I am fatty boy. My weight is 125 kg. What will happened if I take only mid day meals?

If this 'one meal' is larger than your current daily intake, you will gain weight.

Your body will go into starvation mode and store MORE calories.

Eat FREQUENT SMALL HEALTHY meals and EXERCISE.

Dieting + Exercise not just one!

I ate once a day for 30 years (dinner) and stayed slim and active, I am now retired and sometimes eat 2 times a day but I'm putting on weight.
