Is It Possible to Target Fat Loss to Specific Body Parts?

Check out this answer from Consensus:

The evidence suggests that while targeted fat loss to specific body parts is possible to some extent through localized resistance training combined with endurance exercise, overall fat loss remains a more effective approach for improving health markers. Distinct lifestyle interventions, such as specific diet plans and exercise regimens, can differentially affect various fat depots in the body. Tailored programs that consider individual preferences and motivations, especially in hard-to-reach populations like men, may enhance the effectiveness of weight loss interventions.

The concept of targeted fat loss, often referred to as “spot reduction,” is a popular topic in fitness and health discussions. Many individuals seek to lose fat in specific areas of their body, such as the abdomen, thighs, or arms. This article explores the scientific evidence behind the possibility of targeting fat loss to specific body parts through various exercise and diet interventions.

Evidence from Research

Localized Fat Loss through Exercise

A study by1 investigated the effects of combined resistance and endurance exercise training on regional fat loss. The research involved 16 physically inactive women who were divided into two groups: one focusing on upper body resistance exercises followed by cycling, and the other on lower body resistance exercises followed by arm-ergometer workouts. The results indicated that the group performing upper body exercises experienced a greater reduction in upper limb fat mass, while the group focusing on lower body exercises saw more significant fat loss in the lower limbs. This suggests that localized resistance training, combined with endurance exercise, may indeed target specific adipose tissue sites.

Global vs. Regional Fat Loss

In contrast, another study2 examined the effects of total and regional fat loss on inflammation markers in overweight and obese older adults. The findings revealed that while regional fat loss (specifically abdominal fat) was associated with reduced inflammation, global measures of adiposity were better predictors of changes in inflammatory burden. This implies that overall fat loss might be more effective in improving health markers than focusing solely on regional fat loss.

Lifestyle Interventions and Fat Mobilization

A comprehensive study3 assessed the impact of different lifestyle strategies on specific body adipose depots. Participants were subjected to either a low-fat or Mediterranean/low-carbohydrate diet, with or without added physical activity. The results showed that while moderate weight loss was achieved across all groups, exercise combined with diet had a more significant effect on reducing visceral adipose tissue (VAT) and intrahepatic fat. The Mediterranean/low-carbohydrate diet was particularly effective in mobilizing fat from specific ectopic depots, such as the liver and pericardial regions. This indicates that distinct lifestyle protocols can uniquely induce fat mobilization from specific anatomical sites.

Male-Focused Weight Loss Programs

A study4 explored the experiences of overweight and obese men participating in a sport-based weight loss intervention. The MAN v FAT Football (MVFF) program, designed for men with a BMI of 27.5 or higher, encouraged weight loss through participation in a football league. The program’s appeal lay in its competitive, team-based environment, which resonated with male participants. While the study did not specifically address targeted fat loss, it highlighted the importance of tailored interventions that consider gender-specific preferences and motivations.

This is a complex question, technically there is no way to selectively burn fat in a specific area. Similar to the idea that we cant choose where we gain fat, as this depends on hormones, genetics, and gender, we cant target fat burning in the body. For example, performing abdominal exercises alone will results in less abdominal fat loss then performing whole body exercise, such as running. Thus, even though you target this region with a specific exercise it still comes down to how much energy is being burned that determines overall fat loss. That being said, when looking at specific fat depots, such as visceral fat vs subcutaneous fat, there is evidence that performing both aerobic and/or resistance exercise results in greater loss of visceral fat compared to a diet alone. Additionally, during weight regain if aerobic or resistance exercise is performed there is less regain of visceral fat compared to individuals that perform no exercise. Thus, although we technically can not target fat loss in a specific part of the body there are strategies that can be performed that impact specific fat depots in the body.

To most of our disappointment, fat cannot be targeted, mobilized and used from specific areas – such as the thighs, stomach and buttocks. Fat is used during exercise at relatively ‘low’ amounts – somewhere between 0.2g to 0.8g a minute (this can go as high as 1.5g/min in ‘fat adapted’ endurance athletes). And, despite our best efforts to perform exercises for areas where we would like to lose fat (such as sit-ups, lunges and leg lifts), humans utilize fat from all over the body during exercise and not just the site we are training. This is largely dependent on genetics, gender, age, race, blood flow and hormones and is currently thought to be unresponsive to any known intervention (exercise, diet etc).

Fat generally follows the principle of ‘first on, first off’ and it is not possible to target fat loss to just one part of the body with exercise. If that were the case, then tennis players would have less fat on the arm of their dominant arm from the repeated exercise that arm gets from hitting a ball with force – they don’t – they have similar levels of fat on both arms.

There is no such thing as “spot reduction,” i.e., reducing fat in a specific region as a result of exercising the muscle groups in that region. 

The biochemical processes responsible for fat breakdown (lipolysis) and fat loss (fatty acid oxidation) are based on energy deficits that release hormones that bind to fat tissue receptors throughout the body and are not based on the location of the specific muscle groups being exercised.

Spot reduction, or the ability to lose body fat in a desired location, is a common exercise misconception. Performing a lot of sit-ups or abdominal exercises will strengthen and firm the underlying abdominal muscles, but will have little to do with losing the fat in that specific area.

Generally the answer is no; however, we have a trial ongoing that is using high intensity strength training that is designed to increase muscle mass and decrease fat mass in the thigh. We will have the answers by January 2019.
