If you're struggling to gain weight, you might think a fast metabolism is to blame. How fast or slow your metabolism is mostly comes down to genetics, but you can slow it down (or speed it up) a little with diet and lifestyle changes. [1] X Trustworthy Source Harvard Medical School Harvard Medical School's Educational Site for the Public Go to source Decreasing your body's metabolic rate helps you gain weight more efficiently by sparing macronutrients that would otherwise be consumed to generate energy in cellular metabolism. The main way to gain weight is to increase your intake of calorie- and nutrient-dense foods and consume more calories each day than your body burns through metabolism and exercise. However, this isn't always as simple as it sounds, especially if you think you might have a naturally fast metabolism or if you are constitutionally thin. Read on to learn how you can decrease your metabolism to help you gain a few needed pounds.
Things You Should Know
- Eat more calories than you burn if you want to gain weight. Aim to add a total of 300 to 500 calories per day above what you normally eat.
- Choose foods that are high in healthy fats and carbohydrates, such as rice, pasta, and red meat. Snack on nuts and seeds, as well, for their content of linoleic acid and magnesium.
- Use relaxation techniques such as meditation or yoga to help cope with stress. More quality sleep can also bring your metabolism down and help you gain weight.
Steps
-
Gain weight by eating more calories than your body burns. Regardless of your metabolic rate, you're not going to gain weight unless you're consuming more calories than your body needs to function. This is one of the reasons why knowing your BMR is extremely important. Without that number, you have no way of knowing how many calories you should be eating on a daily basis to achieve a calorie surfeit. [2] X Research source

2Choose high-calorie and nutrient-dense foods from each food group. For example, natural foods high in complex carbohydrates have been shown to reduce diet-induced thermogenesis (DIT) compared to more processed foods by reducing sympathetic and melanocortin activity via an intricate neuroendocrinological mechanism. [3] X Research source [4] X Research source [5] X Research source [6] X Research source [7] X Research source [8] X Research source [9] X Research source [10] X Research source [11] X Research source By contrast, eating foods that are hard to digest may increase the thermic effect of food (TEF) by increasing digestion energy costs and/or may contribute to fecal energy losses. [12] X Research source In rodent studies, high-sucrose diets are consistently shown to increase proton leak, Krebs cycle activity, and resting energy expenditure (REE).

[19] X Trustworthy Source Nature Respected Multidisciplinary Scientific Journal Go to source This may cause rebound hypoglycemia due to overproduction of insulin, thereby activating a stress response that increases sympathetic activity, raises free fatty acid (FFA) levels, and actually stimulates the catabolism of fat and muscle stores.

Certified Nutritionist Expert Interview [32] X Research source [33] X Research source Diets too low in carbs may potentially increase REE and render weight gain less efficient by raising energy costs associated with hepatic glucose synthesis. Fructose itself has a low glycemic index (GI), is metabolized slowly, and is efficiently stored as body fat, and dietary saturated fats can be readily stored as well since they closely resemble the body's own lipids. A high intake of saturated fats like beef tallow may reduce proton leak and sympathetic activity. High levels of insulin also produce anabolic effects, especially when simple carbs are consumed after workouts, but overexposure to insulin may diminish insulin sensitivity over time. By contrast, eating foods that are difficult to digest (e.g., hard cheeses) may increase DIT and/or fecal energy losses. [34] X Research source [35] X Research source - Focus on foods that are rich in high-quality, slowly metabolizable complex carbohydrates, such as rice, bread, and pasta, along with starchy vegetables such as beans, peas, corn, and potatoes. Also, emphasize foods rich in high-quality fats and proteins, such as red meat, salmon or oily fish, and higher-fat dairy products. Pasta (especially in the whole-wheat varieties) is particularly good because it's a low GI complex carbohydrate and may reduce DIT. [36] X Research source [37] X Research source These kinds of foods promote better cardiometabolic health, maintain serum insulin levels over longer periods, and help you gain weight without potentially damaging your health.
- Prefer solid, nutrient-dense whole fruits (e.g., apples, bananas, grapes, and berries) for their natural soluble fiber and more complex physical structures. [38] X Trustworthy Source Science Direct Online archive of peer-reviewed research on scientific, technical and medical topics Go to source [39] X Research source Some fruits (like strawberries, pears, and peaches) contain beneficial flavonoids that also may produce a small antithyroid effect. The nitrates, resveratrol, soluble fibers (e.g., pectin), serotonin, melatonin, and iodine naturally present in some fruit and vegetable juices (e.g., beetroot, tomato, cranberry, tart cherry, or prune) and whole fruits may potentially decrease resting energy metabolism.

- Consider meats that are higher in fat, such as steak, pot roast, pork chops, and chicken or turkey thighs. [48] X Trustworthy Source Cleveland Clinic Educational website from one of the world's leading hospitals Go to source They're also rich sources of iron and selenium, nutrients that help promote good thyroid health, and a high selenium diet has been shown to reduce levels of triiodothyronine (T3) and enhance gain in lean muscle mass in some studies. [49] X Trustworthy Source Science Direct Online archive of peer-reviewed research on scientific, technical and medical topics Go to source When you're looking to gain weight, increasing your fat intake a little may help decrease your metabolism by reducing DIT and sympathetic activity and by allowing for efficient deposition of the extra calories. [50] X Research source Increasing healthful fats in the diet can also increase the overall calorie density of the diet and make foods more palatable, making it easier to take in enough calories without feeling uncomfortably full.
