Foods to avoid

To maintain muscle mass and to prevent increase in body fat, people with a mesomorph body type should avoid eating food that could delay their health goals. These foods include:

  • Foods with high fat content, like fried foods, margarine, pizza, bacon, chips, and hamburgers
  • Cured meat and sausages, hot dogs, sausages, rump roast, prosciutto, mortadella and salami
  • Refined grains, like white rice, white bread or white pasta
  • Processed foods, like packaged cookies, instant noodles, sodas, ready-made sauces or seasoning, and fast food

It is important to avoid consumption of alcoholic drinks (like beer or wine) as these are high in calories and will lead to fat gain. Alcohol can also decrease circulating testosterone levels, and this hormone is important for muscle gain.
