Hi, T-Dog. No, a low-carb diet is not necessary to drop BF, though a lot of BBs do cut carbs to get to low BF percentages for competition. There are any number of diets here on T-Mag. All that is REALLY necessary is that you’re hypo-caloric (i.e., below maintenance calories).
Myself, dropping BF is extremely difficult/challenging. I’m extremly insulin INsensitive. It’s a genetic thing. A number of people in my family are/were diabetic and died from complications due to diabetes. So even though I do well on a low-carb diet, you may not need to do low carbs to drop weight/BF.
There’s a lot more to T-Dawg than meets the eye. For one thing if you change from a free-feeding type of approach to life to restricted carbs, you’re also cutting the insulin that’s secreted. And what’s the big deal about avoiding chronically high levels of insulin? Well, when insulin is present, any fat eaten with it is immediately stored. Additionally, fat mobilizing hormone cannot be present at the same time insulin is present. Low levels of insulin and/or timed spikes results in your body drawing upon fat reserves to a greater degree.
All I can say is experiment. If you continue to lose weight, that’s all that matters. If you stop losing weight/BF, go back to T-Dawg basics.
