more foods than many other diets. Share on Pinterest The IIFYM diet aims to make meals enjoyable and stress-free. carbohydrates: this value comprises the remaining calories from the adjusted macros score.fat: calculate at about 0.25–0.4 g per lb of body weight.protein: calculate this intake at around 0.7–1.0 grams (g) per pound (lb) of body weight.The final step is to divide the resulting value into what the website calls “adjusted macros.” This will determine how many macros a person needs, based on their current body weight: Subtract 15–20 percent of the TDEE to find out, according to the IIFYM website, how many calories a person should eat per day to achieve their weight loss goals. Step 3: Adjust calorie needs for desired weight The IIFYM website also provides a TDEE calculator. This measurement is called total daily energy expenditure (TDEE).Ī person can calculate their TDEE using an online calculator, which automatically factors in their BMR. The next step involves factoring in the average physical activity level, as this affects the number of calories that the body uses. Step 2: Adjust calorie needs for activity level for women, BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161.for men, BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5.This energy goes toward essential functions, such as breathing, circulation, and body temperature.Ī person can determine their BMR with an online calculator that uses the Mifflin-St. Start by using the calculator on the IIFYM website or by following the steps below:Ī person’s basal metabolic rate (BMR), or resting metabolic rate, is the amount of energy, in calories, that their body needs at rest for 24 hours. The targets and figures vary, based on factors such as age, sex, weight, height, and activity levels.
