Weight-loss at 70

I have been overweight since my third child was born in 1973. I've tried a multitude of weight loss plans, programs, and fads. I even considered bypass surgery when I got to 300 pounds. I started keto with Dr Berg about a year and a half ago at 285 pounds. I became a widow in 2018 and as usual I used food in my grieving process. I had become pre-diabetic, borderline hypertensive, and on the verge of cholesterol medication as well. I started watching Dr Berg's videos on line and they made so much sense. I have lost 100 pounds now and I will be 71 in October. Thank you!
