I found the calories of yogurt from many websites: 1, and the calories of yogurt and fruit yogurt are 65-75 calories/100g; 2, skim yogurt 45-57 calories/100g. If you want to lose weight or keep fit, the difference between your daily calorie consumption and intake should be 1000- 1500 calories ~ normal people (generally people aged 20 -30): it is normal to consume about 2000 calories a day, 500-800 calories.
