Please do Kapalbhati pranayam as suggetsed by baba Ramdev in Aastha channel for 10 minutes daily
you should eat at least 4-5 meals a day.drink lots of water, and eat regularly. don t starve yourself, because once you start eating again, you ll gain everything back, trust me.eat lots of fruits and veggies, and if you eat bread, make sure it s whole grain. white bread is pretty fattening. you can also eat lean meats, like fish, turkey and chicken breast. eggs also help when trying to lose weight.skip out on sweets, candy, sugary foods, chips, ice cream, cake, and cookies.if you feel hungry, but don t want to over eat, chew gum. it ll keep your mouth busy and it tricks yourself into thinking your eating.cut out ALL soda! if you stop drinking soda, it helps you out a lot!and don t forget to exercise!try walking, jogging, jump rope, dancing, crunches, bike riding and swimming. try exercising for 45-80 minutes a day.good luck!
Well, fast, ya starve yourself. But if you have to eat I spose you can stop eating stuff with corn syrup and well, eating vegan couldn t hurt :P
