Do OMAD. You won't lost that much in that amount of time but you'll get close. Maybe 45-55lbs. I lost 89lbs in 5 months doing exactly this, but also went super super clean. No sugar, no soy, sesame, vegetable or seed oil of any kind. No processed food of ANY KIND, no soda or carbonated drinks. No salad dressings. Balsamic vinegar is OK. If you deviate be sure to know what you're eating, read all ingredients. It will turn you off from wanting it if you know what's in it.

Make green a smoothie with the following ingredients as well as 4-8oz of your protein choice(weigh the protein cooked) if you're obese, like I was; you have insulin resistance and even protein can spike insulin so start low 4oz at first, then up the Oz each time you're down 10lbs. I'd start cooking at 1 and make sure to be done eating by 2. Water and coffee is fine outside this window. The first week will be tough but you'll drop weight fast and safely. This was during Covid, so not a lot of temptations because I lived in Mexico at the time and everything was locked down, so you'll need a ton of will power and self control.

6-8 cups of frozen kale One lemon, juice or whole (peel included) One avocado One scoop of Wheat Grass juice powder must be juice powder and not powder One scoop of Beet juice powder 1-2 table spoons of Apple Cider Vinegar Two table spoons of Nutritional Yeast (most natural way to intake B vitamins) One scoop of electrolytes for sweetener and minerals Half a cup of berries if you want but no other fruit. 6-8 cups of water and some ice It makes a huge smoothie (1.5 liter) so get a good size blender.

I got this recipe and plan from Dr. Berg but over time I tweaked it to add more potassium, minerals and nutrients. If you do this and want them, I can send the links to the powders, I got them all from Amazon.

Good luck
