It is impossible for fat to directly turn into muscle, since fat lacks the nitrogen and no mechanism exists in the body to reconstruct fat into amino acids. No evidence has surfaced implying that amino acids can be made in the body from anything other than other amino acids, a process known as transamination.
Can fat turn into muscle? We're sorry to disappoint, but no, fat cannot turn into muscle. Fat and muscle are two completely different things, and your body can't turn one into the other. You can lose fat and gain muscle (or gain fat and lose muscle), but one does not magically transform into the other.
Yes, you can lose body fat and gain muscle simultaneously while maintaining the same weight. This happens because muscle is denser than fat, meaning it takes up less space but weighs the same. Focus on strength training, protein-rich meals, and maintaining a calorie balance.
Fat can neither become protein nor glucose. No pathway for the synthesis of either from fatty acids. An overweight person should eat protein in their diet to maintain muscle mass while restricting calories from other sources.
And those with a higher percentage of body fat have more energy to spare and gain muscle. A higher body fat percentage also means that your body is likely more insulin resistant, a condition in which your fat cells resist taking on more calories, so the energy is diverted toward muscle.
As your body metabolizes fat, fatty acid molecules are released into the bloodstream and travel to the heart, lungs, and muscles, which break them apart and use the energy stored in their chemical bonds. The pounds you shed are essentially the byproducts of that process.
During any weight loss journey, it's common to lose a bit of muscle mass along with fat. “This is true of any weight loss regimen,” says Kate Gdovin, a physician assistant certified in obesity and weight management. “When you lose weight, you inevitably lose some muscle mass.”
Working out can cause short-term weight gain as your muscle mass increases. Post-workout inflammation may cause temporary weight fluctuations. Workout plateaus, supplement use, and dietary changes can also stall your weight-loss efforts. Try not to obsess over the number on the scale.
Strength training helps you lose weight and keep it off by building muscle tissue. The more muscle mass you have, the higher your metabolic rate tends to be. More muscle also helps your body burn more fat than muscle, which is important if you want to lose weight and keep your strength.
However, skipping a workout here and there typically doesn't cause weight gain, and taking regular rest days is healthy for muscle recovery and preventing injury.
Lean protein and fiber are the building blocks of healthy eating that help shed belly fat and gain muscle. Plus, the combination of fiber and lean protein will fill you up without blowing your calorie budget. A balanced diet also includes healthy fats, fresh veggies, and fruit, along with dairy or dairy alternatives.
The Scale is Going Up
The first sign that you're building muscle may be an increase in body weight. The number on the scale goes up because muscle tissue is denser and heavier than fat. Therefore, it takes up less space for the same amount of weight.
Muscle is denser (meaning a lot less fluffy) than fat, says Dr. Calabrese. Put another way, 10 pounds of muscle takes up a lot less space than 10 pounds of fat. So, as you start working out regularly and building strength, the new muscle you build may eventually weigh more than the fat you've burnt off.
If you're asking yourself, “Why am I gaining weight when I barely eat,” several factors may be at play. Your body may be holding onto fat stores if your eating habits are inconsistent or restricted. Or, your weight gain may be the effect of a sedentary lifestyle, medical condition, or long-term stress.
Your body weight includes the mass of your body fat and a fat-free mass, or lean body mass – your muscles, bones, organs, and water (1). A very real possibility is that when you notice that you are losing weight but look fatter, there is a high chance that you only lost water weight or muscle mass, or both.
After hepatic glycogen stores are depleted, the body uses adipose tissue and protein for energy. The liver has an active role in the metabolism of fats as it is the main oxidizer of triglycerides. In more extreme versions of fasting, where fat sources have been expended, the body breaks down skeletal muscle for energy.
“When people are eating too few calories or exercising a lot while trying to lose weight, the body reverts into a state of metabolic adaptation.” Metabolic adaptation is a survival defense mechanism that our bodies revert to when deprived of food.
The “love handles,” thighs, and abdomen contain fat cells that the body uses as energy stores, making them physiologically resistant to exercise and diets. These areas are the last to respond or may not change at all.
Mostly, losing weight is an internal process. You will first lose hard fat that surrounds your organs like liver, kidneys and then you will start to lose soft fat like waistline and thigh fat. The fat loss from around the organs makes you leaner and stronger.
