I have been on a low carb diet for a while and want to cheat…will I gain all the weight back?
No you will not gain back fat that you’ve lost with one meal. But you will most likely gain weight back, but much of it will be the water that comes with the carbs. You might also get ‘sick’ feelings. Common symptoms of “carb overload” after having been off large quantities of carbs for some time would include headache, gas, bloating, fluid retention & swelling, etc.
