First, congratulations on maintaining your weight. I understand the desire to lose even more. I like that you used the term “modified”. I am not on a keto
diet but I have eliminated a lot of carbs (especially white flour) from my daily diet now for several years, not for weight loss, but for a healthier approach to eating. I know people who have lost weight on this diet but it is not always easy to sustain. I have a friend who is on the dirty vs the clean keto diet and she has lost a few pounds of water and not much else. She really needs to cut back on calories and carbs.
I have never liked or trusted any weight loss pill. They are not backed by any scientific or medical proof and are not overseen by the FDA. Also, unnecessary supplements are added. I personally think it is a waste of money and may interfere with any any other medications you may be taking and or your metabolism. I don’t always trust that the contents match the labels.
You sound like you are on the right track….it’s a long road to lose weight but once you change your eating habits and lifestyle you’ll never go back to the old ways. You’ll feel and think better. Diet pills are not going to do that for you. What happens once you’re off them?
