I know how to lose weight really fast. I used to do it for bodybuilding in the summers and spring, I would eat a high protein and moderate carb and zero fat diet and exercise like normal. I would have a six pack in a month and keep it until the fall, then I would have a four pack. I had virtually no fat, I was really quite a sight in the summers. In the fall and winter I was one inch bigger in the waist
Now I have to eat normally but for my first competition in the fall or summer (havent decided when to compete) I might have to eat very strictly, high protein, moderate carbs and almost zero fat to lose a few lbs to make the 165 weigh-in. right now I am 168 hydrated in the afternoons.
I might just not adjust my diet and dehydrate in order to lose the weight for a weigh-in like boxers and MMA fighters do. Powerlifters and fighters are known to drop 20lbs in water and poop and food in like 3 days to make weigh-ins. I read about a heavyweight powerlifter dropping 35lbs and making a 220lb weigh-in, then his stats were off the chart because he was actually 255.
But whatever dont just lose weight on the scale, burn fat with a strict diet and exercise. It’s safe to dramatically cut down your calories as long as you eat enough with your meds, some meds MUST be taken with at least 400 calories or they dont work as well and might just leave you with an episode.
I used to be obsessed and was even anorexic for about 6 months when I was 16. Basically, you are what you eat- a plate full of tuna, black beans and brown rice is basically muscle and carbs. A slice of pizza is mostly fat and processed carbs, which are digested too quickly (high glycemic index) and can make you fat. Generally speaking, brown carbs are better, they have fiber and low glycemic indexes and wont just go to your stomach and hips.
