It’s not all fat you’re gaining relax!

Always remember there are approximately 3,500 calories in half a kilo (1 pound) of pure body fat. This means that to gain 0.5 kg of body fat, you would need to consume 3,500 calories above your maintenance calories, which is the amount of energy your body needs to maintain its current weight based on your activity level and metabolism.

However, gaining weight doesn’t happen instantly or exactly like this for several reasons:

1. Energy Partitioning: Not all excess calories turn into fat. Some may be used to build muscle, especially if you’re engaging in resistance training or if your body is in a muscle-building phase.

2. Water Retention: Rapid changes in weight are often due to fluctuations in water retention, glycogen stores, or the contents of your digestive system rather than an actual gain in fat.

3. Daily Variability: Calorie intake and expenditure fluctuate daily. A single day of overeating is unlikely to lead to a significant fat gain unless it becomes a consistent pattern.

4. Metabolic Adaptations: Your body may increase thermogenesis (calories burned through heat production and activity) when you consume excess calories, especially if you’re highly active.

This is why it’s crucial to look at long-term patterns rather than obsessing over short-term fluctuations on the scale. Fat gain or loss happens over time as a result of sustained calorie surpluses or deficits.

So, even if you overindulge on one day, it doesn’t mean you’ve permanently gained fat. A return to your regular eating and activity patterns will typically balance things out.
