Bro-scientists will insist that eating small portions every 2-3 hours will increase your metabolism. They base this on the thermic effect of food (TEF), which refers to the energy (calorie) cost of your body processing the food you consume. On average, 15 percent of the calories you consume are burned by processing them (although the rate varies by macronutrient). Someone took this idea and assumed that the more frequently people consume their meals, the more frequent TEF will take effect and thus increase fat oxidation.
Every gym has the guy or girl who does an hour and half of cardio but never seems to make physique changes. They're living proof that if you don’t change things up, steady-state cardio will become less and less effective at reducing your body fat.
Fats and carbs both play a role in fat loss. Fats are responsible for hormone production, joint lubrication, and many other important health and muscle-building factors. Dropping your fats too low could compromise your health and your goals. Everyone's body and metabolism is different, so it's crucial to know how many grams of healthy fat you need to eat for a balanced nutrition regimen.
